Dental work and hives

I get hives every time I have dental work lately.  Currently have Clindamycin.  How many days prior should I start this and how many days after should I continue?

   Sorry I can't answer your question about the medication, but do you know WHY you get hives? That's rather important. I wonder if you might be allergic to the latex of the doctor's gloves....

Hey, Heymore, why would you take a powerful antibiotic that is linked with Cdiff infection because it wipes out the good bacteria because you get hives?  Hives are an allergic reaction, and since it happens at the dentist's office, number one on the list is latex rubber sensitivity.  Have the dentist wear non-latex gloves and avoid latex and see if you still get hives.  And did you know that wiping any areas in contact with latex on your skin will deactivate the latex?  Rinse with a mouthwash containing alcohol.  Some metals will also produce hives.  There are type I and type iv reactions, and in the past few years they have discovered that there can be delayed reactions to the protein in latex, not just to the chemical accelerants.  How soon after the dental visit do you get the hives?
