Can I take Diovan if I'm allergic to sulfa drugs?

Stacy Wiegman, PharmD
Pharmacy Specialist

If you are allergic to sulfa drugs, talk to your doctor before taking Diovan (valsartan), a drug prescribed for high blood pressure and heart failure, and to prolong life after a heart attack. Having an allergy to any medicine raises your risk for other drug allergies. The risk of an allergy may be even higher if you are taking a formulation called Diovan HCT, which includes a diuretic medicine called hydrochlorothiazide. People who have allergies to sulfa drugs may be at an especially high risk for allergies to hydrochlorothiazide.

Before taking Diovan, give your doctor a detailed medical history that includes your history of allergic reactions. Call your doctor or 911 immediately if you experience any symptoms that might be due to allergic reaction, including itching or hives, chest tightness, trouble breathing, or swelling in your hands, face, mouth or throat.

Diovan may be taken by someone with sulfa allergy. Although rare, it is important to note that people may have an allergic reaction to their medication regardless of having a sulfa allergy. If you ever experience itching, rash or difficulty breathing when starting a new medication, follow up with your doctor as soon as possible.
