Viagra Connect contains sildenafil 50 mg, which helps men get and keep an erection by increasing blood flow to the penis when they are sexually aroused. It works by relaxing blood vessels and is effective for many men when taken correctly. Because it is a pharmacy medicine, we will check whether it is suitable for your symptoms and health before supply.

No. Viagra Connect is available without a prescription, but a pharmacist must assess your symptoms, health, and medicines to check it is safe for you. This helps make sure you receive the right treatment and that no medical conditions or drug interactions make sildenafil unsuitable. Other strengths still require a prescription.

Viagra Connect works best when taken about 30–60 minutes before sexual activity and you still need to be sexually aroused for it to work. Most men find it lasts around four to five hours. Its onset may be slower after a heavy meal or large amounts of alcohol, so timing and preparation can help improve reliability. 

Common side effects include headache, flushing, blocked nose and indigestion. These are usually mild and settle as the medicine wears off. Some men may notice dizziness or temporary visual changes. Rarely, severe problems such as chest pain or a prolonged erection require urgent medical attention. Always speak to a pharmacist if you are unsure.

Viagra Connect is not suitable if you take nitrate medicines, have severe heart or liver problems, very low blood pressure, or have recently had a heart attack or stroke. It is also unsuitable for certain eye conditions. A pharmacist will check your medical history and ensure it is safe before supplying the medicine.

Yes. Viagra Connect contains the same active ingredient as prescription sildenafil, but only in the 50 mg strength. Its effectiveness is similar when taken correctly, although some men may need prescription-only strengths for stronger effect. The prescriber will help determine whether Viagra Connect is appropriate for your symptoms.

Yes, but only from UK-registered online pharmacies where you complete a consultation before supply. This ensures the medicine is safe and suitable for your health. Avoid sites offering Viagra Connect without checks, as counterfeit tablets are common and potentially dangerous. Regulated pharmacies follow strict MHRA and GPhC rules.

Viagra Connect is a pharmacy medicine, meaning pharmacists must confirm it is safe and suitable before supply. They check your symptoms, medicines, heart health and any conditions that could make sildenafil unsafe. This protects you from harmful drug interactions or risk factors that may need medical review instead. It also ensures you receive appropriate advice and follow-up if the treatment doesn’t work.

No. You should never take more than one Viagra Connect tablet in 24 hours. Taking two increases the risk of side effects such as dizziness, low blood pressure and chest pain without improving results. If a single 50 mg dose isn’t effective, a prescriber may consider prescription-only strengths or alternative ED medicines.

If Viagra Connect doesn’t work, it may be due to timing, stress, meals, alcohol, or needing a different dose. Because Viagra Connect comes only in 50 mg, some men require prescription-only strengths such as 25 mg or 100 mg. A prescriber can review your symptoms, causes and treatment options if OTC sildenafil is not effective.

Some men respond well to the first dose, but others may need a few attempts before getting consistent results. Taking it correctly on an empty stomach, with sexual arousal, and without excessive alcohol helps improve effectiveness. If it doesn’t work after several tries, a prescriber can discuss alternative treatments or prescription-strength sildenafil.

The MHRA approved Viagra Connect as a pharmacy-supplied medicine only at 50 mg because this strength balances effectiveness and safety for most men. Higher or lower strengths require a prescriber to review your health and medicines. This ensures men who need more tailored dosing receive medical oversight.

Some medicines can interact with Viagra Connect, including nitrates, certain blood pressure tablets, alpha-blockers and medications that affect heart or liver function. This is why we must check your medicines before supply. Always mention everything you take, including over-the-counter and herbal products.

Viagra Connect works well for many men, but those with more severe ED or additional health problems may need prescription-only strengths or alternative ED medicines. If symptoms persist or erections remain difficult, a prescriber can assess the dose needed and recommend the most suitable treatment options.
