Sildenafil 10mg tablets contain sildenafil citrate, a medication used to treat erectile dysfunction (ED) in men. They work by increasing blood flow to the penis, making it easier to achieve and maintain an erection during sexual stimulation. This improved blood flow results from the inhibition of a specific enzyme, phosphodiesterase-5 (PDE5).
Understanding the Mechanism
PDE5 normally breaks down a chemical called cGMP, which is crucial for relaxing the muscles in the penis. By blocking PDE5, sildenafil allows cGMP levels to rise, leading to vasodilation–the widening of blood vessels. This increased blood flow is what facilitates an erection.
Important Considerations
Sexual stimulation is necessary for sildenafil to be effective; it doesn’t cause erections on its own. Sildenafil 10mg is typically taken as needed, about 30-60 minutes before sexual activity. Consult your doctor before using sildenafil, especially if you have heart conditions, high or low blood pressure, or are taking other medications. Side effects are possible and vary among individuals. Common ones include headaches, flushing, and nasal congestion.
Dosage and Precautions
The 10mg dose is often a starting point, and your doctor may adjust it based on your response and individual needs. Never exceed the prescribed dosage. Avoid grapefruit juice, as it can interact with sildenafil and increase its effects. This medication is only for men and should not be taken by women or children.
