Erectile Dysfunction

Erectile dysfunction (ED) is very common and can affect men of any age, but several effective treatments can help. Most ED medications are tablets that improve blood flow to the penis, but there are also effective creams, injections, and devices. The right treatment depends on how quickly you want it to work, how long you need the effect to last, how often you have sex, and your medical history.

QuickMeds offers several erectile dysfunction treatments, including Viagra (sildenafil), Cialis (tadalafil), vardenafil and avanafil. Most ED medicines are prescription-only, so a prescriber will check which options are suitable for you before treatment is supplied

Frequently Asked Questions

Everything you need to know

Can I cut ED treatment tablets in half?
+−

Do not cut an erectile dysfunction tablet in half unless your prescriber or pharmacist has confirmed that your specific tablet can be split safely. If your current dose does not suit you and you want to move to a lower strength tablet, speak to us rather than adjusting it yourself.

What should I do if the Erectile Dysfunction medications I took don't work?
+−

When you initially start taking the medication, your doctor will prescribe the medium dosage. It is important to trial the drug at least four times before deciding it doesn’t work for you. If this is the case, your doctor may suggest a higher dose or an alternative medication. If the initial dose was more effective than anticipated, you can try a lower dosage. 

It is important to remember that eating a heavy meal or consuming excessive amounts of alcohol can impair the drug's effectiveness. Always seek the advice of your doctor before taking prescription medication and read the safety information and instructions provided with it.

What are the side effects of ED tablets?
+−

The most common side effects are headache, flushing, indigestion, a blocked or runny nose and dizziness. Tadalafil can also cause back or muscle pain. They are usually mild and wear off as the medicine does. Get urgent medical help if you have chest pain, sudden loss of vision or hearing, or an erection lasting more than four hours. ED tablets must never be taken with nitrates (often prescribed for angina) or “poppers”. The full list of side effects for each medicine is on its product page and in its patient information leaflet.

Is Erectile Dysfunction linked to premature ejaculation?
+−

Erectile dysfunction and premature ejaculation are separate conditions, though some men experience both. ED is difficulty getting or keeping an erection, while premature ejaculation is ejaculating sooner than wanted. Premature ejaculation has different treatments from erectile dysfunction, so it helps to mention both to a prescriber if they affect you.

Is it safe to buy ED medication online?
+−

Yes, it is safe when you buy erectile dysfunction medication online from a pharmacy registered with the General Pharmaceutical Council (GPhC) that requires a consultation and prescriber review. Avoid websites that sell prescription ED tablets with no questions asked, as these may supply fake or unsafe products.

Quick Meds is registered with the GPhC (you can find our regulatory information below) and is also an NHS registered pharmacy providing services to NHS patients.

Where can I buy erectile dysfunction medication online in the UK?
+−

You can request ED medication online from Quick Meds, a GPhC-registered pharmacy. After a short online consultation and a phone call with one of our prescribers, we check that a treatment is suitable, and eligible patients have it delivered discreetly. Buying from a GPhC-registered pharmacy is important, as it means the medicine is genuine and prescribed safely.

What are the alternatives to ED tablets?
+−

If tablets are not suitable or do not work, other options include Eroxon gel, which is applied to the tip of the penis, works within about 10 minutes and does not need a prescription; alprostadil cream (Vitaros), applied to the opening at the tip of the penis; and alprostadil injections (Viridal Duo). Vacuum pumps and, where stress or relationship factors play a part, psychosexual therapy can also help. A prescriber can advise which option suits you.

Can Erectile Dysfunction be cured?
+−

Erectile dysfunction can sometimes be cured if the underlying cause can be treated, such as a lifestyle factor or an underlying condition. In other cases, ED is ongoing and managed effectively with medication and lifestyle changes rather than cured outright. Stopping smoking, cutting down on alcohol, staying active and keeping a healthy weight all lower your risk.

Is erectile dysfunction normal at my age?
+−

ED becomes more common with age, especially after 40, and about half of men aged 40 to 70 have some degree of it. It is not an inevitable part of getting older, though, and it can affect men of any age. In younger men it is more often linked to stress, anxiety or lifestyle; in older men, to conditions such as heart disease, high blood pressure or diabetes. Because ED can be an early sign of heart disease, it is worth getting checked at any age.

Is erectile dysfunction the same as impotence?
+−

Yes, impotence is an older word for erectile dysfunction (ED). Both describe difficulty getting or keeping an erection firm enough for sex. Erectile dysfunction is the term more commonly used by healthcare professionals today and covers erection problems that happen occasionally as well as those that happen regularly.

Will I have to take ED medication for the rest of my life?
+−

If the cause of your erectile dysfunction can be treated or improves with lifestyle changes, you may not need ED medication long term. In other cases, ongoing treatment is the most effective way to manage it. A prescriber will review your treatment over time.

Will I become addicted to ED medication?
+−

No, ED medications, including tablets like sildenafil and alprostadil creams or injections, are not addictive. Needing a medication to get an erection is not a sign of dependence; it simply means the medicine is helping with a physical process. You take it only when you need it, or as a low daily dose if that option suits you.

What should I do if my erection lasts more than four hours?
+−

An erection lasting more than four hours (priapism) is a medical emergency. Seek urgent medical help straight away, as prompt treatment protects against lasting damage. This is rare, but it is important to act quickly if it happens.

Which erectile dysfunction medication is best?
+−

There is no single ED medication that is best for everyone. The right treatment depends on how often you have sex, whether you prefer daily or on-demand treatment, your medical history and any other medicines you take. Creams and injections are also available if ED tablets are not suitable. If you're unsure of which treatment is best for you, get in touch with our team and a prescriber will help you choose a suitable ED treatment during your consultation.

How long should I wait between ED treatment doses?
+−

How long you should wait between ED treatment doses depends on the medicine you take, so follow the dosing instructions supplied with your treatment. As a general rule, on-demand tablets are taken no more than once in 24 hours. Daily tadalafil is taken once a day at around the same time. Check with a pharmacist if you are unsure.

How long do ED tablets take to work and how long do they last?
+−

Most erectile dysfunction tablets start working within 30 to 60 minutes, although avanafil can work in as little as 15 to 30 minutes. Sildenafil and vardenafil work for around 4 to 5 hours, avanafil for up to about 6 hours, and tadalafil for up to 36 hours. You won’t have an erection throughout this time: you still need sexual stimulation to get one.

Can I buy ED tablets over the counter, or without seeing a doctor?
+−

Yes, you can buy ED tablets over the counter. Viagra Connect (sildenafil 50mg) is available alongside Cialis Together (tadalafil 10mg) following a short consultation with us.

What causes erectile dysfunction?
+−

ED can have physical or psychological causes, and often a mix of both. Physical causes include conditions that affect blood flow, such as heart disease, high blood pressure, high cholesterol and diabetes. Others are low testosterone, some medicines (including some blood pressure tablets and antidepressants), smoking, heavy drinking and being overweight. Psychological causes include stress, anxiety, depression and relationship problems. Our prescribers check for these during your consultation.

How much does ED treatment cost?
+−

It depends on the medicine, strength and pack size. At Quick Meds, tadalafil starts at 4 tablets for £8.95, sildenafil from £1.25 a tablet, and daily tadalafil from £0.62 a tablet. Tracked delivery is from £5.99. There’s no subscription: you only order when you need to.

Can I drink alcohol while taking ED tablets?
+−

A small amount of alcohol is usually fine, but heavy drinking makes erection problems worse and can increase side effects such as dizziness and low blood pressure. Keep alcohol to a minimum around the time you take your tablet and follow the advice in your patient information leaflet.

Types of erectile dysfunction medications

Erectile dysfunction medications are typically in the form of a tablet. Other options such as alprostadil and vacuum pumps are available when tablets are unsuitable or don't work.

Erectile dysfunction pills

The main ED tablets belong to a group of medicines called PDE5 inhibitors. PDE5 inhibitors increase blood flow to the penis, making it easier to get and keep an erection when sexually stimulated. They do not cause an erection automatically, so you still need to be sexually aroused for them to work.

There are four main PDE5 inhibitors, each available as a branded and a lower-cost generic version:

  • Sildenafil, the active ingredient in Viagra

  • Tadalafil, the active ingredient in Cialis

  • Vardenafil, the active ingredient in Levitra

  • Avanafil, the active ingredient in Spedra

Although these medicines work in a similar way, there are practical differences between them, including how quickly they start working, how long their effects can last, how food affects them and the doses available.

Some ED tablets can be supplied without a prescription following a pharmacist suitability check. These include Viagra Connect, Viagra Connect Melts, Aronix Tablets, Eropid Tablets, which all contain 50mg of sildenafil, and Avarante and Cialis Together, which contain 10mg tadalafil.

Other oral ED treatments at Quick Meds require a prescription and clinical assessment.

Daily and on-demand ED treatment

Most ED tablets are taken when needed before sex, but tadalafil is also available as a lower-dose daily treatment on prescription only.

  • On-demand ED tablets are taken before you plan to have sex. Sildenafil, vardenafil and avanafil are taken this way, while tadalafil can be used either on demand or daily.

  • Daily tadalafil is taken once a day, whether or not you plan to have sex, to provide ongoing effects. It may suit you if you have sex regularly or prefer more spontaneity.

Your prescriber can help you decide whether on-demand or daily treatment is more suitable based on your preferences, how often you have sex and your medical history.

Other erectile dysfunction treatments

If PDE5 inhibitor tablets are not suitable or don’t work well enough, other ED treatments include alprostadil medicines and vacuum pumps.

  • Alprostadil increases blood flow to the penis and is available in two forms. Vitaros is a cream applied to the opening of the penis, while Viridal Duo is given as an injection into the penis.

  • Vacuum pumps are placed over the penis to draw blood into it and create an erection. A constriction ring is then placed around the base of the penis to help maintain the erection.

A healthcare professional can help you decide which type of ED treatment may be suitable for you.

What is erectile dysfunction?

Erectile dysfunction, also called impotence, is the difficulty getting or keeping an erection firm enough for sex. For some men, erectile dysfunction happens occasionally, often linked to tiredness, stress, or alcohol. For others, it is an ongoing problem.

Occasional difficulty is normal and not usually a concern, but if ED keeps happening, it is worth looking into the cause, because it can point to an underlying health condition.

Erectile dysfunction symptoms

The main erectile dysfunction symptom is the inability to get or maintain an erection for sex. This can range from:

  • Being unable to get an erection at all

  • Getting an erection that is not firm enough

  • Losing an erection before or during sex

Whether erections happen at other times can sometimes give a clue about the cause, but it cannot diagnose the cause on its own.

What causes erectile dysfunction?

Erectile dysfunction can have both physical and psychological causes – and sometimes a combination of the two.

Physical causes of ED include conditions that affect blood flow, nerves or hormone levels, such as:

  • High blood pressure

  • High cholesterol

  • Diabetes

  • Hormonal problems, including low testosterone

  • Being overweight

  • Smoking

Some medicines can also cause or contribute to erection problems.

Psychological causes include stress, anxiety, depression, relationship difficulties and anxiety about sex itself. These factors can affect erections even when there is no underlying physical problem that is stopping you from getting an erection.

If ED keeps happening, it is worth speaking to a healthcare professional. Erectile dysfunction can sometimes be associated with conditions affecting cardiovascular health. It’s worth getting recurring symptoms assessed rather than simply treating the erection problem.

Which erectile dysfunction treatment may be suitable for you?

There is no single erectile dysfunction medicine that is right for everyone. The table below can help you understand the practical differences to guide you towards which treatment you want to request.

It is not a substitute for a clinical assessment. The final choice is made with a prescriber.

Comparing the main erectile dysfunction pills

ED pills differ in how quickly they work, how long their effects last, how they are taken and whether or not they require a prescription.

Your prescriber will recommend a suitable starting dose based on the ED medicine you choose, your health and any other medicines you take. It can sometimes take more than one attempt to find out how well a treatment works for you.

If one tablet does not work well or causes side effects, a prescriber may suggest increasing or reducing the dose, or trying another treatment.

Who shouldn’t take ED medications?

Not every erectile dysfunction treatment is suitable for everyone. Which treatments you can use depends on your health, other medicines you take and the type of ED treatment.

  • ED tablets must not be taken with nitrate medicines used for chest pain because this can cause a dangerous drop in blood pressure. They may also be unsuitable if you have certain heart or blood pressure conditions or have recently had a heart attack or stroke.

  • ED creams and injections containing alprostadil may not be suitable if you have certain conditions that increase your risk of prolonged erections, such as sickle cell disease or leukaemia. Some conditions affecting the penis may also make these treatments unsuitable.

Tell your prescriber about any health conditions you have and all medicines you take so they can check which ED treatments are safe and suitable for you.

Do erectile dysfunction medications have side effects?

Like all medicines, erectile dysfunction treatments can cause side effects.

PDE5 inhibitor tablets such as sildenafil and tadalafil commonly cause:

  • Headache

  • Facial flushing

  • Blocked or runny nose

  • Indigestion

  • Dizziness

Depending on the specific medicine, some ED tablets can also cause other side effects. For example, sildenafil can cause changes to vision, while tadalafil can cause back pain and muscle aches.

Alprostadil creams and injections are more likely to cause side effects around the penis, such as penile pain, burning or irritation. Alprostadil injections can also cause bruising or bleeding where the medicine is injected.

All ED medicines can rarely cause a prolonged erection (priapism). Get urgent medical help if you have an erection lasting four hours or longer, as it can cause permanent damage if left untreated.

Always read the patient information leaflet supplied with your medicine for a full list of side effects.

Lifestyle changes that support erectile function

ED medication treats the symptom, but tackling the causes often improves ED and your wider health at the same time. Helpful changes include:

  • Keeping to a healthy weight and eating a balanced diet lower in fatty and salty foods.

  • Staying physically active, which supports blood flow and heart health.

  • Stopping smoking, which damages blood vessels.

  • Cutting down on alcohol and avoiding recreational drugs.

  • Managing stress and mental wellbeing, since anxiety and low mood can contribute to ED

Because ED can signal an underlying condition, it is also worth having any high blood pressure, cholesterol, or blood sugar checked and treated.
