When checking interaction based on authoritative sources Drugs.com, Rxlist.com, Webmd.com, Medscape.com there are contraindications or side effects that may cause harm or increase the negative effect from drug use in presence of concomitant diseases.

Consumer:

The use of phenytoin has rarely been associated with exacerbation of porphyria. Therapy with phenytoin should be administered cautiously in patients with porphyria. The same precaution should also be observed with other hydantoin anticonvulsants (i.e. ethotoin and mephenytoin) because of their structural and pharmacological similarities to phenytoin.
