Viagra, containing sildenafil, lowers blood pressure. Combining it with pre-existing low blood pressure can cause a significant drop, potentially leading to dizziness, fainting, or even a heart attack. This risk is amplified in individuals already taking other blood pressure medications.
Specifically, sildenafil inhibits PDE5, an enzyme that regulates blood vessel dilation. This dilation, while beneficial for erectile dysfunction, can exacerbate hypotension. A study in the American Journal of Cardiology showed a correlation between sildenafil use and increased risk of cardiovascular events in patients with pre-existing hypertension, suggesting a similar risk, potentially heightened, for individuals with low blood pressure.
Before taking Viagra, individuals with low blood pressure should consult their physician. A thorough medical history review and potential adjustments to medication are necessary. Your doctor can assess your overall health, including any other medications you are taking, to determine the safest course of action. They might suggest alternative treatments for erectile dysfunction or recommend careful monitoring of your blood pressure while on sildenafil.
Monitoring blood pressure regularly after starting Viagra, especially in the initial stages, is highly recommended. Report any unusual symptoms such as chest pain, severe dizziness, or shortness of breath to your doctor immediately. Open communication with your healthcare provider is key to managing this potential interaction safely.
