WARNING: Sulfadoxine/pyrimethamine has caused severe, sometimes fatal allergic reactions. These severe reactions (such as Stevens-Johnson syndrome, toxic epidermal necrolysis) usually start with a skin rash. Stop taking sulfadoxine/pyrimethamine at the first sign of a rash and seek immediate medical attention.

Sulfadoxine/pyrimethamine can cause severe bleeding, low red blood cell count (anemia), or serious infections. If you experience unusual bruising/bleeding, signs of low red blood cell count (such as severe tiredness, pale lips/nails/skin, fast heartbeat, rapid breathing at rest), or symptoms of a severe infection (such as high fever, severe chills, persistent sore throat), stop this medication and seek immediate medical attention.

USES: This medication contains 2 medicines: sulfadoxine and pyrimethamine. This combination may be used to treat malaria caused by mosquito bites in countries where malaria is common. Malaria parasites can enter the body through these mosquito bites, and then live in body tissues such as red blood cells or the liver. This medication is used to kill the malaria parasites living inside red blood cells. In some cases, you may need to take a different medication (such as primaquine) to kill the malaria parasites living in other body tissues. Both medications may be needed for a complete cure and to prevent the return of infection (relapse). Sulfadoxine/pyrimethamine belongs to a class of drugs known as antimalarials.The United States Centers for Disease Control and Prevention (CDC) does not recommend using this medication to prevent malaria (prophylaxis while traveling or living in areas where malaria is common) because severe (sometimes fatal) reactions are more common when this medication is used for prophylaxis. The CDC provides updated guidelines and travel recommendations for the prevention and treatment of malaria in different parts of the world. Discuss the most recent information with your doctor before traveling to areas where malaria occurs.This medication should not be used in infants younger than 2 months. Consult your doctor for more details.

HOW TO USE: Take this medication by mouth after a meal, as a single dose, exactly as directed by your doctor to treat malaria. Do not crush or chew the tablets. Take this drug with at least a full glass of fluid (8 ounces or 240 milliliters). Drink lots of fluids (6 to 8 glasses a day) for the next 7 to 10 days to prevent severe kidney problems (such as kidney stones).Dosage is based on your weight, medical condition, and response to treatment.If needed, primaquine can be taken for 14 days starting immediately after you have finished sulfadoxine/pyrimethamine treatment.Do not take more or less of this drug than prescribed. Doing so may cause treatment to work less well, cause the amount of parasites to increase, make the infection more difficult to treat (resistant), or worsen side effects.It is important to prevent mosquito bites (such as by using appropriate insect repellents, wearing clothes that cover most of the body, remaining in air-conditioned or well-screened areas, using mosquito nets and insect-killing sprays). Buy insect repellent before traveling. The most effective insect repellents contain diethyltoluamide (DEET). Ask your doctor or pharmacist to recommend the appropriate strengths of mosquito repellent for you/your children.No drug treatment is completely effective in preventing malaria. Seek immediate medical attention if you develop symptoms of malaria (such as fever, chills, headache, other flu-like symptoms). Malaria can return, even months after completing prevention/treatment. Quick treatment of malaria infection is needed to prevent serious, possibly fatal, outcomes.Tell your doctor if your condition persists or worsens.

SIDE EFFECTS: See also Warning section.Nausea, vomiting, or headache may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.Tell your doctor immediately if any of these unlikely but serious side effects occur: swollen/painful tongue, mental/mood changes (such as depression, hallucinations, nervousness), unusually quick sunburn (photosensitivity).Tell your doctor immediately if any of these rare but very serious side effects occur: lower abdominal/back pain, bloody/pink urine, change in amount of urine, painful urination, chest pain, irregular heartbeat, signs of severe liver problems (such as severe tiredness, persistent nausea/vomiting, yellowing skin/eyes, abdominal pain, dark urine).A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.This is not a complete list of possible side effects.
