Are there any medical contraindications with Can-C?
As with the use of all medicinal preparations you should consult your physician or medical professional when commencing or adding any new product to an existing regimen. To date there have been no medications that interfere with the effectiveness of Can-C or vice versa. To be cautious it is perhaps advisable to not take any preparations within 1 hour, before or after applying Can-C. Perhaps be especially careful if you are using another eye drop.
