Most patients treated with either interferon or pegylated interferon experience flulike symptoms (fevers, chills, rigors, and myalgias). These symptoms may be mild to moderate in severity and usually occur with the first injection and diminish as the treatment continues. The flulike symptoms may be minimized by premedication with acetaminophen or a nonsteroidal anti-inflammatory drug. 

Nonsteroidal anti-inflammatory drugs (NSAIDs) may be initiated if acetaminophen therapy fails. At equipotent doses, all NSAIDs elicit similar analgesic and anti-inflammatory responses. Selection is based on patient preference, dosing frequency, tolerability, and cost. 

Simple analgesics such as acetaminophen and nonsteroidal anti-inflammatory drugs (NSAIDs) are first-line agents for treating OA (Table 55-2). 

Although generally well tolerated, CSFs may cause bone pain in around 25% of patients. This may be managed with acetaminophen or nonsteroidal anti-inflammatory drugs (NSAIDs), although attention to the platelet count is warranted with the use of NSAIDs. Sargramostim in particular may result... 

In addition to their beneficial effects, some medications may actually cause cellular injury and disease. An example of this phenomenon involves nonsteroidal anti-inflammatory drugs (NSAIDS). These drugs include aspirin (a derivative of salicylic acid), ibuprofen (arylpropionic acid, Advil ), and acetaminophen (para-aminophenol derivative, Tylenol ). Because of their beneficial pharmacological effects, consumption of these agents has increased significantly in recent years. NSAIDS have the ability to treat fever, pain, acute inflammation, and chronic inflammatory diseases such as arthritis. They are also used prophylactically to prevent heart disease, stroke, and colon cancer. 

Caffeine alone may produce analgesic effects in some forms of pain, but clinically it is most often used as an adjuvant medication (Laska et al. 1983 Ghelardini et al. 1997 Kraetsch et al. 1996 Forbes et al. 1991). It enhances the analgesic effects of nonsteroidal anti-inflammatory drugs such as acetaminophen and also speeds the onset of analgesia. It is effec-... 

Aspirin, acetaminophen, and many other nonsteroidal anti-inflammatory drugs (e.g., Advil) are inhibitors of cyclooxygenase, COX. 

The combination of MAOIs with meperidine, and perhaps with other phenylpiperidine analgesics, also has been implicated in fatal reactions attributed to the serotonin syndrome. Aspirin, nonsteroidal anti-inflammatory drugs, and acetaminophen should be used for mild to moderate pain. Of the narcotic agents, codeine and morphine are safe in combination with MAOIs, although doses may need to be lower than usual. 

Renal clearance of lithium is reduced about 25% by diuretics (eg, thiazides), and doses may need to be reduced by a similar amount. A similar reduction in lithium clearance has been noted with several of the newer nonsteroidal anti-inflammatory drugs that block synthesis of prostaglandins. This interaction has not been reported for either aspirin or acetaminophen. All neuroleptics tested to date, with the possible exception of clozapine and the newer atypical antipsychotics, may produce more severe extrapyramidal syndromes when combined with lithium. 

Dozens of combination products are available only a few of the most commonly prescribed are listed here. Codeine combination products available in several strengths are usually denoted No. 2 (15 mg codeine), No. 3 (30 mg codeine), and No. 4 (60 mg codeine). Prescribers should be aware of the possible danger of renal and hepatic injury with acetaminophen, aspirin, and nonsteroidal anti-inflammatory drugs contained in these analgesic combinations.

Since most codeine is dispensed as part of a compound preparation, potential side effects of the other drug(s) must also be considered. For instance, someone with stomach ulcers should not take codeine that is combined with a nonsteroidal anti-inflammatory drug (NSAID) such as aspirin or ibuprofen. Another type of risk from a compound preparation relates to codeine abuse. For instance, a person who abuses codeine might routinely take a dose of 100-200 mg of codeine to produce noticeable euphoria. Using Tylenol 3 to obtain this dose would also mean ingesting 1,000-2,000 mg of acetaminophen. Taking that amount of acetaminophen for any extended period presents a risk for liver damage, especially in combination with alcohol. 

Analgesics Analgesics or nonsteroidal anti-inflammatory drugs are often effective in mild-to-moderate migraine. Aspirin, acetaminophen, naproxen, propoxyphene, acetaminophen with butalbital, and caffeine are all effective in treating a migraine attack. 

Nonsteroidal anti-inflammatory drugs (NSAIDs) are helpful for early and mild headache. NSAIDs include acetaminophen, ibuprofen, naproxen, and others. A recent study concluded that a combination of acetaminophen, aspirin, and caffeine could effectively relieve symptoms for many migraine patients. One such over-the-counter preparation is available as Exedrin Migraine. 

After women have tried lifestyle changes, nutritional supplements, and nonpharmacologic treatment approaches, some may require pharmacologic therapies if there is limited response. Women with less severe PMS generally self-treat headaches and cramps with aspirin, acetaminophen, and nonsteroidal anti-inflammatory drugs (NSAlDs). NSAIDs, such as naproxen and ibuprofen, are the treatments of choice for dysmenorrhea, menstrual headaches or migraines, and mastalgia. 

Failure with acetaminophen warrants a trial with a nonsteroidal anti-inflammatory drug (NSAID).
