What is omeprazole?
omeprazole oral capsule is a prescription drug that’s only available in the generic form used as a treatment for frequent heartburn. It is also known as an acid reducer drug. It is also available as an oral suspension and comes as an over-the-counter (omeprazole otc or Prilosec otc) medication. It is also sold in the brand names of Prilosec and Losec.
