Do you know that antidepressant drugs are sometimes prescribed for individuals with out melancholy?

It’s true. Antidepressants are regularly prescribed for persistent ache, particularly ache associated to nerve illness (known as neuropathic ache), persistent low again or neck ache, and sure varieties of arthritis.

In truth, some pointers for the therapy of persistent low again ache and osteoarthritis (the commonest kind of arthritis) embrace antidepressants. One antidepressant particularly, duloxetine (Cymbalta), is FDA-approved for these situations.

Simply how antidepressants scale back ache is just not properly understood. One chance is that they have an effect on chemical compounds within the mind concerned in ache notion, a mechanism that differs from how they struggle melancholy.

Not often the primary alternative for ache aid

For individuals with persistent low again or neck ache or osteoarthritis of the hip or knee, an antidepressant remedy is just not often the primary therapy advisable. Different approaches, akin to bodily remedy, train, shedding extra weight, nonsteroidal anti-inflammatory medication (NSAIDs), or cortisone injections are often tried first. But when these aren’t useful, antidepressants akin to duloxetine or amitriptyline is likely to be an inexpensive subsequent step.

When prescribed for ache, the preliminary dose is often low (typically decrease than the beginning dose for melancholy). It’s steadily elevated if mandatory. Ideally, individuals discover a profit inside weeks of beginning the drug, and the remedy might be continued on the lowest efficient dose. Switching to a unique antidepressant could also be advisable if ache is just not properly managed, negative effects develop, or there’s an interplay with one other remedy.

A brand new examine suggests antidepressants don’t work properly for frequent varieties of ache

Previous analysis on antidepressants for persistent ache, akin to duloxetine for osteoarthritis of the knee, amitriptyline or duloxetine for persistent low again ache, and amitriptyline for chronic neck pain, demonstrated modest, short-term profit. However the research have been restricted: most trials have been small and lasted just a few months or much less. Notably, remedy negative effects, akin to nausea, constipation, and erectile dysfunction, have been frequent in these trials.

Now a 2021 study has mixed the info from previous analysis to get a greater sense of simply how secure and efficient antidepressants are for these situations. The information isn’t good:

  • On common, therapy with antidepressants minimally decreased ache and incapacity in contrast with placebo. The advance in ache — about 4 factors on a scale of 0 to 100 — was thought of too small to be noticeable.
  • Individuals handled with sure antidepressants for persistent ache typically stopped taking the remedy as a result of it didn’t work, induced unacceptable negative effects, or each.
  • Individuals with each persistent ache and melancholy didn’t expertise extra enchancment than individuals with persistent ache alone.

Sciatica could also be an exception: antidepressants might have decreased ache for as much as a yr. Nonetheless, the standard of the prior analysis was poor, so the examine authors weren’t assured about these conclusions.

These findings forged doubt on the usefulness of antidepressant therapy for these frequent causes of persistent ache. Nonetheless, they don’t rule out the chance that some people might get extra aid from these drugs than others.

The underside line

The obtainable proof means that, on common, the good thing about antidepressants for osteoarthritis or persistent low again ache and neck ache is modest at finest, and tends to be momentary. That’s disappointing as a result of, for a lot of ache victims, there are not any reliably efficient therapies (in need of joint alternative for osteoarthritis).

So, in case you’re on an antidepressant for ache and also you aren’t positive if it’s working, speak to your physician about whether or not you must think about stopping it. However don’t cease it by yourself. There could also be different causes your physician is recommending this remedy, and lots of antidepressants needs to be steadily decreased, not stopped all of sudden, to keep away from discontinuation symptoms.

If you happen to’re taking an antidepressant for ache, it’s price revisiting whether or not it’s actually doing something for you and whether or not it is likely to be time to shorten your remedy checklist. Not solely may you simplify your medical routine, you may additionally scale back the price of your medicines and the danger of medication-related negative effects.
