What is Viagra Connect?
Viagra Connect is a pharmacy medicine (P medicine) containing 50 mg of sildenafil, the same active ingredient found in prescription Viagra. It is manufactured by Viatris (formerly Pfizer’s Upjohn division) and has been available without a prescription from UK pharmacies since the MHRA reclassified it from prescription-only to pharmacy medicine status on 28 November 2017. [1]
It is available to men aged 18 and over following a consultation with a pharmacist, who assesses suitability before supplying it. It is not available without a pharmacist consultation, and it is not suitable for all men.
Viagra Connect is available only as a 50 mg tablet. Unlike prescription sildenafil, it cannot be adjusted to 25 mg or 100 mg. If a dose other than 50 mg is clinically appropriate, a prescription from a GP or other registered prescriber is required.
Our review methodology
Combining user reviews with clinical data produces a more complete picture than either source alone. The following sets out the sources used in this article and the limitations you should bear in mind when reading it.
| Source | Detail |
|---|---|
| Primary clinical data | Viagra Connect 50 mg SmPC (eMC, last updated December 2025) [2] |
| Regulatory source | MHRA reclassification press release, 28 November 2017 [1] |
| NHS information | NHS: About sildenafil [4] |
| User review platforms | Publicly available reviews on regulated pharmacy platforms and independent review aggregators, assessed October 2026 |
| Review period | Reviews published between January 2023 and October 2026 |
A note on user reviews: Online reviews of ED medicines are subject to underreporting, selection bias, and the influence of placebo effect. They cannot verify whether a medicine was used correctly, whether contraindications were present, or whether other factors contributed to outcomes. This article uses review data to identify commonly reported themes, not to make clinical recommendations. Individual experiences vary and are not a substitute for medical advice.
What the clinical evidence says about effectiveness
The SmPC for Viagra Connect 50 mg reports the following efficacy data from clinical trials. [2]
In fixed-dose studies, 74% of men taking sildenafil 50 mg reported that treatment improved their erections, compared with 25% in the placebo group.
In clinical trials where men took sildenafil 50 mg approximately one hour before sexual activity, 40.8% reported improved function after the first dose (compared with 14.6% on placebo). However, the SmPC is clear that some men only reported improvements after several attempts, with 78.4% responding by the eighth dose compared with 46.7% on placebo. [2]
The SmPC states this explicitly: patients should be advised that they may need to take Viagra Connect a number of times on different occasions before achieving a satisfactory erection. If after several attempts on different dosing occasions the medicine has not worked, they should consult a doctor. [2]
Efficacy varied by underlying cause of erectile dysfunction in clinical trial data:
- Psychogenic ED: 84% of patients reported improvement
- Mixed ED: 77%
- Organic ED: 68%
- Diabetes mellitus: 59%
- Radical prostatectomy: 43% [2]
These figures come from broader sildenafil trials rather than Viagra Connect-specific data, but as the active ingredient and dose are the same, they are directly applicable.
What user reviews commonly report
The following themes appear consistently across independent review platforms. They reflect commonly reported experiences and do not constitute clinical evidence.
What users report positively
Speed of onset: Many users report noticing effects within 30 to 60 minutes of taking the tablet. This is consistent with the SmPC, which reports that in fasted patients the median time to onset of erections of sufficient rigidity was 25 minutes (range 12 to 37 minutes).
Pharmacy convenience: The ability to access Viagra Connect following a pharmacist consultation, without a GP appointment, is consistently cited as a practical advantage, particularly for men who find discussing erectile dysfunction with their GP uncomfortable.
Reliability after initial adjustment: Reviews from men who have used Viagra Connect on multiple occasions tend to be more positive than those from first-time users, which aligns with the clinical trial data showing that response rates improve with successive use.
No prescription needed: The P medicine status is frequently mentioned as reducing a significant barrier to seeking treatment.
What users report as limitations
Food delay: The need to take the tablet on an empty stomach, or at least avoid a large fatty meal beforehand, is a commonly cited inconvenience. This is clinically significant: the SmPC reports that when taken with food, the time to maximum effect is delayed by approximately 60 minutes and the peak concentration is reduced by 29%.
No dose flexibility: The fixed 50 mg dose is cited by some men as a limitation, particularly those who find 50 mg either insufficient or associated with more pronounced side effects. Prescription sildenafil offers 25 mg and 100 mg options; Viagra Connect does not.
Cost per tablet versus generic sildenafil: Generic prescription sildenafil is considerably less expensive than Viagra Connect on a per-tablet basis. Some men report switching to prescription sildenafil once they have established that sildenafil is effective for them, for cost reasons.
Sexual stimulation still required: Some first-time users report surprise that the medicine does not produce an erection independently of arousal. The SmPC is unambiguous on this: in order for Viagra Connect to be effective, sexual stimulation is required.
Side effects: what users mention versus SmPC frequencies
The most commonly reported side effects in clinical trials across more than 9,000 patients were headache, flushing, dyspepsia (indigestion), nasal congestion, dizziness, nausea, hot flush, visual disturbance, and blurred vision. [2]
| Side effect | SmPC frequency | Commonly mentioned in reviews? |
|---|---|---|
| Headache | Very common (≥1 in 10) | Yes, frequently mentioned |
| Flushing | Common (≥1 in 100) | Yes, commonly mentioned |
| Nasal congestion | Common (≥1 in 100) | Yes, frequently mentioned |
| Dyspepsia (indigestion) | Common (≥1 in 100) | Yes, mentioned |
| Visual colour disturbance | Common (≥1 in 100) | Occasionally mentioned |
| Dizziness | Common (≥1 in 100) | Occasionally mentioned |
Most reviews that mention side effects describe them as mild and short-lived. This is consistent with the SmPC data. For a complete list of side effects and their frequencies, see our sildenafil side effects article.
Important!
Stop taking Viagra Connect and seek immediate medical attention if you experience sudden vision loss. Cases of non-arteritic anterior ischaemic optic neuropathy (NAION) have been reported rarely in connection with sildenafil. [2] Report any suspected side effects to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk. [5]
Viagra Connect versus prescription Viagra and generic sildenafil
Viagra Connect, prescription Viagra, and generic sildenafil all contain the same active ingredient at the same available dose. The differences between them are practical rather than clinical, and understanding them helps clarify when Viagra Connect is the most convenient option and when a prescription route may be more appropriate.
| Feature | Viagra Connect | Prescription Viagra | Generic sildenafil (prescription) |
|---|---|---|---|
| Active ingredient | Sildenafil | Sildenafil | Sildenafil |
| Available dose | 50 mg only | 25 mg, 50 mg, 100 mg | 25 mg, 50 mg, 100 mg |
| Prescription required | No (pharmacist consultation required) | Yes | Yes |
| Cost per tablet | Higher | Higher | Considerably lower |
| Manufacturer | Viatris | Viatris | Various |
| Regulatory category | Pharmacy medicine (P) | POM | POM |
For most men who have established that sildenafil works for them and who need dose flexibility or a lower cost per tablet, a prescription route is worth considering.
When Viagra Connect may not be the right option
The pharmacist consultation before purchase exists to identify men for whom Viagra Connect is not appropriate. The SmPC and MHRA guidance identify the following groups who should not use Viagra Connect or should consult a GP first.
Absolute contraindications:
- Men taking nitrates in any form (including nicorandil, amyl nitrite). The combination can cause a dangerous drop in blood pressure.
- Men taking ritonavir.
- Men with severe cardiovascular disorders, including recent (within 6 months) heart attack or stroke, unstable angina, or severe cardiac failure.
- Men with severe hepatic impairment, hypotension (blood pressure below 90/50 mmHg), or known hereditary degenerative retinal disorders such as retinitis pigmentosa.
- Men who have previously had vision loss in one eye due to NAION.
When a GP should be consulted first:
- Men taking alpha-blockers.
- Men with severe renal impairment.
- Men taking CYP3A4 inhibitors (such as certain antifungals or antibiotics).
- Men with mild to moderate hepatic impairment.
- Men for whom light or moderate physical activity causes breathlessness or chest pain.
When Viagra Connect has not worked:
The SmPC advises that if Viagra Connect has not worked after several attempts on different occasions, the patient should consult a GP. [2] This is clinically important: persistent erectile dysfunction that does not respond to sildenafil may reflect an underlying condition requiring medical assessment. The SmPC also recommends that all men with ED consult a doctor within six months for a review of potential underlying causes. [2]
Tips reviewers share that are consistent with the PIL
Several practical tips are frequently mentioned in user reviews. The following are consistent with guidance in the PIL and SmPC:
- Take approximately one hour before sexual activity. The SmPC confirms the recommended timing as approximately one hour before, with efficacy documented from under one hour to up to four hours post-dose.
- Avoid a large high-fat meal beforehand. A high-fat meal delays the time to maximum effect by approximately 60 minutes and reduces peak concentration.
- Sexual stimulation is necessary. Viagra Connect does not produce erections independently of arousal.
- Do not take more than one tablet in 24 hours. The maximum recommended dosing frequency is once per day.
- Avoid excessive alcohol. The PIL advises that drinking large amounts of alcohol before sexual activity can temporarily reduce the ability to get an erection.
How to access Viagra Connect through DoktorABC
Viagra Connect is available through DoktorABC following an online consultation. A UK-registered prescriber reviews your information and, if Viagra Connect is clinically appropriate, approves access. Medication is dispensed by a GPhC-registered pharmacy and delivered in discreet packaging.
See our Viagra Connect product page for details of the consultation process.
Conclusion
Viagra Connect has a well-established evidence base. The clinical trial data, drawn from studies in more than 8,000 men, show that 74% of men taking 50 mg reported improvement in erections, with response rates increasing with successive use. The most commonly reported side effects are headache, flushing, and nasal congestion, which are consistent across user reviews and clinical trial data.
The most important practical points from the clinical evidence are that the tablet works in conjunction with sexual stimulation rather than independently, that a high-fat meal can meaningfully delay its effect, and that some men require several attempts before finding it effective.
Viagra Connect is not suitable for all men, and the pharmacist consultation before purchase is a clinical safeguard, not a formality. For men who need a dose other than 50 mg, or who have not responded after several attempts at the 50 mg dose, a GP or prescriber consultation is the appropriate next step.
FAQ
Does Viagra Connect actually work?
Clinical trial data show that 74% of men taking sildenafil 50 mg reported improved erections compared to 25% on placebo. As with all medicines, individual response varies. Some men find it effective from the first dose; others need several attempts.
How long does Viagra Connect take to work?
In fasted patients, the median time to onset was 25 minutes in clinical studies, with a range of 12 to 37 minutes. Taking it with a large fatty meal can delay the effect by approximately one hour. The SmPC confirms efficacy from under one hour to up to four hours after taking the tablet.
Is Viagra Connect the same as Viagra?
Both contain sildenafil as the active ingredient. Viagra Connect is available only at 50 mg; prescription Viagra is available at 25 mg, 50 mg, and 100 mg. The clinical effect of the same dose is the same.
Can I take Viagra Connect every day?
The maximum recommended dosing frequency is once per day. It is not licensed for daily use as a regular preventive treatment in the same way that tadalafil (Cialis) is. Daily use should be discussed with a GP or prescriber.
What if Viagra Connect does not work for me?
The SmPC advises that some men only respond after several attempts. If after several doses on different occasions it has not produced a satisfactory result, a GP should be consulted. Persistent non-response may reflect an underlying health issue or suggest that a different treatment or dose may be more appropriate.
Can I take Viagra Connect with alcohol?
The PIL advises against drinking large amounts of alcohol before taking Viagra Connect, as alcohol can temporarily impair erectile function. There is no absolute prohibition on modest alcohol consumption, but excessive drinking is likely to work against the medicine’s effect.
Can I take Viagra Connect if I am on blood pressure medication?
This depends on the specific medication. Men taking nitrates must not use Viagra Connect. Men taking alpha-blockers should consult a doctor before use. Other antihypertensive medicines are generally compatible, but individual assessment is needed. Discuss with a pharmacist or GP before use.
