What are Sildenafil Tablets?

Sildenafil is a generic treatment for erectile dysfunction (ED) that was first released under the brand name ‘Viagra’. It contains the same active ingredient as Pfizer’s branded Viagra (sildenafil citrate) but is a cheaper yet equally effective alternative. Taken one hour before sex, Sildenafil Tablets increase blood flow to the penis and enable it to become fully erect when aroused.

Buying Sildenafil Tablets - What You Need To Know

Sildenafil tablets are a generic, cheaper treatment for erectile dysfunction (ED) in men (they are not suitable to be used by women).

What Are Sildenafil Tablets Used for?

Sildenafil is an erectile dysfunction medication for men who struggle to get or maintain an erection during sexual intercourse. One Sildenafil tablet is taken up to one hour before sex to increase blood flow to the penis and help achieve and maintain a satisfactory erection.

Please note that Sildenafil will only help produce an erection if you’re sexually aroused. It won’t help you get an erection without stimulation.

Generic Viagra (Sildenafil): Sildenafil vs. Viagra

Sildenafil was first released by Pfizer under the well-known brand name Viagra, the ‘blue pill’ that has become iconic in the treatment of impotence. Once the patent on Viagra expired in 2013, generic treatments could be produced by drug manufacturers at a significant discount.

Sildenafil tablets contain the same active ingredient as Viagra and are just as effective as their branded counterpart, but they can be supplied at around half the cost.

How Does Sildenafil Work?

Sildenafil is a PDE-5 inhibitor that helps to treat erectile dysfunction by relaxing the blood vessels that feed blood to the penis, causing them to widen. This dilation allows a greater flow of blood to the penis, enabling it to become successfully erect when aroused.

Each manufacturer produces Sildenafil tablets in different sizes and shapes. However, they all contain the same active ingredient and should produce the same effect.

Key Sildenafil Features

  • A cheaper alternative to branded Viagra (yet just as effective)
  • Helps men to achieve and maintain an erection by increasing blood flow to the penis
  • May be effective in as little as 20 minutes
  • The effects can last for up to 5 hours
  • Can be purchased discreetly from The Independent Pharmacy with next-day delivery

Sildenafil Dosage & Effects

Sildenafil 50mg tablets are the starting doses for patients who have not taken Sildenafil or other erectile dysfunction treatments before. Sildenafil 50mg is normally of sufficient strength to treat most cases of ED, but — as is the case for all ED medicines — Sildenafil isn’t always successful the first time you take it. It is recommended to take Sildenafil at least eight times to allow it to build up a full effect before trying a different erectile dysfunction treatment.

Sildenafil 100mg tablets are the highest doses for patients who have tried Sildenafil or other erectile dysfunction treatments without achieving satisfactory results. If you have tried Sildenafil 50mg and it has proved ineffective, increasing the strength to 100mg may improve results.

Sildenafil 25mg tablets are the lowest strength of Sildenafil/generic Viagra available. Sildenafil 25mg tablets are normally used in patients who have experienced side effects from Sildenafil when taking the starting doses of 50mg tablets. Although they are the lowest-strength treatment, Sildenafil tablets 25mg can still successfully treat ED in many patients. Even if the root ED cause is psychological, its effect can help to break the cycle of anxiety associated with being unable to achieve and maintain a satisfactory erection.

Sildenafil is not currently available in liquid form at our pharmacy. We also do not stock any Viagra injections like Caverject.

Pharmacist tip: Sildenafil should be taken 30 minutes to 1 hour before sexual intercourse. It lasts for 4-5 hours. You should try to avoid high-fat meals during this period, as they may reduce the effectiveness of Sildenafil.

What Sildenafil Tablets Can & Can’t Do

Sildenafil increases the blood flow to the penis, helping to achieve and maintain a satisfactory erection. Sildenafil tablets will only help to produce an erection if you are sexually aroused. It will not help to get an erection without stimulation.

Why is Sildenafil cheaper than Viagra?

Sildenafil citrate is the name of the drug contained in the branded medicine Viagra. Now that the patent on Viagra has expired, other companies may make ‘generic’ versions of the drug. However, they still must receive a product licence from the MHRA to ensure their safety. Due to increased competition, ‘generic’ Sildenafil for erectile dysfunction is available at a much lower price but still has the same effect and quality you would expect from a branded medication. Another generic ED treatment is now also available; Tadalafil 10mg & 20mg tablets are available as of November 2017 as a generic alternative ED treatment to the branded Cialis tablets.

When you buy Viagra online, it’s important that you get your pills from a reputable online pharmacy. As Viagra is not sold over the counter in the UK, you will always need to undertake a short, free medical consultation.

Sildenafil tablets are even cheaper than the new over-the-counter ED treatment, Viagra Connect.

We are able to supply Sildenafil tablets from the following manufacturers: Almus, Actavis, Macleod, Milpharm, Mylan, Teva, and Torrent Pharma. If you have any special requirements for a certain manufacturer, please let us know.

Pharmacist tip: Sildenafil should be taken 30 minutes to 1 hour before sexual intercourse. It lasts for 4 – 5 hours, and you should try to avoid high-fat meals around the same time, as it may reduce the effectiveness of Sildenafil.

Sildenafil directions

You should take one Sildenafil tablet at least an hour before sexual activity. However, it’s important to note the following:

  • Sildenafil can take up to an hour to take effect, although it can be effective in as little as 20 minutes in some men.
  • Sildenafil can produce an effect for up to 5 hours.
  • You should never take more than one erectile dysfunction treatment (including Viagra, Cialis, or Levitra) in a 24-hour period.
  • You should take Sildenafil tablets on an empty stomach and try to limit your alcohol intake to ensure it remains effective.

Sildenafil does not work for everyone the first time they use it. If it doesn’t work the first time for you, you should not give up, as the guidance states that you should try your current dose of Sildenafil at least 8 times before trying an alternative treatment.

If you find Sildenafil effective and do not experience any serious side effects, you can buy Sildenafil online via your online account. If you followed the above guidance and still find Sildenafil to be ineffective, you may wish to try a different medicine, such as Cialis or Spedra.

Sildenafil ingredients

Each Sildenafil tablet contains sildenafil as the active ingredient at a strength of either 25mg, 50mg or 100mg.

Each tablet also contains: microcrystalline cellulose, calcium hydrogen phosphate anhydrous, croscarmellose sodium, magnesium stearate, poly(vinyl alcohol), titanium dioxide (E171), macrogol 3350 & talc.

Please note that different manufacturers may use different inactive ingredients. Please contact us for specific details or if you require a specific brand.

Sildenafil side effects

If you do experience side effects from Sildenafil, they may include headache, flushing, lightheadedness and rarely a stuffy nose or indigestion. Sildenafil has a small risk of nausea, vomiting, diarrhoea, and skin rash, as with all medicines. Please read the Patient Information Leaflet enclosed with your medicines for a full list of side effects.

If you experience any adverse effects from taking your prescribed medicine it is important to let us know immediately.

Sildenafil warnings

Sildenafil tablets may not be suitable if any of the following apply:

  • You suffer from heart disease or heart rhythm problems
  • You have had a heart attack or stroke within the last six months
  • You have high or low blood pressure
  • You suffer from liver or kidney disease
  • You are a haemophiliac
  • You suffer from sickle cell anaemia or leukaemia
  • There is a physical deformity of the penis
  • You suffer from retinitis pigmentosa
  • You have a stomach ulcer.

If any of the above apply, it is important to let your doctor know so they can judge whether Sildenafil tablets will be safe for you to use.

Sildenafil tablets can lower the blood pressure. For most men, this isn’t a concern. However, this effect on blood pressure can be exaggerated if Sildenafil is taken with a nitrate drug, such as Isosorbide or Glyceryl Trinitrate (GTN). If taking nitrate drugs, then Sildenafil tablets should not be used. Sildenafil tablets should be used with caution if combined with alpha-blockers due to the potential hypotensive effects.
