Thank you for your query at DoctorSpring.com
Dry cough without any phlegm is a sign of allergy induced coughing.
You can take the following medicines :
1) Syp. Ascoril 2 teaspoons twice daily for 5 days.
2) Tab. Levocetrizine once at bed time for 3 days.
Start the medicines and let me know it is getting better.
Patient replied :
Hi Thanks for your updat.. But I am following treatment for Pregansy, So by taking Levocetrizine will affect anything ?
You meant you're pregnant I presume.
Yes both the medicines I recommended are safe to be used in pregnancy.
