What is Mefloquine?

Mefloquine is a medication used to treat and prevent malaria. Malaria is a disease that is passed on from person to person through mosquito bites. 

How does it work?

This antimalarial is able to treat and prevent malaria in areas where the disease has developed an immunity to other malaria medication. The active ingredient mefloquine hydrochloride stops the parasite from reproducing and causing further harm to the body. 

Is Mefloquine suitable for me?

Malaria is a serious health risk when travelling to some areas including South-East Asia, Africa, Central and South America, some Pacific Islands and parts of the Middle East.

Is Mefloquine safe?

Yes, Mefloquine is safe for most people. Serious side effects are rare. If you have any concerns about taking mefloquine, please talk to your doctor.

Does Mefloquine cause any damage?

Some people may experience side effects such as nausea, vomiting, diarrhoea, abdominal cramps, headache, dizziness, or insomnia. These side effects usually go away after a few days as your body adjusts to the medication.

Is this medication suited for me?

Please get in touch with a doctor if you are unsure what medication is suitable for you. You can also complete our online consultation form to check your eligibility for the product.

How is the medication delivered?

Items will usually arrive the very next day after the order has been placed. We also provide tracking for your orders to check the status and location of your parcel.

What is the Mefloquine mechanism of action?

Mefloquine works by interfering with the growth of parasites in the blood. It is effective against both erythrocytic (blood) and exoerythrocytic (liver) stages of the parasite's life cycle. Mefloquine can be used for prevention or treatment of malaria caused by Plasmodium falciparum, P. vivax, P. ovale, and P. malaria. It is also effective against chloroquine-resistant strains of P. falciparum.

How is Mefloquine used?

Mefloquine is usually taken as a single dose, once a week. It can be taken with or without food. If you vomit within 1 hour after taking mefloquine, take another dose. You should start taking mefloquine 1 to 2 weeks before you travel to an area where there is malaria. To help keep from getting malaria, take mefloquine every week during your stay and for 4 weeks after you leave the area. Mefloquine can be given for prevention of malaria starting 1 week before travel and continued for 4 weeks after leaving the risk area.

How do I order my medication?

Some products only require an online consultation which approximately takes 1 minute to complete, enabling you to then buy the product. Other products will also require a prescription; in this case, you will need to complete the online consultation, and then one of our partner pharmacy prescribers or doctors will review the online consultation questions and approve the order for delivery if you are eligible to purchase the item.

Can I cancel or return my order?

For non-medicinal products, you are eligible to return the product within 14 days of receipt in the same packaging you received. For medicinal products, you are eligible to cancel the order only until it has been dispatched. From that point forward, you are no longer eligible to return the order.
