Always inform your doctor about all medications you’re taking, including over-the-counter drugs, herbal supplements, and recreational drugs. This includes nitrates, commonly found in medications for chest pain. Combining Cialis with nitrates can cause a dangerous drop in blood pressure.
Certain medications can affect how Cialis works. These include:
- Alpha-blockers: Used to treat high blood pressure or enlarged prostate. Combining them with Cialis may significantly lower blood pressure. CYP3A4 inhibitors: These medications, such as ketoconazole and ritonavir, can increase Cialis levels in your blood, potentially increasing side effects. CYP3A4 inducers: Drugs like rifampin can decrease Cialis effectiveness.
Grapefruit juice can also interact with Cialis. Avoid consuming it while taking this medication.
Cialis can affect your blood pressure and may cause dizziness or fainting. Avoid activities requiring alertness after taking the medication, especially until you know how it affects you.
If you have heart problems, a recent heart attack or stroke, low blood pressure, or uncontrolled high blood pressure, talk to your doctor before starting Cialis. The same applies if you have liver or kidney disease.
Sudden vision loss: Stop taking Cialis and seek immediate medical attention if you experience sudden vision loss in one or both eyes. Hearing loss: Report any sudden hearing loss or ringing in your ears to your doctor immediately. Prolonged erection (priapism): Seek immediate medical help if you have an erection lasting more than four hours.
Always follow your doctor’s instructions regarding dosage and frequency. Never exceed the prescribed dose.
