Quick Facts
- Viagra is used to treat erectile dysfunction in adult men.
- Its active ingredient is sildenafil citrate.
- Viagra increases blood flow to the penis to help achieve an erection.
- The standard doses are 25 mg, 50 mg, and 100 mg. A 200 mg dose is not typically recommended.
- Common side effects include headache, flushing, and indigestion.
- Should be taken about an hour before sexual activity.
- Avoid taking Viagra with nitrate medications, as this can cause a dangerous drop in blood pressure.
- Seek urgent medical help if you experience an erection lasting more than 4 hours, chest pain, or sudden vision loss.
What It Is and How It Works
Viagra works by inhibiting the phosphodiesterase type 5 (PDE5) enzyme, which results in the relaxation of blood vessels and increased blood flow to the penis during sexual stimulation. This mechanism helps men with erectile dysfunction achieve and maintain an erection.
Technically, sildenafil citrate does not directly cause an erection; rather, it facilitates the natural erectile response when a man is sexually aroused. Without sexual stimulation, sildenafil will not cause an erection.
Indications / Uses
Viagra is primarily indicated for the treatment of erectile dysfunction, a condition characterized by the inability to achieve or maintain an erection sufficient for satisfactory sexual performance. It may also be used in some cases for pulmonary arterial hypertension under different brand names and dosages.
Dosage Forms and Typical Dosing Considerations
Viagra is available in tablet form, with typical strengths of 25 mg, 50 mg, and 100 mg. Dosage selection is generally dependent on the patient\’s health, the severity of erectile dysfunction, and tolerability of the medication.
Higher doses such as 200 mg are not commonly recommended due to increased risk of side effects and lack of added efficacy shown in studies. Patients must adhere to the prescribed dosage and consult their healthcare provider for any adjustments.
How to Take It Correctly Step-by-Step
Viagra should be taken orally, with or without food, about one hour before sexual activity. Swallow the tablet whole with water. It is important to follow your healthcare provider\’s instructions on how to take this medication.
If a dose is missed (not applicable if taken as needed), do not double up the dose next time. Never take more than one dose of Viagra in 24 hours.

Contraindications & Precautions
Viagra is contraindicated in patients who take nitrate medications for chest pain, as the combination can lead to a dangerous drop in blood pressure. It should also be used with caution in patients with cardiovascular disease, liver or kidney impairment, and specific eye disorders.
Men who are advised against sexual activity due to health concerns, and those with known allergies to sildenafil or any of its ingredients, should avoid Viagra. Discuss any existing medical conditions with your healthcare provider before taking this medication.
