My daughter is 9 and is taking amoxicillin for strep , she has a cough that won't stop so which kind of cough medicine can i buy otc for her ?

Persistent cough: Can be due to a cold , flu , allergies , sinus , virus, infection, chemicals causing postnasal drainage. You can certainly try giving her allergy meds like claritin, (loratadine) allegra. Zyrtec to see if it helps ease up the coughing. She can also take some expectorants to help thin out the thick mucus clogging up the airways. Drink plenty of warm liquids. If she suffers from asthma, she needs to see her doctor.

RobituscinDM/DELCYM: I presume she has been examined by md and does not suffer from asthma or allergic conditions.And cough is the only symptom and you need some over the counter cough medicine for symptom relief.Suggest 1extra fluids 2over the couner cough medicine containing an expectorant like guifanicin and cough suppressant like dextromethorphen robituscin dm delcym is 12 hour/ no expectorant discuss with md.
