Interactions with Other Medications and Substances

Always inform your doctor about all medications, supplements, and recreational drugs you use before taking Cialis. This includes over-the-counter medications like ibuprofen or aspirin. Some medications, particularly nitrates used to treat chest pain, can interact dangerously with Cialis, causing a significant drop in blood pressure. This combination can be life-threatening.

Specific Medication Interactions

Alpha-blockers, often prescribed for high blood pressure or enlarged prostate, can also lower blood pressure when combined with Cialis. This interaction might lead to dizziness or fainting. Similarly, certain antifungals, such as ketoconazole and itraconazole, can increase Cialis levels in your blood, potentially intensifying side effects. Grapefruit juice contains compounds that affect the metabolism of many medications, including Cialis; avoid it while taking Cialis to prevent unexpected side effects.

Substances to Avoid

Combining Cialis with alcohol can increase the risk of side effects like dizziness, headache, and low blood pressure. Also, avoid using recreational drugs, especially those that affect your heart or blood pressure. These substances can compound the effects of Cialis, posing significant health risks. Always consult your physician to understand potential interactions and ensure safe medication use.
