Tell your doctor or health care professional as soon as possible if you do not feel well while you are taking CIALIS. CIALIS helps most people with erectile dysfunction, but it may have unwanted side effects in a few people. Most of the side effects are mild to moderate in nature. Do not be alarmed by the following list of the most common possible side effects. You may not experience any of them. Ask your doctor or health care professional to answer any questions you may have. Tell your doctor or health care professional if you notice any of the following and they are troublesome, severe, or do not go away:

• headache;
• indigestion;
• back pain;
• muscle aches;
• nasal congestion;
• facial flushing;
• swelling of the eyelids;
• eye pain;
• conjunctival hyperaemia (red eyes);
• izziness.

Allergic reactions (including skin rashes) could occur. In rare instances it is possible that a prolonged and possibly painful erection may occur after taking CIALIS. If you have such an erection which lasts continuously for more than 4 hours, you should contact a doctor immediately. In case of chest pain occurring during or after sexual activity you should NOT use nitrates but you should seek immediate medical assistance. Tell your doctor or pharmacist if you notice anything that is making you feel unwell.
