Viagra, or sildenafil citrate, treats erectile dysfunction (ED) by increasing blood flow to the penis. This allows for a firmer erection suitable for sexual intercourse.
How Viagra Works
Viagra blocks an enzyme called phosphodiesterase-5 (PDE5). This enzyme normally breaks down a chemical called cyclic GMP, which is crucial for achieving and maintaining an erection. By inhibiting PDE5, Viagra increases cyclic GMP levels, leading to improved blood flow.
Viagra’s Uses Beyond ED
While primarily used for ED, Viagra also finds application in treating pulmonary arterial hypertension (PAH), a condition causing high blood pressure in the arteries leading to the lungs. It improves blood flow in these arteries, easing the strain on the heart.
Important Considerations
- Viagra is a prescription medication; you must consult a doctor before use. Certain medical conditions, like heart problems or low blood pressure, may preclude its use. Potential side effects include headaches, flushing, and nasal congestion. A doctor can discuss these and other possible risks with you. Interactions with other medications are possible. Provide your doctor a complete list of your current medications.
Dosage and Administration
Dosage varies depending on individual needs and medical history. Your doctor will determine the appropriate dose and frequency of use. It’s generally taken orally, about an hour before sexual activity.
Alternative Treatments
Lifestyle changes: Weight management, regular exercise, and quitting smoking can improve ED. Other medications: Several other medications treat ED, offering alternatives depending on individual health. Counseling: Addressing underlying psychological factors contributing to ED can be beneficial.
Seeking Medical Advice
Always consult a healthcare professional for accurate diagnosis and personalized treatment recommendations for ED or any other medical condition. They can assess your specific needs and provide the best course of action.
