Cialis - (Tadalafil)

If you have any of these other conditions, you may need a Cialis dose adjustment or special tests:

• heart disease or heart rhythm problems;
• a recent heart attack (within the past 90 days);
• a recent history (in the past 6 months) of a stroke, or congestive heart failure;
• angina (chest pain), high or low blood pressure;
• liver disease;
• kidney disease (or if you are on dialysis);
• a blood cell disorder such as sickle cell anaemia, multiple myeloma, or leukemia;
• a bleeding disorder such as hemophilia;
• a stomach ulcer;
• retinitis pigmentosa (an inherited condition of the eye);
• a physical deformity of the penis (such as Peyronie's disease); or
• if you have been told you should not have sexual intercourse for health reasons.

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. Stop using Cialis and get emergency medical help if you have sudden vision loss.

How to take Cialis

Before starting this treatment, read the manufacturer's printed information leaflet from inside the pack. Take cialis exactly as your doctor has told you.
It is not important whether you take cialis before, with or after food.

If you have been prescribed cialis for erectile dysfunction:

• Take your medicine at least 30 minutes before sexual activity.
• Cialis should not be taken more frequently than once a day.

If you have been prescribed cialis for pulmonary arterial hypertension:

• Try to take cialis at the same time each day to avoid missing any doses.
• If you forget to take a dose, take it as soon as you remember unless it is nearly time for your next dose, in which case leave out the missed dose. Do not take two doses together to make up for a missed dose.

How should I take Cialis?

• 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. Do not break or split a Cialis tablet. Swallow it whole.
• Cialis is usually taken only once per day. Follow your doctor's instructions. For erectile dysfunction, take the medicine just before sexual activity but not more than once per day.
• 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.

What should I avoid while taking Cialis?

• Drinking alcohol can increase certain side effects of Cialis.
• Grapefruit and grapefruit juice may interact with Cialis and lead to potentially dangerous effects. Discuss the use of grapefruit products with your doctor.
• Avoid using other medicines to treat erectile dysfunction, such as sildenafil (Viagra) or vardenafil (Levitra) while you are taking Cialis.

Cialis side effects

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 or feet;
• seizure (convulsions);
• feeling light-headed, fainting; or

Less serious Cialis side effects may include:

• redness or warmth in your face, neck, or chest;
