This is probably pretty basic but I used some nausea remedy for Gabby in January, mixed some up and kept it in the refrigerator. Is it still good? JJ threw up at 5AM this morning, all food consumed 10 hours prior, and has been "down for the count" all day long, staying outside for 6 hours from 8-2PM. He seems a bit out of it. Not interested in eating but drinks water. He has thrown up in the past and never seemed to be lethargic this long. I was going to give him some nux vomica and gastruccomeel I had mixed up. It looks like there are some particles in it. So I don't know if it is still viable since January. Thanks
