Osteoarthritis (OA) treatment is complex and multifactorial, with pharmacological regimens requiring sufficient flexibility to be adapted to individual disease progression, flare ups, and response to treatment. Coexisting conditions are common and can lead to problems regarding polypharmacy. Several guidelines have been published for the management of OA pain. ⋯ Finally, a UK patient survey, conducted at a London hospital (n = 200), found that 64% of patients were taking more than 1 drug for treatment of painful OA of the knee or hip; 76% were taking paracetamol and 40% were taking an NSAID. A further 39% had used an NSAID in the past but switched treatment, primarily due to side effects. These findings reinforce the case for the simple analgesic paracetamol to be seen as the cornerstone of pharmacological OA treatment, both as a first-line analgesic and as a foundation to which additional treatment modalities, including NSAIDs, can be added if and when necessary.

To assess the impact of individualized medication effectiveness tests (IMETs, or n-of-1 trials), on patients' short-term decision making about medications for chronic pain. Survey evaluation of patients undergoing a double-blind, crossover comparison of drug versus placebo, drug versus drug, or drug versus drug combination using paracetamol and ibuprofen in 3 pairs of treatment periods, randomized within pairs. General practice patients (supplemented by a few from 2 tertiary pain clinics) with either chronic pain (> or =3 months), or osteoarthritis (with pain for > or =1 month) severe enough to warrant consideration of long-term nonsteroidal antiinflammatory drug (NSAID) use but for whom there was doubt about the efficacy of NSAID or alternative. ⋯ IMETs provide useful information for clinical decisions. Paracetamol continues to be useful for patients with chronic pain whose optimal drug choice is in doubt. Our results provide a new (individual) perspective on the well-known recommendation for paracetamol as first-line treatment for chronic pain and demonstrate that it is feasible to provide IMETs nationally by mail and telephone.

Chronic pain is a significant public health burden. Several international guidelines and influential reviews recommend the use of paracetamol (acetaminophen) as the first-line analgesic of choice for the management of chronic pain. These recommendations are based largely on the balance of evidence, which favorably demonstrates the efficacy, safety, and low cost of paracetamol relative to other analgesics. ⋯ Today, the results of our investigations into the individualization of pain management options continue to support this suggestion. Based on the data available to date, it still seems prudent to use NSAIDs only in those patients in whom there is good evidence of improved efficacy over paracetamol. In patients with chronic pain, paracetamol can play an important role as an NSAID sparer, with resultant benefits in terms of reduced adverse effects and cost savings.
