Since you are 3 months
pregnant our aim is symptom control with maximum safety of the baby.
Now, you mention that you have both urticaria and rhinitis symptoms, with no history of fever, your nasal symptoms are most likely due to allergy.
Also the ear blockage which is accompanying is mainly due to nasal congestion causing Eustachian tube dysfunction.
Normally, the medicines that you are taking would be considered first line for your condition . But since you are pregnant, I would suggest to switch to safer alternatives.
Next Steps
-Best management is to start taking steam inhalation atleast thrice a day. This would help with nasal and ear issues both.
- start using saline nasal sprays thrice a day followed by budenase AQ Nasal spray after a gap of 10 minutes .
- Take Cetrizine 10mg once at night before sleeping.
