I take levothyroxine. My allergies are terrible and unfortunately, it seems like every allergy medication I've ever heard of has major potential side effects when combined with levothyroxine.
I suggest Benadryl, it does not interact with your medication, it does not have many possible side effects and it is and it is available both RX and OTC.
Benadryl is used in the treatment of allergic reactions; extrapyramidal reaction; cough; cold symptoms; hay fever (and more), and belongs to the drug classes anticholinergic antiemetics, anticholinergic antiparkinson agents, antihistamines, miscellaneous anxiolytics, sedatives and hypnotics.
Before taking it , if you decide to take it, run it by your Dr. first.

The timing of meals relative to your levothyroxine dose can affect absorption of the medication. Therefore, levothyroxine should be taken on a consistent schedule with regard to time of day and relation to meals to avoid large fluctuations in blood levels, which may alter its effects. In addition, absorption of levothyroxine may be decreased by foods such as soybean flour, cotton seed meal, walnuts, dietary fiber, calcium, and calcium fortified juices. These foods should be avoided within several hours of dosing if possible. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor. When levothyroxine is given during continuous enteral nutrition (tube feedings) for more than 7 days, the tube feeding should be interrupted for at least one hour before and one hour after the dose of levothyroxine. You may need more frequent blood tests to monitor levothyroxine levels.
