Cenforce 200 mg contains sildenafil citrate, a phosphodiesterase type 5 (PDE5) inhibitor used for erectile dysfunction. While effective, it can interact negatively with several medications, potentially causing serious side effects.

The most critical interactions occur with nitrate medications, commonly prescribed for chest pain or angina (e.g., nitroglycerin, isosorbide mononitrate). Combining sildenafil with nitrates can cause a dangerous drop in blood pressure, leading to dizziness, fainting, heart attack, or stroke.

Alpha-blockers, used for high blood pressure or prostate problems (e.g., tamsulosin, doxazosin), can also interact, potentially causing symptomatic hypotension—especially when first starting sildenafil.

Certain antifungal medications (like ketoconazole or itraconazole) and HIV protease inhibitors (such as ritonavir) can increase sildenafil levels in the blood, raising the risk of side effects including headache, flushing, vision changes, or prolonged erections.

Other interactions may occur with blood pressure medications, some antibiotics, and herbal supplements like ginseng or garlic, which may influence blood flow or drug metabolism.

To minimize risk, men should inform their doctor of all medications and supplements before taking Cenforce 200 mg. Dosage adjustments or alternative treatments may be necessary. Regular monitoring is recommended for men with cardiovascular disease, liver/kidney issues, or other chronic conditions.

In summary, nitrates, alpha-blockers, certain antifungals, HIV medications, and some blood pressure drugs are the main medications that can interact negatively with Cenforce 200 mg.
