Lariam malaria tablets can help prevent malaria when travelling to countries where the risk of the disease is high. Typically malaria is found in tropical areas of the world like Africa, South America and Asia. Lariam is taken just once a week to make malaria prophylaxis simple and easy to remember. Buy Lariam from Travelpharm.

What is Lariam, and what does it do?

Lariam, also known as Mefloquine is an anti-malaria tablet that can be taken to prevent malaria infections when visiting high-risk countries. Malaria is caused by several parasites of the Plasmodium family, and mefloquine can be used to prevent an infection from one or more of these parasites.

Lariam is a popular anti-malarial for travellers going to malaria regions for extended periods. Its popularity can be attributed to the dose, just once a week, and the excellent value for money it provides.

How do I take Lariam tablets?

Lariam malaria tablets should be taken weekly as follows:

For Adults over 45kg: A single Lariam tablet is taken weekly. You start the treatment 10 days before arriving in the risk area, and then you continue whilst there and for FOUR weeks on leaving.

A typical 2 week (14 day holiday) for an adult/child over 45kg would therefore require 8 tablets. This breaks down to TWO tablets before, TWO whilst there and FOUR on return.

For Children:The amount taken WEEKLY depends on the weight of the child:

  • 5-19.9kg (3mth-5yrs): Quarter tablet
  • 20-30.9kg (6-8 yrs): Half tablet
  • 31-45kg (9-14yrs): Three quarter tablet

The frequency of dosing is the same as the adult. Start 10 days before arrival and then continue weekly, whilst there and then for four weeks on return.
