What is the relationship between erectile dysfunction and Cialis (Tadalafil)?

From the Guidelines

Cialis (tadalafil) is an effective medication for treating erectile dysfunction (ED), with a recommended starting dose of 10 mg taken orally before sexual activity, which can be increased to 20 mg if needed, as supported by the American Urological Association guideline 1.

Key Points

• Cialis works by increasing blood flow to the penis, helping to achieve and maintain an erection, as a PDE5 inhibitor that relaxes smooth muscles in blood vessel walls.
• The dose of Cialis should be titrated to provide optimal efficacy, with a daily dose of 2.5 to 5 mg available for continuous ED treatment.
• Important considerations include:
  • Taking Cialis 30 minutes to 2 hours before sexual activity
  • Not exceeding one dose per day
  • Taking daily doses at the same time each day
  • Avoiding grapefruit juice due to potential increased side effects
  • Not using Cialis with nitrates (e.g., nitroglycerin) due to risk of severe hypotension
  • Common side effects including headache, back pain, and indigestion

Recommendations

• Consult a healthcare provider before starting Cialis, especially if you have heart problems, low blood pressure, or are taking other medications, as recommended by the American College of Physicians 1.
• Men with ED should be informed about the treatment option of an FDA-approved oral phosphodiesterase type 5 inhibitor (PDE5i), including discussion of benefits and risks/burdens, unless contraindicated, as stated in the AUA guideline 1.
• The choice of a specific PDE-5 inhibitor should be based on individual preferences, including ease of use, cost of medication, and adverse effects profile, as recommended by the American College of Physicians 1.
