Almost 90% of headaches result from increased tension in the scalp and neck. Tension headaches (previously called muscle contraction or stress headaches) are usually described as a vise squeezing on both sides of the head or a tight band around the head. The pain can spread to the scalp, face, neck, and shoulder muscles.
Depending on the frequency, tension headaches may be chronic and episodic. Chronic tension headaches occur daily or almost every day, episodic tension headaches occur only a few times a week or month. Individuals who chronically have tension headaches often suffer from stress, anxiety, or depression as well.
Fioricet works best if you take it as soon as you feel a headache coming on. Most tension headaches go away within a few hours.
Fioricet is also used to relieve migraines. Many migraineurs find Fioricet useful when it is taken before lying down in a dark room.
