Analgesia<unk> , like codeine, is a weak opioid, known to cause dependency among recreational users. Codeine is more commonly used; however, as codeine is, in essence, a prodrug that requires in vivo metabolism (to morphine via demethylation) for efficacy, it is ineffective for some individuals with the "poor metabolizer" genotype of the liver cytochrome P450 enzyme CYP2D6. In people with this low-function isoform,<unk>  is particularly useful, as its metabolism does not require CYP2D6. It is also used for patients with digestive complaints, as it is less liable to worsen their symptoms. Restless legs syndrome<unk>  has been found to be helpful in relieving the symptoms of restless legs syndrome. Opioid withdrawal In pure form,<unk>  is commonly used to ease the withdrawal symptoms in people addicted to opioids. Being very weak in comparison to commonly used opioids,<unk>  can only act as a "partial" substitute. It does not have much effect on mental cravings, but it can be effective in alleviating physical withdrawal effects, such as muscle cramps. Contraindications<unk>  is contraindicated in patients allergic to paracetamol (acetaminophen) or<unk> , and in alcoholics. It is not intended for use in patients who are prone to suicide, anxiety, panic, or addiction.
