Quick Facts

  • Viagra is primarily used to treat erectile dysfunction.
  • It belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors.
  • Commonly comes in tablet form with standard doses of 25mg, 50mg, and 100mg.
  • A 200mg dose is not standard and typically not recommended without professional advice.
  • Viagra works by increasing blood flow to the penis to help achieve and maintain an erection.
  • It is usually effective within 30 to 60 minutes, lasting for up to 4 hours.
  • Common side effects include headaches, flushing, and dizzy spells.
  • Interactions may occur with nitrates, a common treatment for chest pain.
  • Seek urgent medical help for symptoms like chest pain or an erection lasting longer than 4 hours.

What It Is and How It Works

Viagra is a medication used to treat erectile dysfunction by enhancing the effects of nitric oxide released in the penis during sexual stimulation. Nitric oxide increases cGMP, a substance that relaxes the blood vessels, allowing increased blood flow necessary for an erection. Technically, Viagra inhibits PDE5, an enzyme that breaks down cGMP. By inhibiting this enzyme, Viagra helps to maintain increased levels of cGMP, thus facilitating erections.

Indications / Uses

Viagra is approved for the treatment of erectile dysfunction in adult men. ED can result from various factors, including physical and psychological conditions. It may also be considered for other vascular conditions under the supervision of a healthcare professional. Off-label use may exist, but such use should always be guided by a qualified physician.

Dosage Forms and Typical Dosing Considerations

Viagra is typically available in tablet forms of 25mg, 50mg, and 100mg. While the 200mg dose is not standard, some might consider higher doses if the lower doses are ineffective, but only under strict healthcare supervision. Factors influencing dosing include age, kidney and liver function, concurrent medications, and individual response to the medication. A healthcare professional should always oversee these decisions.

How to Take It Correctly Step-by-Step

Take Viagra as prescribed by your healthcare provider. Usually, it\’s taken 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. Never exceed the prescribed dose, and do not take more than one dose in 24 hours. Store it at room temperature, away from moisture and heat. If you miss a dose and it\’s time for the next planned sexual activity, take it only at that time.

It is also contraindicated with nitrate medications. Caution is needed for the elderly, those with kidney or liver disease, and individuals with an incurable penile deformity.

Drug, Food, and Supplement Interactions

Viagra may interact with nitrates (found in some medicines for chest pain), leading to a hazardous drop in blood pressure. It can also interact with certain medications used for high blood pressure, HIV treatment, and specific antifungal or antibiotic medications. Avoid combining Viagra with recreational drugs like \”poppers\” (amyl nitrates), and consult a healthcare provider regarding all medications and supplements you are taking before starting Viagra.
