Consult your doctor before using Cialis 20mg, especially if you have heart problems, low blood pressure, or have experienced a stroke or heart attack. This medication can interact negatively with nitrates, commonly used to treat angina. Avoid combining them.
Heart Conditions and Blood Pressure
Cialis can lower blood pressure. If you have unstable angina, severe heart failure, or uncontrolled hypertension, Cialis may not be suitable for you. Inform your physician of all your health conditions before starting treatment.
Other Medications
Certain medications can interact with Cialis, potentially leading to adverse effects. Examples include alpha-blockers (used for prostate problems) and antifungal medications like ketoconazole. Always provide a complete list of your current medications to your doctor.
Specific Considerations
Men with kidney or liver problems should discuss appropriate dosage with their doctor. Cialis may be less effective or cause increased side effects in these cases. Individuals with a history of priapism (prolonged erection) should avoid Cialis due to the increased risk of this condition.
Vision Changes
Rarely, Cialis can cause sudden vision loss or hearing loss. Seek immediate medical attention if you experience these symptoms.
