Understanding Pfizer Viagra: Uses, Dosage, and Side Effects

Pfizer Viagra, generically known as sildenafil, is a prescription medication commonly prescribed for the treatment of erectile dysfunction (ED) in men. It operates by enhancing blood flow to the penis, facilitating the achievement and maintenance of an erection when sexual arousal occurs. This thorough guide delves into the fundamental aspects of the Pfizer Viagra pill, exploring its primary uses, dosage guidelines, potential side effects, and necessary safety precautions.

Common Uses of Pfizer Viagra

Sildenafil is predominantly utilized for addressing erectile dysfunction. Beyond this primary indication, its uses extend to:

• Pulmonary arterial hypertension (PAH): Pfizer Viagra is marketed under the brand name Revatio for treating PAH, a serious condition that affects blood vessels in the lungs.
• Enhancement of exercise capacity in adults diagnosed with PAH.

The mechanism of Viagra involves the inhibition of an enzyme called phosphodiesterase type 5 (PDE5), resulting in the relaxation of blood vessels and improved blood flow.

Dosage Information

The typical starting dosage of Pfizer Viagra for most men is 50 mg, administered as needed approximately one hour prior to engaging in sexual activity. However, adjustments to your dosage may be made by your healthcare provider based on individual efficacy and tolerability. Key dosage guidelines include:

• The maximum permissible dose is 100 mg.
• The minimum recommended dose is 25 mg.
• Refrain from taking more than one dose within a 24-hour timeframe.

It is crucial to adhere strictly to your healthcare provider’s instructions and not to exceed the prescribed dosage.

• Eye disorders, including retinitis pigmentosa.
