Reporting Suspected Side Effects

Most of us will not experience any problems when using medicines. However, all medicines have some risks associated with their use and so a small number of people may experience side effects (also known as adverse reactions).

If you are concerned that you have had a suspected adverse reaction to a medicine, you may need to contact your healthcare professional who can advise on any treatment that may be needed. They can also report the issue to the HPRA on your behalf.

If you wish to directly report an adverse reaction, you can use our online reporting service. Anyone can report issues relating to the safety of medicines to the HPRA. This includes patients, carers, other members of the public and healthcare professionals.

Access to information from adverse reaction (i.e. side effect) reports

Adverse reaction reports received by the HPRA are processed and entered into the national database. These reports (with personal details excluded) are subsequently sent to EudraVigilance, the European Medicines Agency’s (EMA’s) database of suspected adverse reactions, where the data are analysed to detect new safety signals. Anonymised data from individual adverse reaction reports submitted to the EMA are publically accessible for review at
