Viagra is a brand name for the drug sildenafil citrate, which is used to treat erectile dysfunction (ED) in men. It works by increasing blood flow to the penis, thereby helping to achieve and maintain an erection.
Viagra is available in tablet form, with the most common dosage being 50mg. The tablet should be taken orally with water, approximately 30 minutes to 1 hour before sexual activity. It is important not to take more than one tablet per day, and to only take it as needed for sexual activity.
The dosage of Viagra may vary depending on individual factors such as age, overall health, and the severity of ED. The healthcare provider may adjust the dosage based on the individual’s response to the medication.
It is important to note that Viagra does not provide sexual stimulation and will not work without sexual arousal. Additionally, it should not be taken by individuals who are allergic to sildenafil or any of its ingredients, or who are taking nitrates for chest pain or heart problems.
Possible side effects of Viagra include headache, flushing, indigestion, nasal congestion, and dizziness. In rare cases, it may cause more serious side effects such as sudden vision or hearing loss, or an erection lasting longer than 4 hours (priapism). If any of these side effects occur or if there are any signs of an allergic reaction, medical attention should be sought immediately.
Overall, Viagra is an effective medication for treating ED in men, but it is important to follow the recommended dosage and to be aware of the possible side effects and contraindications. It is always best to consult with a healthcare provider before starting any new medication.
