Hi & Welcome.
It is unfortunate that you accidentally swallowed mosquito repellent odomos cream.
At the outset, I am of the opinion that since you rinsed your mouth and spat it out immediately there is less chance of it causing harmful effects.
However, this mosquito repellent has a chemical which can cause breathing problem,
vomiting, stomach pain, seizures as well.
I would advice the following detoxifying measures:
1. Firstly, remove all source of the cream from your body.
2. Remove clothes which may be contaminated with the cream.
3. Wash your month and lips thoroughly with plain water.
4. You can drink a glass of water or milk to reduce possible absorption from what has been swallowed.
It is preferred to visit a doctor or emergency room immediately you will be assessed and if required stomach wash will be done.
If you cannot go to the hospital for unavoidable reasons and have taken less quantity, you can drink a glass of milk if vomiting has not yet occurred.
If you develop any vomiting, seizures,
abdominal pain etc. do go to the hospital immediately.
Wishing you best of you health.
A feed back is appreciated.
