Always inform your doctor about all medications you are currently taking, including over-the-counter drugs, supplements, and herbal remedies. This is crucial for safe Sildenafil use. Certain medications can interact negatively with Sildenafil, potentially leading to adverse effects.
Nitrates: A Dangerous Combination
Combining Sildenafil with nitrates (found in medications for chest pain like nitroglycerin) can cause a dangerous drop in blood pressure. This interaction can be life-threatening. Never take Sildenafil if you are using nitrates.
Alpha-blockers: Potential for Low Blood Pressure
Alpha-blockers, often prescribed for high blood pressure or prostate problems, can also lower blood pressure. Taking Sildenafil with alpha-blockers may increase this effect, potentially causing dizziness or fainting. Your doctor might adjust your dosage accordingly.
CYP3A4 Inhibitors: Increased Sildenafil Levels
Some medications inhibit the CYP3A4 enzyme, which is responsible for breaking down Sildenafil. This means that taking Sildenafil with these inhibitors (like ketoconazole or erythromycin) can raise Sildenafil levels in your blood, increasing the risk of side effects.
Other Potential Interactions
Several other medications may interact with Sildenafil. These include:
| Antihypertensives | Losartan, Metoprolol | Increased risk of low blood pressure |
| Antibiotics | Clarithromycin, Telithromycin | Increased Sildenafil levels |
| HIV Protease Inhibitors | Ritonavir, Indinavir | Increased Sildenafil levels |
This table is not exhaustive, and individual responses can vary. Always discuss potential drug interactions with your doctor or pharmacist before starting Sildenafil.
