Malaria Home > Primaquine Medication Information

Primaquine is available only by prescription and is used to prevent malaria symptoms from returning (a malaria relapse). This antimalarial medication is not appropriate for everyone; your healthcare provider needs up-to-date information on your medical history and what medicines you are taking before prescribing primaquine.
While most people tolerate this drug well, primaquine can cause side effects, such as nausea, vomiting, and diarrhea. If negative reactions do occur, they tend to be minor and easily treated.
Primaquine comes in tablet form and is typically taken once a day for 14 days after leaving a malaria area. Even if you begin to feel better after taking it for a couple of days, it is important to continue taking primaquine for as long as your healthcare provider recommends.
