Tadalafil - Important Information

  • Meet Tadalafil — the generic alternative to Cialis

    If you're new to erectile dysfunction medication, you might be confused by all the different options available. Tadalafil is simply the generic version of Cialis, a popular branded erectile dysfunction treatment.

    Tadalafil generic Cialis contains exactly the same active ingredient and is just as effective as Cialis, the only difference is that it’s more affordable and widely available, since it's not a branded product.

    Like Cialis, Tadalafil also comes in a variety of strengths. Tadalafil 20mg tablets are designed for use ‘as required’, whereas Tadalafil 5mg and 2.5mg tablets (also referred to as Tadalafil Daily) are weaker forms of the medication designed for daily use, similar to Cialis Daily.

    How does Tadalafil treat erectile dysfunction?

    Tadalafil tackles erectile dysfunction by relaxing the smooth muscle in the blood vessels of the penis and increasing blood flow, helping you to achieve and maintain a healthy erection. Tadalafil starts to take effect within an hour and is effective for up to 36 hours — much longer than the 4-6 hours typically associated with Sildenafil (Viagra).

    However, it's important to note that taking a Tadalafil tablet won’t increase sexual desire — you still need to be sexually aroused for the erectile dysfunction medication to work. The treatment will only prove effective when combined with adequate sexual stimulation.

    This is because the drug Tadalafil enhances the chemical messages responsible for producing an erection; it does not, and cannot, fully replace or replicate these messages. Tadalafil also won’t give you a 36-hour erection — it simply allows you to achieve an erection through stimulation within this period.

    For more about how the drug works, visit our ‘what is Tadalafil and how does it work’ page.

    How long does Tadalafil last?

    Tadalafil offers a significant advantage over other erectile dysfunction treatments due to its longer-lasting effects. While other medications usually remain effective for just a few hours, Tadalafil can continue to treat erectile dysfunction for up to 36 hours.

    Tadalafil’s extended period of effectiveness provides users with greater freedom and spontaneity in sexual activity, eliminating the need to precisely time dosages in advance. As a result, Tadalafil enables users to enjoy more flexible and natural sexual experiences.

    What causes erectile dysfunction (ED)?

    There can be many different causes of ED, including:

    • Physical causes: Many physical conditions can contribute to ED, including cardiovascular disease, diabetes, high blood pressure, high cholesterol, obesity, low testosterone levels, and Parkinson's disease.
    • Psychological causes: Psychological factors can also play a role in ED, including stress, anxiety, depression, and relationship problems.
    • Medications: Certain medications, such as those used to treat high blood pressure, depression, and anxiety, can cause ED as a side effect.
    • Lifestyle factors: Unhealthy lifestyle choices, such as smoking, excessive alcohol consumption, and drug use, can contribute to ED.
    • Neurological conditions: Neurological disorders such as multiple sclerosis, spinal cord injuries, and stroke can cause ED.
    • Hormonal imbalances: An imbalance of hormones such as testosterone, prolactin, and thyroid hormones can contribute to ED.
    • Peyronie's disease: This is a condition in which scar tissue forms inside the penis, causing it to curve and leading to ED.
    • Age: As men age, the risk of developing ED increases, although it is not an inevitable part of ageing.

    You can find out more here on our ED causes page.

    What other erectile dysfunction treatments are available?

    In addition to generic Cialis/Tadalafil tablets, there are several alternative erectile dysfunction medications that you can purchase online from The Independent Pharmacy. These are:

    Tadalafil is very similar to sildenafil (Viagra) and other ED treatments in effectiveness, however, it lasts much longer, making it a better option for weekend use. No combination of Viagra/Sildenafil, Cialis, Levitra, Spedra or other erectile dysfunction treatment should be used at the same time — you should leave a break of at least 24 hours (36 hours for Cialis/generic Cialis Tadalafil).

    You may also consider a non-prescription treatment for erectile dysfunction, such as making lifestyle changes to address the issue. These include:

    • Changes to your diet (such as reducing your alcohol and fat consumption)
    • Counselling (to address symptoms of anxiety or depression)
    • Lowering your stress levels (doing exercises such as yoga)
    • Stopping smoking
    • Using a vacuum device (penis pump)

    Should I buy Tadalafil or Sildenafil?

    Tadalafil and Sildenafil are two of the most popular ED medications, and deciding between them can be challenging. Here's a breakdown of the key differences between the two to help you make an informed decision.

    • Duration of action: Tadalafil is known for its long duration of action, which can last up to 36 hours. This extended period of effectiveness allows for more spontaneity in sexual activity, as users don't need to plan their medication intake as precisely as with other medications. On the other hand, Sildenafil typically lasts for 4-6 hours, which may be sufficient for some users.
    • Onset of action: Sildenafil is known to take effect faster than Tadalafil, with some users experiencing results in as little as 30 minutes. Tadalafil, on the other hand, typically takes an hour or more to take effect.
    • Cost: Generic Tadalafil is often more affordable than branded Cialis, while generic Sildenafil is usually cheaper than branded Viagra. However, the cost may vary depending on the specific brand and dosage.

    Ultimately, the decision to buy Tadalafil or Sildenafil depends on your individual needs and preferences.

    If you value flexibility and spontaneity in sexual activity, Tadalafil may be the better choice due to its longer duration of action. If you're looking for a medication that takes effect quickly, Sildenafil may be the better option.

  • How to take Tadalafil 20mg tablets

    The maximum dose of Tadalafil is one 20mg tablet per day. Do not repeat the dose or take any other ED treatments within 36 hours of your initial dose.

    Tadalafil 20mg tablets are designed to be taken on an ‘as required' basis — only take them if you expect that you’re going to need help achieving an erection within the next 36 hours.

    Tadalafil tablets may be taken either with or without food. Swallow the tablet whole and if needed, use water to wash it down.

    Always avoid or limit the use of alcohol while using Tadalafil.

  • Which strength of Tadalafil should I choose?

    Tadalafil tablets are available in a variety of different strengths. The strength you choose will depend on how you want to use it — the two main ways to take Tadalafil are as an ‘as required’ dosage or as a continuous daily dosage.

    • Tadalafil 10mg & 20mg (the ‘as required’ dose) — the recommended starting dose for Tadalafil as an ‘as required’ medication is 10mg, taken at least 30 minutes before sexual activity. From there, the dose may be increased to 20mg or decreased to 5mg, depending on how your body reacts. It's important to note that Tadalafil should not be taken more than once per day.

    Tadalafil's 10mg and 20mg strengths are formulated for occasional use and can remain active for up to 36 hours, making them an excellent choice if you engage in sexual activity less than twice a week or cannot predict when you'll next have sex. These strengths provide you with the flexibility to achieve an erection only when you need it, without requiring daily medication.

    • Tadalafil 2.5mg & 5mg (Tadalafil Daily) — For individuals who engage in sexual activity more frequently or want to be ready at all times, Tadalafil is also available as a continuous daily medication.

    The recommended starting dose for daily Tadalafil is 2.5mg, which can be increased to 5mg based on the individual's response. This method of dosing is ideal for individuals who have sex at least twice a week and want to be able to achieve an erection at any time.

  • Tadalafil tablets contain: 10mg or 20mg (depending on the strength) of Tadalafil as the active ingredient.


    The inactive ingredients contained in Tadalafil tablets are: Lactose monohydrate, croscarmellose sodium, hydroxypropyl cellulose, sodium lauryl sulphate, microcrystalline cellulose, magnesium stearate.

  • Tadalafil side effects

    Tadalafil is generally well-tolerated, but like any medication, it can cause side effects in some people. Here are some potential side effects to be aware of when taking Tadalafil:

    • Headache
    • Flushing
    • Back pain
    • Muscle aches
    • Nasal congestion
    • Indigestion or stomach upset
    • Diarrhoea
    • Dizziness or lightheadedness
    • Blurred vision or changes in colour vision
    • Sudden loss of hearing or ringing in the ears
    • Priapism (a prolonged and painful erection that lasts longer than 4 hours)
    • Allergic reactions, including rash, hives, or swelling of the face, lips, tongue, or throat

    If you experience any of these side effects while taking Tadalafil tablets to treat erectile dysfunction, it's important to contact your local GP or pharmacist. In some cases, they may recommend adjusting your dosage or switching to a different medication.

    In rare cases, Tadalafil can cause serious side effects such as low blood pressure or vision loss, which require immediate medical attention.

  • Tadalafil (10mg & 20mg) warnings

    Please read the following warnings carefully:

    • Tadalafil should only be taken as prescribed by a healthcare professional.
    • Tadalafil is not intended for use in women or children.
    • Tadalafil should not be taken if you're taking medications containing nitrates or if you have a history of cardiovascular disease or other heart problems.
    • You should not take Tadalafil if you have a history of allergic reactions to Tadalafil or other PDE5 inhibitors.
    • Tadalafil can cause dizziness and affect your ability to drive or operate heavy machinery.
    • Tadalafil tablets may interact with certain medications, including alpha-blockers, and can cause a sudden drop in blood pressure.
    • If you experience an erection that lasts longer than 4 hours, seek immediate medical attention to prevent damage to the penis.
    • Tadalafil tablets should not be taken with grapefruit or grapefruit juice as it can increase the risk of side effects.
    • If you experience sudden vision loss or changes in vision, stop taking Tadalafil and seek medical attention immediately.

    It's important to talk to your GP or pharmacist if you have any concerns about using Tadalafil, or if you experience any side effects. They can help determine if Tadalafil is right for you and recommend appropriate treatment options. For a full list of warnings and side effects, please refer to the Tadalafil Patient Information Leaflet.

    Tadalafil drug interactions

    Tadalafil may interact with other drugs, and some of these interactions can be harmful. These include:

    • Nitrates: Taking Tadalafil with nitrates, such as nitroglycerin, can cause a sudden and dangerous drop in blood pressure.
    • Alpha-blockers: Tadalafil may increase the effects of alpha-blockers, such as doxazosin and terazosin, which are used to treat high blood pressure and prostate enlargement.
    • Antihypertensive drugs: Tadalafil can enhance the effects of antihypertensive drugs, leading to a significant drop in blood pressure.
    • Antibiotics: Tadalafil can interact with certain antibiotics, such as clarithromycin and erythromycin, leading to increased levels of Tadalafil in the blood.
    • Antifungal drugs: Tadalafil can also interact with some antifungal drugs, such as ketoconazole and itraconazole, leading to increased levels of Tadalafil in the blood.
    • HIV protease inhibitors: Tadalafil can interact with some HIV protease inhibitors, such as ritonavir and saquinavir, leading to increased levels of Tadalafil in the blood.
    • Grapefruit juice: Grapefruit juice can increase the levels of Tadalafil in the blood, leading to an increased risk of side effects.
  • What does 20mg of Tadalafil do?

    A 20mg dose typically takes effect within an hour of ingestion and helps you to achieve and maintain an erection by improving blood flow to the penis. The effects of Tadalafil 20mg will last for up to 36 hours.

    Can I order Tadalafil online?

    Yes, you can order Tadalafil online through The Independent Pharmacy, subject to an online consultation with one of our qualified healthcare professionals. The consultation is a simple and secure process that involves answering a few questions about your health and medical history to ensure that Tadalafil is a safe and effective treatment option for you.

    How many hours does 20mg of Tadalafil last?

    Tadalafil 20mg tablets remain active in the body for up to 36 hours, making them ideal for use on an ‘as required’ basis. This does not mean that you’ll have an erection for 36 hours; it simply means that you’ll be able to achieve and maintain an erection when sexually aroused during this period.

    Is Tadalafil safe?

    Tadalafil was approved for the treatment of erectile dysfunction in 2003, and is considered safe to use by most people. However, there are certain circumstances where you should not take Tadalafil. These include:

    • If you are allergic to any of the ingredients listed.
    • If you have low blood pressure.
    • If you have heart, liver, or kidney problems.
    • If you are taking medication containing nitrates.
    • If you are taking medication for your heart, or for the treatment of epilepsy.
    • If you have ever suffered a heart attack or a stroke.

    Bear in mind that this list is not exhaustive. See the Patient Information Leaflet for full details.

    When is the best time to take Tadalafil 20mg?

    It is recommended that you take 1 tablet at least 30 minutes before you intend to have sex. Tadalafil may take up to 1 hour to fully take effect, but after this its effects will last for up to 36 hours. Never take more than one tablet in a day.

Tadalafil Tablets (10mg & 20mg) FAQs

  • A GP needs to assess the suitability of this ED treatment before it can be prescribed for you.

    They will check your medical history and other medications that you’re on. Tadalafil is a widely prescribed treatment, but it can be unsuitable for some men. Your doctor will tell you more.

    If you buy Tadalafil online from The Independent Pharmacy, we take care of the prescription for you, our doctors will send it straight to our pharmacy to send out to you the same day.

  • Among the available ED medication, Tadalafil is known as ‘the weekend pill’. This is because once you have taken a dosage, the drug remains active for 36 hours.

    Most of the other major ED tablet medication on the market (such as Viagra) remain active for four to six hours. Topical agents and urethral suppositories begin working within minutes, but they remain effective for between one and two hours.

    Another advantage of Tadalafil is that it gives you the option to be spontaneous – Tadalafil takes 30-60 minutes to take effect once administered, and no prior dosage is required.

  • Tadalafil will be effective for up to 36 hours. However, this doesn’t mean that you will have an erection for the duration of this time, as sexual stimulation is required in order for you to achieve an erection while taking Tadalafil.

  • Tadalafil has a similar rate of success to Sildenafil (this drug is sold under the brand name Viagra, among others, and is perhaps the most established drug on the market for ED).

  • Both Tadalafil and Viagra are effective treatments for ED. However, as outlined above, the effects of Tadalafil last longer than Viagra.

  • There are two strengths of Tadalafil tablets available: 10mg and 20mg.

    We recommend that men trying Tadalafil tablets for the first time start with 10mg and can then move to the higher dose if necessary.

  • It is recommended that you begin by taking a lower strength tablet and build up as needed.

    One type of tablet may work better than another and you should always consult your doctor before you begin your course of medication.

  • You should only take Tadalafil if you are experiencing ED and should not take it for the purpose of sexual enhancement.

  • You are able to, but this depends on the type of medications you are taking.

    Your doctor will review your medical history when prescribing Tadalafil, which will include any past or current medications you are using.

    Your doctor will check for any interactions between Tadalafil and your medications and advise you accordingly on whether your past or current medication restricts you from taking Tadalafil.

  • Grapefruit juice should be avoided if you are taking Tadalafil.

    Grapefruit juice can affect how your system metabolises medicine, and this means that drinking it while taking Tadalafil may increase your sensitivity to side effects of taking the medication.

  • If you do not see an improvement in your ability to achieve and maintain an erection while taking Tadalafil, then you should speak with your doctor.

    Your doctor may then change the dosage of Tadalafil you are taking, or refer you to a different form of ED medication.

  • Yes, but you will have to undertake a short medical consultation with an online doctor first, as Tadalafil is only available on prescription in the UK. Always buy from a reputable, registered pharmacy.

  • 20 mg is the maximum dosage of Tadalafil, and this should never be exceeded. Rather than taking two 10 mg tablets, it’s recommended that you switch over to higher dosage 20mg ones. Taking more Tadalafil will not help you get a better erection, but it could cause dangerous side effects.

  • Tadalafil takes about thirty minutes to have an effect, and then it stays active in the body for up to 36 hours. Remember that Tadalafil only works to produce an erection when you are sufficiently sexually stimulated — it cannot produce an erection on its own.

  • As with all prescription medications, it’s important that you check with the doctor before starting your course of treatment to ensure that it’s the right one for you. There are some people who should not take ED medication. Tadalafil is just as safe and effective as the branded Cialis, which is a hugely popular ED treatment.

  • Yes, but it’s only safe in small quantities. Overdoing it with alcohol while on Tadalafil could lead to an increase in side effects and also makes ED worse.
