The Illinois Council of Health-System Pharmacists (ICHP) supports the practice of therapeutic interchange.

Therapeutic interchange occurs when a therapeutically equivalent drug product is dispensed in place of the specific drug product prescribed.  Therapeutic equivalents are drug products that differ in chemical composition or are different drug entities considered to have similar pharmacologic and /or therapeutic actions.  Therapeutic equivalence amongst products is mutually agreed upon by pharmacists and prescribers, frequently through the Pharmacy and Therapeutics Committee (or equivalent) and effectively communicated to stakeholders.
