Most headaches go away within 12 hours with home treatment and the
use of nonprescription medications, such as acetaminophen, nonsteroidal
anti-inflammatory drugs, or aspirin.
Other headaches may require prescription medication for pain relief.
If your health professional has prescribed a medication for your headache, be
sure to follow his or her instructions for using the medication.
Rebound headache is a type of chronic headache that
can result from overuse of pain medications. This is often a problem for people
who have frequent, severe headaches. A pain medication may work for a limited
period of time, but as the effect wears off, the headache returns, often worse
than it was before. The person then takes more pain medication, the effects
again wear off, and the headache returns (rebound headache).
A headache that is not relieved by prescription medication may
indicate a more serious problem. Be sure to discuss this with your health
professional.
