What is Codeine Linctus?<\/h3>\n

Codeine Linctus<\/strong>\u00a0<\/a>(also known as Codeine Phosphate Linctus or Codeine Syrup) is a prescription-only oral liquid medication primarily used as a cough suppressant (antitussive). It’s formulated as a syrup containing\u00a0codeine phosphate<\/strong>\u00a0(typically 15 mg per 5 mL dose) dissolved in a sweetened, flavored vehicle, often with ingredients like glycerol, citric acid, and preservatives.<\/p>\n

Key Uses<\/h4>\n
    \n
  • Dry, irritating cough<\/strong>: Suppresses the cough reflex in the brain’s medulla oblongata, providing relief for non-productive coughs (e.g., due to colds, flu, or upper respiratory infections).<\/li>\n
  • Occasional mild pain relief<\/strong>: Codeine is a weak opioid analgesic, so it’s sometimes used for short-term pain management.<\/li>\n
  • Not for productive (chesty) coughs<\/strong>: It can thicken mucus and worsen conditions like bronchitis or pneumonia.<\/li>\n<\/ul>\n

    How It Works<\/h4>\n

    Codeine is a prodrug metabolized in the liver by the enzyme CYP2D6 into\u00a0morphine<\/strong>, which acts on mu-opioid receptors in the central nervous system to:<\/p>\n

      \n
    • Reduce cough reflex sensitivity.<\/li>\n
    • Provide mild analgesia and sedation.<\/li>\n<\/ul>\n

      About 5-10% of people are “poor metabolizers” due to CYP2D6 genetics, experiencing little effect.<\/p>\n

      Dosage (Adults, Typical)<\/h4>\n
        \n
      • Standard dose<\/strong>: 5-10 mL (15-30 mg codeine) every 4-6 hours, max 4 doses\/day (120 mg total).<\/li>\n
      • Children<\/strong>: Not recommended under 12; restricted use in 12-18 due to risks.<\/li>\n
      • Always follow prescriber instructions; shake well before use.<\/li>\n<\/ul>\n<\/div>\n

          Warnings & Contraindications<\/h4>\n
            \n
          • Opioid risks<\/strong>: High abuse potential; classified as a controlled substance (Schedule 5 in UK, Schedule II\/III elsewhere). Overdose can cause coma\/death\u2014naloxone reverses it.<\/li>\n
          • Do not use with<\/strong>: Alcohol, sedatives, other opioids (e.g., tramadol), MAOIs, or in acute asthma\/COPD.<\/li>\n
          • Pregnancy\/Breastfeeding<\/strong>: Avoid (passes into milk, risks neonatal sedation).<\/li>\n
          • Driving<\/strong>: Impairs; avoid until effects known.<\/li>\n
          • Overdose symptoms<\/strong>: Pinpoint pupils, confusion, blue lips\u2014call emergency services.<\/li>\n<\/ul>\n

            Availability & Regulations<\/h4>\n
              \n
            • Prescription-only<\/strong>\u00a0in most countries (e.g., UK, US, Australia). Not OTC due to opioid status.<\/li>\n
            • UK specifics<\/strong>: BP (British Pharmacopoeia) formulation; “Codeine Linctus BP 15 mg\/5 mL”.<\/li>\n
            • Alternatives<\/strong>: Dextromethorphan (e.g., Robitussin DM) for non-opioid cough relief; guaifenesin for expectorants.<\/li>\n
            • Street misuse<\/strong>: Sometimes abused for euphoria (“lean” with soda), but pure linctus is dilute.<\/li>\n<\/ul>\n

              Evidence & Sources<\/h4>\n
                \n
              • Supported by NICE guidelines (UK) for short-term cough suppression.<\/li>\n
              • Studies (e.g., Cochrane Review 2014): Modest efficacy vs. placebo for cough; better for nocturnal relief.<\/li>\n
              • FDA\/EMA warnings emphasize risks post-2017 codeine restrictions in kids.<\/li>\n<\/ul>\n

                Consult a doctor\/pharmacist before use<\/strong>. This is general info\u2014not medical advice.
