welcome to hcm,
I really appreciate your concern,
yes
cetrizine is one of the safest medicine used for
sinusitis, which can be used with other medications.
with appropriate measures and medications, sinusitis can be solved.
My suggestions to you are:
1. Drink plenty of warm water.
2. Do steam inhalation 2-3 times in a day. Steam helps in reducing the
nasal congestion and relieving the nasal and ear block.
3. Try using saline
nasal spray as frequently as possible. Saline spray keeps the nose moist and free of pain and bleeding.
4. If there is any thick discharge, you can add a mucolytic (such as ambroxol or
bromhexine).
5. Finally, avoid chilled food and beverages/coffee/smoking.
Please let me know if you have any questions,
thanks.regards.
