Breakthrough pain (BTP) is the pain that occurs between regularly scheduled doses of pain medication. It is a distressing symptom and needs prompt treatment. Unfortunately, studies have shown that although breakthrough pain is common in patients with advanced disease at home, medications to relieve it are not always prescribed. Patients in pain don't always use as much medication to treat their pain as is allowed.
Patients experiencing chronic pain are most often prescribed around-the-clock (ATC) doses of an opioid pain medication. Breakthrough pain shows up between these doses of the medication and often causes the patient great distress. It is important to be able to recognize BTP and keep an accurate record of it, so your health care provider, or that of a loved one you're caring for, can treat it properly.
Breakthrough pain has three basic categories: incident pain, spontaneous pain, and end-of-dose medication failure. It's important for your health care provider to recognize which type of BTP you are experiencing, since the treatment for each can be quite different.
Incident pain is pain that can be predicted and occurs with specific activities. An example of this is the patient who has pain every time he is turned from side to side for personal care.
Incident pain is often treated proactively. Because the pain is predictable, patients with incident pain can be pre-medicated with a quick-acting, short term-lasting pain medication before activities that cause pain. The dose may be adjusted based on the level and duration of activity expected to cause pain.
Spontaneous pain is unpredictable and not associated with any specific activity. Because of its unpredictability, it is often more difficult to treat.
Spontaneous pain is most often treated with a quick-acting, short term-lasting pain medication given as soon as the pain comes. Adjuvant medications may also be tried to offer better pain control. Adjuvant medications include anti-depressants, anti-seizure, and other medications that enhance pain management of some patients.
End-of-Dose Medication Failure
This is just what it sounds like -- pain that occurs toward the end of the time frame in which a medication dose is intended to be effective. For example, in a patient who takes extended release morphine every twelve hours, pain that occurs between the eighth and tenth hour is considered end-of-dose failure.
Treatment of end-of-dose failure may include shortening the interval between doses or increasing the dose of medication. For example, a patient experiencing pain at hour 8 while on a drug intended to offer relief for 12 hours may have the interval between doses decreased to every eight hours, or her dose may be increased by 25% to 50%.
Keeping a Record of Breakthrough Pain
The best way to make sure breakthrough pain is being adequately treated is to keep a thorough and accurate medication log. Keeping an accurate record of pain levels, medications used to treat it, and response to the medication will help a health care provider determine the best treatment. Your medication log may look similar to the one below.
