Description:Sildenafil is used to treat erectile dysfunction (ED) in men. It is a member of the class of drugs known as phosphodiesterase type 5 (PDE5) inhibitors. Sildenafil works by relaxing the blood vessels in the penis, allowing blood to flow in when sexually stimulated. This allows for increased blood flow and an improved ability to achieve and maintain an erection.

Prescription:Sildenafil is available in several branded and generic forms, including tablets, capsules, and oral suspension. It is typically taken as needed, about 30 minutes before sexual activity. The generic form of sildenafil is sildenafil-citrate, which is available in the following strengths: 25 mg, 50 mg, 100 mg, and 200 mg. The recommended starting dose for Sildenafil is 50 mg, taken as needed, about 30 minutes to an hour before sexual activity. It is important to follow the recommended dosage and not exceed the recommended dose. It is important to take sildenafil at the same time every day to maintain consistent results. It is important to complete the full course of treatment as prescribed, even if symptoms improve, to prevent the development of drug-resistant bacteria and maintain the effectiveness of the drug.

Side Effects:Common side effects of sildenafil may include headache, flushing, dizziness, nasal congestion, and indigestion. Sildenafil should not be taken with nitrates (often given in high doses) or alpha-blockers (often prescribed for chest pain). Nitrates are often given for chest pain, but should not be used with sildenafil. It is important to inform your doctor about all medications you are taking, including over-the-counter drugs and herbal supplements. Sildenafil may cause a temporary decrease or loss of hearing in some individuals. It is not known whether sildenafil is safe or effective in the long term. It should not be taken by individuals who are hypersensitive to sildenafil or those who have a history of liver problems or severe heart failure.

Precautions:Some individuals may develop priapism (a prolonged and painful erection) due to the increased blood flow to the penis following sexual stimulation, particularly when taken with sildenafil. If you have been prescribed sildenafil or have taken it with nitrates, it is important to inform your doctor about all medications you are taking, including over-the-counter drugs and herbal supplements. It is not recommended for individuals who have had a heart attack in the past, as it may have an effect on the heart.
