Understanding Viagra: A Comprehensive Guide

How Does Viagra Work?

Viagra works by increasing blood flow to the penis, thereby helping men achieve and maintain an erection. This is accomplished by blocking the action of a protein called phosphodiesterase-type 5 (PDE-5), which typically breaks down another protein called cyclic guanosine monophosphate (cGMP). The latter is responsible for causing more blood to flow into the penis, leading to an erection4. By inhibiting PDE-5, Viagra ensures that blood flow to the penis is not prematurely stopped.

Usage and Dosage

Viagra is taken as needed to treat ED in adults4. It is most effective about 1 hour after it’s taken, and its effects can last for a few hours. However, the exact duration can vary from person to person. It’s important to note that Viagra does not protect against sexually transmitted diseases.

Cost Considerations

While Viagra can start at $80 per dose, the generic version, sildenafil, can cost as little as $25. It’s also worth noting that some patients may be eligible for savings on their prescriptions.

Side Effects and Safety

Like all medications, Viagra can have side effects. Therefore, it’s crucial to discuss any potential risks and benefits with your doctor before starting treatment.

In conclusion, Viagra has revolutionized the treatment of ED, offering hope to millions of men. However, as with any medication, it’s essential to use it responsibly and under the guidance of a healthcare professional.
