Recommendations for Chronic Medications the Day of Anesthesia

Continue medications as scheduled:

  • Thyroid medication: thyroid supplement or Methimazole

  • Behavioral and pain medications: sudden withdrawal of these medications is not advised in most cases. If NSAID is being used (Like Carprofen or Meloxicam), we usually give these injections the day of the procedure due to the patient fasting.

  • Oral anxiolytics: to reduce fear and anxiety (Trazodone, Acepromazine, Gabapentin, etc)

  • Cardiac medications: Pimobendan, Furosemide

  • Anti-seizure medications: Phenobarbital, Potassium Bromide, Levetiracetam, Zonisamide

  • Antibiotics

  • Steroids: should never be abruptly stopped

Discontinue the day of anesthesia

  • Antihypertensive medication, especially ACE inhibitors: enalapril, benazepril

  • Anticoagulants: may need to be discontinued 2 wk prior to anesthesia based on the risk of bleeding

Administer based on specific recommendations to owner:

  • Insulin: A full dose should not be administered to fasted patients because of the risk of hypoglycemia. It is advised to give a half dose and has the owner bring their insulin with them when they drop off. We will check blood glucose throughout the day and give additional if needed, or supplement sugars if blood glucose falls low throughout the day.

* List is not all-inclusive but focuses on medications strongly recommended to either administer or cease.
