Sildenafil Tablets 25mg, 50mg & 100mg

Sildenafil starts from £8.99 for 4 x 25mg tablets. 50mg starts from £9.99 for 4 tablets and 100mg from £11.99 for 4 tablets, with 8, 12 and 16-tablet packs also available. Every price includes your online consultation, review by a UK-registered prescriber and your prescription – there are no consultation fees, prescription charges or subscriptions. Delivery is free on orders over £40 and £3.49 below that.

At Access Doctor the lowest price per tablet for sildenafil 100mg is the 16-tablet pack at £42.99, which works out at £2.69 per tablet. The smallest pack is 4 tablets for £11.99. 100mg is the highest licensed strength and is prescription-only – it is usually prescribed for men who have tried 50mg without enough effect and have not had troublesome side effects. Your prescriber will confirm whether 100mg is right for you.

Yes. Sildenafil is the active ingredient in Viagra, and generic sildenafil tablets contain the same medicine at the same strengths. Generic versions must meet the same UK quality standards and work in the same way. Inactive ingredients and tablet appearance can differ, and generic sildenafil usually costs less than branded Viagra.

Yes, for the sildenafil tablets we supply. Our generic sildenafil 25mg, 50mg and 100mg tablets are prescription-only medicines. At Access Doctor you complete an online consultation (no separate fee), and a UK-registered prescriber issues the prescription if sildenafil is suitable. Some 50mg sildenafil products, such as Viagra Connect, are pharmacy medicines that can be bought after a pharmacist consultation without a prescription.

Both contain sildenafil. Viagra Connect is a branded 50mg tablet that is a pharmacy medicine, so it can be supplied after a pharmacist consultation without a prescription. The generic sildenafil we supply is prescription-only, comes in 25mg, 50mg and 100mg strengths, and costs less. If you need a strength other than 50mg, generic sildenafil is the option.

Most men start on 50mg. 100mg may be prescribed if 50mg works but not well enough and you have no troublesome side effects. 25mg may be used if you have mild or moderate liver problems, such as cirrhosis, or severe kidney problems, take an alpha-blocker or certain other medicines, or get side effects on 50mg. Age on its own isn’t a reason for a lower dose, and severe liver impairment means sildenafil isn’t suitable. Do not change your dose without speaking to a prescriber or pharmacist.

If your prescription is approved before 3pm (Monday to Friday), your order is dispatched the same day by tracked delivery. Your medicine arrives in plain, unmarked packaging with nothing on the outside to show what is inside.

Yes. Your GP can prescribe generic sildenafil on the NHS for erectile dysfunction after checking your general health. NHS guidance generally recommends no more than around 4 tablets a month, and local NHS policy may vary. NHS prescription charges apply in England unless you are exempt; prescriptions are free in Scotland, Wales and Northern Ireland. If you would prefer not to see your GP, an online consultation with a regulated pharmacy is an alternative.

Do not take sildenafil if you are allergic to it, use any nitrate medicine or poppers, take riociguat, have been told to avoid sex because of a heart problem, have recently had a stroke or heart attack, have very low blood pressure, have severe liver problems, have an inherited eye condition such as retinitis pigmentosa, or have lost sight in one eye from NAION. Your prescriber will also check for conditions that need caution, such as a penile deformity or Peyronie's disease, sickle cell anaemia, leukaemia or multiple myeloma, a bleeding disorder or an active stomach ulcer.

Headache is the most common side effect. Others include flushing, indigestion, a blocked nose, dizziness and changes in vision such as a coloured (often blue) tinge or blurred vision. Get emergency help if an erection lasts more than 4 hours. Stop sildenafil and get medical help immediately if you have sudden loss of vision or hearing. If you get chest pain during or after sex, stop, sit in a semi-sitting position and call 999 – do not use a GTN spray or any nitrate for the pain.

Sildenafil must never be taken with nitrates, nicorandil, poppers or riociguat. Tell your prescriber if you take an alpha-blocker such as doxazosin or tamsulosin, an HIV medicine such as ritonavir (not advised with sildenafil), or medicines such as clarithromycin, erythromycin, itraconazole or ketoconazole – you may need a lower dose. Drinking a lot of alcohol can make it harder to get an erection. Avoid grapefruit juice, which can increase side effects.

A legitimate UK online pharmacy will always ask you to complete a consultation before supplying prescription-only sildenafil, and will display its General Pharmaceutical Council registration number, which you can check on the GPhC register. Sildenafil sold without any questions, or at prices far below the usual UK range, is a warning sign – counterfeit ED medicines can contain the wrong dose or undeclared ingredients. Access Doctor's pharmacy, Pharmadocs UK Limited, is registered with the GPhC (No. 9011198).

Sildenafil 25mg starts at £8.99 for 4 tablets and 50mg at £9.99. 50mg is the standard starting dose for most men, including men aged 65 and over. 25mg is a lower dose that may be prescribed if you have severe kidney problems or mild to moderate liver problems, take an alpha-blocker or certain other medicines, or get side effects at 50mg.

Yes. The price shown covers your online consultation, review by a UK-registered prescriber, your prescription, and dispensing from our GPhC-registered pharmacy (No. 9011198). There is no separate consultation fee, prescription charge, or subscription. Delivery is free on orders over £40; below that, delivery costs £3.49

Sildenafil sold well below the typical UK range, or sold without any consultation at all, is a strong indicator of an unregulated seller. Counterfeit ED medicines are among the most commonly seized fake medicines in the UK, and have been found to contain incorrect doses, no active ingredient, or undeclared substances. See the dangers of Kamagra.

A legitimate UK pharmacy will always require a consultation before supplying prescription-only sildenafil, will display a GPhC registration number, and will name its superintendent pharmacist. Access Doctor is registered pharmacy No. 9011198, with Mr Nur Choudhury MRPharmS (GPhC 2058287) as superintendent pharmacist.

Not the generic tablets we supply. Sildenafil 25mg, 50mg and 100mg tablets are prescription-only, so no UK pharmacy can sell them without a prescription. The exception is Viagra Connect, a branded 50mg sildenafil tablet that’s a pharmacy medicine: a pharmacist can supply it after asking you some questions, in a pharmacy or online. Be wary of any website that sells sildenafil without asking about your health.

Take it about an hour before sex. In clinical studies, men who took it on an empty stomach could get an erection after about 25 minutes on average, but it usually takes 30 to 60 minutes and can take up to about 2 hours, especially after a heavy or fatty meal. It only works if you’re sexually aroused. If it doesn’t work the first time, try it on a few more occasions, and talk to your prescriber before changing the strength.

Sildenafil can help you get an erection, when you’re aroused, for around 4 to 5 hours after a dose. It doesn’t cause a continuous erection. If an erection lasts more than 4 hours, get emergency medical help, as it can cause lasting damage.

Yes. Sildenafil 25mg contains the same amount of the same active ingredient as Viagra 25mg, and the same is true of the 50mg and 100mg strengths. Branded Viagra and generic sildenafil are both prescription-only at these strengths, and generic sildenafil usually costs less.
