Frequently asked questions

Can tadalafil cause high blood pressure?

In some cases, tadalafil can cause high blood pressure, but this is uncommon. You shouldn’t take tadalafil if you have low blood pressure or uncontrolled high blood pressure. Speak with your doctor if you have any questions about this before taking tadalafil.

Are tadalafil tablets safe?

Yes, tadalafil tablets are safe and effective for men who have erectile dysfunction. You should only take tadalafil tablets if they have been prescribed to you, and you should never take more than your prescribed dose. Your doctor will make sure tadalafil is a safe and suitable treatment for you before prescribing it.

Can tadalafil and sildenafil be taken together?

No, you should not take more than one erectile dysfunction medication at a time. This could increase the risk of serious side effects and could be dangerous, especially if you have other medical conditions or take certain medications.

If you think your ED treatment is not working and you want to try another medication or change your dose, speak to your doctor.

Why does tadalafil cause headaches?

Tadalafil relaxes the blood vessels in your body, which can also affect the blood vessels in your brain. This is why tadalafil and other PDE5 inhibitors commonly cause headaches.

If you get headaches whilst taking tadalafil, they often go away or become milder once your body gets used to the treatment. You can use over the counter painkillers like paracetamol to treat headaches. You can also try drinking plenty of water and resting in a dark, quiet room until your symptoms improve.

Speak to your doctor if you keep getting headaches when taking tadalafil or if they become unbearable.

Can tadalafil cause heartburn?

Tadalafil can cause heartburn, but it does tend to go away on its own within a few hours of taking the medication. If you do get heartburn with tadalafil, try taking the tablet with a large glass of water or eating a small meal beforehand. Avoid taking antacids with tadalafil, as these can affect how it is absorbed, making it less likely to work effectively.

Why isn’t tadalafil working for me?

If tadalafil is not working, it might be because you:

  • haven’t waited long enough between taking the tablet and having sex
  • are not on the correct dose
  • are not sexually aroused
  • have waited too long after taking the tablet to have sex
  • have consumed alcohol, as this can affect your ability to get and maintain an erection

If tadalafil isn’t working for you, it may be because you need to give it more time. You should take tadalafil on 8 different occasions before trying another ED treatment or increasing the dose with your doctor.

Does tadalafil make you harder?

Tadalafil can make it easier for you to get and maintain an erection, but it cannot make your erection harder than it normally would be.

Can tadalafil be split in half?

No, you should always take your tablet whole. Splitting it in half can make it less effective. If you think your dose is too high, you should speak to your doctor before attempting to adjust it yourself.

Can tadalafil be taken with alcohol?

You can drink alcohol whilst taking tadalafil, but it can affect how well it works and make side effects more likely. Drinking alcohol makes it harder to get an erection whether you’re taking ED treatment or not, so drinking alcohol with tadalafil will make it harder to get an erection.

You should not drink alcohol excessively when taking tadalafil as this can increase the risk of certain side effects, such as low blood pressure and dizziness when standing up.

Can tadalafil be taken daily?

Tadalafil is not recommended for daily use when prescribed in 10mg or 20mg tablets. If you are taking tadalafil almost every day, speak to your doctor. There are alternative daily ED treatments that may be more suitable, such as Cialis Daily, which contains 5 mg of tadalafil.

How long does tadalafil stay in your system?

Tadalafil can stay in your system for up to 36 hours.

How often can you take tadalafil?

You should not take more than 1 tadalafil dose in 24 hours. If you think tadalafil is not working for you or you are taking it often, speak to your doctor.

Is tadalafil stronger than sildenafil?

Tadalafil is not stronger than sildenafil, tadalafil just lasts longer. Both medications are just as effective in treating ED. What’s important is finding which treatment works best for you and matches your needs. ED treatments vary in how they work from person to person, so you may need to try a few to find the one that gives you the best results.

Will tadalafil make you last longer in bed?

Tadalafil can help you to get and maintain an erection easier, but it cannot make you last longer in bed or treat premature ejaculation. If you are having problems with premature ejaculation, there are treatments that can help.
