Malaria is an infection that is transmitted via mosquito bites that can cause very serious symptoms and side effects. This is a serious condition that can be contracted in several places around the world especially in parts of South and Central America, Oceania, Hispaniola, areas in the Middle East, regions in the African continent, and Southeast Asia. An antimalarial drug such as halofantrine is prescribed as a preventative measure to people traveling to those areas.
Prescription strength antimalarial drugs such as halofantrine have been known to cause serious side effects that can prevent their use except in the most extreme situations where no other alternative medicines exist. If you are administered halofantrine after contracting malaria, it is important that you remain in close contact with your medical team and follow all of their instructions. It is also likely that you may be admitted to the hospital for a substantial length of time following the contraction of malaria.
The best way to combat malarial infection is by avoiding mosquito bites in areas where the disease is a problem. Mosquitos are most active between dusk and dawn, and travelers to regions where malaria is a problem are advised to limit their time outdoors during these hours. If you must be out of doors, be sure to wear protective clothing and use an insect repellant that contains DEET. Utilize a mosquito net that has been treated with a DEET spray to protect you while you sleep. If possible, sleep with an air conditioner on and all windows closed for the highest level of protection. Utilize anti-mosquito sprays, both on yourself and to the furnishings inside your home for an added layer of protection.
In addition to treating the symptoms of malaria, the use of halofantrine may cause some unwanted side effects. Some of these effects can be harmful or be a sign of a more serious problem. If you experience any of the following symptoms, it is important that medical attention is sought right away:
There are some side effects that you might experience that will go away on their own. These symptoms are likely a reaction to the halofantrine being introduced into the system and will dissipate as the body adjusts. If these side effects do not go away on their own after a period of a few days, or if they become worse, it is best practice to confer with your prescribing physician for further medical advice. If you are concerned with the occurrence of these side effects in any way, your doctor or pharmacist can provide further insight on what to do:

Patients that are traveling to one of the known areas where malaria is a problem may be prescribed the anti-malarial drug halofantrine. This medication is an effective treatment in malaria cases and should be taken exactly as directed.
Because patients may feel a significant improvement in their symptoms after their first few doses of this medication, they are reminded that it is imperative that they complete the entire course of treatment. Cutting the course of treatment short can result in the return or worsening of the symptoms and may cause the patient to suffer for a longer period of time unnecessarily.
The best way to avoid a malaria infection is to practice a proactive approach to mosquito bite avoidance. It is recommended that insect repellants contain DEET in order to be most effective. Travelers are advised to limit the time that they spend outdoors between dusk and dawn as that is the time when mosquitos are most active. Wear protective covering when outdoors during those hours, and apply mosquito repellants when venturing out of doors.
Inform your doctor of all of the medications that you are currently taking, including both prescription and non-prescription drugs as well as any over the counter medications, prior to taking halofantrine.
