  2. Key facts

    • Ibuprofen takes 20 to 30 minutes to work if you take it by mouth. It takes 1 to 2 days to work if you put it on your skin.
    • Ibuprofen works by reducing hormones that cause pain and swelling in the body.
    • Ibuprofen is typically used for period pain or toothache. Some people find ibuprofen better than paracetamol for back pain.
    • Always take ibuprofen tablets and capsules with food or a drink of milk to reduce the chance of an upset tummy. Don't take it on an empty stomach.
    • If you're taking tablets, take the lowest dose for the shortest time. Don't use it for a long time unless you've talked about it with your doctor. Don't use the gel, mousse or spray for more than 2 weeks without talking to your doctor. 
    • Ibuprofen is called by different brand names, including Nurofen, Brufen and Calprofen (syrup). Ibuprofen gel can be called Fenbid, Ibugel and Ibuleve.
  3. Who can and can't take ibuprofen

    Some brands of ibuprofen tablets, capsules and syrup contain aspartame, colours (E numbers), gelatin, glucose, lactose, sodium, sorbitol, soya or sucrose, so they may be unsuitable for some people.

    • have had an allergic reaction to ibuprofen or any other medicines in the past
    • have previously had a reaction, such as asthma, a raised, itchy red rash (urticaria), swelling underneath your skin (angioedema) or swelling of the inside of your nose (rhinitis) 
    • have taken aspirin or any other NSAID
    • have asthma or another allergic illness

  4. How to take tablets, capsules and syrup

    The usual dose for adults is one or two 200mg tablets 3 times a day. If this isn't enough, your doctor may prescribe a higher dose of up to 600mg to take 4 times a day. 

    If you take ibuprofen 3 times a day, leave at least 6 hours between doses. If you take it 4 times a day, leave at least 4 hours between doses.

    If you have pain all the time, your doctor may recommend slow-release ibuprofen tablets or capsules. It's usual to take these once a day in the evening or twice a day. Leave a gap of 10 to 12 hours between doses if you're taking ibuprofen twice a day.

    For people who find it difficult to swallow tablets or capsules, ibuprofen is available as a tablet that melts in your mouth, granules that you mix with a glass of water to make a drink, and as a syrup.

    Swallow ibuprofen tablets or capsules whole with a glass of water or juice. Don't chew, break, crush or suck them as this could irritate your mouth or throat.

    Always take ibuprofen tablets and capsules after a meal or snack or with a drink of milk. It will be less likely to upset your tummy.

    What if I forget to take it?

    Take the missed dose as soon as you remember, unless it's almost time for your next dose. In this case, skip the missed dose and take your next dose as normal.

    Never take a double dose to make up for a forgotten one.

    If you forget doses often, it may help to set an alarm to remind you. You could also ask your pharmacist for advice on other ways to help you remember to take your medicine.

    What if I take too much?

    Taking too much ibuprofen by mouth can be dangerous. It can cause side effects such as:

    • feeling sick and vomiting
    • tummy pain
    • feeling tired or sleepy
    • black poo and blood in your vomit - a sign of bleeding in your stomach
    • tinnitus (ringing in your ears)
    • difficulty breathing or changes in your heart rate (slower or faster)

    If you've taken more than the maximum dose of ibuprofen, call your doctor or go to your nearest hospital accident and emergency (A&E) department as soon as possible.

    If you need to go to hospital, take the ibuprofen packet or leaflet inside it plus any remaining medicine with you.

  5. How to use ibuprofen gel, mousse or spray

    The amount of ibuprofen you put on your skin depends on the product you're using - check the package leaflet carefully for how much to use.

    Gently massage the ibuprofen into the painful area 3 or 4 times a day. Leave at least 4 hours between applications, and don't put it on more than 4 times in 24 hours.

    Never use ibuprofen gel, mousse or spray on your eyes, mouth, lips, nose or genital area. Do not put it on sore or broken skin. Do not put plasters or dressings over skin you've applied ibuprofen to.

    What if I forget to put it on?

    Don't worry if you occasionally forget to use it, just carry on using it when you remember.

    What if I put on too much?

    Putting too much ibuprofen on your skin is unlikely to cause problems.

    What if I accidentally swallow the gel?

    If you swallow ibuprofen gel or mousse by accident, you may get symptoms including:

    • headache
    • vomiting
    • feeling sleepy

    If you get a headache, vomit or feel sleepy after accidentally swallowing ibuprofen gel, contact a doctor or hospital straight away.

  6. Taking ibuprofen with other painkillers

    It's safe to take ibuprofen with paracetamol or codeine.

    But don't take ibuprofen with similar painkillers like aspirin or naproxen without talking to a doctor.

    Ibuprofen, aspirin and naproxen belong to the same group of medicines called non-steroidal anti-inflammatory drugs (NSAIDs). If you take them together, ibuprofen plus aspirin or naproxen may increase the chance of you getting side effects like stomach ache.

  8. Side effects of gel, mousse and spray

    Applying ibuprofen to your skin can also cause your skin to become more sensitive than normal to sunlight.

    These are not all the side effects of ibuprofen gel, mousse and spray. For a full list see the leaflet inside your medicines packet.

  9. How to cope with side effects

    What to do about:

    • indigestion - stop taking ibuprofen and see your doctor as soon as possible. If you need something to ease the discomfort, try taking an antacid, but don't put off going to the doctor.
    • feeling sick - stick to simple meals. Don't eat rich or spicy food
    • vomiting - have small, frequent sips of water. It may also help to take oral rehydration solutions you can buy from a pharmacy or supermarket to prevent dehydration. Don't take any other medicines to treat vomiting without speaking to a pharmacist or doctor.
    • wind - try not to eat foods that cause wind (like pulses, lentils, beans and onions). Eat smaller meals, eat and drink slowly, and exercise regularly. There are pharmacy medicines that can also help, such as charcoal tablets or simethicone.
    • your skin being sensitive to sunlight - stay out of bright sun and use a high factor sun cream (SPF 15 or above) even on cloudy days. Don't use a sun lamp or sun beds.
