Before Using

Drug information provided by: Merative, Micromedex®

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Although there is no specific information comparing use of this medicine in children with use in other age groups, this medicine is not expected to cause different side effects or problems in children than it does in adults.

Geriatric

Many medicines have not been studied specifically in older people. Therefore, it may not be known whether they work exactly the same way they do in younger adults. Although there is no specific information comparing use of reserpine, hydralazine, and hydrochlorothiazide combination in the elderly with use in other age groups, this medicine is not expected to cause different side effects or problems in older people than it does in younger adults. However, drowsiness, dizziness, or faintness, or symptoms of too much potassium loss may be more likely to occur in the elderly, who are usually more sensitive to the effects of this medicine. Also, this medicine may reduce tolerance to cold temperatures in elderly patients.

Breastfeeding

Hydralazine

Studies in women suggest that this medication poses minimal risk to the infant when used during breastfeeding.

Reserpine

Hydrochlorothiazide

There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.
