I have taken Methylprednisolone for the hives. The prescription was for 21tablets. 6 on day one, 5 on day two, etc. The hives are gone but one the very last day of taking the medication ( one last tablet), I became dizzy. The dizziness has recurred of and on for the past three days. If I remain still it is not a problem but when I bend my head down in brings on the dizziness. What do you recommend?
