Sildenafil Citrate (Viagra) is a prescription medicine commonly used to treat erectile dysfunction (ED) in adult men. It belongs to a group of medicines called PDE5 inhibitors and works by helping increase blood flow to the penis when a man is sexually stimulated. Sildenafil does not create sexual desire and does not cause an erection without sexual stimulation.
Sildenafil Citrate is the active ingredient in Viagra. It is used for men who have difficulty achieving or maintaining an erection suitable for sexual activity. The medicine works by supporting the body's natural erectile response. Sexual stimulation is still necessary for sildenafil to have an effect. Sildenafil is generally taken before anticipated sexual activity, according to the dosage and instructions provided by a healthcare professional. It should be used only as directed and should not be taken more frequently than prescribed.
Sildenafil Citrate is primarily used for: Treatment of erectile dysfunction (ED) in adult men Helping men achieve and maintain an erection when sexual stimulation is present Supporting normal blood flow involved in the erectile response Sildenafil is not intended to increase sexual desire, prevent sexually transmitted infections, or serve as a contraceptive.
During sexual stimulation, the body releases nitric oxide, which helps relax the muscles and increase blood flow in the penis. An enzyme called PDE5 can reduce this effect. Sildenafil inhibits PDE5, helping maintain the blood-flow response needed for an erection. In simple terms, sildenafil helps the natural erection process work more effectively when sexual stimulation occurs.
Sildenafil tablets are available in several strengths, commonly including: 25 mg 50 mg 100 mg The appropriate strength varies from person to person. A healthcare professional should determine the most suitable dose based on factors such as response, other medicines, and overall health. Do not increase the dose yourself if the medicine does not appear to be working.
Sildenafil is not suitable for everyone. Before using it, tell your doctor or pharmacist about your medical history and any medicines you take. Do not take sildenafil with nitrate medicines, including medicines commonly used for angina or chest pain. Combining these medicines can cause a dangerous drop in blood pressure. Sildenafil may also interact with certain other medicines, including some alpha-blockers and medicines that affect how sildenafil is metabolized. Seek immediate medical attention if you experience: Chest pain during or after sexual activity A sudden loss of vision A sudden loss of hearing An erection lasting more than 4 hours Common side effects can include headache, flushing, indigestion, nasal congestion, dizziness, and visual disturbances.

No. Sildenafil should not be taken with nitrate medicines because the combination can cause a potentially dangerous reduction in blood pressure.
The effect can last for several hours, although this varies between individuals. Sildenafil does not mean that an erection will last continuously during this period; sexual stimulation is still required.
