What is Sildenafil and How Does It Work?

Sildenafil is a clinically proven medication used to treat erectile dysfunction (ED) in men.

As the active ingredient originally found in Viagra, Sildenafil belongs to a class of drugs known as PDE5 inhibitors.

It works by relaxing the blood vessels in the penis, allowing for increased blood flow when a man is sexually stimulated.

This process helps achieve and maintain an erection sufficient for sexual activity.

At Prescriptsy, we provide a secure environment where this treatment is now available through online consultation .

This ensures that every patient is assessed by an EU-licensed doctor to determine if Sildenafil is the correct and safe choice for their specific health profile.

Once approved, your prescription is issued and dispensed by an EU-regulated pharmacy, ensuring you receive genuine, high-quality medication.

  • Discretion: We understand that ED is a private matter. Your medication is delivered in plain, discreet packaging with no indication of the contents.
  • Legitimacy: We only work with EU-licensed doctors and regulated pharmacies. Every treatment requires a clinical assessment to ensure patient safety.
  • Convenience: Skip the waiting room. Our online consultation process allows you to seek professional medical advice from the comfort of your home.

To meet the diverse needs of our patients, we offer Sildenafil in various strengths and pack sizes. Your doctor will determine which dosage is appropriate for you during your consultation.

  • Sildenafil 25 mg: Available in packs of 4, 8, 12, 16, 20, 24, 28, and 32 tablets.

  • Sildenafil 100 mg: Available in packs of 4, 8, 12, 16, 20, 24, 28, 32, 36, and 64 tablets.

How to Take Sildenafil Properly

For the best results and to ensure your safety, Sildenafil must be taken exactly as directed by your prescribing physician. Follow these general guidelines:

The tablet should be swallowed whole with water approximately 30 to 60 minutes before planned sexual activity.

While it can be taken with or without food, a heavy or high-fat meal may delay the onset of the medication’s effects.

It is important to remember that Sildenafil is not an aphrodisiac; sexual stimulation is required for the medication to work effectively.

Never take more than one dose in a 24-hour period. Exceeding the recommended dose does not increase efficacy but significantly increases the risk of serious side effects.

Important Safety Information and Contraindications

CRITICAL WARNING: Sildenafil is a potent medication and is not suitable for everyone. A thorough medical consultation is mandatory to prevent dangerous drug interactions and complications.

Contraindications

You must NOT take Sildenafil if you:

  • Are taking "nitrates" (often prescribed for chest pain/angina), as this combination can cause a life-threatening drop in blood pressure.
  • Use recreational drugs known as "poppers" (amyl nitrite).
  • Have severe heart or liver problems.
  • Have recently had a stroke or a heart attack.
  • Have low blood pressure or certain rare inherited eye diseases (such as retinitis pigmentosa).
  • Are allergic to sildenafil or any of the ingredients in the medication.

Proper Usage and Precautions

Before you buy Sildenafil online, you must disclose your full medical history to our doctors, especially if you have sickle cell anaemia, leukaemia, multiple myeloma, or any deformity of the penis (such as Peyronie’s disease).

Sildenafil should not be used in combination with other oral or local erectile dysfunction treatments.

Potential Side Effects

Like all medicines, Sildenafil can cause side effects, although not everyone gets them. Common side effects may include headaches, facial flushing, indigestion, stuffy nose, and dizziness.

Most side effects are mild and temporary. However, if you experience any of the following, seek immediate medical attention:

  • Chest pains: If this occurs during or after intercourse, do not use nitrates but seek emergency help.
  • Priapism: A prolonged and sometimes painful erection lasting longer than 4 hours.
  • Sudden loss of vision or hearing.
  • Allergic reactions: Including wheezing, difficulty breathing, or swelling of the eyelids, face, lips, or throat.

Prescriptsy is committed to your health and safety. Always consult with a healthcare professional through our online consultation platform before beginning any new treatment.

Medical information

Sildenafil is a phosphodiesterase type 5 (PDE5) inhibitor — the same active ingredient originally developed as Viagra — used for the treatment of erectile dysfunction (ED) in adult men.

It works by inhibiting PDE5 in the corpus cavernosum, which enhances the vasodilatory effect of nitric oxide released during sexual stimulation, increasing penile blood flow and enabling an erection.

Effects typically begin within 30–60 minutes and last for 4–6 hours. Sildenafil does not cause spontaneous erections; sexual stimulation is still required.

PDE5 inhibitors are contraindicated with nitrate medications due to the risk of severe hypotension.

A prescriber must assess your cardiovascular fitness for sexual activity, check for interactions with alpha-blockers and other antihypertensives, and confirm there are no underlying conditions requiring further investigation before treating ED.

  1. Compare pharmacies – Browse Sildenafil dosages from registered UK pharmacies on Prescriptsy.
  2. Complete the health questionnaire – Describe your ED symptoms, cardiovascular history, blood pressure, and current medications including any nitrate use.
  3. Medical assessment – A registered doctor evaluates your cardiovascular fitness and confirms that sildenafil is safe and appropriate.
  4. Discreet delivery – Your ED medication is sent in plain, unmarked packaging to your chosen address.

Prescriptsy provides a confidential online consultation for erectile dysfunction treatment with registered prescribers.
