Hydrocodone/apap 7.5 mg/325mg is an opioid analgesic used to relieve moderate to severe pain, according to WebMD. The medication is usually taken in one-tablet doses every 4-6 hours, and not to exceed 6 tablets daily.
Hydrocodone is a combination medication containing narcotic (hydrocodone) and non-narcotic (acetaminophen) pain relievers. Hydrocodone works by changing the way the body responds to pain, while acetaminophen reduces the pain and fever.
The drug is administered with a warning that overuse may become habit-forming and has been associated with acute liver failure, explains Mayo Clinic. Alcohol, other narcotics, antihistamines and antipsychotics should all be avoided when taking the drug.
