Interactions with Other Medications

Always inform your doctor about all medications you are taking, including over-the-counter drugs, herbal supplements, and recreational drugs. This includes nitrates, often prescribed for chest pain. Combining Cialis with nitrates can cause a dangerous drop in blood pressure.

Alpha-Blockers and Cialis

Alpha-blockers, used to treat high blood pressure or an enlarged prostate, can interact with Cialis, potentially leading to low blood pressure. Your doctor should carefully monitor your blood pressure if you are taking both.

Other Medications Requiring Caution

Certain antifungal medications, HIV protease inhibitors, and some antibiotics may influence Cialis’s metabolism. This can affect its effectiveness or increase the risk of side effects. Discuss any potential interactions with your physician before starting or changing any medication regimen. Always consult your doctor or pharmacist before making any changes to your medication.

Grapefruit Juice and Cialis

Avoid grapefruit juice while taking Cialis. Grapefruit can alter the way your body processes Cialis, potentially leading to higher concentrations in your bloodstream and increased side effects. This interaction is significant and should be avoided.
