What It Is and How It Works
Viagra, or sildenafil, is part of a medication class called phosphodiesterase type 5 (PDE5) inhibitors. Its primary role is to enhance erectile function by increasing blood flow to the penis during sexual stimulation. This is achieved by inhibiting the PDE5 enzyme which is responsible for breaking down a chemical called cGMP. Increased levels of cGMP lead to relaxation of the smooth muscle in the penis, allowing for increased blood flow.
Indications / Uses
Viagra is primarily prescribed for erectile dysfunction, which is the inability to achieve or maintain an erection sufficient for satisfactory sexual intercourse. While it can help achieve an erection, sexual stimulation is still required for the medication to work. Viagra is also sometimes used off-label for other conditions as determined by a healthcare provider, though these uses are outside the standard indications and should be carefully considered with professional guidance.
Dosage Forms and Typical Dosing Considerations
Viagra comes in oral tablet forms with strengths typically ranging from 25 mg to 100 mg. The 200 mg dosage is less commonly prescribed and typically reserved for specific cases under strict medical supervision. Factors like age, health status, concurrent medications, and response to treatment influence the dosing. It’s crucial that patients follow the prescribed instructions provided by their healthcare practitioner, and never exceed the recommended dose.
How to Take It Correctly Step-by-Step
Viagra should be taken orally, approximately 30 to 60 minutes before sexual activity. It can be taken with or without food, although high-fat meals might delay its effectiveness. Never double doses to make up for a missed one, and consult a doctor if a dose is missed regularly. Viagra should be stored in a cool, dry place away from direct sunlight.

Contraindications & Precautions
Contraindications for Viagra include use in patients taking nitrate drugs for angina or heart issues, as this can cause a dangerous drop in blood pressure. Caution is advised for individuals with cardiovascular conditions, severe liver or kidney problems, or those who have experienced a recent stroke or heart attack. Pregnant and breastfeeding women should avoid this medication unless deemed necessary by their doctor.
Drug, Food, and Supplement Interactions
Viagra can interact with several types of medications, particularly nitrates, certain blood pressure medications, and some antibiotics. Alcohol consumption should be limited as it can interfere with the medication’s effectiveness and increase certain side effects. Patients should inform their healthcare provider about all prescription and over-the-counter medications they are taking, including herbal supplements.
