<s>[INST] Hi, around 50 to 60 ml of undiluted dettol was spilt on my mattress. I have been exposed to it for roughly 12 hours.I just saw the label that indicates dettol as a toxic substance. What are the effects of inhaling dettol fumes, does it cause any brain damage, and should I change my mattress? [/INST] Thanks for your question on Chat Doctor. I can understand your concern. No need to worry about this. Detail does not cause effervescence and hence no fumes. You are only taking smell of detail. It is not harmful for the body. Detail is harmful if applied internally or on mucosa like in mouth, vagina, Penis, nose, ear etc. No need to worry in your case. But if you develop coughing, breathlessness, chest pain than consult doctor. Otherwise, no need to worry. And yes, you should change the mattress. Hope I have solved your query. Wish you good health. Thanks. </s>
