Combining Viagra (sildenafil) with certain blood pressure medications can lower blood pressure significantly, potentially leading to dizziness, fainting, or even more serious complications. This risk is most pronounced with nitrates, often prescribed for angina (chest pain).
Avoid combining Viagra with nitrates. This includes nitroglycerin, isosorbide dinitrate, and isosorbide mononitrate, in any form (tablets, patches, sprays). The interaction can cause a dangerous drop in blood pressure.
Alpha-blockers, such as terazosin and doxazosin, also increase the risk of low blood pressure when taken with Viagra. Your doctor should carefully monitor your blood pressure if you’re taking both medications. They might adjust your dosages or suggest alternative treatments.
Other blood pressure medications, like ACE inhibitors, ARBs, and beta-blockers, may also interact with Viagra, albeit usually less dramatically. Open communication with your doctor about all medications you take is vital. They can assess the potential risks and guide you toward the safest approach.
Always inform your doctor about all prescription and over-the-counter medications, supplements, and herbal remedies before starting Viagra. This includes any medications for high blood pressure, heart conditions, or other health issues. Your doctor will help you manage potential interactions and ensure your safety.
