Forgotten when you took your last paracetamol? Or maybe you accidentally mixed your meds. Here’s why it’s important to read the instructions and always stick to the recommended dosage.
Here are 8 common mistakes people make when it comes to taking painkillers.
#1 You’re taking too many
Reaching for the painkillers to quash that pounding headache? People often think that doubling the dose of painkillers will double their effectiveness, so they take more in the hope it will target the pain much quicker. This isn’t true! Always read the instructions properly and take the recommended specified amount:
Paracetamol dosage for adults is usually one or two 500mg tablets up to 4 times a day.
Ibuprofen is one or two 200mg tablets every four to six hours. You can take ibuprofen and paracetamol together, but be mindful of other medications that you are taking. Double check that they don't contain the same active ingredients. For example, many cold and flu remedies contain paracetamol or ibuprofen together with a decongestant. Taking too much paracetamol can lead to a build-up of the drug in the body, and you run the risk of nausea or an upset stomach, heartburn, rashes, or even liver or kidney damage.
#2 You don’t read the instructions properly
You can take paracetamol on an empty stomach, but non-steroidal anti-inflammatory medicines, such as ibuprofen and aspirin, should be taken with or after food. This helps to reduce irritation of the stomach lining, which can cause indigestion, heartburn pain and nausea.
Other painkillers like aspirin can also eat away at the lining of your gut. Pain relief such as codeine, endone and morphine should only be used short term to treat acute pain. Taking them for longer than the recommend dosage can lead to addiction and withdrawal symptoms when you stop taking it.
Our advice is to read the instructions properly and always stick to the recommenced amount.
#3 You forget when you took the last one
Although this might sound silly, so many people forget when they took their last dose and miscalculate when another dose is due. This means the body cannot metabolise the medicine effectively. Although paracetamol and ibuprofen can be taken together, it’s a good idea to make a note of what time you took your last dose, so that you can spread it out evenly and reduce the risk of taking too many.
#4 You use someone else’s prescription
Doctors prescribe painkillers for patients based on their individual needs. They will take into account any allergies you may have, and your past medical history. If you take someone else’s prescribed medication, it can be dangerous — you may be allergic to the ingredients, it could interact with another medicine you are taking, or it may not be suitable for you. If you are unsure, talk to your health care professional for further advice.
#5 You drive after taking codeine
Codeine is a mild opiate in the same class of drugs as morphine. It can make you drowsy and slow your reaction times, making you more likely to make mistakes. If you find that you feel sleepy or dizzy after taking a painkiller containing codeine, you should not drive or operate heavy machinery of dangerous equipment.
#6 You assume all OTC meds are the same
Different strains of painkillers contain different active ingredients, and they each target different pain points. You should take each painkiller’s specific method of action into account when choosing a pain reliever, rather than just popping whatever you have in your medicine cabinet.
For example, ibuprofen works by reducing hormones that cause pain and swelling in the body. This makes it a great option for arthritis pain and swelling, but it might not be as effective at treating a headache. In that case, paracetamol might be your best bet, since it works by blocking chemical messengers in the brain that tell us we have pain.
Different painkillers also have different side effects. Depending on your personal health history — if you have high blood pressure or you’re a heavy drinker, for example — you may want to avoid certain medication.
Heavy drinkers and/or people with existing liver conditions should be mindful of the amount of paracetamol they’re taking, as it could cause a problem for the liver in the long run. Anyone suffering with high blood pressure should also avoid ibuprofen, as it increases the risk of heart disease or stroke.
If you’re unsure, talk to your pharmacist who will advise you which course of mediation to take.
#7 You mix your meds
Before taking any painkiller, think about what other medication, herbal remedies and supplements you’re taking. Some of these drugs and supplements could interact with pain medications or increase the risk of their side effects.
For example, if you take endone or morphine together with anti-depressants, this can cause drowsiness and respiratory depression (hypoventilation). Some drugs also enhance the effectiveness of other drugs, which could be fatal.
Give your doctor a complete list of all the drugs, herbs, and supplements you take before you get your prescription. For any over-the-counter medications, show a list of everything you're currently taking to the pharmacist so you can be sure you won’t have a reaction.
#8 You mix alcohol with codeine
Codeine and alcohol are both depressant drugs, which means they can cause sleepiness and drowsiness when taken together. Other effects include feelings of lightheadedness, trouble concentrating, fainting, impaired thinking and judgment, delayed motor skills and reaction time, respiratory distress, and low blood pressure. These can also cause other fatal repercussions, such as falls, car accidents, and other injuries like broken bones, so it’s advised not to drink at all if prescribed this medication.
