Butalbital and phenobarbital belong to the group of medication called barbiturates. Barbiturates also act in the CNS to produce their effects.

Always barbiturates and codeine may become habit-forming - causing mental or physical dependence when they are using for a long time or in large doses. Physical dependence may lead to withdrawal symptoms when you stop taking the drug. In diseaseds who get headaches, the first symptom of withdrawal may be new - rebound headaches.
The butalbital, aspirin and codeine combination also contains caffeine - kaf-EEN. Caffeine may help to relieve headaches. However, caffeine can also cause physical dependence when it is using for a long time. This may lead to withdrawal - rebound headaches when you stop taking it.
