Brand Hydrazide 25 mg

Hydrazide contains 2 drugs (hydralazine and hydrochlorothiazide). Generally, it should not be used when treating high blood pressure for the first time. Your doctor should first give you each of the drugs separately to find the best dose of each drug for you. Use this combination product only if your doctor has decided that the doses of each drug in this product are right for your condition. Your doctor may need to continually adjust your medications depending on your condition.

Cholestyramine and colestipol can decrease the absorption of this medication. If you are taking either of these drugs, take them at least 4 hours apart from this medication.
