The most common drugs responsible for acneform eruptions are ACTH, androgenic hormones, anticonvulsants (hydantoin derivatives, phenobarbital, trimethadione), corticosteroids, danazol, disulfiram, halogens (bromides, chlorides, iodides), lithium, oral contraceptives, tuberculostatics (ethionamide, isoniazid, rifampin), vitamins B2, B6, and B12. 

Phenytoin serum levels are markedly and rapidly increased by disulfiram. Phenytoin toxicity can develop. There is evidence that phenobarbital and carbamazepine are not affected by disulfiram, and that phenytoin is not affected by calcium carbimide. 

Carbamazepine and phenobarbital do not appear to interact with disulfiram and calcium carbimide does not appear to interact with phenytoin.
