Butalbital, acetaminophen, and caffeine combination is used to relieve symptoms of tension (or muscle contraction) headaches.

Butalbital belongs to the group of medicines called barbiturates. Barbiturates act in the central nervous system (CNS) to produce their effects.

Acetaminophen is used to relieve pain and reduce fever in patients. It does not become habit-forming when taken for a long time. But acetaminophen may cause other unwanted effects when taken in large doses, including liver damage.

When butalbital is used for a long time, it may become habit-forming, causing mental or physical dependence. However, people who have continuing pain should not let the fear of dependence keep them from using narcotics to relieve their pain. Physical dependence may lead to withdrawal side effects if treatment is stopped suddenly. However, severe withdrawal side effects can usually be prevented by gradually reducing the dose over a period of time before treatment is stopped completely.

Caffeine is a CNS stimulant that is used with pain relievers to increase their effect. It has also been used for migraine headaches. However, caffeine can also cause physical dependence when it is used for a long time. This may lead to withdrawal (rebound) headaches when you stop taking it.

This medicine is available only with your doctor's prescription.

Management of generalized tonic-clonic (grand mal) seizures.

Management of partial seizures with complex symptomatology (psychomotor and temporal lobe seizures).

Not recommended for treatment of pure absence (petit mal) seizures since the drug may increase frequency of these seizures, but may be used in conjunction with other anticonvulsants when mixed seizure types are present.

Prevention and treatment of seizures occurring during and following neurosurgery.

Used IV for treatment of status epilepticus; however, use may be limited by its slow onset of action and need for slow administration.

Benzodiazepines (e.g., diazepam, lorazepam, midazolam) are considered drugs of choice for initial treatment of status epilepticus; IV phenytoin (or fosphenytoin) may be used as a second-line agent if seizures continue.

Concurrent administration with an IV benzodiazepine or short-acting barbiturate will usually be necessary for rapid control of seizures.

Fosphenytoin appears to be better tolerated than phenytoin, and some experts state that fosphenytoin is preferred when both drugs are available.

Has been used IV for treatment of cardiac arrhythmias, particularly ventricular arrhythmias, in patients who do not respond to conventional antiarrhythmic agents or cardioversion. However, current use as an antiarrhythmic agent is limited by the drug's narrow therapeutic window, multiple drug interactions, and adverse effect profile.

Has been used IV for treatment of arrhythmias caused by cardiac glycoside intoxication, especially in the presence of AV block, because the drug improves conduction through the AV node.
