Lariam (Mefloquine) is an effective antimalarial medication with the added benefit of only needing to be taken once weekly rather than daily. This makes it a popular choice amongst travellers, as you do not need to remember to take your tablets daily.

What Lariam is and what it is used for

Lariam tablets contain the active ingredient mefloquine. Lariam is used to treat malaria and to help prevent you from catching malaria. Malaria is a life threatening disease and a major health risk for travellers visiting tropical countries. It occurs when small parasites are passed from one person to another by the bites of certain mosquitoes. Lariam is especially useful if you are travelling to countries where there is a type of malaria which is particularly difficult to treat. No single medicine is effective against all malaria parasites. The choice of a particular medicine depends on the sensitivity of the malaria parasites found in the area to be visited.


How to take Lariam

Take the tablets once a week, always on the same day. Take the 1st dose 10 days before you leave: this is to make sure that Lariam is well tolerated. Take the 2nd dose 3 days before you leave. Continue taking the tablets on the same day of the week throughout your stay and for 4 weeks after your return. For effective protection, you must take the complete course. Take the tablets with plenty of water, and preferably after a meal. Swallow the tablets whole, do not suck or chew them.

If you miss a dose, take it as soon as possible. If it is nearly time for your next dose, skip the missed dose and carry on as before. Do not take a double dose.

Pregnancy and breast-feeding

Pregnant women should not normally take these tablets. Due to the seriousness of malaria during pregnancy, it is recommended that you should not travel to an area where you could become infected with malaria if you are pregnant, think that you may be pregnant, or if you are planning to have a baby.

Lariam should be avoided by women who are breast-feeding. If you are pregnant or breast-feeding, think that you may be pregnant, or planning to have a baby, ask your doctor for advice before taking this medicine, as he or she may decide that you should not use this medicine.


Lariam is effective however not suitable for everyone. If you have a history of mental health issues such as psychosis, depression and anxiety then you should take another antimalarial medication depending on where you are travelling and if another option is recommended by NHS Fit For Travel.

You should not take Lariam if you have:

  • History of allergic reaction to mefloquine or chloroquine
  • Mental health problems
  • Epilepsy or a history of seizures or fits
  • Severe liver problems or impairment
  • Will be partaking in activities requiring alertness and coordination (accurate small movements) and spatial awareness (being aware of distances) such as driving, mountain climbing, piloting an aircraft, operating machinery, cycling, and deep-sea diving as Lariam can cause dizziness, loss of balance.
  • The anaesthetic halofantrine should not be used for 15 weeks after the last dose of mefloquine.

You should stop taking Lariam if you experience any of the following symptoms and change to an alternative antimalarial medication as recommended by NHS Fit For Travel:

  • depression
  • anxiety
  • suicide, attempted suicide or suicidal thoughts
  • self-endangering behaviour
  • panic attacks
  • hallucinations
