Always consult your doctor before using Viagra, especially if you have pre-existing health conditions. Viagra’s interaction with other medications and health issues can be significant.
Heart Conditions
Viagra can lower blood pressure. If you have heart disease, high blood pressure, or have recently had a heart attack or stroke, Viagra may pose risks. Your doctor will assess your suitability carefully.
Eye Conditions
Certain rare eye conditions, like Non-arteritic anterior ischemic optic neuropathy (NAION), have been linked to Viagra use. Discuss any vision problems with your doctor before starting treatment. This is particularly crucial if you have a history of such issues.
Liver or Kidney Disease
Your doctor needs to know about any liver or kidney problems. These organs process medications, and impairment can affect how Viagra is metabolized, potentially increasing side effects.
Blood Cell Disorders
Individuals with sickle cell anemia, leukemia, or multiple myeloma should exercise caution. Viagra can affect blood cell function, and these conditions may increase the risks of complications.
Other Medications
Viagra interacts with many medications, including nitrates (often used for chest pain), alpha-blockers (used for high blood pressure and prostate issues), and some antifungals. Providing your doctor with a complete medication list is vital for safe usage.
