Cialis (tadalafil) is the only medication in its class that treats both erectile dysfunction and enlarged prostate symptoms. You can also take it on a regular basis, which can allow for more spontaneity.
If you are between the ages of 18 and 60, take no other medication or have no other medical conditions, side effects you are more likely to experience include:
- A headache, dyspepsia, back pain, nasal congestion, and flushing are the most commonly reported side effects.
- Other side effects include a drop in blood pressure, muscle or limb pain, or conjunctivitis.
- Rarely, may decrease blood flow to the optic nerve causing sudden vision loss. The risk is greater in people aged older than 50, with diabetes, heart disease, high blood pressure, high cholesterol, who smoke, or with certain pre-existing eye problems.
- The dosage of Cialis may need reducing in men with kidney disease. For men with CLCR of 30 to 50 mL/min, a starting dose of 5mg not more than once per day is recommended. The maximum dose is 10mg not more than once every 48 hours.
- For men with CLCR of < 30 mL/min or on hemodialysis, the maximum dose is 5mg not more than once every 72 hours. Once daily use may not be recommended in men with CLCR < 30 mL/min.
- For men with mild-to-moderate liver disease (Child-Pugh Class A or B), the dose should not exceed 10mg once per day. Cialis is not recommended in severe liver disease (Child-Pugh Class C).
- Rarely, may cause other side effects including hearing loss or lead to painful erections lasting longer than four to six hours. See your doctor immediately if this happens.
- May not be suitable for some people including those with angina, chest pain, or other heart conditions, liver or kidney problems, blood or bleeding disorders, stomach ulcers, certain eye conditions, a physical deformity of the penis (such as Peyronie’s disease), or serious prior hypersensitivity reactions to tadalafil.
- May interact with some medications including nitrates – use of Cialis and nitrates is contraindicated because of the severe hypotension that can develop. May also interact with other medications including ketoconazole or ritonavir; dosage adjustment is recommended.
- A lower dosage of Cialis is recommended in men with mild-to-moderate liver disease. Cialis should be avoided with severe liver disease.
- Not for use in females.
