What is a side-effect?
We use medicines to help our children, but sometimes they have effects that we don’t want, such as feeling sick or getting a rash. These are called side-effects.
How do I know if my child has side effects?
If your child develops any new symptoms after starting a medicine, or at any other time, these may be side-effects. However, often it is difficult to be certain whether a medicine has definitely caused the symptoms or whether they are due to your child’s health condition or a new illness. If your child is taking lots of different medicines, it can also be difficult to work out which (if any) medicine or medicines have caused the symptoms.
What should I do if I think my child has a side-effect?
If it is a mild effect that is not causing your child any problem, you may not need to do anything immediately. However, if you are worried or it gets worse contact your doctor, pharmacist or nurse. If your child is very unwell take them to hospital. If you think your child is getting side-effects, it may helpful to keep a diary of when your child takes their medicines and any symptoms you notice – this will be useful to your doctor, pharmacist or nurse when working out what is causing the problem.
How long do side-effects last?
Children may get side-effects such as headache or nausea (feeling sick) when they first start taking a new medicine but these often wear off after a few days. Some side-effects will continue while your child is taking the medicine. Your doctor will give you advice about how to manage these side-effects.
What can my doctor do if side-effects are a problem?
Your doctor may be able to reduce the dose of the medicine so that your child can get used to it, or swap to a different medicine. You should not reduce the dose or stop giving the medicine without talking to your doctor. Sometimes you may need to discuss the balance between the benefits of treatment and the side-effects and whether these are acceptable. Your doctor will note in your child’s records if a particular medicine causes problems. It may be useful to keep a note of the name of the medicine, in case another doctor prescribes it. This is particularly important if your child has ever had an allergic reaction to a medicine.
Where can I find more information about side-effects?
Most medicines come with an information leaflet that explains what the medicine is for and how to take it. The leaflet also lists the possible side-effects ranging from those that are fairly common to those that are very rare. Information about side-effects is also given on the individual medicines pages for each antibiotic by searching here: Medicines Information
Reporting side-effects to the medicines safety ‘watchdog’
The Medicines and Health Care products Regulatory Agency (MHRA) is the watchdog for the safety of medicines in the UK. The MHRA monitors side-effects through its YellowCard scheme. This acts as an early warning system to identify new side-effects and get more information about other problems that might not have been known about before. If a new side-effect is identified, the MHRA will review the way the medicine is used, and any warnings that are needed to help minimise risk whilst maximising the benefit to the patient.
Anyone can report a side-effect to the MHRA via its Yellow Card Scheme:
- Website – www.yellowcard.mhra.gov.uk
- Freephone – 0808 100 3352 (10am to 2pm Monday-Friday only)
- Via the MHRA’s downloadable app
