I found a pill that's says 2003 on one side and teva on the other, it's peach and round what is it?

The imprint is incorrect, it is Teva 2083.-The description of the pill is right.

Pill imprint TEVA 2083 has been identified as Hydrochlorothiazide 25 mg.

Hydrochlorothiazide is used in the treatment of high blood pressure; edema; osteoporosis; diabetes insipidus; nephrocalcinosis and belongs to the drug class thiazide diuretics. There is no proven risk in humans during pregnancy.

Hydrochlorothiazide 25 mg is not subject to the Controlled Substances Act.
