What To Tell Your Doctor or Pharmacist
If you are taking Valproic Acid and your doctor is considering prescribing Ertapenem (or vice versa), make sure to:

- Ask whether the benefits of combining these medications outweigh the risks for your specific situation
- Ask what symptoms to watch for that would indicate the interaction is causing problems
- Ask how frequently you should be monitored while these are co-prescribed
- Ask whether any dosage adjustments are needed
- Never stop or change either medication without first consulting your healthcare provider
