Mefloquine Hydrochloride Information
(mef' loe kwin)Mefloquine may cause serious side effects that include nervous system changes. Tell your doctor if you have or have ever had seizures. Your doctor may tell you not to take mefloquine. If you notice any of the following symptoms while taking this medication, call your doctor immediately: dizziness, a feeling that you or things around you are moving or spinning, ringing in the ears, and loss of balance. These symptoms may occur at any time while you are taking mefloquine and can last for months to years after the medication is stopped or can be permanent. Mefloquine may cause serious mental health problems. Tell your doctor if you have or have ever had depression, anxiety, psychosis (difficulty thinking clearly, understanding reality, and communicating and behaving appropriately), schizophrenia (an illness that causes disturbed or unusual thinking, loss of interest in life, and strong or inappropriate emotions) or other mental health disorders. Also tell your doctor immediately if you develop the following symptoms while taking this medication: anxiety, feelings of mistrust towards others, hallucinations (seeing things or hearing voices that do not exist), depression, thoughts of suicide or harming yourself, restlessness, confusion, difficulty falling asleep or staying asleep, or unusual behavior. These symptoms may occur at any time while you are taking mefloquine and can last for months to years after the medication is stopped. These symptoms of nervous system changes or mental health problems may be more difficult to note in young children. Watch your child carefully and contact their doctor right away if you find any changes in behavior or health. Keep all appointments with your doctor, eye doctor, and the laboratory. Your doctor may order certain lab tests and periodic eye examinations to check your body's response to mefloquine. Talk to your doctor about the risks of taking mefloquine.
Before taking mefloquine,
- tell your doctor and pharmacist if you are allergic to mefloquine, quinidine (Quinadex), quinine (Qualaquin), any other medications, or any of the ingredients in mefloquine tablets.
- tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking.

Also tell your doctor or pharmacist if you are taking the following medications or have stopped taking them within the past 15 weeks: halofantrine (Halfan; no longer available in the United States) or ketoconazole (Nizoral).

You will have to get another medication to protect you from malaria. If no other medication is available, you will have to leave the area where malaria is common, and then get another medication to protect you from malaria.
