Pravastatin belongs to the group of medicines called HMG-CoA reductase inhibitors, or statins. It works by blocking an enzyme that is needed by the body to make cholesterol, so this reduces the amount of cholesterol in the blood.

Before Using pravastatin

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 pravastatin, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to pravastatin 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

Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of pravastatin in children 8 to 18 years of age. However, safety and efficacy have not been established in children younger than 8 years of age.

Teenage girls taking pravastatin should be counseled on appropriate birth control methods to prevent pregnancy.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of pravastatin in the elderly. However, elderly patients are more likely to have age-related muscle problems, which may require caution in patients receiving pravastatin.
