About Lariam/Mefloquine Tablets

Lariam is an effective malaria treatment and preventative. It available as a tablet and is taken once a week. Treatment begins prior to travel, continues throughout your trip and should be taken for four weeks after your return. It is important that you continue to take the tablets post-travel, to cover the disease’s incubation period.

Lariam is a branded medication manufactured by Roche and is available from our UK-based pharmacy. It contains mefloquine hydrochloride, which targets the parasite and stops it from reproducing. This product is adept at tackling the parasites present in regions where malaria has developed an immunity to other antimalarials, such as chloroquine. It also treats active malarial strains, but this needs to be done under a doctor’s supervision.

Malaria is caused by the plasmodium parasite carried by mosquitoes and is transferred to humans through bites. Symptoms can take three months to develop after infection, or even longer in some cases. These include fever, flu-like signs and headache. Some, aggressive strains may cause organ failure and death, so it is important to take precautions.

What is Lariam?

Lariam malaria tablets is a medicinal drug that is used for the prevention or chemoprophylaxis of Malaria or Malaria (disease due to a parasite transmitted by a mosquito bite). Its active component is Mefloquine, which is similar to Quinine. It is the medicine of choice recommended for certain areas of the world where other drugs to prevent malaria may be less effective as they are the parasite most resistant to them.

It can also be used as an emergency treatment when symptoms of Malaria appear such as fever, chills, and tremors if not used as prevention.

How does it work?

These anti-malarial tablets act on the asexual intraerythrocytic forms of malarial parasites that affect humans: Plasmodium falciparum, P. vivax, P. malariae, and P. ovale. It is also effective against malaria parasites that are resistant to other antimalarials (chloroquine, proguanil, pyrimethamine, and pyrimethamine combinations).

What are the benefits of taking it?

Lariam protects against and treats malaria. Malaria is transmitted through the bite of a mosquito infected with the malaria parasite. Much of the mosquitoes in the tropics are infected with this parasite. When it is infected, parasites nest in the liver. As they are adults, a part of the parasite enters the red cells destroying them. This causes fever. The parasites left in the liver can cause another attack of malaria a few weeks or months later. Lariam kills the malaria parasite and is prescribed when she goes to visit the tropics.

Concomitant administration of Lariam with other related substances (for example quinine, quinidine, chloroquine) can cause electrocardiographic abnormalities and increase the risk of seizures. It has been shown that the use of halofantrine during Lariam administration as chemoprophylaxis for Malaria treatment or 15 weeks after the last dose of Lariam considerably prolongs the QTc interval. Considering the increase in plasma concentration and the half-life of elimination of mefloquine after co-administration with ketoconazole, the risk of QTc interval prolongation may also exist if ketoconazole is taken during administration of Lariam as chemoprophylaxis or treatment of malaria or within 15 weeks after the last dose of Lariam. With mefloquine alone, no clinical prolongation has been observed. significant of the QTc interval. This appears to be the only such interaction with Lariam of clinical importance, although in theory the concomitant administration of other drugs that alter cardiac conduction could also lengthen the QTc interval.
