Will Paludrine Avlocolor Malaria Tablets Cause Side Effects In Ibs Sufferers?

My family and I are going abroad in a few weeks. We need to get malaria tablets but we found out that that the pills can cause vomiting and diarrhoea in some people and this may be even worse for people with a gut problem and so such people should avoid taking them. My mum suffers from IBS. Does this mean it isn’t safe for her take the tablets or can she take them regularly at a normal dose?
