Viagra Precautions

Before using Viagra, tell your doctor your medical history, including allergies (especially drug allergies), penis conditions such as fibrosis/scarring (e.g., Peyronie's disease), history of painful/prolonged erection (priapism), sickle cell anemia, blood system cancers (such as leukemia or myeloma), eye problems (retina diseases), kidney or liver disease, bleeding disorders, active stomach ulcers, heart disease, stroke or very high or low blood pressure. Limit alcohol intake, as it may aggravate side effects of this drug. Since Viagra may cause dizziness, caution is advised when performing tasks requiring alertness (e.g., driving). To avoid dizziness and lightheadedness when rising from a seated or lying position, get up slowly. Viagra is not to be used in women or children. The elderly may be more sensitive to the side effects of this drug, therefore caution is advised in this group.
