promethazine with codeine syrup is addictive (habit-forming) and potentially abusable. should only be used short-term at the lowest effective dose and only when other nonopioid analgesics are not effective. Tolerance can also develop to codeine’s analgesic effect (this means that the same dose does not provide as much pain relief as before). Legitimate supplies of products containing codeine may be sought out by drug seekers.
Abrupt discontinuation of the bottle in a person who has become physically dependent on it may lead to a withdrawal syndrome and symptoms such as restlessness, pupil dilation, watery eyes and a runny nose, sweating, muscle aches, insomnia, irritability and gastrointestinal complaints.
Rarely, serious, life-threatening, breathing problems may occur attributable to the component. The risk is greater with higher dosages of it, in people with pre-existing respiratory disease, in seniors or the frail, or in those taking other medications that cause respiratory depression (such as benzodiazepines). Not for use in children under the age of 18.
promethazine with codeine syrup may interact with several drugs, including those that affect hepatic enzymes CYP 3A4 or CYP 2D6, and those that also cause respiratory depression (such as other opioids, benzodiazepines, and alcohol).
Interaction or overdosage may also cause serotonin syndrome. Symptoms include mental status changes such as agitation, hallucinations, coma, or delirium; a fast heart rate; dizziness; flushing; muscle tremor or rigidity; and stomach symptoms (including nausea, vomiting, and diarrhea).
Long-term use of cough medicine also affects the endocrine system, which may cause symptoms such as sexual dysfunction, an absence of periods, or infertility.
Codeine is an opiate and prodrug of morphine used to treat pain, coughing, and diarrhea.It is found naturally in the sap of the opium poppy, Papaver somniferum. It is typically used to treat mild to moderate degrees of pain.
Drowsiness or dizziness which may impair reaction skills and affect a person’s ability to drive or operate machinery. Avoid alcohol.
also slows down the motility of the gastrointestinal tract. This can lead to symptoms such as nausea, vomiting, constipation, and abdominal pain. Laxatives may be required.
may also affect blood pressure, manifesting as dizziness when standing; and stimulate histamine release, which may cause symptoms such as flushing, itchiness, sweating, or red eyes.
Babies born to mothers who are physically dependent on it will also be physically dependent.
Marked differences may exist in the analgesic effect provided by due to genetic variations in the CYP 2D6 liver enzyme responsible for metabolizing into morphine. Consider alternative analgesics if promethazine with codeine syrup is not having the desired pain-relieving effect.
Note that this list is not all-inclusive and includes only common medications that may interact with tylenol with codeine #3. You should refer to the prescribing information for codeine for a complete list of interactions.
Do not double up on other medications containing promethazine with codeine syrup (several cold and flu remedies also contain this ).
Avoid alcohol while taking . Alcohol can contribute to the sedative effects of and also increase the risk of respiratory depression.
may make you feel dizzy when getting up from a lying down or sitting position to standing. Always get up slowly, but talk with your doctor if this dizziness results in a fall.
Codeine may cause constipation which can be relieved with laxatives. Drink 6 to 8 full glasses of water daily to prevent this effect. Talk to your doctor if you experience any troublesome side effects of before using a laxative..

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:

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 codeine 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 codeine 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 codeine 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 codeine 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 codeine 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 with codeine include:
