Breakthrough pain and when to take the extra dose

It helps to know that clinicians sort pain into categories, because the category shapes the plan.

NCI describes three. Acute pain "may feel sharp and come on quickly. It often lasts for only a short time." Chronic pain, "also called persistent pain, is pain that usually lasts more than three months." And breakthrough pain "may come on suddenly, is pain that may occur while you are taking medicine to manage chronic pain."

That third one is the subject here. The name describes exactly what it does: it breaks through a wall of medicine that is otherwise holding.

If your ongoing pain is being managed with regular medicine, the plan assumes a fairly steady level of pain. Real life is not steady. Moving, coughing, getting dressed, a long car journey, the end of a stretch between doses — any of these can produce a spike the background medicine was never going to cover.

Rather than raising the regular dose enough to flatten every spike, which would leave you over-medicated the rest of the time, most pain plans include something extra for those moments.

Here is the honest position. How long you should leave between your regular pain medicine and an extra dose is a prescription detail. It depends on which drugs you have, in what form, and at what strength. There is no single number that applies to everyone, and NCI's general pain guidance for patients does not offer one.

So the useful thing this page can do is tell you to get that number and write it down. Ask your prescriber or your pharmacist:

• How long after my regular dose can I take the extra medicine?
• How long must I wait between extra doses?
• What is the most I can take in a day?
• At what point should I stop taking more and phone you instead?

Keep the answers somewhere you will find them at three in the morning, which is when the question actually comes up.

A pain plan you cannot recall under pressure is not a plan. Get it written down.

Whatever the interval turns out to be, NCI is clear about the general principle: "Don't wait until your pain gets bad before taking pain medicine. If you wait to take your medicine, the pain may take longer to go away, or you may need to take more medicine."

And more broadly: "The best way to control pain is to stop it from starting or keep it from getting worse."

Many people do the opposite. They wait, hoping it will pass, or worrying about taking too much, or wanting to prove they can manage. NCI's guidance points out that this backfires — the pain simply becomes harder to bring down.

If you know an activity reliably causes pain, ask your team whether taking something beforehand is part of your plan. That is a reasonable question, not an attempt to get extra medicine.

Your team can only adjust what they can see. NCI suggests asking your nurse how to track pain-related information, and notes that some people write down their levels of pain and the medicine they took for it in a notebook.

A record does not need to be elaborate. Time, a number out of ten, what you took, and whether it worked is enough. Over two weeks a pattern usually emerges — pain always at the same hour, or always after the same activity — and that pattern is exactly what lets a prescriber change the plan intelligently instead of guessing.

NCI puts it plainly: "Tell your health care team how the plan to control pain is working. Trying to 'deal with' the pain can make it harder to control in the future."

Needing extra doses regularly is not a failure and it is not something to hide at your next appointment. It is a signal that the background plan may need changing, and that is a thing your team knows how to do.
