Hi. Welcome to Just Answer. My name is***** I want to make sure I understand this situation completely. So this girl ate about 1/2 of a single 150 mg ranitidine pill? How long ago did this happen? Does she have any other health issues or is on any other medications?
That is good. This shouldn't be a bad situation. This drug is an H2 blocker and these are tolerated pretty well by canines. If 1/2 of a 150 was eaten, that gives a dose consumed of about 75 mg. A 22 pound dog is 10 kg's. So the mg/kg dose is 7.5 mg /kg. When being used for treatment, it is dosed around 1-2 mg / kg q 12 hours. A dose of 7.5 mg / kg isn't that much above this and really shouldn't be expected to cause any problems. There really isn't any need for specific treatment at this time.
