What is your protocol when your cat vomits shortly after being given meds?

Just curious about what protocol others follow when a cat throws up shortly after being given it's medication. It's an issue that most of us here have come up against.

(I came up against it again last night when my cat vomited cisapride and pepcid ac about 20 minutes after I gave it to her. I waited a fair bit until she had recovered, catnapped, and was asking for food, then gave her 1/8 tab pepcid ac instead of her usual 1/4 tab to help settle an obviously upset stomach. No cisapride. She's fine as can be this morning. Medicated and fed with no problem. Bad timing on my part last night, I guess.) 

If your cat vomits shortly after being given meds, do you wait a bit until the cat's stomach has a chance to settle, and then re-medicate? Or you do not re-medicate, wait for the next dosing time, and in the meantime hope for the best? A lot of it depends on the drug, of course. You certainly don't want to double dose your cat (depending the meds, it could be very dangerous and life threatening), but in some cases, it is best (or vital) not to miss a dose. All the while, you are wondering if it's a random act of vomiting or illness related. And then there is the issue of how long absorption of the drug takes, but if the stomach is basically refusing to absorb anything because it is about to get rid of everything ...

Thoughts, please.

Edit: and it's obviously something to ask your vet about when initially given the medication.

I usually wait for a bit.  Give them a little food (just a small bite if the med is supposed to be on an empty stomach).  Wait a bit more to make sure things have settled, then re-medicate.  If they throw up a second time, I wait for the next dosing time.

Sorry to hear this happened to Cocheezie last night.

Tim was throwing up periodically during the first six months he was on cisapride. I would normally wait a bit to see how he felt; if he seemed hungry, I took that to mean his stomach had settled and dosed him again. In his case, this always happened and I don't think we ever missed a dose in the first six months.

In late January, when he started throwing up every meal, I followed the same protocol but fed him much less food along with his medication when he appeared hungry. This went on for three meals before we went to the conventional vet, then late that same night, the emergency vet after profuse vomiting of food and stomach acid. This sequence of events, along with the discovery that he might also have "mild asthma", is what drove me to search for answers and ultimately caused me to look at everything I was feeding him and decide to wean him off cisapride (long story chronicled in the various threads I've started).

And you are absolutely right about this depending on so many things. When Tim was throwing up, I could see the blue capsule in his vomit, so knew nothing had been absorbed. If that blue wasn't there, or if it was only a lingering stain, I might not have been so quick to re-medicate. And even though I had been pestering the vet about reducing his dose, they still would not permit it and I was therefore very nervous about what might happen if he missed a dose. Today, because we skip two days between doses, I'm not sure what I'd do. But he's not vomited since early February (a record for him), so I hope I don't have to decide.
