Medicine interactions
Nitrates and some blood-pressure medicines can't be combined with ED tablets. We check every one.
When to see your GP
If your answers suggest an underlying cause, your doctor recommends the right tests near you.
How do ED treatments work?
Here's what happens in your body to get the blood flowing again.
Stimulation increases blood flow
Arousal triggers a molecule (cGMP) that relaxes blood vessels and lets blood flow in.
Limited blood flow stops an erection
With ED, an enzyme called PDE5 breaks cGMP down too quickly.
Medication supports a firmer erection
PDE5 inhibitors block that enzyme, so the effect lasts longer, with arousal.

Erection problems and treatment
Erectile dysfunction means regularly finding it hard to get or keep an erection firm enough for sex. It is common and often linked to blood flow, blood pressure, diabetes, medicines, stress or a mix of these. A doctor may consider one of four tablets (sildenafil, tadalafil, vardenafil or avanafil), which help an erection happen when you are sexually aroused. For men who cannot take tablets or do not respond to them, alprostadil cream applied to the penis is another option. The doctor chooses based on your health, your medicines and how you prefer to plan sex.
Who can be treated online
The online assessment is for adult men with ongoing erection problems who are otherwise well enough to be sexually active. It is not suitable if you take nitrate medicines or use poppers, have had a recent heart attack or stroke, get chest pain on exertion or during sex, or have very low blood pressure. Erection problems that start suddenly after an injury, pain or a new bend in the penis, or signs of low testosterone need an in-person examination. The questionnaire checks these points, and the doctor tells you before you pay if you need to be seen.
Side effects and warning signs
The most common side effects of erection tablets are headache, flushing, indigestion and a blocked nose, and tadalafil can also cause back or muscle pain. Taken with nitrates or poppers they can cause a dangerous drop in blood pressure, and some blood-pressure and prostate medicines need extra care. Alprostadil cream can cause local burning or redness, and a condom is needed if your partner is pregnant or could become pregnant. Get urgent help, or call 112, for an erection lasting more than four hours, chest pain, or sudden loss of vision or hearing.
Other ways to improve erections
Losing weight if needed, regular aerobic exercise, stopping smoking and drinking less alcohol can improve erections and heart health at the same time. Talking therapy or couples counselling helps when stress, anxiety or relationship issues play a part. If treatment does not work or does not suit you, a urologist can offer other options in person, such as vacuum devices, injections into the penis or, rarely, surgery. If the doctor decides treatment is not appropriate, they explain why and suggest the right check with your family doctor.
What the research shows
Sildenafil has been authorised in the EU since 1998, and tadalafil, vardenafil and avanafil followed. In the fixed-dose studies summarised by the European Medicines Agency, between 62 and 82 per cent of men taking sildenafil reported improved erections, depending on the dose, compared with 25 per cent on placebo. The European Association of Urology recommends these tablets as first-line treatment, together with lifestyle changes and an assessment of heart risk. Erection problems can be an early sign of heart disease, which is why the doctor looks at your cardiovascular history.
Your erectile dysfunction consultation
You answer a questionnaire about your erections, heart health, blood pressure, other conditions and every medicine you take, including recreational drugs such as poppers. No photos or video call are needed. An EU-licensed doctor reviews your answers, may ask questions in the private chat and, if appropriate, prescribes the option that suits you with clear instructions. You collect and pay for the medicine at a pharmacy of your choice in the EU, where the pharmacist may dispense the locally marketed version of the same active ingredient.
Reviews and ongoing treatment
Erection tablets are taken when needed, and it can take a few attempts to find the dose and timing that work for you. Message your doctor if the treatment does not work well, causes side effects, or your health or medicines change. Repeat prescriptions go through a new consultation, so the doctor can recheck your heart health and medicines. It is also worth having your blood pressure, blood sugar and cholesterol checked by your family doctor, as they affect both erections and the heart.
