Re: Pergolide mesalate

Eleanor Kellon, VMD

Pergolide mesylate is a source of pergolide, just like sodium chloride (salt) is a source of sodium.

If you are trying to get a product from Wedgewood that is equivalent to the 1 mg tablet of Prascend you were using, you would need a prescription for 1.31 mg of pergolide mesylate which equals 1 mg of actual pergolide.

If your vet is going for a dosage increase, from 1 mg to 1.25 mg, you need 1.64 mg of pergolide mesylate.

= = = = = = = = = = =

For those of you that have horses which have only ever been on compounded pergolide and you aren't going to change, you don't have to do anything. Depending on the pharmacy you use, your 1 mg capsule may not truly be 1 mg of actual pergolide but if it is controlling your horse it doesn't matter.  Just realize that your dose is of pergolide mesylate, not pure pergolide, so if you need a dose increase it will be made in terms of pergolide mesylate.

I hope that doesn't confuse things further!
