Sildenafil can interact with several medications. Always inform your doctor about all medications you are taking, including over-the-counter drugs and supplements.
Nitrates: Combining sildenafil with nitrates (like nitroglycerin) can cause a dangerous drop in blood pressure. This combination is strictly prohibited.
Alpha-blockers: Concurrent use with alpha-blockers (used to treat high blood pressure or enlarged prostate) may lead to significantly lower blood pressure. Your doctor may adjust your dosages or choose alternative treatments.
- Specific Alpha-blockers: Examples include terazosin, doxazosin, tamsulosin.
CYP3A4 Inhibitors: These medications can increase sildenafil levels in your body. This can heighten the risk of side effects. Examples include ketoconazole, erythromycin, and ritonavir.
CYP3A4 Inducers: Conversely, these medications can decrease sildenafil levels, potentially reducing its effectiveness. Examples include rifampin and St. John’s Wort.
Always consult your physician: Before starting or changing any medication while taking sildenafil. Provide a complete medication list: This ensures your doctor can assess potential interactions accurately. Monitor for side effects: Pay close attention to any unusual symptoms and report them immediately to your healthcare provider.
