Phenobarbital and phenytoin may increase vitamin D requirements.

Phenytoin and phenobarbital may alter each other's metabolism. Both reduce levels of abacavir, amprenavir, TCAs, aprepitant, apripiprazole, carbamazepine (phenytoin levels reduced), valproate, clonazepam, lamotrigine, tacrolimus (phenytoin levels may increase) and theophylline. Phenytoin and phenobarbital may decrease effects of systemic corticosteroids, ciclosporin, coumarins, digitoxin, oestrogens and progestogens. Valporate may increase levels of phenobarbitone and phenytoin (levels may conversely increase). Antipsychotics, TCAs, SSRIs and TCA related antidepressants may antagonise effects of phenytoin and phenobarbital. Phenytoin reduces levels and effects of bupropion, busulfan, caspofungin, digoxin, disopyramide, eplerenone, imatinib, levodopa, mirtazapine and furosemide. Levels of phenytoin may be reduced by antacids (separate doses by a couple of hr), sucralfate, carbamazepine and theophylline. Phenytoin levels may be affected by benzodiazepines and ciprofloxacin. Levels of phenytoin may be increased by cimetidine, clarithromycin, diazepam, fluoxetine, fluconazole, fluvoxamine, itraconazole, ketoconazole, metronidazole, sulphonamide, topiramate (may reduce topiramate levels), trimethoprim (antifolate effect) and amiodarone (interaction may continue for wk or mth. Phenytoin effects may be enhanced by influenza vaccine, esomeprazole and NSAIDs. Increased risk of withdrawal symptoms when phenytoin is used with methadone. Pyrimethamine may antagonise phenytoin effects. Phenytoin may increase antifolate effect of methotrexate. Concomitant use of phenobarbital and carbonic anhydrase inhibitors may increase risk of osteomalacia. Chlorpromazine and phenobarbital levels may be reduced when given together. Phenobarbital reduces effects of dihydropyridine calcium channel blockers, diltiazem, felodipine, nelfinavir, verapamil, griseofulvin, doxycycline, disopyramide, thyroid hormones, tibolone, haloperidol and mianserin. Phenobarbital reduces levels of chloramphenicol, indinavir, rifampicin, telithromycin (avoid 2 wk before or after phenobarbital), ethosuximide, itraconazole and voriconazole (avoid concomitant use). Folates may decrease phenobarbital levels. Methylphenidate may increase phenobarbital levels. Potentially Fatal: Lithium toxicity may occur when used with phenytoin (even without increased lithium levels). Concomitant use of phenytoin with chloramphenicol or voriconazole may lead to increased, possibly, toxic levels of phenytoin (and reduced voriconazole levels).

Side effects of Phenobarbitone (Phenobarbital) + Phenytoin : Sedation, depression, irritation, aggressiveness, confusion, paradoxical excitation in children, rash, dyskinesia, macrocytic anaemia, thyroiditis, vertigo, nystagmus, ataxia, diplopia and gingival hypertrophy. Potentially Fatal: Agranulocytosis, aplastic anaemia, exfoliative dermatitis (Stevens Johnson syndrome), severe hepatitis and leucopenia.

Phenytoin and phenobarbital both depress the motor cortex, raise the seizure threshold and reduce spread of seizure. Phenytoin stabilises neuronal membrane, inhibiting movement of sodium and calcium ions during the nerve impulse. Phenobarbital aids gamma-aminobutyric acid (GABA)-mediated inhibition of nerve cells.
