Precautions to Take When Administering Cerenia to A Dog

While a dog is being treated with Cerenia, It is essential to take specific safety measures to ensure that the medication will be administered to the dog in a manner that will be risk-free and effective. Take into consideration the following safety measures:

Follow Prescription Instruction 

Always follow the veterinarian’s instructions for dosing and administration of Cerenia. This will ensure the medication is administered appropriately and at appropriate intervals.

Lookout For Allergy Signs

Look for signs that might indicate an allergic reaction or other unpleasant consequences, such as your dog being lethargic, throwing up, or having diarrhea and other gastrointestinal issues. If you observe any of these warning signals, you want to contact a local veterinarian as soon as possible.

Be Mindful of Underlying Conditions

When administering Cerenia to a dog that has a problem with the liver or kidneys, exercise extreme caution since these diseases might alter how the body processes the drug. Do not give Cerenia to dogs with a known hypersensitivity to maropitant, the active ingredient in Cerenia. Your veterinarian may adjust the dosage or frequency of administration in these cases.

Be Cautious in Administering Cerenia

Cerenia should be used with caution in pregnant or nursing dogs, as the effects of the medication on developing fetuses or nursing puppies are not well understood. Consult with your veterinarian before administering Cerenia to a pregnant or nursing dog. 

Properly Store Cerenia 

Store Cerenia in a cool, dry place away from children and pets. Keep the medication out of your dog’s reach to avoid the risk of him eating it by mistake.

Use With Caution In Elderly Dogs

Dogs getting up there in age may be more susceptible to the negative consequences that Cerenia causes. Therefore, their veterinarian might recommend a lower dosage or less frequent dosing. Your pet’s veterinary practitioner can advise you on the appropriate dose for your older dog.

Avoid Abrupt Discontinuation

Only abruptly discontinue Cerenia after consulting with your veterinarian. Abrupt discontinuation can lead to rebound vomiting or other adverse effects.

Use With Caution With Other Medications

Cerenia may interact with other medications, such as pain medications, sedatives, or antacids. Keep your veterinarian updated on all drugs your dog is receiving.

Use With Caution in Dogs With a History of Seizures

Cerenia may lower the seizure threshold in dogs with a history of seizures. When delivering Cerenia to these dogs, exercise extreme caution, and watch for any indicators they could be planning an attack.

Do Not Crush Or Break Tablets

Cerenia tablets should be given whole and should not be crushed or broken. If you break or shatter the pills, the drug may be released too rapidly, making it more likely for you to have negative consequences.

Watch For Signs Of Dehydration

Cerenia can cause decreased water consumption in some dogs, leading to dehydration. Keep a close eye on how much water your dog consumes and be on the lookout for indications that he is getting dehydrated. These indicators include dry gums, lethargy, and less regular urination.
