What medications can cause increased liver enzyme tests (AST and ALT) levels?
A variety of medications can cause abnormal liver enzymes levels in some individuals.
Examples of some of the common medications with potential liver toxicity include:
Pain relief medications such as:
- acetaminophen (Tylenol and others),
- ibuprofen (Advil, Motrin),

Anti-seizure medications such as:
- phenytoin (Dilantin),
- valproic acid (Depakote, Depakote ER, Depakene, Depacon),
- carbamazepine (Tegretol, Tegretol XR, Equertro), and
Antibiotics such as:
- tetracyclines, (for example, tetracycline [Achromycin])
- isoniazid (INH) (Nydrazid, Laniazid)
- sulfamethoxazole (Gantanol),
- trimethoprim (Trimpex; Proloprim, Primsol)
- nitrofurantoin (Macrodantin; Furadantin; Macrobid),
