Yes, particularly with stubborn infections. Baytril and doxycycline are often used together.

Ugh! I didn't look at the dosage until I got home tonight. The doxy was/is 0.15 ml, which is 1.5 on the syringe. The Baytril says 1.2 mls. This would be a full syringe and another .2.

I don't recall ever giving this sort of volume before, and I was afraid to give him that much tonight. The only other info on the bottle is: Baytril 68 mg. Give 1.2 mls every 12 hrs. Does this sound OK? The vet is closed until 8 am tomorrow.

It looks like they have the decimal in the wrong place. The strength is 68 mg/ml? I haven't used a liquid form of Baytril with our guys -- just tablets. Let me see if I can calculate that out for you. What is his weight?

I would not say it is common but it is still sometimes done.

Looks like Baytril has a range of 5-20 mg/kg. The calculation for a dose of any medication is the recommended dose per kg x weight of the guinea pig (in kg) divided by the suspension of the medication (mg/ml).

If we go with a middle-of-the-road dose of 10 mg/kg, and if he weighs around 1 kg, it would be 10 mg/kg x 1 kg of weight = 10 / 68 mg/ml = 0.147ml as the dose. Somebody here please double-check my math.

I'd absolutely call your vet first thing and verify this, but from where I'm sitting, I'd say it was a typo.

He is close to 3lbs., like 2.10, I think. They have his weight and he's put to bed for now, so I can't get him on the scale til tomorrow. The bottle only says 68mg. and 1.2 mls twice per day. The bottle of Baytril is a lot bigger than the doxy, so the volume per dose would much bigger, but I'm clueless now. I held off on the Baytril for tonight and will call them first thing in the am. Thanks all!

At his weight, and at 10mg/kg, his dose would be more like 0.18cc's. I can't imagine a dose anywhere NEAR what they have on the bottle. If you can find out the exact strength of the medication (is it 68mg/ml?), we can make sure the dose is correct.

I missed that. Yes, 68mg is pretty high.

One common concentration is a 2.27% solution (22.7mg/ml).

So, I heard back from the vet office. I didn't get to speak with the vet herself. Basically, the label was wrong. Rather than 1.2 twice a day, it should be .6, twice per day. Now I recall the last time I used Baytril the dose was like, .4 1/2 to .5 twice a day. The person I spoke with couldn't explain the dosing. She said she thinks the calculation is 5mg/ml. I don't know what that means, but I suppose I will try the .6 dose for now. I don't know why their dose and your numbers seem so far off. Could it be that their concentration is low, so the volume is greater? She did say this is the lowest dose they get from their supplier.

It still doesn't make sense, but that sounds like a more reasonable dose. We'd need to know for sure what the concentration is in order to double-check the dose.

Are you talking to some from the front desk, or to a vet tech? If you're talking to a desk clerk, I'd call back and ask to speak to someone who works in the back and actually knows something about meds.
