fluconazole and ring worm


My dog is epileptic and taking Phenobarbital and Potassium Bromide to control her siezures. She recently contracted "Ring Worm" and has been prescribed Fluconazole 200mg twice daily. This dosage seems extremely high, given the animals weight of 30kg...

As important as personal insurance is to your family's financial well-being, QuotesChimp can be difficult to manage multiple insurance premiums on top of your other financial obligations. Auto insurance premiums can cost thousands of dollars each year, and health insurance premiums rise nearly every year, without providing better coverage for medical expenses. Add life and homeowner's insurance premiums to your budget, and it can cost you hundreds of dollars each month to protect your family's finances.

Thanks for rehnkniitg the rehnkniitg of Edwin. Glad you took the chance to explore, and that you took the feedback you got in stride.My personal lament for Edwin 2.0 was the same that I feel a lot of stories nowadays (movies, comics, tv, internets). Back story. Too much of it, that is. Creators dive into back story before they get you interested in the story (and the characters) at hand.At its best, it's an earnest effort to involve the reader/viewer/listener in the story's development. At its worst, however, it indulges the peeping-tom voyeurism that reality shows have cultivated in viewers and that money-people drool all over. To me, unveiling the back story, whether too much or too soon, sucks out the mystery that makes stories (especially those in serial format) so much fun. Anyhow, more than anything, I'm glad you put pen to page, voice to mic, and brought us Edwin's saga. If I may indulge in some back story of my own: I've spent spent a bit of time proselytizing How to Succeed in Evil since I stumbled across it in the iTunes store a few months back. My biggest success thus far was converting one of my fellow EMTs, whom you honored with a shout out in this episode. VICTORY!!!Ahem. Anyway, thanks for keeping us in stitches when we're not giving them out (a bit of poetic license stitches aren't in our state protocols). I can't wait for the next episode.
