Always inform your doctor about all medications you are taking, including over-the-counter drugs, herbal supplements, and vitamins, before starting Sildenafil Citrate 20mg. This includes nitrates, which are commonly used to treat angina (chest pain). Combining Sildenafil with nitrates can cause a dangerous drop in blood pressure.
Alpha-blockers, often prescribed for high blood pressure or enlarged prostate, can also interact with Sildenafil. This combination may lead to a significant decrease in blood pressure, potentially causing dizziness or fainting. Your doctor may adjust your dosage or recommend alternative treatments.
Interactions with Specific Medications:
Certain antifungal medications like ketoconazole and itraconazole can increase Sildenafil levels in your blood, potentially leading to side effects. Similarly, protease inhibitors, used to treat HIV, can have the same effect. Discuss these potential interactions with your physician.

| Nitrates | Nitroglycerin, isosorbide mononitrate | Severe hypotension | Avoid combination |
