Which formulation should be used?
Owners should stick to using either the plain formula or children’s formula. Avoid using Claritin-D which contains the additional ingredient pseudoephedrine, as just 240 mg of pseudoephedrine could be lethal to small dogs and could cause unwanted stimulant-like effects in larger dogs. If you have accidentally given your dog Claritin-D, please contact the vet or the ASPCA pet poison hotline on (888) 426-4435 immediately.
If you’d rather avoid exposing your dog to the side effects of Claritin, use Derma-Ionx instead. Derma-Ionx is an effective natural remedy which provides fast relief from itching and skin irritation without the vomiting, diarrhea and urinary retention that’s possible when using Claritin.
Do not give this medicine to your dog without approval from your vet.
According to Dr. Fiona, Loratadine can be given to dogs at a dosage of 0.12 mg/lb to 0.22 mg/lb (0.25 to 0.5 mg/kg) to relieve allergy symptoms. The chart below shows a typical dose of 0.2 mg/lb:
Note that regular tablets contain 10 mg of loratadine per pill, while the children’s tablets contain 5 mg.
Can I Give My Dog Claritin?
Plain formulations containing loratadine as the only active ingredient can be safely given to a dog. Loratadine also appears to be safe when used in higher amounts. However, using Claritin-D which contains the ingredient pseudoephedrine could be very dangerous.
Pregnant Dogs: Because of the limited information regarding the use of loratadine during pregnancy it’s advised not to give this medicine to a pregnant dog. Instead, consider using similar medicines such as Zyrtec® which have shown to be safe for use in these circumstances.
Guidelines For Use
To ensure the safety of your dog during treatment you should always seek advice from your vet prior to use. Do not exceed the vet’s recommended dosage, and be sure to notify him or her of any medical conditions your dog suffers with, particularly liver disease. You should also tell the vet about any other medicines or supplements your pet is taking.
