Cold medications and Synthroid?

Question

I have hypothyroidism and take 0.075 mg of Synthroid every day. I have had a very bad cold for the past week and I bought Otrivin and a cold medicine that contains 30 mg of pseudoephedrine hydrochloride, 15 mg of dextromethorphan hydrobromide and 500 mg of acetaminophen per tablet. Is it really serious if I took both of these medications? Have I unbalanced my thyroid gland? What other alternative do I have to relieve my cold symptoms (congestion, cough, headache) if I can't take the two medications mentioned earlier? Thank you for your help! Hello, No, that's all. Thank you for your answer! :) [name removed for privacy]

Hello, thank you for your question. It is not recommended to combine Otrivin and the cold medication you mentioned because both contain a decongestant. Given your symptoms I suggest you take the tablet and stop the Otrivin. Don't worry, these medications will not offset the effect of your Synthroid I also suggest a saline solution for cleaning your sinuses (Hydrasense or Sinus Rinse), which can be used as many times a day as desired (at least 1 hour before bedtime though). Do you have any other questions? We look forward to seeing you!
