What It Is and How It Works
Viagra is a medication containing the active ingredient sildenafil citrate. It works by enhancing the effects of nitric oxide, a natural chemical the body produces to relax the muscles in the penis. This relaxation increases blood flow, enabling an erection in response to sexual stimulation.
Its action is predicated on the inhibition of an enzyme called PDE5, which regulates blood flow in the penis. By blocking PDE5, Viagra facilitates the maintenance of cGMP levels in the penis, thereby improving erectile function.
Indications / Uses
Viagra is approved primarily for the treatment of erectile dysfunction in adult males. It is not approved for use in women or children. There are instances where Viagra is used off-label for conditions such as pulmonary arterial hypertension, although such uses should only be pursued under the guidance of a healthcare provider.
Dosage Forms and Typical Dosing Considerations
Viagra is available in several dosages: 25 mg, 50 mg, 100 mg, and sometimes 200 mg, though the latter is not commonly prescribed. The 200 mg dosage is generally reserved for cases non-responsive to lower doses and requires strict medical supervision.
Dosing may vary based on factors such as age, kidney/liver function, coexisting health conditions, and the use of other medications. Taking more than the recommended dose can increase the risk of side effects and must be avoided without professional direction.
How to Take It Correctly Step-by-Step
Take Viagra with a full glass of water, about 30 to 60 minutes before sexual activity. It can be taken with or without food, although a high-fat meal may delay its onset. Stick to your prescribed dosage and do not double up if a dose is missed.
Common mistakes include taking higher doses than needed, consuming alcohol or grapefruit juice which can interfere with the medication\’s effectiveness, and using Viagra recreationally without medical advice.
Side Effects Common to Serious
Common Side Effects
Headaches, flushing, upset stomach, nasal congestion, and dizziness are often reported.
Less Common Side Effects
Vision changes, including increased sensitivity to light and blurred vision, can occur in some individuals.
Serious or Rare Side Effects
Priapism (prolonged erection lasting more than 4 hours), chest pain, and severe dizziness are serious effects requiring immediate medical attention.
Contraindications & Precautions
Viagra should not be used by individuals who are allergic to sildenafil or who are taking nitrates for chest pain, as this combination can lead to a dangerous drop in blood pressure. Special caution is advised for those with cardiovascular issues, severe liver or kidney disease, retinitis pigmentosa, and a history of stroke or heart attack.
Pregnant or breastfeeding women should avoid using Viagra as it’s not intended for these populations. Always consult a healthcare provider before starting this medication.
Drug, Food, and Supplement Interactions
Viagra can interact with nitrates, alpha-blockers, antihypertensives, and certain antifungals and antibiotics. Alcohol and grapefruit products should be avoided as they can amplify side effects. It\’s crucial to inform your healthcare provider about all medications and supplements you are currently taking to avoid potential interactions.
Price & Availability
The cost of Viagra can vary. Factors influencing price include dosage, pharmacy, insurance coverage, and brand versus generic options. While exact price data isn\’t provided here, it\’s important to note that generic forms are often less expensive and more widely covered by insurance plans.

Comparisons When Relevant
Comparing Viagra to other treatments for erectile dysfunction such as Cialis (tadalafil) and Levitra (vardenafil) can be informative. Each differs slightly in onset time and duration, but they share similar side effect profiles and interactions.
| Option | Typical Use | Key Pros/Cons | Notable Cautions |
