Cialis - Key Information

Tadalafil, often sold under the brand name Cialis, is a medication used to treat erectile dysfunction (ED) in men.

  • It is sometimes called the "weekend pill" because it works for up to 36 hours, much longer than other ED treatments.
  • This extended duration allows you to take it and be ready for sexual activity at any time during that period, offering more flexibility.
  • Tadalafil is the generic version of Cialis, making it a more affordable option with the same effectiveness.

If you think Tadalafil might be right for you, consult your doctor or pharmacist to ensure it

Yes, the generic version of Cialis is tadalafil. Cialis lost its exclusive patent in the UK in November 2017, making tadalafil tablets widely available as a more affordable option.

  • Cialis is the brand name, while tadalafil is the active ingredient.
  • Both versions are equally effective, but branded Cialis typically costs more due to its name and marketing.

Key Similarities:

  • Both contain the same active ingredient and work in the same way.
  • They have the same effectiveness and potential side effects.

Main Difference:

  • Price: Tadalafil (generic) is typically much more affordable than branded Cialis, making it a cost-effective option.

If cost is a concern, talk to your doctor or pharmacist about switching to Tadalafil for the same benefits at a lower price.

Cialis UK

UK Meds offers both:

If you need a prescription, UK Meds provides an online consultation service with an independent prescriber to ensure the medication is suitable for you.

For personalised advice, always consult your doctor or pharmacist.

How does Cialis work?

Cialis contains tadalafil, which helps treat erectile dysfunction (ED) by temporarily increasing blood flow to the penis. This makes it easier to achieve and maintain a firmer, longer-lasting erection when you’re sexually aroused.

Important to know:

  • Cialis doesn’t increase sexual desire. If you’re experiencing low libido, speak to your doctor or pharmacist for advice on suitable treatments.

How effective is Cialis?

Cialis is a highly effective and long-lasting treatment for erectile dysfunction (ED).

  • Studies show that over 80% of men taking Cialis were able to achieve erections firm enough for sex (Skoumal et al., 2004).
  • Its effects can last up to 36 hours, providing flexibility and confidence for men managing ED.
  • Tadalafil may not work immediately for everyone. You should try it at least eight times before considering other options.
  • Elderly patients and those with diabetes typically do not need a dose adjustment for Tadalafil.
  • It is unclear how effective Tadalafil is for people who have had pelvic surgery or prostate removal.

Cialis is a trusted choice for many. If you’re considering it, speak to your doctor to ensure it’s the right treatment for you.

What experiences have Cialis users had?

Cialis Reviews

Cialis has helped many men manage erectile dysfunction (ED), with customer reviews highlighting its positive impact.

  • First-hand reviews: Read feedback from other UK Meds customers about how Cialis has worked for them.
  • More reviews available: Explore additional insights on websites like Drugs.com and WebMD.

Is Cialis right for me?

People's experiences with Cialis can vary, and what works for one person might not work for another.

  • If you’re considering Cialis, it’s important to:
    1. Consult your doctor or healthcare provider to ensure it’s safe and suitable for your needs.
    2. Base your decision on your own experience, as recommended by your doctor.

For more information on the prescription medication patients should refer to the Cialis (Tadalafil) patient information leaflet.

Usage Advice

  • Tadalafil is available in four strengths: 2.5mg, 5mg, 10mg, and 20mg.

    • Occasional use: Most men take a 10mg or 20mg tablet as needed.
    • Daily use: The 2.5mg and 5mg doses are designed for daily use, allowing spontaneous sexual activity.
    • Some men may find an occasional 5mg tablet is sufficient.

    Tips for First-Time Use

    Tadalafil might not work the first time. It’s recommended to try it at least eight times before considering other options.

    How to Take Tadalafil:

    1. Start with 10mg: Take one tablet 30 minutes before sexual activity.
    2. Sexual arousal required: Tadalafil only works when you’re sexually excited.
    3. With or without food: You can take it with meals, but swallow it with water.
    4. No mixing with other ED treatments: Do not take Tadalafil within 24 hours of other erectile dysfunction medications.

    If you’re unsure about the correct dosage or usage, consult your doctor or pharmacist for personalised advice. Always follow professional guidance to ensure safe and effective results.

Cialis usually takes about 30 minutes to start working, but it only becomes effective with sexual stimulation.

  • Once active, its effects can last for up to 36 hours, earning it the nickname “the weekend pill.”

How long should I take Cialis for?

You can take Cialis for as long as your doctor prescribes it.

  • Research has not shown any negative effects from long-term use of Cialis.
  • Cialis should be used only when needed, taken before sexual activity.

Dosage

Cialis (tadalafil) comes in four dosage options: 2.5mg, 5mg, 10mg, and 20mg. The right dose depends on how often you need it and your doctor’s recommendation.

Dosage options

Cialis Daily (For regular use):

  • 2.5mg: A lower-strength option. Ideal if 5mg worked but caused mild side effects.
  • 5mg: The standard daily dose, suitable if you have sex more than twice a week.

Cialis as needed (taken before sex):

  • 10mg: The usual starting dose for first-time users.
  • 20mg: A stronger option if 10mg isn’t effective and you experience no serious side effects.

For personalised advice, speak to your healthcare provider to find the best dosage for you.

Side Effects

What side effects can Cialis have?

Cialis (tadalafil) is generally well-tolerated, but like all medications, it can cause side effects.

Common side effects (1%-10% of users):

These mild side effects usually go away shortly after taking the medication:

  • Headaches
  • Indigestion
  • Stuffy nose
  • Muscle pain
  • Back pain

If these symptoms persist or bother you, consult your doctor.

Serious side effects (less common):

Serious side effects are rare but can include:

  • Chest pain
  • Faster heart rate
  • Hearing loss or ringing in the ears
  • High or low blood pressure
  • Prolonged erections (priapism)
  • Severe allergic reactions

Priapism

This is a rare but serious condition involving a prolonged, painful erection lasting several hours. It requires immediate medical attention to prevent permanent damage.

How to minimise side effects

  • Use the lowest effective dose of Cialis as recommended by your doctor.
  • Always check the patient leaflet included with the medication for a complete list of side effects.
  • If you experience severe or persistent side effects, consult your doctor immediately.

For more guidance, speak to your healthcare provider to ensure Cialis is safe and effective for you.

How long do Cialis side effects last for?

Cialis side effects usually go away after a few hours (Eli Lilly and Company, 2024), but back pain and muscle aches may take up to 2 days to improve. If you experience any side effects while taking Cialis tablets, speak to your doctor as soon as possible.

For further information on the side effects of Cialis, please refer to the patient information leaflet that is supplied with the medication and consult with your doctor at the first sign of any side effects.

How can you avoid Cialis (tadalafil) side effects?

You can reduce the chances of experiencing side effects from Cialis by following these simple tips:

  • Stay hydrated: Drink plenty of water throughout the day.
  • Avoid spicy or rich foods: These may worsen side effects like indigestion.
  • Keep cool: Use a fan or stay in a cool environment if you feel flushed.
  • Take antacids: If advised by your doctor, antacids can help manage indigestion.

Can grapefruit increase the risk of side effects with Cialis?

Yes, eating grapefruit or drinking grapefruit juice can increase the risk of side effects when taking Cialis, including Cialis Daily or Cialis Together.

Why Avoid Grapefruit?

Grapefruit can affect how your body processes the medication, leading to higher levels of Cialis in your blood. This increases the chance of side effects such as headaches, flushing, or dizziness.

Key Tip

Avoid grapefruit and grapefruit juice while taking Cialis and for a few days after stopping the medication. For more guidance, consult your doctor or pharmacist.

Warnings

What warnings and precautions does Cialis come with?

Cialis (tadalafil) is generally safe when used as directed, but it comes with some important precautions:

Do not take Cialis if:

  • You use poppers (amyl nitrate) or have been prescribed nitrate-based medicines like isosorbide mononitrate or GTN spray.
    • Combining these with Cialis can cause a dangerous drop in blood pressure that may be life-threatening.

Dependence and addiction

  • No physical addiction: Cialis is not addictive, and you won’t experience withdrawal symptoms if you stop taking it.
  • No psychological dependence when used correctly: However, improper use (e.g., taking it to enhance sexual performance unnecessarily) could lead to psychological dependence or unwanted side effects.

Stay safe

Always take Cialis as prescribed by your doctor and avoid misuse. If you have concerns about interactions or side effects, consult your doctor or pharmacist for advice.

Cialis FAQs

UK Meds answer some of the most common questions that ED patients ask us about Cialis below:

Can alcohol interact with Cialis?

Yes, drinking alcohol while taking Cialis (tadalafil) can cause interactions that may lower your blood pressure, leading to side effects such as:

  • Fainting
  • Dizziness
  • Headaches

Why avoid alcohol with Cialis?

Both alcohol and Cialis can reduce blood pressure, and combining them increases the risk of orthostatic hypotension (a sudden drop in blood pressure when standing).

Recommendation

Your doctor may advise you to limit alcohol consumption while using Cialis to reduce the risk of side effects. Always follow their guidance for safe use. If you have questions, consult your doctor or pharmacist.

Can I become psychologically dependent on Cialis?

No, there is no evidence to suggest that using Cialis (tadalafil) correctly at the recommended dose leads to dependence or tolerance.

Is Cialis physically addictive?

No, Cialis (tadalafil) is not physically addictive.

  • Unlike certain medications, such as opioids, Cialis does not cause physical addiction or withdrawal symptoms if you stop taking it.
  • There is no evidence that erectile dysfunction (ED) medicines like Cialis lead to physical dependence.

What precautions does Cialis come with?

Before starting treatment with Cialis (tadalafil), your doctor will advise you on any precautions you need to consider.

Important interactions to avoid:

According to the NHS (2022), certain medications and substances can interact negatively with Cialis, including:

  • Riociguat (used for pulmonary hypertension).
  • Nitrates (used for chest pain, such as GTN spray or isosorbide mononitrate).
  • Recreational poppers (amyl nitrate).
  • Some herbal remedies and supplements.

These interactions can lead to dangerous side effects, such as severe drops in blood pressure.

Is Cialis stronger than Viagra?

Cialis and Viagra are both effective treatments for erectile dysfunction (ED), but their active ingredients and duration of action differ:

  • Cialis contains tadalafil, while Viagra contains sildenafil.
  • Cialis is not "stronger" than Viagra in helping to achieve erections, but it does have a longer duration of action. Cialis can work for up to 36 hours, compared to Viagra, which typically lasts 4-6 hours.

If you’re unsure which medication is right for you, consult your doctor or pharmacist for advice tailored to your needs.

How does Cialis (tadalafil) work for different health conditions?

Cialis (tadalafil) is a PDE5 inhibitor that helps improve blood flow in the body, offering treatment for several conditions.

For Erectile Dysfunction (ED)

  • Tadalafil temporarily increases blood flow to the penis, helping men achieve and maintain a firmer, longer-lasting erection when sexually aroused.

For Enlarged Prostate (Benign Prostatic Hyperplasia)

  • Tadalafil relaxes muscles in the prostate and bladder, helping reduce symptoms like:
    • Urgent need to urinate.
    • Difficulty starting or maintaining urination.

For Pulmonary Hypertension

  • Tadalafil relaxes blood vessels in the lungs, lowering the heart's workload and improving blood flow to the lungs. This makes it an effective treatment for pulmonary hypertension.

Important advice

Always consult your doctor to determine if Cialis (tadalafil) is suitable for your specific needs and medical condition. Your healthcare provider will recommend the safest and most effective treatment.

Can Cialis treat premature ejaculation?

No, scientific studies have shown that while a 5mg daily dose of tadalafil (the active ingredient in Cialis) is safe, it does not provide a statistically significant improvement for treating premature ejaculation (Faddan et al., 2022).

What does this mean?

  • Cialis is effective for managing erectile dysfunction (ED) but is not proven to be a reliable treatment for premature ejaculation.
  • If you are experiencing premature ejaculation, consult your doctor for alternative treatments and personalised advice.

Alternative ED Treatments

ED Counselling Therapy

If your doctor thinks psychological issues are the root cause of your erectile dysfunction they may recommend a non-drug alternative treatment such as ED counselling therapy, which can help you to understand if mental issues such as a lack of sexual desire (low libido), stress or anxiety are causing you to experience erectile dysfunction (NHS, 2023).

1. ED Counselling Therapy

If psychological factors such as low libido, stress, or anxiety are causing your ED, your doctor may suggest counselling or therapy.

  • Therapy helps address mental health issues that could be affecting your sexual performance.
  • Counselling services for ED may be available through the NHS (NHS, 2023).

2. Lifestyle Changes

For ED caused by physical health issues, such as high cholesterol or cardiovascular disease, your doctor may recommend:

  • Eating a balanced diet.
  • Regular exercise.
  • These lifestyle improvements can enhance overall health and positively impact erectile function (Yannas et al., 2021).

3. Alternative ED Medications

In addition to oral PDE5 inhibitors like Viagra, there are other effective ED treatments:

Which option is best for you?

Your doctor or healthcare provider will assess your individual needs and recommend the most suitable treatment. Whether addressing psychological or physical factors, a tailored approach can significantly improve your symptoms.
