Always follow your doctor’s instructions precisely. The standard starting dose of Cialis is 10mg taken as needed, at least 30 minutes before sexual activity.
Dosage Adjustments
Your doctor may adjust your dose based on your response and individual needs. A lower dose of 5mg may be prescribed, or a higher dose of 20mg might be considered. Never exceed the maximum recommended dose without consulting your physician.
Administration
Take Cialis orally with or without food. The absorption of Cialis can be affected by fatty foods, potentially delaying onset of action. Avoid grapefruit and grapefruit juice, as they can interact with Cialis and lead to increased blood levels of the medication. Drink plenty of water with your dose.
Frequency of Use
Cialis is available in two primary formulations: as-needed and daily. The as-needed formulation is taken only when required for sexual activity. The daily formulation allows for spontaneity, but requires consistent daily use. Discuss the best option for your lifestyle with your doctor.
Missed Dose
If you miss a dose of the daily formulation, take it as soon as you remember, unless it is almost time for your next dose. Do not double the dose. For the as-needed formulation, simply take it when needed prior to sexual activity.
