For the symptoms of itchy throat coughing and weezeing what medication can I take?

Allergies/asthma. You may have allergies and/or asthma..Allergies can cause itchy throat, postnasal and hacking cough etc...Allergy meds such as claritin/zyrtec/benadryl may help. Nasal steroids are probably best, but need a prescription. Wheezing may suggest asthma and eval by doc is recommended. Asthma attack can be life-threatening and so please consult your doc asap... Good luck.
