    Default Metacam - how long does a dose last?

    1.6Kg bun, using 0.6ml of 1.5mg/ml dog metacam.

    How long will that 'last' in her system?

    Everything i read differs, but i can't see how it could last more than 10-12 hours?

    Anyone?

    I have always been under the impression it lasts around 24 hours but I'm probably wrong. Dosage and bun size probably both play a part in how long its effective for as well. I know what you mean about it not lasting more then 12 hours, sounds like mostly.

    Clinical Pharmacology: Meloxicam has nearly 100% bioavailability when administered orally or after subcutaneous injection in dogs. The terminal elimination half life after a single dose is estimated to be approximately 24 hrs (+/-30%) in dogs regardless of route of administration

    Ugh, it says the same.

    I can't see how this small amount can be keeping her pain free for this long and she seems to get worse as the day extends

    Guess its back to the vets.

    I hope I'm not stepping on anyones toes with this, but Rhia has been on a huge dose for almost three weeks now with no adverse effects at all. I didn't continue with the 4ml a day as prescribed but she's had at least 2ml a day & a 3rd ml if she needed it (Alongside the Zantac). I know many people feel this is far too much but just to give an idea. Obviously in the longterm this may not be an option, but its worth a consideration X

    If she is getting worse as the day extends I'd be tempted to give an additional dose just before her usual 'lull'. Goes without saying to OK it with vet first

    If you know that she is in pain, then definitely contact your vet.

    There may be a shorter acting opiate that can be given between doses or metacam

    Left a message for her vet, as its his last day, just to see if he thinks she could have anymore, or if we should 'split dose' her.

    This refers to the elimination half-life in rabbits and says it's about 8 hours.

    I wonder if Ginger would be better having the meds split into two doses a day?
