Sildenafil is the active ingredient in Viagra, a medication primarily used to treat erectile dysfunction (ED) in men. It works by increasing blood flow to the penis, helping achieve and maintain an erection.
Here’s what you should know:
- How it works: Sildenafil inhibits an enzyme called phosphodiesterase-5 (PDE5). This allows more cyclic GMP to build up, relaxing blood vessels and increasing blood flow. Dosage: Dosage varies depending on individual needs and doctor’s recommendations. Common starting doses range from 25mg to 100mg, taken as needed, typically about one hour before sexual activity. Side effects: Common side effects include headache, flushing, nasal congestion, and upset stomach. More serious side effects are rare but possible. Always consult a doctor. Precautions: Sildenafil is not suitable for everyone. It should not be used by individuals with certain heart conditions, low blood pressure, or those taking specific medications, including nitrates. Consult your physician before use. Alternatives: Other medications are available to treat ED, if sildenafil isn’t suitable or effective. Your doctor can help determine the best option for you.
Remember to always speak with your doctor or another qualified healthcare professional before starting any new medication, including sildenafil. They can assess your health, discuss potential risks and benefits, and determine the appropriate dosage for your individual circumstances.
Schedule a consultation with your doctor. Discuss your medical history and any medications you currently take. Follow your doctor’s instructions precisely regarding dosage and usage. Report any side effects to your doctor immediately.
