can dogs have zofran

If you’ve just got out of radiation therapy or surgery and are feeling queasy then Ondansetron can be quite useful. This medication, usually sold under the brand name Zofran, is a drug that is used to prevent nausea and vomiting. It does wonders in humans but what about our furry friends?

Can Dogs Have Zofran?

Yes, Zofran is safe for canine use. This antiemetic drug is used to treat severe vomiting and nausea in both dogs and cats. However, using Zofran in this way is ‘off-label’ or ‘extra label’. Giving Zofran is quite common in veterinarian medicine but it can be extremely dangerous to give Zofran to your dog on your own accord. So follow your vet’s directions carefully as their instructions may be significantly different from those on the label. Here’s everything you need to learn about this medication and what effects can it have on your pup.

How Does Zofran Work?

Zofran belongs to a class of drugs known as 5-HT3 receptor antagonists or serotonin blockers. The medicines in this group are used for the prevention and treatment of nausea and vomiting, particularly those caused by therapy. Zofran is one such medicine that works by blocking the action of serotonin. This disrupts the signal your body would usually send to your brain for the feeling of nausea, thereby reducing the likelihood of vomiting and nausea.

Zofran is believed to work the same way in your dog. It prevents them from feeling nauseous, making them unable to vomit.

Is Zofran Safe for Your Dog?

While there hasn’t been any extensive research conducted on dogs and cats to see if they could react to Ondansetron differently from us, it is generally believed to be safe for canine use. Most dogs can tolerate Zofran well and side effects are quite uncommon.

However, in some rare cases, Zofran can have some serious side effects, including abnormal heart rhythms and low blood pressure, which can cause fainting and severe lethargy. Dogs who are on certain medications or those who suffer from severe muscle weakness are believed to be at a greater risk of experiencing some of these side effects. This is why it’s important to consult your vet before deciding to use any form of medication for your dog.

Are There Any Risk Factors of Zofran for Dogs?

Before deciding to administer Zofran to your dog, there are certain risk factors that you need to consider. These include:

1. Some dogs could have Multidrug Resistance Mutation or MDR1, which makes them more sensitive to the negative effects of certain medications. This is most commonly seen in Australian Shepherds and Collies. In these cases, ondansetron should be used cautiously.

2. Like humans, dogs can be sensitive to certain allergens and ondansetron could be one of them. If your dog is allergic to it, you should avoid giving them Zofran.

3. It should be used cautiously in pooches with liver disease, gastrointestinal blockage, and heart rhythm abnormalities.

4. You should be cautious with giving Zofran to pregnant or lactating pets as we don’t know for sure if it could have any side effects.

How To Give Zofran to Your Dog?

Zofran is usually administered orally in the form of a tablet or liquid. You can give to your dog on an empty stomach, however, doing so can cause vomiting in some dogs. If this is the case for your dog, you can also give them Zofran with food or a treat like a peanut butter. However, if your dog refuses to take their pills, you can also find ondansetron in a gel form, or your vet can inject it into your dog for you.

After administering, Zofran will be effective in about 1 to 2 hours, and improvement in your dog’s condition should follow. The results of this drug are short-lived and therefore will cease to function within 24 hours.

What Are the Proper Doses of Ondansetron for Dogs?

Medication should never be issued without first consulting the veterinarian and as an owner, it’s your responsibility to consult your vet first if you have any queries related to your dog.
