What Is Codeine Linctus?

Codeine linctus is a cough medicine available in places like theU.K.andAustralia. The codeine linctus active ingredient is codeine phosphate. Although codeine linctus is not available in the United States, codeine phosphate is aSchedule II controlled substancein the U.S.

Codeine linctus works when someone’s central nervous system is overstimulated and leads them to feel like they need to cough. The reflex is blocked when the cough has no purpose (for example, you’re coughing because of overstimulation and not because you need to clear phlegm). The urge to cough occurs in your brain, specifically the brainstem. Opioids like codeine block this urge by working onmu and kappa opioid receptorsin the brainstem.

Codeine linctus comes in aclear oral liquid.

Codeine Linctus High

Codeine linctus can get you high because of the codeine. A high is particularly likely if someone takes larger doses of this drug. Codeine linctus is one of the less potent opioids, so the high wouldn’t be as significant as what a person might feel with other opioid prescription drugs.

Some people aregenetically more likelyto get high on codeine linctus than other people, due to an enzyme in the liver called CYP2D6. This enzyme breaks codeine down into morphine faster in some people than in others. This can lead to codeine taking effect more quickly than expected, leading to a high or an overdose in some cases.

Codeine Linctus Dose

General codeine linctus dose guidelinesinclude the following:

  • For cough in adults, the recommended dose is 15 mg (there are 15 mg in every 5 ml of the drug) every four hours, up to a max of four doses per day.
  • No codeine linctus dose is recommended for children because this drug has the risk of breathing problems and other complications.
  • A reduced dose may be needed in older individuals.

Codeine Drug Warning

Codeine linctuscan be habit-forming. For this reason, it is important to follow your doctor’s instructions for taking codeine linctus. Certain people are advised against taking it altogether,includingthose who:

  • Are addicted to opioids
  • Have liver problems
  • Have breathing problems, like slowed breathing or an acute asthma attack
  • Have serious bowel problems like paralytic ileus
  • Have increased pressure in their brains or a head injury
  • Break codeine down into morphine more quickly than expected
  • Are under the age of 18 years
  • Are breastfeeding

What Is Codeine?

Codeineis an opioid pain reliever narcotic. It is a controlled substance in the U.S. and many other countries. Codeine is anatural opioid, meaning that it is derived from morphine and is not chemically man-made. It is considered one of the milder opioids available: one milligram of codeineequates toroughly 0.15 milligrams of morphine.

How Does Codeine Work?

When you take codeine, your liver breaks it down into morphine. Then, it crosses into your brain and binds to opioid receptors. Opioid receptors can alter how you feel pain and reduce the urge to cough.

Opioids like codeine slow the function of the central nervous system, which can include essential functions like respiration. If you take too much of an opioid, it can slow your respiration to the point that youoverdose or stop breathing altogether, which is one of the biggest risks of these drugs.

Are There Any Risks to Taking Codeine?

Other risks of codeine-based products include physical dependence and addiction. With a physical dependence on codeine, a person has used the drug for a period of time until their body feels like it needs codeine to function normally. Then, if someone were to stop taking it suddenly after developing a tolerance, they would go throughwithdrawal symptoms.

Codeine and other opioids are so addictive because they trigger a release of dopamine and feel-good neurotransmitters when they enter the brain. This then starts a cycle of addiction: your brain compels you to continue seeking out whatever it was that released the brain chemicals that felt pleasurable, over and over despite negative consequences.
