Infant Tylenol Drug Interactions
If phenobarbital, isoniazid, or non-prescription cold and cough medications are combined with infant Tylenol, drug interactions may potentially occur. Some drugs may affect the way the body handles Tylenol, while others can increase the risk of liver damage. To help prevent infant Tylenol interactions, make sure to tell your child's healthcare provider about all other medicines your child is taking.
Infants' Tylenol® (infant acetaminophen) can potentially interact with other medications. However, many of these medications are not usually used by young children. Some of the children's medicines that may lead to infant Tylenol drug interactions include:
- Carbamazepine (Carbatrol®, Epitol™, Equetro®, Tegretol®)
- Codeine and acetaminophen (Capital® and Codeine, Phenco-Care™, Tylagesic™, Tylenol No. 3, Tylenol No. 4)
- Isoniazid (Nydrazid®)
- Many non-prescription cough, cold, flu, and allergy products
- Phenobarbital (Luminal®)
- Warfarin (Coumadin®, Jantoven®).
The following sections explain in detail the potentially negative interactions that can occur when infant Tylenol is combined with any of the drugs listed above.
Carbamazepine (Carbatrol, Epitol, Equetro, Tegretol)
Carbamazepine can affect the way the body handles infant Tylenol, making both drugs less effective and more toxic. Talk to your child's healthcare provider about using infant Tylenol in children who take carbamazepine.
Codeine and Acetaminophen (Capital and Codeine, Phenco-Care, Tylagesic, Tylenol No. 3, Tylenol No. 4)
In general, you should avoid giving your child infant Tylenol if he or she is taking codeine and acetaminophen products, as you may give your child too much acetaminophen (the active ingredient of infant Tylenol).
