Consumer:

Consumer information for this minor interaction is not currently available. Some minor drug interactions may not be clinically relevant in all patients. Minor drug interactions do not usually cause harm or require a change in therapy. However, your healthcare provider can determine if adjustments to your medications are needed.

Professional:

In vitro data indicate that carbonic anhydrase inhibitors (CAIs) may significantly inhibit the binding or uptake of chlorthalidone in erythrocytes. Theoretically, this interaction could significantly increase the free, unbound fraction of chlorthalidone. The clinical consequences are not known, and more study is needed. The clinician should be aware that increased serum chlorthalidone levels and increased pharmacologic effect are possible during coadministration.
