Help! Breathing treatment of Albuterol, Decadron and Antivert (meclizine) almost 12 hours ago. Then shot of Methylpred right after. When is pulse going down???

A day or two? All of these medications can increase your pulse rate . If you have received Decadron shot plus Methylpred shots , the duration of the pulse rate increase is dependent on the total dose. Were you not on Toprol, (metoprolol) the pulse would likely have gone even higher.
