What do they do?
Analgesics are drugs designed specifically to relieve pain. There are several types of analgesics: acetaminophen (Tylenol), which is available without a prescription, and a variety of opioid analgesics, which are available only with a prescription. Some products combine acetaminophen with an opioid analgesic for added relief.

How do they work?
Opioid (also called narcotic) analgesics work by binding to receptors on cells mainly in the brain, spinal cord and gastrointestinal system. Opioids are often very effective against pain, but they also carry a greater risk of side effects than acetaminophen.

Who are they for?
Analgesics are for anyone with pain, and that includes almost everyone with arthritis or a related condition. Doctors once reserved opioids for treating severe acute pain, such as that from surgery or a broken bone; however, in recent years, they have prescribed opioids increasingly for chronic pain, such as pain from arthritis. In fact, opioids are often the first choice of pain relievers for older people with chronic pain problems, because they have few effects on liver and kidneys. They may also be safer alternative to NSAIDs for people who cannot take NSAIDs to allergies or stomach problems, for example. Analgesics area also an appropriate, and possibly safer, choice for people whose arthritis causes pain but not inflammation.

But narcotic analgesics are not appropriate for everyone – particularly those at risk of addiction. Certain factors predict the suitability of long-term opioid use for individuals with chronic pain. A tool called DIRE (Diagnosis, Intractability, Risk and Efficacy) helps doctors to assess those factors – including the patient’s cause of pain, psychological health, chemical health and social support – by giving them a one-to-three score. A high composite score suggests the person is likely to gain the greatest benefits from opioid analgesics with the least risk of adverse effects.

What’s important to know about the drug class?
While some analgesics are taken as needed, others must be taken at regular intervals to keep down pain. If your doctor prescribes an opioid analgesic, be sure you know how to take it – and when. And never stop taking it abruptly because doing so can cause withdrawal symptoms such as anxiety, sweating, nausea and insomnia.

Although some people may benefit from taking acetaminophen in addition to an NSAID for added pain relief, you should always speak with your doctor before combining any medications, even those without a prescription. Also, it is important to speak with your doctor before combining an opioid analgesic and acetaminophen. Because many analgesic products already combine an opioid with acetaminophen, taking over-the-counter acetaminophen along with your medication could cause you to get a dangerously high dose.
