Famotidine 10 mg
My cat has kidney failure and was being given a tiny dose of famotidine by the vet....10 mg spread over 15 days, in cherry syrup....to help with her vomiting. While it was helping her control her upset stomach, a change in management at the vet coupled with a 400% increase in price, made me want to seek out alternatives.
After reading the dosing instructions for this product, I realized that I could provide Sinclair with a much more concentrated dosage myself...simply by investing some time in cutting up the 10 mg tablets into quarters & grinding them. I mix the powder with some water and give it to her with an oral syringe.....she doesn't complain and her stomach has been so much better than it ever was with the vet's meds.
Thank you, thank you!
Famotidine will not work as well if it is given with food. It is important to always give the medication on an empty stomach. I recommend giving the medication 30 minutes before you feed your pet a meal or before bed.
This product is useful in the treatment and prevention of gastric (stomach) and intestinal ulcers. If your furry pal is passing gas and nothing such as the food or feeding times have been changed this product can help. But if the problem does not go away please contact your vets office.
I thought the vet said to give my dog which is about 8 pounds a pill of famotodine (the 10mg, not the 20mg) so I did. I just googled it and see that the dose should be less than 5mg for a dog his size. Is this going to hurt him? He's been vomiting repeatedly due to something he ate which he shouldn't have though it was very little of it (some pizza hot pocket grease and melted shredded cheddar cheese (not much was on the plate though). Please let me know if I need to induce vomiting or watch for signs of overdose.
You should call your veterinarian about this overdose. An 8 pound dog would usually take about 3.5 mg as a maximum dose. Symptoms of famotidine overdose may include vomiting, restlessness, pale gums, rapid heart rate, or collapse.
