Questions for your clinician or pharmacist
- Is my total zinc above my allowance, and is there a reason for that?
- Given how long I have taken this amount, should my copper be checked?
- Do any of my medicines, such as acid reducers, penicillamine or trientine, change my zinc or copper needs?
- Does my multivitamin already contain the copper I need?
