Welcome to Ask The Doctor.
You seem to be suffering from Upper Respiratory tract infection (URTI).
If you have severe coughing with sputum production, get a Chest Xray Done to rule out Pneumonia.
Claritin is Loratadine. If you are not getting relief with it then you might be having an acute infection.
For URTI, I advise as follows:
1. To take an antibiotic like Azithromycin.
2. To take an anti-allergic like Levocetirizine
3. To do warm saline gargles.
4. To do steam inhalation
5. To take Paracetamol on as or when required basis for fever and body pains.
Share my opinion with your doctor before you act upon it.
I hope it helps.
