Thank you for your question.
In most cases the cause for a cold, cough, and runny nose is due to viral infection.
In this case no antibiotic is needed and the disease is self limiting.
However if you develop fever, or sore throat, or yellowish sputum then do get examined by your doctor to know whether antibiotic is required.
At present, please keep yourself hydrated.
You may drink lots of water, juice, clear broth or warm lemon water
Chicken soup and other warm fluids can also be soothing and beneficial.
Saline nasal drops can be used and will help relieve nasal congestion.
