Viagra, generically known as sildenafil, is a medication primarily used to treat erectile dysfunction (ED) in men. ED is characterized by the inability to achieve or maintain an erection sufficient for satisfactory sexual performance. Viagra works by increasing blood flow to the penis during sexual stimulation, which assists in achieving an erection. Additionally, sildenafil is also utilized in treating pulmonary arterial hypertension (PAH), a serious condition characterized by high blood pressure affecting the arteries in the lungs, thereby improving exercise capacity and overall quality of life.
It is essential to understand that Viagra does not provide a cure for ED nor does it increase sexual desire. Importantly, it does not offer any protection against sexually transmitted diseases, including HIV. Understanding these distinctions is crucial for informed use.
Viagra is available in tablet form and is intended for oral use. For optimal results in treating ED, it should be taken approximately one hour before planned sexual activity. However, it is also effective when taken anytime from 30 minutes to 4 hours prior to sexual intercourse. The maximum recommended dosing frequency is once within a 24-hour period. The medication can be taken with or without food; however, meals that are high in fat may delay its absorption and effectiveness.
If prescribed for the management of PAH, the typical dosing regimen is three times a day. It is crucial to adhere strictly to your healthcare professional's instructions regarding timing and dosage to ensure safety and efficacy.
In some cases, Viagra may be prescribed off-label for other medical conditions. Always consult your healthcare provider if you have questions regarding the potential applications of this medication beyond ED.

- Inform your doctor if you are allergic to sildenafil or any other medications.
- Discuss all medications you are currently taking, including over-the-counter products and herbal supplements, to avoid potentially harmful interactions.

Prior to taking Viagra, discuss dietary restrictions with your healthcare provider, especially regarding the consumption of grapefruit juice, which may interact adversely with the medication.
