About Lariam

Lariam is a prescription-only, antimalarial medication used in the treatment and prevention of malaria. It contains the active ingredient mefloquine, a suppressive antibiotic which cures malaria once the infection is in the bloodstream.

Malaria can be life-threatening and is prevalent in many tropical and subtropical countries. It is a parasitic infection passed on by the bite from a mosquito with the disease, though the mosquito itself can only be infected by biting a human who already has malaria. As such, using a prevention medication before you travel is not just beneficial for your health but a positive way to help stop the spread of malaria.

The information provided in the summary table is for reference only. It is important to consult a qualified healthcare professional before starting any Anti Malarial treatment, including Lariam.

How effective is Lariam?

Lariam is effective at treating and preventing mild to moderate malaria. The medication is commonly used in areas where there is a hard-to-treat form of malaria or when other medications may not be effective.

Malaria transmission is highest in West Africa, where the parasites are resistant to the drug chloroquine, and yet they are sensitive to Lariam. As such, Larium is often prescribed for anyone travelling to these types of high-risk area.

Due to this ineffectiveness of some forms of antimalarial tablet, it is important to discuss which treatment is right for your particular trip and the country you are travelling to.

What are the advantages of taking Lariam?

Aside from its attractive lower cost, one great advantage of choosing Lariam over other anti-malaria drugs is that it only needs to be taken once a week rather than every day. For a traveller who has a lot on their mind in the lead up to their trip, this could be a safer way to take this necessary drug as, if you miss one of the daily drugs, you may not be properly covered for your time away in a high-risk area.

It is also considered safe for pregnant women and children to take, but this should be discussed with your doctor at Click Pharmacy before deciding to go ahead with Lariam whilst pregnant.

How does Lariam work?

The parasites which cause malaria are known as Plasmodium, which is injected by the bite of an infected mosquito. The parasites then go onto reproduce and eventually, if left without prevention or treatment, result in the disease Malaria.

Lariam contains a drug called Mefloquine which attacks the Plasmodium within the red blood cells, thus preventing them from further developing.

Although effective at fighting against the malarial parasites, the treatment does not prevent you from being bitten by a mosquito in the first place, as such it is important to use other forms of prevention such as keeping your skin covered, wearing a high percentage DEET repellent and using a mosquito net at night and over the doors and windows of your accommodation.

Alternatives to Lariam

In some cases, Lariam does not work. Not only that, but the choice of antimalarial comes down to personal preference and suitability. Due to this, you can find various antimalarial medications available over the counter and on prescription in the UK. Before choosing an alternative, it is crucial to consult your GP or pharmacist, as they will let you know of the benefits and risks associated with each treatment. Alternatives to Lariam include:

  • Doxycycline
  • Malarone

What dose should I choose?

It is important that you take the exact dose that has been prescribed to you. For adults, this is usually one tablet each week starting 1 week before you travel to a high-risk area. If you already take other medications, it is advisable to start taking Lariam 2 or 3 weeks prior to travel to ensure that the combination of drugs is tolerable. The medication should then be continued throughout your trip on the same day each week and then for a further 4 weeks upon your return home.

For more information on dosages, you can read the patient information leaflet that comes with your medication and discuss it with your GP prior to getting your prescription.

How should I take Lariam?

Take one tablet with plenty of water right after you finish your main meal of the day, as the medication should not be taken on an empty stomach. If the tablet cannot be swallowed whole, it may be crushed or mixed in water, but make sure that you receive the whole dose.

If you vomit less than 30 minutes after taking the drug, it may be advised that you take a secondary full dose. If vomiting occurs between 30 minutes and one hour after taking the tablet, a half dose may be recommended.

For more information on dosages in case of vomiting, you can also ask your GP or our experts at Click Pharmacy for additional guidance.

Side effects

Similar to all medicines, you are likely to experience different side effects from using Lariam Tablets. Common side effects can include the following:

  • Headaches
  • Drowsiness
  • Feeling dizzy
  • Insomnia (struggle to sleep)
  • Aches and pains around the body
  • Fainting
  • Temperature

The active ingredient in Lariam Tablets, mefloquine, has links to psychiatric conditions such as panic attacks and depression. If you suffer from mental health problems you are likely to experience more severe side effects. It is advised to not use this product if you suffer from mental health problems as the side effects have life threatening potential.

Can I crush Lariam Tablets if I struggle to swallow?

It is safe to crush Lariam Tablets and combine with water if you struggle to swallow one whole capsule.
