What you should know before starting treatment with 36-hour CIALIS for use as needed (5 mg, 10 mg, 20 mg)

You may need to take 36-hour CIALIS for use as needed more than once before you get the results you expect. But don't give up — be patient and give yourself some time. If you take CIALIS a few times and still aren't satisfied, talk with your healthcare provider. Do not take CIALIS more than one time each day.

Tell your healthcare provider about all your medical conditions and medications, and ask if your heart is healthy enough for sexual activity. Do not take CIALIS if you take nitrates such as isosorbide dinitrate or isosorbide mononitrate, which are often prescribed for chest pain, or if you use recreational drugs called "poppers," such as amyl nitrite or butyl nitrite, as this may cause an unsafe drop in blood pressure. Do not drink alcohol in excess with CIALIS. Side effects may include headache, upset stomach, delayed backache, or muscle ache. To avoid long-term injury, seek immediate medical help for an erection lasting more than 4 hours. If you have any sudden decrease or loss in hearing or vision, stop taking CIALIS and call your healthcare provider right away.
