Cough causes concern for parents and is a major cause of outpatient visits. Cough can impact quality of life, cause anxiety, and affect sleep in children and their parents. Honey has been used to alleviate cough symptoms. This is an update of reviews previously published in 2014, 2012, and 2010. ⋯ Honey probably relieves cough symptoms to a greater extent than no treatment, diphenhydramine, and placebo, but may make little or no difference compared to dextromethorphan. Honey probably reduces cough duration better than placebo and salbutamol. There was no strong evidence for or against using honey. Most of the children received treatment for one night, which is a limitation to the results of this review. There was no difference in occurrence of adverse events between the honey and control arms.

Cough causes concern for parents and is a major cause of outpatient visits. It can impact on quality of life, cause anxiety and affect sleep in parents and children. Several remedies, including honey, have been used to alleviate cough symptoms. ⋯ Honey may be better than 'no treatment', diphenhydramine and placebo for the symptomatic relief of cough, but it is not better than dextromethorphan. None of the included studies assessed the effect of honey on 'cough duration' because intervention and follow-up were for one night only. There is no strong evidence for or against the use of honey.

Review
Dextromethorphan: a review of N-methyl-d-aspartate receptor antagonist in the management of pain.
Dextromethorphan (DM) is a noncompetitive N-methyl-d-aspartate (NMDA) receptor antagonist, which is widely used as an antitussive agent. DM also prevents neuronal damage and modulates pain sensation via noncompetitive antagonism of excitatory amino acids (EAAs). DM has been found to be useful in the treatment of pain in cancer patients and in the treatment of methotrexate-induced neurotoxicity. Clinical studies with DM in cancer patients are reviewed in this article.

Most traditional opioids and non-steroidal anti-inflammatory drugs that are used to control perioperative pain have substantial side effects. The number of choices in clinical use was recently increased by two promising groups of drugs: N-methyl-D-aspartate receptor antagonists and central alpha2 agonists. One N-methyl-D-aspartate antagonist, dextromethorphan, blocks the generation of central pain sensation that arise from peripheral nociceptive stimuli by moderating the activity of N-methyl-D-aspartate. ⋯ Dexmedetomidine is a relatively new, highly selective central alpha2 agonist. Its sedative, pro-anaesthetic and pro-analgesic effects at 0.5-2 microg/kg given intravenously stem mainly from its ability to blunt the central sympathetic response by as yet unknown mechanism(s) of action. It also minimises opioid-induced muscle rigidity, lessens postoperative shivering, causes minimal respiratory depression, and has haemodynamic stabilising effects.
