Caverta is designed to aid you in your metabolic and physical issues. It can help men who have erectile dysfunction get and sustain an erection when they are sexually excited. The main component of Caverta is Sildenafil, which affects the response to sexual stimulation. It acts by enhancing smooth muscle relaxation using nitric oxide, a chemical that is normally released in response to sexual stimulation. This smooth muscle relaxation allows increased blood flow into certain areas of the penis, which leads to an erection. Sildenafil is applied for the treatment of erectile dysfunction (impotence) in men and pulmonary arterial hypertension. 

You should take the tablets through only the oral route with water. Ideally the medicine will take 30-50 minutes to reach the desired area of body as it dissolves in blood. It is always preferred to talk to doctor if you experience any side effects after consumption of this medicine or have chosen as self medication.

Caverta Sildenafil 100mg works when you take it almost an hour prior to the plans of becoming sexually active. The effects last for 4 hours and it begins its activity in a 30 minute period. The potential of this medication could go down as you consume meals high in fat, fried items or fast food. It is possible there can be mixed drug interactions if you take it with similar prescription medication to treat erectile dysfunction.

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.

Caverta is contraindicated in patients taking another medicine to treat impotence or using a nitrate drug for chest pain or heart problems. 
This medicine should not be taken by women and children as well as in patients with a known hypersensitivity to any component of the tablet.
