Fildena 100 mg, containing sildenafil citrate, is an effective treatment for erectile dysfunction in men. It works by enhancing blood flow to the penis, allowing for the achievement and maintenance of an erection in response to sexual stimulation. To ensure safety and effectiveness, it is important to follow the prescribed dosage and consult a healthcare provider if you have any underlying medical conditions or are taking other medications. Avoid taking more than one dose per day, and seek medical help if you experience any serious side effects, such as priapism or sudden vision loss.

Fildena 100 mg may interact with other medications, which can either increase the risk of side effects or reduce the effectiveness of sildenafil. If you have heart disease, a history of heart attack, stroke, or arrhythmia, you should be cautious with sildenafil. The medication can affect blood pressure, and sexual activity itself can put strain on the heart. Seek immediate medical help if you experience these symptoms during sexual activity.

Sildenafil citrate works by blocking the enzyme PDE-5 inhibitors, which is responsible for breaking down cyclic GMP. By inhibiting this enzyme, sildenafil helps to increase the levels of cyclic GMP, resulting in relaxed blood vessels and increased blood flow to the penis, making it easier to achieve and sustain an erection during sexual activity. It's important to note that sexual arousal is still required for the drug to work; it does not induce an erection without stimulation.
