You can take codeine cough medicine with Deslym and Allegra D if your cough is consistent.
Also use a humidifier in your room.
Elevate your head side of bed.
Hydrate yourself with warm liquids.
In case your symptoms get worse over the time even after taking medications then it's good to visit ER.
I hope this helps.If you have any further query then feel free to ask.Positive feedback and bonus are highly appreciated.Thank you.
