Also try a shot of vitamin B12 complex and perhaps dexamethasone. Vitamin B helps for nerve damage, dex will help with any inflammation, which she may have if there's been nerve damage from her being down.
If her ears are cold, and/or if she's part dairy, and/or if she's a heavy milker and/or middle-aged (5yrs+), another tube of calcium gel might not be a bad idea. Meds given orally are not absorbed or used as efficiently by the body as meds given IV or systemically, so if she has a calcium deficiency, two tubes may not be enough. In cases of milk fever, my vet says he's done as many as 6 500mL bottles IV -- not something I'd chance, but it goes to show that on a downer due to calcium deficiency you can put a lot of calcium into them without causing problems. :P
