Interactions with Other Medications and Substances

Always inform your doctor about all medications you’re taking, including over-the-counter drugs, herbal remedies, and recreational drugs. This includes nitrates, which can cause a dangerous drop in blood pressure when combined with Cialis. Combining Cialis with nitrates is strictly prohibited.

Alpha-blockers, often prescribed for high blood pressure or enlarged prostate, can interact with Cialis, potentially leading to dizziness or fainting. Your doctor may need to adjust your dosage or choose alternative medications.

Some antifungals, like ketoconazole and itraconazole, can increase Cialis levels in your blood, potentially intensifying side effects. Your doctor might suggest a lower Cialis dose or a different antifungal medication.

Grapefruit juice inhibits the enzymes that break down Cialis, increasing its concentration in your bloodstream. Avoid grapefruit juice while taking Cialis to prevent unwanted side effects.

Alcohol can worsen Cialis side effects, such as dizziness and headaches. Moderate your alcohol consumption while using this medication.
