[QUOTE="Lucky_P, post: 783815, member: 12607"] It's normal for it to become dark after opening and during prolonged storage; I would presume that it's a result of oxidation. If you read the label directions, it calls for storage at room temperature - not in the fridge; refrigeration probably doesn't hurt it, but it's not in accordance with the manufacturer's recommendation for storage conditions. If it is 'in date' and has been stored at the appropriate temperature, out of direct sunlight, and has not been contaminated by multiple in-and-outs with dirty needles, it should still be potent and effective(if the organism you're treating is susceptible to it), even if it is dark. Out of date and dark - or, out-of-date and clear in an unopened bottle - it's probably still effective, but may have lost some potency - but you don't know how much it may have lost; probably better to discard any out-of-date drugs, regardless of how expensive they are, and purchase new. But, I'll be the first to admit that I've used plenty of (reasonably) out-dated drugs - but not on client animals. Oxytet has a wide margin of safety - I'd much rather 'overdose' than underdose. Certainly has been known to cause some local tissue damage, hence the need to give it subcutaneously, in multiple sites, not more than 10-12 ml per site; I have, on occasion, given it intravenously. Liver damage? Show me the documentation. Have never seen that in print(except here), or heard it from a reliable source. [/QUOTE]
