It is very important that trial participants do not take other medications that contain ASA whilst they are taking part in the study. It is also important that participants do not take ASA bought over the counter from a pharmacy or shop. This may be unsafe and significantly increases the risk of side effects, like ulcer. Your study doctor or GP will be able to advise you on this.

The following medications should not be taken at the same time as long as you are on study medication. If you are unsure whether you can take a medication please discuss with your study doctor or GP.
