What Lariam is used for
Lariam is used to prevent and treat malaria.
Lariam contains the active ingredient mefloquine. Lariam belongs to a group of medicines called quinolones (pronounced kwin- o-lones).
Lariam works by killing the parasites that may cause or have caused malaria.
Where and how you can contract malaria
Malaria is an infectious disease that is widespread in tropical and subtropical areas of Africa, Latin America, Asia and countries around the Pacific. There are different forms of malaria, each of them caused by a specific parasite transmitted to humans by the bite of the Anopheles mosquito.
Precautions against malaria
The best protection against malaria is to avoid mosquito bites. The mosquito that causes malaria mainly bites between dusk and dawn. Therefore the following precautionary measures are recommended:
- during this period, wear light- coloured clothing that covers as much of your skin as possible
- apply mosquito repellent to your uncovered skin and to your clothes
- when sleeping in rooms that are not protected against mosquitoes, use an effective mosquito net well tucked under the mattress
- additional protection is provided by smoke spirals, insect sprays and candles.
Symptoms of malaria
The symptoms of malaria may often be mild. However, malaria should be suspected if, after one week in a malarial area, you suffer unexplained fever with or without other symptoms such as headache, aching limbs, weakness, shaking, chills, and sometimes diarrhoea, vomiting and cough. These symptoms can easily be confused with influenza.
If these symptoms are due to the most dangerous form of malaria caused by the falciparum parasite, and they are not treated in time, severe organ damage, loss of consciousness and death can occur within a short period. The less dangerous forms of malaria, which are not life threatening, can break out months or even years after the end of a stay in a malarial area.
Diagnosis and treatment of malaria
Early diagnosis is critical for successful treatment. Anyone suspected of having malaria should seek medical attention promptly and request that a blood sample be taken and examined microscopically for malaria parasites.
Most tourists and business travellers will normally be able to receive medical attention. However, if this is not readily available, anti-malarial drug treatment can be self- administered ('stand-by treatment').
Consult your doctor about the need to carry 'stand-by treatment' on your trip. Medical advice should still be sought after self-administered drug treatment.
There are many different types of medicines used for the treatment and prevention of malaria.
Your doctor may have prescribed Lariam for another purpose.
Ask your doctor if you have any questions about why Lariam has been prescribed for you.
Lariam is not addictive.
This medicine is available only with a doctor's prescription.
