Suhagra 50 mg contains sildenafil, which is a phosphodiesterase type 5 (PDE5) inhibitor used to treat erectile dysfunction. It's important to be aware of potential drug interactions, as combining sildenafil with certain medications can lead to adverse effects or changes in the way the drugs work. Here are some potential drug interactions with Suhagra 50 mg:

Nitrates: Concomitant use of sildenafil with nitrates (such as nitroglycerin) or other drugs that release nitric oxide (NO) is contraindicated. The combination can lead to a dangerous drop in blood pressure, which can be life-threatening.

Alpha-Blockers: Combining sildenafil with alpha-blockers (medications used to treat high blood pressure or prostate conditions) can also result in a significant decrease in blood pressure. Caution is advised, and dosage adjustments may be necessary.

Antihypertensive Medications: Sildenafil can potentiate the hypotensive (blood pressure-lowering) effects of some antihypertensive medications. It's important to inform your healthcare provider of all medications you are taking for high blood pressure.

HIV Protease Inhibitors: Some medications used to treat HIV, particularly protease inhibitors, can increase the levels of sildenafil in the blood. This may increase the risk of sildenafil-related side effects.

Antifungal Medications: Azole antifungals, such as ketoconazole or itraconazole, can increase the levels of sildenafil in the blood. Dose adjustments may be necessary.

Macrolide Antibiotics: Some macrolide antibiotics, like erythromycin, can also increase sildenafil levels. The combination should be used with caution, and dosage adjustments may be needed.

Riociguat: The concurrent use of sildenafil with riociguat, a medication used to treat pulmonary arterial hypertension, is contraindicated due to the risk of hypotension.

It's crucial to inform your healthcare provider about all medications you are taking, including prescription and over-the-counter drugs, as well as any herbal supplements. This information will help your healthcare provider assess the risk of potential drug interactions and make appropriate recommendations.

This list is not exhaustive, and individual responses to medications can vary. Always follow the guidance of your healthcare provider and pharmacist, and do not self-adjust or combine medications without consulting a healthcare professional.
