Always inform your doctor about all medications you take, including over-the-counter drugs, supplements, and herbal remedies, before starting Viagra or any other medication. This is especially critical in South Carolina, as medication interactions can significantly impact treatment efficacy and safety.
Certain medications increase the risk of side effects when taken with Viagra. These include nitrates (used to treat chest pain), alpha-blockers (used to treat high blood pressure and enlarged prostate), and some antifungals. Combining these could cause a dangerous drop in blood pressure.
| Nitrates | Nitroglycerin, isosorbide mononitrate | Severe hypotension (dangerously low blood pressure) |
| Alpha-blockers | Terazosin, Doxazosin, Tamsulosin | Dizziness, fainting |
| CYP3A4 Inhibitors | Ketoconazole, Erythromycin, Ritonavir | Increased Viagra levels, potentially leading to heightened side effects |
| CYP3A4 Inducers | Rifampin, St. John’s Wort | Decreased Viagra levels, reducing effectiveness |
Grapefruit juice inhibits the metabolism of Viagra, leading to higher blood levels and increased risk of side effects. Avoid grapefruit and grapefruit juice while taking Viagra.
