Butalbital and Aspirin (Systemic)

Description and Brand Names | Before Using | Proper Use | Precautions | Side Effects

  • Analgesic

# In Canada, Aspirin is a brand name. Acetylsalicylic acid is the generic name in Canada. ASA, a synonym for acetylsalicylic acid, is the term that commonly appears on Canadian product labels.


Butalbital and aspirin combination is a pain reliever and relaxant. It is used to treat tension headaches. Butalbital belongs to the group of medicines called barbiturates . Barbiturates act in the central nervous system (CNS) to produce their effects.

When you use butalbital for a long time, your body may get used to it so that larger amounts are needed to produce the same effects. This is called tolerance to the medicine. Also, butalbital may become habit-forming (causing mental or physical dependence) when it is used for a long time or in large doses. Physical dependence may lead to withdrawal side effects when you stop taking the medicine. In patients who get headaches, the first symptom of withdrawal may be new (rebound) headaches.

Some of these medicines also contain caffeine. Caffeine may help to relieve 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.

Butalbital and aspirin combination is sometimes also used for other kinds of headaches or other kinds of pain, as determined by your doctor.
