<unk>  is effective for prevention of shivering during surgery or recovery from surgery.<unk>  was significantly more effective than aspirin as an analgesic in one clinical trial, although with a greater incidence of side effects such as sweating, dizziness and nausea, especially at higher doses. The estimated relative potency of<unk>  to morphine indicates that 20 mg of<unk>  HCl is the approximate analgesic equal of 12 mg of morphine with comparable analgesic efficacy to morphine, or oxycodone, while<unk>  tends to produce fewer side effects, does not produce respiratory depression, and has much less abuse potential, and so is useful either as an alternative to opioid analgesics, or as an adjunctive treatment for use alongside opioids or other types of analgesics.<unk>  is also used to treat severe hiccups.
