I had fasting blood testing following euflexxa injection and had taken lisinipril, prevacid (lansoprazole) and zyrtec. alt was high at 92.could this be due to meds?

Unlikely: none of those medicines is particularly known for elevating your liver enzymes (the transaminases, including ALT), but liver toxicity is listed as a rare complication. It's unlikely that these are the cause of the slight ALT elevation. (but would consider discontinuing or switching if there was absolutely no other possible explanation for elevated ALT). Most common cause is moderate alcohol use.
