Lorcet is the brand name for hydrocodone, a potent narcotic analgesic, and acetaminophen, a non-narcotic pain reliever. That same combination is also marketed as Lortab, Vicodin and Norco. It is meant for the treatment of moderate to severe pain. It can also be used to suppress chronic cough.

Effects on the Body
Lorcet can cause effects that include nausea, constipation and euphoria. This and other narcotic medications can also lead to other problems including tolerance, physical and psychological addiction, overdose and the need for medical detox. The opiate-based painkiller carries a label that spells out instructions on use, information on allergic reaction, possible interactions and other warnings. Not every patient will experience the same side effects with Lorcet. For some, effects will begin soon after the first dose. For others, the onset could take longer.

Lorcet can cause effects that include nausea, vomiting, sedation, euphoria, lightheadedness, vision changes, mood changes, dizziness, fatigue, depression, tremors, sleeplessness, anxiousness, flu-like symptoms, upset stomach, dry mouth, pupil constriction, itching, hallucination, delirium, sweating, muscle and bone pain, confusion, extreme irritability and muscle spasms. Medical help should be sought immediately if patients experience any of these more serious side effects: severe respiratory depression, slow or irregular breathing, slowed heart rate, hearing loss, changes in the amount of urine, confusion or stupor, coma, clammy skin, circulatory collapse and cardiac arrest. Acetaminophen can also cause liver damage in excessive amounts. Signs to watch for include yellowing of the skin or eyes, severe nausea, dark urine, stomach pain or extreme drowsiness.
