Viagra, or sildenafil, primarily treats erectile dysfunction (ED). It enhances blood flow to the penis, facilitating an erection with sexual stimulation.
Here’s what you should know:
- How it works: Viagra inhibits an enzyme called PDE5, increasing levels of cGMP, a chemical that relaxes blood vessels. Dosage: Typical starting dose is 50mg, taken as needed, about 1 hour before sexual activity. Your doctor will determine the appropriate dose for you. Who should use it: Men diagnosed with ED by a healthcare professional. Who shouldn’t use it: Individuals with certain heart conditions, low blood pressure, or those taking specific medications (nitrates, for example). Always consult your doctor before use.
Beyond ED, Viagra has shown promise in treating:
- Pulmonary arterial hypertension (PAH): A condition causing high blood pressure in the arteries leading to the lungs. A different formulation (Revatio) is often used for this.
Important Considerations:
Side effects: Common side effects include headache, flushing, nasal congestion, and upset stomach. Less common but more serious side effects exist. Discuss any concerns with your doctor. Interactions: Viagra can interact with other medications. Inform your doctor about all medications and supplements you take. Prescription: Viagra requires a prescription. Obtain it from a licensed healthcare provider after a thorough consultation. Safety: Always follow your doctor’s instructions and only purchase Viagra from reputable pharmacies to ensure authenticity and safety.
