Sildenafil 25mg Tablet: Uses, Side Effects, Interactions, Pictures, Warnings & Dosing
What is Sildenafil 25mg used for?
Sildenafil 25mg is primarily used for the treatment of the following conditions:
- Erectile dysfunction, a medical condition where an individual cannot achieve or maintain an erection sufficient for satisfactory sexual performance.
- Pulmonary arterial hypertension, which refers to high blood pressure in the pulmonary arteries, affecting the lungs and the right side of the heart, leading to serious health issues.
In certain instances, Sildenafil may also be prescribed for other medical issues as determined by your healthcare provider, underscoring its versatility in treatment.
How does Sildenafil work (mechanism of action)?
Sildenafil operates by inhibiting the enzyme phosphodiesterase type 5 (PDE5), which leads to relaxation of blood vessels. The enhanced blood flow facilitates an erection when a man is sexually stimulated. For pulmonary arterial hypertension, Sildenafil assists in dilating blood vessels in the lungs, effectively lowering blood pressure and easing the heart's workload.
How is Sildenafil supplied (dosage forms)?
Sildenafil is offered under various brand names, allowing for patient choice:
- Viagra
- Revatio
The medication is available in several dosage forms, including:
- 25 mg, 50 mg, and 100 mg oral tablets
How should I store Sildenafil?
Oral Tablets: Store Sildenafil oral tablets at room temperature, ideally between 68°F to 77°F (20°C to 25°C). While they can tolerate short-term exposure to lower or higher temperatures, keeping them in a cool, dry environment is optimal to maintain their effectiveness.
