Drug-induced gingival overgrowth (DIGO) is an adverse drug reaction mainly described with three types of commonly prescribed drugs, namely, calcium channel blockers (CCBs) (nifedipine, diltiazem, and verapamil), anti-convulsants (phenytoin), and immunosuppressive agents (cyclosporine). Numerous reports have associated gingival overgrowth with the newer generation of immunosuppressive agents (tacrolimus, sirolimus, and everolimus), and CCBs (amlodipine, felodipine, nicardipine, and manidipine). Especially, patients concomitantly medicated with an immunosuppressive agent and CCB have a higher DIGO chance. Dentists need to be aware of drugs that induce gingival overgrowth, the possibility of DIGO, and risk factors, and also prevent the progression of DIGO by early detection of DIGO, consultation about the drug change, and the maintenance of strict dental hygiene regimes.
