Viagra, or sildenafil, primarily treats erectile dysfunction (ED), a condition affecting a man’s ability to achieve or maintain an erection firm enough for satisfactory sexual intercourse. It works by increasing blood flow to the penis.
How Viagra Works
Viagra inhibits an enzyme called phosphodiesterase-5 (PDE5). This allows for greater blood vessel dilation in the penis, resulting in improved erectile function. The effect is only triggered by sexual stimulation; Viagra doesn’t cause erections spontaneously.
Viagra’s Prescription and Usage
A doctor will determine the appropriate dosage based on individual health and medical history. Common side effects include headaches, flushing, nasal congestion, and visual disturbances. These are usually mild and temporary. Always follow your doctor’s instructions regarding dosage and frequency of use. Never exceed the recommended dose.
Important Considerations
Viagra interacts with certain medications, such as nitrates. Taking them together can cause a dangerous drop in blood pressure. Inform your doctor about all medications you are currently taking before starting Viagra. Also discuss any pre-existing heart conditions or other health concerns. Viagra is not suitable for everyone.

Alternative Treatments
Besides Viagra, other treatments for ED exist, including other medications, lifestyle changes (like weight loss and exercise), and psychological therapy. Your doctor can help determine the best approach for your specific situation.
