Yes, Alice is right.
You are not supposed to open Omeprazole capules. Who ever told you this ok..... this is a false statement.
They do however make a packet form of the Omeprazole capules, which is safe to do that with then.
If you have difficulty swallowing the delayed-release capsules, you may add the contents of a delayed-release capsule to applesauce. Place one tablespoon of soft, cool applesauce in an empty bowl. open the delayed-release capsule and carefully empty all the pellets inside the capsule onto the applesauce. Mix the pellets with the applesauce and swallow the mixture immediately with a glass of cool water. Do not chew or crush the pellets. Do not store the applesauce/pellet mixture for future use.
When in doubt always check with your PCP is my best advice.
