Medications like Caverta helps men come out of such situations by enabling that erection happens. Its main composition is a chemical called Sildenafil Citrate that broadens the arteries and enables blood flow into them. This increases the flow of blood into the penis. Erectile dysfunction happens due this lack of blood circulation. With more and more blood flowing in and less and less blood flowing out; the erection of penis becomes easier and lasts for a longer time. Caverta however is not a hormone or aphrodisiac, it works only when a man is sexually stimulated otherwise not.

It is best to consume Caverta about one hour before the sexual encounter. The action mechanism of Caverta is quite impressive as the effect of Caverta begins within 30 minutes of its intake and lasts up to 4 hours. Cavetra helps in erection only if the man is sexually excited, hence foreplay or sexual overtures helps a lot. Erection will not take place just by merely taking the pill. If Caverta is taken after a heavy meal such as fish, cheeseburger, etc. the working time for it might get delayed a bit.

Caverta can cause some side effects like many other medicines. However these happen only when the medicine is taken in high doses and can be over come by taking it on a moderate level. The most common side effects of Caverta include headache, dizziness, nasal congestion, indigestion, etc.
