Is corsodyl gel, dangerous if swallowed? i take the dose as prescribed on the package. i didnt swallow much, only a tiny amount (swallow reflex )

Yes: If only a tiny amount, don't worry. Chlorhexidine is a very irritating chemical, and when used as a dental gel in this fashion, it would be impossible not to swallow a small bit no matter how well you rinse your mouth. Be careful with this product and use as directed

Not dangerous : the active ingredient is Chlorhexidine which is poorly absorbed when ingested orally even in large amounts according to GSK their manufacturer. The tiny/small amount you might ingest while using it would be very tiny and therefore harmless.
