<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am a 65 yr. old female. have had a chronic cough with phlegm, some wheezing when I exhale Thishas been going on for about 3 weeks. I have Hashimoto Thyroid with goiter, take Armour 30 mg. daily. Have allergies to dustmites, pollens. Just now I got into a cought fit and had a very strong metallic aftertaste..something new with this! I take Claitan D daily, and last night, 2 benedryl. What can do tonight to calm this down? I have access to antibiotics, but have not taken any.  <response>: Hi, I have gone through your query. From your history it seems to an Upper respiratory tract infection. Symptomatic treatment will help you temporary. You will require a course of antibiotic like Levofloxacin 500 mg twice daily or azithromycin 500 mg once daily. Instead of Clarity D you should take Manticore montelukast and Levocetrizine. You can continue with your thyroid medications. Do consider positive feedback as a credit to my work. Let me know if you have any further questions.
