Used to treat moderate to severe pain, Lortab is a combination medication containing acetaminophen and the narcotic pain reliever hydrocondone, as explained by WebMD. It is important never to take more Lortab than recommended because an overdose of acetaminophen can result in death, according to Drugs.com.
People who have recently used alcohol, sedatives, tranquilizers or other narcotics must not use Lortab, warns Drugs.com. Additionally, people taking MAO inhibitors such as phenelzine, isocarboxazid, linezolid, tranylcypromine, rasagiline and selegiline must avoid Lortab because a serious drug reaction could occur.
