The following medications should be used with caution when given with dextromethorphan: CYP2D6 inhibitors, metoclopramide, MAOIs, naloxone, opioids, quinidine, serotonergic agents, or tramadol.

What is dextromethorphan?

Dextromethorphan (brand names: Delsym®, Robitussin®, Balminil®, Benylin ® and many others) is a medication used to treat compulsive behavior. It can also be used as a cough suppressant, although other cough suppressants are typically more effective in cats and dogs.

Its use in cats, dogs, and horses to treat compulsive behavior or cough is ‘off label’ or ‘extra label’. Many drugs are commonly prescribed for off label use in veterinary medicine. In these instances, follow your veterinarian’s directions and cautions very carefully as their directions may be significantly different from those on the label.

Dextromethorphan is given by mouth in the form of a tablet, gelcap, or liquid. It is also available in other forms, but these are more difficult to administer to pets. It may be given with or without food; however, if your pet vomits when given this medication on an empty stomach, give future doses with food or a treat. Measure liquid forms of this medication carefully. This medication will take effect quickly, in about 1 to 2 hours, and improvement in clinical signs should follow.

Are there any potential side effects?

Side effects are uncommon, but may include vomiting, diarrhea, decreased appetite, sleepiness, drooling, or anxiousness. More serious side effects include rapid heartbeat, collapse, muscle tension, incoordination, muscle twitches, seizures, and abnormal eye movements.

This short-acting medication should stop working within 24 hours, although effects can be longer in pets with liver or kidney disease.
