Hello,
Thank you for asking at HCM.
I went through your history and would like to make suggestions for you as follows:
1. As your hives started after taking Mucinex DM while having a
sore throat with earache, I would think of either the infection itself or Mucinex DM.
2. Although
amoxycillin is a very common cause of hives, I would not think of
amoxicillin you had hives even before taking amoxycillin.
3. At this moment, it is difficult to find the exact cause of hives, it could be Mucinex DM, viral infection or strep infection.
As you have already started amoxycillin,
throat culture will not be helpful. There are many possible viruses causing such symptoms with hives, so I usually do not advise my such patients to go for testing for viruses, especially because there are no
antiviral medicines for most of the viruses.
4. Were I treating you, I would suggest you to complete the course of Amoxycillin and take an antihistamine like
levocetirizine or cetirizine in morning and
diphenhydramine (Bendadryl that you are already taking, may cause sedation) before going to bed at least for 7-10 days.
If hives return after that, I would investigate my such patient for other causes of hives.
5. I would also suggest you to apply calamine lotion over the itchy areas. Please do not scratch the itchy areas as scratching would aggravate itching.
Hope above suggestions will be helpful to you.
Should you have any further query, please feel free to ask at HCM.
Wish you a very quick recovery and a very good health ahead.
Thank you & Regards.
