CHATHAM - Officials say a CVS Pharmacy in Chatham somehow mixed up prescription fluoride pills for children with a breast cancer medication.

Now everyone from the pediatricians to large medical groups, to the drug store, are getting in touch with patients to see if their children mistakenly got the drug Tamoxifen.

Experts say fluoride pills and Tamoxifen look very similar, which may have contributed to the mix-up.

The Tamoxifen may have mistakenly given to patients between Dec. 20 and Feb. 20th. Officials are advising parents to check their pills and contact the pharmacy or their doctors if they have any doubts.
