What should I know about storage and disposal of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet.

See the FDA’s Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
In case of emergency/overdose
In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at https://www.poisonhelp.org/help. If the victim has collapsed, had a seizure, has trouble breathing, or can’t be awakened, immediately call emergency services at 911.
While taking it , you should talk to your doctor about having a rescue medication called naloxone readily available (e.g., home, office). Naloxone is used to reverse the life-threatening effects of an overdose. It works by blocking the effects of opiates to relieve dangerous symptoms caused by high levels of opiates in the blood. Your doctor may also prescribe you naloxone if you are living in a household where there are small children or someone who has abused street or prescription drugs. You should make sure that you and your family members, caregivers, or the people who spend time with you know how to recognize an overdose, how to use naloxone, and what to do until emergency medical help arrives. Your doctor or pharmacist will show you and your family members how to use the medication. Ask your pharmacist for the instructions or visit the manufacturer’s website to get the instructions. If symptoms of an overdose occur, a friend or family member should give the first dose of naloxone, call 911 immediately, and stay with you and watch you closely until emergency medical help arrives. Your symptoms may return within a few minutes after you receive naloxone. If your symptoms return, the person should give you another dose of naloxone. Additional doses may be given every 2 to 3 minutes, if symptoms return before medical help arrives.
Symptoms of overdose may include the following:
- difficulty breathing
- slow or shallow breathing
- excessive drowsiness or sleepiness
- unable to respond or wake up
- loss of muscle tone
- cold and clammy skin
- slow heartbeat

1. How it works
Codeine is an opioid analgesic (pain-reliever) that is related to morphine.
Codeine works by weakly binding to a specific opioid receptor, known as the mu-opioid receptor, but with much less affinity than morphine, which means its analgesic (pain-relieving effects) are much less.
Codeine belongs to the group of drugs known as opioids or opioid analgesics. Codeine may also be called a narcotic analgesic.
May be used to treat mild-to-moderate pain that is unrelieved by nonopioid analgesics.
Generic codeine is available.
If you are between the ages of 18 and 60, take no other medication or have no other medical conditions, side effects you are more likely to experience include:
how long does lean stay in your system
Note: In general, seniors or children, people with certain medical conditions (such as liver or kidney problems, heart disease, diabetes, seizures) or people who take other medications are more at risk of developing a wider range of side effects. View complete list of side effects
4. Bottom Line
Codeine is an effective pain-reliever; however, it is addictive, may cause constipation, and its pain-relieving effects vary markedly between individuals. should only be used for pain relief when other simpler analgesics, such as acetaminophen or ibuprofen, are not appropriate.
May be taken with or without food. Do not take more than you have been prescribed. Codeine should be used short-term only. Long-term use may lead to addiction and dependence. may need to be discontinued slowly depending on the duration of use. Talk to your doctor about a tapering schedule. Never share your it with anyone. Do not keep your leftover medicine. Ask your pharmacy when the next take-back program is.
May cause sedation and affect your ability to drive or operate machinery. Do not drive or perform other hazardous tasks if it affects you in this way.
Use short-term (three days or less) only. Not recommended for long-term use.
Tell your doctor if you think you have become addicted to it or the usual dosage does not appear to be working.
6. Response and effectiveness
The analgesic effect of reaches a peak in about two hours and the effects last for between four to six hours.
About 70-80% of a dose of it is metabolized by the liver into a number of metabolites, some active and some inactive. One of these active metabolites is morphine. About 5-10% of it is metabolized into morphine by the hepatic enzyme, CYP2D6. Experts believe some of the analgesic properties of it are due to it being converted into morphine. Note that up to 10% of Caucasians, 6% of Mexican-Americans, and 5% of African-Americans are poor metabolizers at CYP2D6 and are unlikely to metabolize codeine into morphine. 30% of Ethiopians, 20% of Saudis, 10% of Portuguese and Greeks, and 4% of North Americans are ultra-rapid metabolizers at CYP 2D6 and may experience excessive side effects, such as extreme sleepiness, confusion, and shallow breathing, even with normal dosages of it
Medicines that interact with may either decrease its effect, affect how long it works for, increase side effects, or have less of an effect when taken with it . An interaction between two medications does not always mean that you must stop taking one of the medications; however, sometimes it does. Speak to your doctor about how drug interactions should be managed.
Common medications that may interact :
antibiotics, such as erythromycin
antidepressants, such as tricyclic antidepressants (eg, amitriptyline), monoamine oxidase inhibitors (eg, isocarboxazid, phenelzine, and tranylcypromine), or SSRIs (eg, fluoxetine, sertraline)
antifungal agents, such as itraconazole and ketoconazole
anticonvulsants, such as carbamazepine, lamotrigine, phenytoin, phenobarbital, or primidone
antimigraine agents such as sumatriptan
antipsychotics (such as butyrophenones, phenothiazines, or thioxanthenes) and atypical antipsychotics (eg, olanzapine, quetiapine, ziprasidone)
any medication that may cause drowsiness, such as amphetamines, azelastine, benzodiazepines (eg, diazepam, lorazepam), first-generation antihistamines (such as doxylamine or promethazine), metoclopramide, or opioids (such as hydrocodone, morphine)
HIV medications such as darunavir or ritonavir
muscle relaxants, such as cyclobenzaprine
other medications that are CYP2D6 or CYP3A4 inhibitors or inducers
