I would call and ask prior to taking any medication. In Alberta they have a triage telephone line that is available 7 days a week to answer those types of questions. Not sure what other areas have available.
Even in Toronto we have 24/7 number to call to answer those questions , we can not take meds because it might have conflict with our chemo meds. So please try to reach your triage nurse before taking any pills for your own safety.
