Viagra

Product Description

Viagra (sildenafil) is a prescription medicine for adult men with erectile dysfunction (ED).

It improves blood flow to the penis and helps achieve and maintain an erection only with sexual stimulation.

It does not increase sex drive and does not affect hormone levels.

Safety Information

• Use only as prescribed by a licensed healthcare provider.
• Do not take with nitrates or “poppers” (risk of dangerous drop in blood pressure).
• Tell your doctor about any heart disease, blood pressure problems, liver or kidney disease, eye disorders, and all other medicines or supplements you use.
• Get emergency help if you have chest pain, sudden vision or hearing loss, severe dizziness, fainting, or an erection lasting more than 4 hours.

Dosage Instructions

• Take the dose prescribed by your doctor before anticipated sexual activity.
• Swallow the tablet with water; it can be taken with or without food (very fatty meals may delay the effect).
• Do not take more than one prescribed dose within a short period.
• Never increase the dose or frequency on your own.

Who Should Avoid Viagra?

Viagra is usually not appropriate if you:

• take nitrates for chest pain/angina or certain nitric oxide–donor drugs;
• have been told to avoid sexual activity due to serious heart problems;
• recently had a heart attack, stroke, or serious arrhythmia;
• have certain rare inherited eye diseases or a history of sudden vision loss related to PDE5 inhibitors;
• are a woman, under 18 years of age, or using it for recreational/non-medical purposes.

Always ask a healthcare professional if Viagra is safe for you.

Potential Side Effects

Common side effects may include:

• headache;
• flushing;
• indigestion;

• temporary changes in vision (such as color tinge or sensitivity to light).

Stop using and seek urgent medical care if you notice:

Ordering and Quality Assurance

• Buy Viagra only with a valid prescription from licensed pharmacies.
• Avoid websites offering “no prescription,” unrealistically low prices, or aggressive spam — these are common signs of counterfeit products.
• Check the packaging, expiry date, and that blisters are sealed and intact.
• If you are unsure about authenticity or safety, consult your doctor or pharmacist before taking the medicine.
