That depends on how high your blood pressure is.
For example, if you have high blood pressure that’s not controlled, your heart may not be healthy enough for sexual activity. (With uncontrolled high blood pressure, your blood pressure is greater than 170/110 mmHg.) If this is the case, talk with your doctor about whether Viagra is safe for you.
However, if you have high blood pressure that’s controlled with medication and you also don’t have a heart condition, it’s usually fine to take Viagra. Just be aware that taking the drug could lower your blood pressure.
Low blood pressure from Viagra usually isn’t a problem for most people. But if you’re taking a type of blood pressure drug called an alpha-blocker, taking Viagra might cause certain side effects. These side effects can include dizziness, lightheadedness, or even fainting. For more information about using Viagra with alpha-blockers, see the “Viagra interactions” section below.
If you have high blood pressure that’s controlled with medication, your doctor may prescribe a dose of Viagra for you that’s lower than the typical dose.
Before starting Viagra, talk with your doctor about any blood pressure problems you have.
