Ask a Question


A response to a submitted query relates only to known or suspected effects on drug exposure of interacting medications, and is based on relevant data in the public domain, and completeness of information supplied by the requester. No clinical advice is given or implied, clinicians must exercise their own judgement in relation to the risks and benefits of combining drugs, which depend on factors beyond pharmacokinetic interactions between two drugs. The University of Liverpool shall not be held responsible for the application or use of any response it gives and the requester shall hold the University of Liverpool harmless against any consequences arising from the same.
