A medication primarily used to treat erectile dysfunction (ED) in men. Its active ingredient is sildenafil citrate, which belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. Viagra works by relaxing the muscles in the blood vessels of the penis, allowing for increased blood flow to the genital area when sexually stimulated.
Erectile dysfunction, characterized by the inability to achieve or maintain an erection sufficient for sexual intercourse, can have various underlying causes, including physical conditions such as diabetes, high blood pressure, or cardiovascular disease, as well as psychological factors such as stress or anxiety. Viagra does not address the underlying causes of ED but can help temporarily overcome the symptoms by facilitating erections.
Viagra is available in the form of oral tablets, typically taken as needed, approximately 30-60 minutes before anticipated sexual activity. The recommended dosage may vary depending on individual factors such as age, medical history, and response to treatment. It’s essential to follow the prescribed dosage and instructions provided by a healthcare professional to ensure safe and effective use.
While Viagra is generally well-tolerated, it may cause side effects in some individuals, including headache, flushing, nasal congestion, dizziness, and gastrointestinal upset. More serious side effects such as changes in vision, hearing loss, and priapism (a prolonged and painful erection lasting more than four hours) are rare but may occur. Individuals with certain medical conditions or taking certain medications may be at higher risk of experiencing adverse effects and should consult with a healthcare provider before using Viagra.
Viagra is not an aphrodisiac and does not increase sexual desire or libido. It only works in response to sexual stimulation and will not cause an erection without it. Additionally, Viagra does not protect against sexually transmitted infections (STIs) or serve as a form of contraception.
Overall, Viagra is a widely used and effective treatment for erectile dysfunction, helping many men regain confidence and satisfaction in their sexual lives.
