Quick Facts

• Primarily used for treating erectile dysfunction (ED) in men.
• Works by increasing blood flow to the penis during sexual arousal.
• Commonly available in tablet form.
• Onset typically within 30 to 60 minutes; duration is up to 4 hours.
• Common side effects: headache, flushing, indigestion.
• Should not be used with nitrates or other medications affecting blood pressure.
• Not for use in women or children.
• Urgent help needed if an erection lasts longer than 4 hours.

What It Is and How It Works

Viagra contains the active ingredient sildenafil, a phosphodiesterase type 5 (PDE5) inhibitor. It works by blocking the breakdown of cyclic guanosine monophosphate (cGMP), a molecule that relaxes smooth muscle tissue in the penis, thereby enhancing blood flow and facilitating an erection in response to sexual stimulation.

Indications / Uses

Viagra is primarily approved for the treatment of erectile dysfunction. In certain cases, it\’s used off-label for pulmonary arterial hypertension (under specialist care) due to its vasodilatory effects on blood vessels.

Dosage Forms and Typical Dosing Considerations

Viagra is available in 25 mg, 50 mg, 100 mg, and occasionally 200 mg tablets. The typical starting dose is 50 mg. A 200 mg dose may be considered in rare cases where lower doses are not effective, under direct medical supervision. Factors affecting dosage include age, liver and kidney function, concurrent medications, and overall health status.

How to Take It Correctly Step-by-Step

Take Viagra approximately 30 to 60 minutes before sexual activity. It can be taken with or without food, although high-fat meals may delay its effect. Do not take more than one dose in 24 hours. Store at room temperature and keep out of reach of children.

If a dose is missed, do not double the next dose. Instead, continue with the usual dosing schedule if it\’s associated with regular use, as sometimes directed for pulmonary hypertension.

Side Effects Common to Serious

• Common side effects: headache, flushing, upset stomach, abnormal vision.
• Less common side effects: dizziness, rash, stuffy or runny nose.
• Serious side effects: vision changes, sudden hearing loss, chest pain, irregular heartbeat. Immediate medical attention is needed for prolonged erection (priapism), as it can permanently damage the penis.

Contraindications & Precautions

Viagra should not be used in individuals allergic to sildenafil or any components of the tablet, those taking nitrates for heart conditions, or individuals with certain cardiovascular issues. Special caution is advised for elderly patients and those with kidney or liver problems, as dosage adjustment may be necessary.

Pregnant women or breastfeeding mothers should avoid sildenafil unless prescribed for other conditions by a specialist.

Drug, Food, and Supplement Interactions

Key interactions include nitrates, which can cause a dangerous drop in blood pressure, and certain other antihypertensives. Alcohol can also lower blood pressure further, which can enhance side effects. Patients should inform healthcare providers of all medications, including over-the-counter drugs and supplements, to avoid potential interactions.

Price & Availability

Viagra\’s price varies based on the brand, dose, and pharmacy. In Canada, purchasing Viagra from an online pharmacy may offer cost savings, but it should only be done from reputable sources to ensure safety.
