What is Sildenafil used for?

Sildenafil (Viagra) is a generic prescription erectile dysfunction (ED) medication used for helping men achieve and maintain an erection when sexually aroused. It improves blood flow to the penis for stronger erections. Sildenafil has been helping men overcome ED symptoms since 1998 and is trusted by millions each year for improving confidence in the bedroom.

How Sildenafil works

Sildenafil belongs to a class of medications called PDE5 inhibitors. The PDE5 enzyme is responsible for tightening blood vessels and reducing circulation to stop an erection. Blocking PDE5 allows the blood vessels in the penis to relax and widen so more blood can enter. While Sildenafil does not cause erections, it supports your body’s response to stimulation and helps with achieving and maintaining a firm erection.

Pulmonary arterial hypertension (PAH) patients may also be prescribed Sildenafil. This condition occurs when the blood vessels narrow in the lungs, causing high blood pressure and symptoms like fatigue, dizziness, and shortness of breath. Sildenafil is not a cure for PAH, but it can significantly slow the progression of PAH symptoms and improve quality of life.

Is Sildenafil safe?

Sildenafil is well-tolerated by most men. As the original medication for ED, it has been extensively studied and researched. Not everyone will experience side effects, and clinical reports have found that most side effects are mild and temporary.1 Speak to your physician to find out if Sildenafil is safe for you.

An online Canadian pharmacy like RxConnected is considered a top choice for ordering Sildenafil, especially if convenience and affordability are crucial to you. RxConnected is CIPA and IPABC certified, designating it a trusted and reliable way for Americans to access cheap Sildenafil.

Directions, Cautions, and Side Effects

Take Sildenafil by mouth with a glass of water about 30–60 minutes before sexual activity. Sildenafil has a quick onset time of as fast as 15 minutes for some men. After a dose, you will have approximately a 4-hour window where Sildenafil will help you achieve a stronger erection when sexually stimulated. Other tips for maximizing the benefits of Sildenafil:

  • Avoid taking Sildenafil with heavy or high-fat meals. Heavy meals will delay its onset.
  • Do not combine with recreational drugs or nitrate medications.
  • Follow your exact prescribed dosage.
  • Do not take more than one pill per day.

Cautions

Sildenafil should never be taken with nitrate medications, which can cause a dangerous drop in blood pressure if combined. Men who have blood pressure conditions, liver or kidney disease, or a history of stroke or heart attack may require strict medical supervision when taking Sildenafil. Other cautions include:

  • Avoid alcohol, which may increase side effects like dizziness or flushing
  • Sildenafil may interact with alpha-blockers, antifungals, HIV medications, and certain antibiotics
  • Vision or hearing loss caused by Sildenafil is rare but may occur
  • Sildenafil may cause priapism, a dangerous condition where an erection lasts longer than 4 hours

If you experience light-headedness during sex, vision or hearing loss, or a prolonged and painful erection, get medical help right away to reduce the risk of permanent damage. Always speak to your doctor if you have any concerns about Sildenafil.

Sildenafil Side Effects

Common side effects of Sildenafil include:

  • Headache
  • Facial flushing
  • Nasal congestion
  • Indigestion
  • Dizziness

These effects are typically mild and temporary, with many users experiencing little to no discomfort. However, Sildenafil may cause some rarer but more more serious side effects, including:

  • Back pain
  • Chest pain
  • Vision or hearing loss
  • Fainting
  • Prolonged erection (priapism)

If any of these severe side effects occur, seek medical attention immediately. Consult your doctor for a complete and comprehensive list of Sildenafil side effects.

I’ve been taking Domperidome/Motilium for years. I have Gastroparesis and it definitely works for me. The Customer Service is great. All of them that I’ve placed my orders for years are very helpful and professional. I’m in the USA so there are tariffs making the medication more expensive but I must take it. All ways a good experience!
