This medicine is a phosphodiesterase inhibitor which is used to treat erectile dysfunction (ED). After being sexual stimulated, Tadalafil tablets work by assisting the blood vessels in your penis to relax, which in turn allows blood to flow more easily into your penis. This process improves erectile function. Tadalafil (generic Cialis) will be able to assist you if you are suffering from erectile dysfunction. Cialis (tadalafil) relaxes muscles and increases blood flow to particular areas of the body.

The health and medical information provided here is for general purposes only and is not a substitute for the expertise and judgment of your physician, or other health care professional. It should not be understood to indicate that the use of this medicine is safe, appropriate or effective for you. Always consult your health care professional before using this, or any other, drug.

Do not take Cialis if you are allergic to tadalafil, or if you are also using a nitrate drug for chest pain or heart problems, including nitroglycerin (Nitrostat, Nitrolingual, Nitro-Dur, Nitro-Bid, Minitran, Deponit, Transderm-Nitro), isosorbide dinitrate (Dilatrate-SR, Isordil, Sorbitrate), and isosorbide mononitrate (Imdur, ISMO, Monoket), or recreational drugs such as amyl nitrate or nitrite ("poppers"). Taking Cialis with a nitrate can cause a serious decrease in blood pressure, leading to fainting, stroke, or heart attack.
If you become dizzy or nauseated during sexual activity, or if you have pain, numbness, or tingling in your chest, arms, neck, or jaw, stop and call your doctor right away. You could be suffering from a serious side effect of this medicine.
Do not take Cialis more than once a day. Allow 24 hours to pass between doses. Contact your doctor or seek emergency medical attention if your erection is painful or lasts longer than 4 hours. A prolonged erection (priapism) can damage the penis.
Cialis can decrease blood flow to the optic nerve of the eye, causing sudden vision loss. This has occurred in a small number of people taking Cialis, most of whom also had heart disease, diabetes, high blood pressure, high cholesterol, or certain pre-existing eye problems, and in those who smoke or are over 50 years old. It is not clear whether Cialis is the actual cause of vision loss.

Get emergency medical help if you have any of these signs of an allergic reaction to Cialis: hives; difficulty breathing; swelling of your face, lips, tongue, or throat. If you become dizzy or nauseated during sexual activity, or if you have pain, numbness, or tingling in your chest, arms, neck, or jaw, stop and call your doctor right away. You could be having a serious side effect of Cialis. Stop using this medicine and call your doctor at once if you have any of these serious side effects:
changes in vision or sudden vision loss;
ringing in your ears, or sudden hearing loss;
chest pain or heavy feeling, pain spreading to the arm or shoulder, nausea, sweating, general ill feeling;
irregular heartbeat;
shortness of breath, swelling in your hands, ankles, or feet;
seizure (convulsions);
feeling light-headed, fainting; or
penis erection that is painful or lasts 4 hours or longer.
Less serious Cialis side effects may include:
redness or warmth in your face, neck, or chest;
cold symptoms such as stuffy nose, sneezing, or sore throat;
headache;
memory problems;
diarrhea, upset stomach; or
muscle pain, back pain.

Take Cialis exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.
Cialis can be taken with or without food.
Cialis is usually taken only when needed, just before sexual activity. However, Cialis may also be taken daily (at a lower dose), regardless of when sexual activity is planned. Follow your doctor`s instructions.
Cialis can help achieve an erection when sexual stimulation occurs. An erection will not occur just by taking a pill. Follow your doctor`s instructions.
Do not take Cialis for erectile dysfunction if you are taking Adcirca for pulmonary arterial hypertension.
Do not take Cialis more than once a day. Allow 24 hours to pass between doses. If you take the medication daily, take it at the same time each day. Contact your doctor or seek emergency medical attention if your erection is painful or lasts longer than 4 hours. A prolonged erection (priapism) can damage the penis.
