25 mg sildenafil is a low dose of the medication commonly known as Viagra. It’s a phosphodiesterase-5 (PDE5) inhibitor, meaning it works by increasing blood flow to the penis. This increased blood flow facilitates an erection in response to sexual stimulation.
How Sildenafil Works
Sildenafil blocks PDE5, an enzyme that breaks down cGMP. cGMP is a substance that relaxes the muscles in the penis, allowing increased blood flow. By inhibiting PDE5, sildenafil allows cGMP levels to remain higher for longer, resulting in improved erectile function. It’s crucial to remember that sildenafil only works when stimulated sexually; it doesn’t cause an erection on its own.
Important Considerations for 25 mg Sildenafil
The 25 mg dosage is often prescribed for individuals new to sildenafil or those with specific health conditions. It allows for a gradual introduction to the medication and helps to minimize potential side effects. Always follow your doctor’s instructions regarding dosage and frequency of use. Side effects, while rare at this dosage, can include headaches, flushing, nasal congestion, and visual disturbances. Consult a medical professional immediately if you experience any serious adverse effects.
