Uses
CAVERTA® enables many men with ED to respond to sexual stimulation. When a man is sexually aroused, the arteries in the penis relax and widen, allowing more blood to flow into the penis.

How to Use CAVERTA
Take CAVERTA® about one hour before you plan to have sex. Beginning in about 30 minutes and lasts for up to 4 hours, CAVERTA® can help you get an erection if you are sexually excited. If you take CAVERTA® after a high-fat meal (such as fish & chips, cheeseburger or French fries), the medicine may take a little longer to start working. CAVERTA® can help you get an erection when you are sexually excited. You will not get an erection just by taking the pill.

CAVERTA SIDE EFFECTS:
Like all medicines, CAVERTA® (Sildenafil citrate) can cause some side effects. These effects are usually mild to moderate and usually don't last longer than a few hours. Some of these side effects are more likely to occur with higher doses.The most common side effects of Sildenafil citrate are headache, flushing of the face and upset stomach. Less common side effects that may occur are temporary changes in colour vision (such as trouble telling the difference between blue and green objects or having a blue colour tinge to them), eyes being more sensitive to light or blurred vision. In rare instances, men have reported an erection that lasts many hours. You should call a doctor immediately if you ever have an erection that lasts more than 4 hours. If not treated right away, permanent damage to your penis could occur.

PRECAUTIONS: What to tell your doctor before beginning Caverta®.
Only your doctor can decide if CAVERTA® is right for you. CAVERTA® can cause mild, temporary lowering of your blood pressure. You will need to have a thorough medical exam to diagnose your erectile dysfunction and to find out if you can safely take CAVERTA® alone or with your other medicines

DRUG INTERACTIONS: CAVERTA® comes in different doses (25 mg, 50 mg and 100 mg).If you do not get the results you expect, talk with your doctor. You and your doctor can determine the dose that works best for you. CAVERTA® should not be taken more than once a day. If you are older than 65 years, or have serious liver or kidney problems, your doctor may start you at the lowest dose (25 mg) of CAVERTA®. If you are taking protease inhibitors, such as for the treatment of HIV, your doctor may recommend a 25 mg dose and may limit you to a maximum single dose of 25mg of CAVERTA® in a 48-hour period.
