Travel health information for people travelling abroad from the UK


fitfortravel' is a public access website provided by the NHS (Scotland). It gives travel health information for people travelling abroad from the UK. Remember that you should always discuss your particular needs with your own doctor or nurse.

The website is compiled by a team of experts ts from the Travel Health division at Health Protection Scotland (HPS).- for example - good guidance on malaria:

Introduction

Malaria is widespread in many tropical and subtropical countries and is a serious and sometimes fatal disease. You cannot be vaccinated against malaria, but you can protect yourself in three ways:

Avoidance of Bites

Mosquitoes cause much inconvenience because of local reactions to the bites themselves and from the infections they transmit. Mosquitoes spread malaria, yellow fever, dengue and Japanese B encephalitis.

Mosquitoes bite at any time of day but most bites occur in the evening.

Precautions to Take

  1. Avoid mosquito bites, especially after sunset. If you are out at night wear long-sleeved clothing and long trousers.
  2. Mosquitoes may bite through thin clothing, so spray an insecticide or repellent on them. Insect repellents should also be used on exposed skin.
  3. Spraying insecticides in the room, burning pyrethroid coils and heating insecticide impregnated tablets all help to control mosquitoes.
  4. If sleeping in an unscreened room, or out of doors, a mosquito net (which should be impregnated with insecticide) is a sensible precaution. Portable, lightweight nets are available.
  5. Garlic, Vitamin B and ultrasound devices do not prevent bites.

Taking Anti-Malaria Tablets

  1. Start before travel as guided by your travel health advisor (with some tablets you should start three weeks before).
  2. Take the tablets absolutely regularly, preferably with or after a meal.
  3. It is extremely important to continue to take them for four weeks after you have returned, to cover the incubation period of the disease. Atovaquone/proguanil (Malarone) requires only 7 days post-travel)

Drugs Most Commonly Used for Malaria Prevention

Travellers must always, through discussion with their doctor or pharmacist, make sure they use a drug which they can tolerate (only the more common side effects are given here) and one which is appropriate for their destination(s). No drug is 100% effective.

In Britain, chloroquine and proguanil can be purchased from local pharmacies or chemists. All other drugs require a doctor's prescription.

Chloroquine (licensed for prophylaxis in UK)

  • Preparations available: Avloclor® (Zeneca) and Nivaquine® (Rhône-Poulenc Rorer). Adult dose is 2 tablets (each containing 150mg chloroquine as base) taken once a week. Nivaquine is available in syrup form.
  • Consider a trial course before departure, if using this regime for the first time, to detect if you are likely to get side effects (e.g. for two weeks). Otherwise, when possible, chloroquine should be started one week before exposure (to ensure adequate blood levels), throughout exposure and for 4 weeks afterwards.
  • Nausea and sometimes diarrhoea can occur which may be reduced by taking tablets after food.
  • Headache, rashes, skin itch, disturbance of visual accommodation (often expressed as blurred distance vision which may take up to 4 weeks to reverse) or hair loss may warrant changing to alternative drugs.
  • Retinopathy (eye changes) which can be permanent is unlikely to occur until 100g have been consumed (i.e. over 5 years treatment at prophylactic doses).
  • Caution in liver and renal disease.
  • Can aggravate psoriasis and very occasionally causes a convulsion so it should not normally be used in those with epilepsy.
  • Chloroquine is very toxic in overdose - parents must take special care to store the tablets safely.
  • It is generally accepted, as a result of long usage, to be safe in pregnancy.

Proguanil (licensed for prophylaxis in UK)

  • Preparations available: Paludrine® (Zeneca). Adult dose is 200mg daily.
  • Can normally be used continuously for a period of up to 5 years.
  • One or two doses should be taken before departure. It should be continued throughout exposure and for 4 weeks afterwards.
  • Anorexia, nausea, diarrhoea and aphthous (simple) mouth ulcers can occur.
  • Can delay the metabolism of the anticoagulant, warfarin, and result in bleeding. Those planning to take warfarin must discuss this with their doctor before starting any treatment.
  • Caution in renal impairment.
  • Considered to be safe in pregnancy, but folate supplement is advised.

Mefloquine® (licensed for prophylaxis in UK)

  • Preparations available: Lariam® (Roche). Adult dose is 250mg weekly.
  • One dose should be taken a week before departure and it should be continued throughout exposure and for 4 weeks afterwards however three (3) doses at weekly intervals prior to departure are advised if the drug has not been used before - this can often detect, in advance, those likely to get side effects so that an alternative can be prescribed.
  • Not licensed in Britain for use for more than 1 year (in countries where it is licensed for more than 1 year, additional side-effects are rare).
  • Nausea, diarrhoea, dizziness, abdominal pain, rashes and pruritis can occur.
  • Headache, dizziness, convulsions, sleep disturbances (insomnia, vivid dreams) and psychotic reactions such as depression have been reported. These reactions most commonly begin within 2-3 weeks of starting the drug and may be worse if alcohol is taken around the same time as the mefloquine.
  • Avoid in epilepsy, if there is a close family history of epilepsy (e.g. parents or siblings) or if there is a history of psychiatric illness.
  • Caution, and avoid if alternatives are available, in severe renal or liver failure and those with heart rhythm defects. Also caution in those taking digoxin, beta or calcium channel blockers when arrhythmias and bradycardia can occur.
  • Although there is no evidence to suggest that mefloquine has caused harm to the foetus it should normally be avoided during the first trimester of pregnancy or if pregnancy is considered possible within 3 months of stopping prophylaxis.

Doxycycline (licensed for prophylaxis in UK)

  • Preparations available: Doxycycline (non-proprietary), Vibramycin® (Invicta). Adult dose is 100mg daily.
  • Can normally be used continuously for a period of at least 6 months - be guided by your doctor.
  • Consider a trial course before departure, if you are using this regime for the first time, to detect if you are likely to get side effects (e.g. for one week). Otherwise doxycycline need only be started just before exposure (e.g. 2 days), continued through exposure and for 4 weeks afterwards.
  • When other tetracyclines are being already used for acne this will provide protection against malaria so long as an adequate dose is taken (you can change to 100mg doxycycline per day if your doctor agrees).
  • Erythema (sunburn) due to sunlight sensitivity can occur. Use of sunscreens is especially important and if severe, alternative prophylaxis should be used.
  • Heartburn is common so the capsule should be taken with a full glass of water and preferably while standing upright.
  • Contraindicated in pregnancy (including one week after completing the course), breast feeding, in those with systemic lupus erythematosis, porphyria and children under 12 years because permanent tooth discoloration can occur.
  • It may reduce the effectiveness of the oral contraceptive pill, you should discuss this with your family planning advisor.
  • Occasionally anorexia, nausea, diarrhoea, candida infection and sore tongue (glossitis) have been reported and rarely hepatitis, colitis and blood dyscrasias.

Atovaquone plus proguanil (licensed for prophylaxis in UK)

  • Preparations available: Malarone®. Adult dose is one tablet daily - each tablet contains 250mg atovaquone plus 100mg proguanil. Child doses will be based on the weight of the child but will be once daily also.
  • DO NOT confuse with Maloprim® which is not now advised for prophylaxis since more effective alternatives are available.
  • Should be taken for 1 or 2 days before entering the malarious area, throughout exposure, and for 7 days after leaving the infected area. Licensed for trips of up to 28 days but there is no evidence of increased side-effects if used for longer.
  • Atovaquone/proguanil need only be commenced one or two days before exposure.
  • Abdominal pain, headache, anorexia, nausea, diarrhoea, coughing and aphthous (simple) mouth ulcers can occur.
  • Absorption may be reduced in diarrhoea and vomiting, and blood levels are significantly reduced with concomitant use of tetracyclines, metoclopramide and especially rifampicin or rifabutin.
  • The proguanil component can delay the metabolism of the anticoagulant, warfarin, and result in bleeding. Those planning to take warfarin must discuss this with their doctor before starting any treatment.
  • Caution in renal impairment.
  • Lack of experience in pregnancy and during breast feeding means that it should be avoided in these circumstances unless there is no suitable alternative.
  • The high cost makes popular for short trips.

Prompt Treatment

Following these guidelines faithfully might not guarantee complete protection. If you get a fever between one week after first exposure and up to one year after your return, you should seek medical attention and tell the doctor that you have been in a malarious area.

Oral grass pollen vaccine Grazax

Press release September 26 2006

Grazax(R) Tablet-Based Vaccine Against Grass Pollen Allergy Approved in Europe
Authorities in 27 European countries approved ALK-Abelló's tablet-based vaccine against grass pollen allergy, Grazax®
-
the first allergy tablet to address the underlying cause of the disease.

Further information at http://www.wansford.co.uk/grazax/

ALK-Abelló expects to launch the innovative and convenient treatment on the first European markets by the end of 2006, ahead of the 2007 pollen season.

HØRSHOLM, DENMARK -- -- ALK-Abelló completed the European Mutual Recognition Procedure for Grazax, the company's tablet-based vaccine against grass pollen allergy, and authorities in 27 European countries have now approved the tablet treatment The Swedish authorities approved GRAZAXGrazax® in March 2006. The approval now also covers Austria, Belgium, Cyprus, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, the Czech Republic, the Netherlands and the United Kingdom..
"We are very pleased to complete the European Mutual Recognition Procedure with such a positive result. This is a decisive step towards the launch of Grazax. We now look forward to ensuring many more grass-allergic patients in Europe benefit from Grazax treatment, with reduced allergy symptoms and improved quality of life," says Jens Bager, CEO of ALK-Abelló A/S.

Grazax treats the cause of allergyGrazax is the first allergy tablet that improves patients' quality of life by treating the underlying cause of grass pollen allergy and not just the symptoms. Clinical studies show that Grazax has a good safety profile and provides significant efficacy within the first season of treatment. In a global evaluation of patients' perceptions of efficacy of Grazax® treatment, 82 percent of the patients felt 'better' or 'much better' in the first season of treatment, compared with the previous pollen seasons.
Grass pollen allergy is a health problem representing a significant social burden. At least 45 million people in Europe suffer from grass pollen allergy in the shape of allergic rhinitis (hay fever) or allergic asthma – or both.

The majority of patients are only offered symptomatic medications that do not treat the allergy itself. According to a survey conducted by the European Federation of Allergy and Airway Diseases Patients Associations (EFA), 70% of allergic patients feel that allergy limits their quality of life, and 60-68 percent perceive symptomatic medications to be in the range of 'not at all effective' to 'moderately effective' on individual symptoms.
For patients, Grazax is an innovative and convenient treatment formulated as fast-dissolving once-a-day sublingual tablets that can be taken at home. This convenient formulation means that many more patients are expected to be offered the possibility of a medicine that treats the underlying cause of their allergy.

ALK-Abelló expects to launch Grazax on the first European markets by the end of 2006, ahead of the 2007 pollen season. These launches may commence immediately upon receipt of local marketing authorizations and following finalization of price and subsidy negotiations with the respective authorities. The timing of this process will vary from country to country.
Grazax® is a trademark owned by ALK-Abelló A/S.

New guidance for treating heavy periods

Treatment and care for women with heavy periods
(updated 24th Juanuary 2007 - from NICE (National Institute of Clinical Excellence) Link to advice for Health professionals)
Are heavy periods disrupting your life?
Every woman is different and the amount of blood each woman loses during her period varies widely from one person to another. If heavy periods are disrupting your life, your doctor should be able to offer treatments to help.
First stop: your doctor
Your doctor will ask you about your periods, how much bleeding you have (how often you need to change your tampons/sanitary pads, whether you have clots or experience flooding) and how long your period lasts. If you bleed after sex or have pelvic pain or bleeding between periods, your doctor should offer to examine you to try and find out the cause.
Tests
Your doctor may offer tests to try and find out what is causing your heavy periods. A blood test will show the doctor if you have anaemia (not enough iron in your blood).
If your doctor is concerned about the cause of your heavy periods, you may be offered an ultrasound scan. If the scan doesn’t show anything is wrong or is unclear, you may be offered other types of tests. Your doctor may offer to refer you to a specialist if there seem to be large fibroids or other problems with your womb. (A fibroid is a non-cancerous growth in the womb.)

Drug treatments
If there are no obvious problems with your womb, your doctor will be able to offer a number of different drug treatments to help you. Some of the treatments are also contraceptives. The options are listed on the table on the next page in the recommended order. Your doctor should discuss the benefits and risks of each treatment with you. If the first treatment isn’t suitable for you, or if you try one treatment and it doesn’t work, it may be possible to try the next option. Some of the treatments make your periods lighter and some may stop the bleeding completely. You should be given information explaining the different options, and be allowed time to make your decision.

If you think that your care does not match what is described in this leaflet, please talk to a member of your healthcare team.Second stop: your specialist
If treatments offered by your doctor haven’t worked, or if you have large fibroids or other possible problems with your womb, you may be offered a referral to a specialist. Before your appointment you should be given this leaflet or other similar information.
Surgical treatments
Your specialist may offer you surgery. There are a number of different operations that can help (see the table on page 6). Your specialist should discuss these with you. You should be told about the benefits and risks of each option, and given enough time and support to help you make a decision. Some operations will affect your fertility, and before making a decision about these operations your specialist should discuss in detail the potential impact on you.
Your specialist should be competent in the procedures offered. If your specialist is not trained to undertake a particular treatment you should be referred to another specialist with this training.

Questions you might like to ask your doctor
Please give me more details about any tests I may need.
How long will it take to have the tests and get the results?
Please tell me why you have decided to offer me this particular type of treatment.
What are the pros and cons of having this treatment?
How will the treatment help me? What effect will it have on my symptoms and everyday life? What sort of improvements might I expect?
How long will it take before I notice a difference?
Are there any risks if I take this treatment?
What are my options for taking treatments other than the recommended treatment?
Is there some written information about the treatment that I can have?

Types of surgery in recommended order – some types may not be suitable for you
What is it?
How does it work?
Could it affect my chance of getting pregnant in future?
Possible unwanted effects (not everyone experiences these)
See note at bottom of table
Surgery to remove the lining of the womb (endometrial ablation). There are several different methods. The following are recommended: • ‘thermal balloon endometrial ablation’ (TBEA) • ‘impedance-controlled bipolar radiofrequency ablation’ • ‘microwave endometrial ablation’ (MEA) • ‘free fluid thermal endometrial ablation’.
But other techniques (for example, rollerball ablation) may be more suitable if you have fibroids or other problems with your womb
In all of these techniques a device is inserted into the womb through the vagina and cervix. The device is heated using different methods (for example, using microwave or radio energy). This heat destroys the lining of the womb
Removing the womb lining should stop bleeding. In some women the lining grows back and the surgery may need to be repeated
This surgery is not suitable if you want to become pregnant at any time in the future
You will need to use contraception if you have sex
Common: vaginal discharge; increased period pain or cramping (even if no further bleeding); need for additional surgery
Less common: infection
Treatment to block the blood supply to fibroids (uterine artery embolisation or UAE)
Small particles are injected into the blood vessels that take blood to the womb
The blood supply to the fibroids is blocked and this causes them to shrink
You may be able to get pregnant after this procedure
Common: long-lasting vaginal discharge; pain; nausea; vomiting; fever
Less common: need for further surgery; premature ovarian failure particularly in women over 45 years; collection of blood
Surgery to remove fibroids (myomectomy)
This can be done either through a cut in your abdomen or through your vagina
When the surgery is done through the vagina, a thin telescope (called a hysteroscope) is used to see inside your womb
Fibroids can cause heavy periods, and removing them should reduce the amount of bleeding
You may be able to get pregnant after this procedure
Less common: internal scars (which may lead to pain and/or impaired fertility); need for additional surgery; recurrence of fibroids; perforation (hysteroscopic route); infection
Surgery to remove the womb (hysterectomy). There are two main ways of doing this depending on your individual circumstances.
Hysterectomy should only be considered when:• Heavy bleeding has a severe impact on your quality of life • Other treatments haven’t worked or are not suitable for you • You want your periods to stop completely • You fully understand the risks and benefits and ask for a hysterectomy • You don’t want to keep your womb or to have a child
Your ovaries should not be removed if they are healthy. If you or your specialist have concerns, or you are considering having your ovaries removed, all the options should be discussed. If you have a strong family history of ovarian or breast cancer you should be offered genetic counselling
• Vaginal hysterectomy: the womb and cervix are removed through the vagina• Abdominal hysterectomy: the womb is removed through the abdomen – In a ‘total’ hysterectomy, all of your womb and cervix is removed. In a ‘subtotal’ hysterectomy, just the womb is removed – In laparoscopic hysterectomy, a device with a camera and cutting tool is used
Removing the womb means you won’t have a period again
If you have fibroids there is an increased risk of complications, your specialist should discuss this with you
There is no chance of having a child after a hysterectomy
Common: infection
Less common: excessive bleeding during surgery; damage to other abdominal organs, for example, urinary tract or bowel; urinary dysfunction – frequent passing of urine and incontinence
With ovary removal at time of hysterectomy:
Common: menopausal-like symptoms (for example, hot flushes, increased sweating, vaginal dryness)
Note: The most common unwanted effects may be experienced by 1 in 100 women. Less common unwanted effects are those experienced by 1 in 1000 women. Rare unwanted effects are not shown here.This table does not cover all the pros and cons of each option. Your specialist should discuss both the short- and long-term effects in detail.
Your care
Your treatment and care should take into account your personal needs and preferences, and you have the right to be fully informed and to make decisions in partnership with your healthcare team. To help with this, your healthcare team should give you information you can understand and that is relevant to your circumstances. All healthcare professionals should treat you with respect, sensitivity and understanding and explain heavy periods and the treatments simply and clearly.
The information you get from your healthcare team should include details of the possible benefits and risks of particular treatments. You can ask any questions you want to and can always change your mind as your treatment progresses or your condition or circumstances change. Your own preference for a particular treatment is important and your healthcare team should support your choice of treatment wherever possible. You should be able to get a second opinion if an agreement between you and your healthcare professional on your treatment is not reached.
Your treatment and care, and the information you are given about it, should take account of any religious, ethnic or cultural needs you may have. It should also take into account any additional factors, such as physical or learning disabilities, sight or hearing problems, or difficulties with reading or speaking English. Your healthcare team should be able to arrange an interpreter or an advocate (someone who supports you in asking for what you want) if needed.

You should not be offered:
oral progestogens for use only in the second half of your menstrual cycle
drugs called danazol and etamsylate
dilatation and curettage (D and C, which involves scraping out the womb lining) – as a treatment or test
