Malarone 250mg/100mg tablets


Malarone is a prescription medication used to prevent and treat malaria. Malaria is a serious and potentially life-threatening disease that is spread by the bite of infected mosquitoes.

Malarone contains a combination of two active ingredients, atovaquone, and proguanil, that work together to kill the malaria parasites in your blood. It is most effective when taken before, during, and after exposure to the disease, and is considered one of the most effective antimalarial medications available.

This medication is well-tolerated by most people, and its side effects are generally mild and short-lived. Common side effects may include nausea, headache, and abdominal pain. If you experience any severe or persistent side effects, you should seek medical attention immediately.

If you are traveling to an area where malaria is common, talk to your doctor about whether Malarone is right for you. This medication can provide peace of mind and protection against a serious and potentially life-threatening disease. 


Before embarking on your malaria-exposed journey, it is imperative to internalize the ensuing instructions. Malarone serves a dual purpose: the prevention and treatment of malaria. Depending on your specific objective, adhere scrupulously to the prescribed dosing regimen.


The efficacy of Malarone emanates from its synergistic active constituents—namely, atovaquone and proguanil hydrochloride. These agents are encased within the tablet's core, a blend of poloxamer 188, microcrystalline cellulose, hydroxypropyl cellulose, povidone K30, sodium starch glycollate (Type A), and magnesium stearate. Enveloping this core is a coating comprising hypromellose, titanium dioxide (E171), iron oxide red (E172), macrogol 400, and polyethylene glycol 8000, which facilitates optimal delivery.

Side effects

While Malarone undoubtedly stands as a stalwart guardian against malaria, it is pertinent to acknowledge the potential for side effects. These can span a spectrum from mild to severe. Vigilance is essential to detect signs of severe allergic reactions, skin aberrations, gastrointestinal disturbances, and other sporadic symptoms. In the event of such manifestations, immediate consultation with a healthcare professional is paramount.


Prioritizing your safety is non-negotiable. Refrain from using Malarone if allergies to its constituents are evident or if severe renal impairment exists. Prudent consideration is warranted for those with the aforementioned conditions or if the weight of a child is below 11 kg. Equally significant is understanding potential interactions with concurrent medications. For expectant or nursing individuals, soliciting expert medical advice is indispensable before embarking on Malarone.
