Thanks for your question on Healthcare Magic.
I can understand your concern.
You are should do following things to reduce irritation from chemical gas inhalation.
1. Inhale fresh air from open space.
2. Drink plenty of fluids orally and keep yourself hydrated.
3. Do warm water gargles 5-6 times a day.
4. Don't panic, be relax and calm.
5. Take levocetrizine and
paracetamol combination twice daily.
You will mostly improve in 2-3 days with all these.
Watch for symptoms like excessive coughing, unbearable
chest pain and breathing difficulty. If any of these symptoms occur then immediately
consult doctor.
Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
