Hycodan Overdose Symptoms and Treatment

According to, the brand name medicine, Hycodan, contains two medications, homatropine and hydrocodone. Hydrocodone is a narcotic cough suppressant (antitussive) that works on centers in the brain and prevents the urge to cough. Homatropine, a member of the drug class anticholinergics, counteracts hydrocodone to prevent an overdose of Hycodan. Hycodan is used for the relief of dry coughs, and it can also be used for other conditions as directed by your doctor.

What Is Hycodan?

“Hycodan is used for the relief of dry coughs, and it can also be used for other conditions as directed by your doctor.”
According to a Federal Drug Administration (FDA) summary review for regulatory action, Endo Laboratories, Inc. was initially approved to manufacture hydrocodone for use as an antitussive by the name Hycodan in 1943. According to a supplement in the journal American Health & Drug Benefits, a subtherapeutic amount of homatropine methyl bromide was added later. The purpose of this added medicine was to prevent overdose or Hycodan overdose symptoms. The FDA also states that Endo Laboratories, Inc. subsequently discontinued marketing both the tablet and liquid form of Hycodan in 2008. Neither safety nor efficacy was the reason for the discontinuation. states that Hycodan is not indicated for children younger than six years. states that prior to using Hycodan, you should tell your doctor if you have any of the following:
