Dicodid is a brand name for a drug that contains the narcotic pain relief medication called hydrocodone. Other synonyms for dicodid include the drugs Vicodin, Lortab, Norco, and Hycodan. These are all painkillers that are used to treat moderate to severe pain in patients suffering from various conditions such as arthritis, cancer, or post-surgical pain.

It is important to always follow your doctor's instructions when taking any pain medication and to only use them for as long as necessary.
