Always inform your doctor about all medications you’re taking, including over-the-counter drugs and supplements, before starting Cialis 20mg. Certain medications can interact negatively with Cialis, potentially causing harmful side effects or reducing its effectiveness.
Nitrates: Avoid nitrates (found in medications for chest pain like nitroglycerin) completely. Combining them with Cialis can drastically lower blood pressure, leading to a dangerous drop.
Alpha-blockers: These medications, often used for high blood pressure or enlarged prostate, can cause a significant drop in blood pressure when taken with Cialis. Your doctor might adjust your dosage or suggest alternatives.
Guanylate cyclase stimulators: These drugs treat pulmonary hypertension and should not be used with Cialis due to the risk of severe hypotension.
CYP3A4 inhibitors: Some medications inhibit the CYP3A4 enzyme, which metabolizes Cialis. This can increase Cialis levels in your blood, potentially intensifying side effects. Examples include ketoconazole and ritonavir. Your doctor may need to lower your Cialis dose.
Other medications: Several other medications may interact with Cialis, so complete transparency with your physician is paramount. This includes antifungal medications, antibiotics, and certain HIV medications. Your doctor can assess the potential risks and make informed decisions about your treatment.
Grapefruit Juice: Avoid grapefruit juice while taking Cialis. It contains compounds that inhibit CYP3A4, similar to some medications, increasing the risk of side effects.
