1. What is Codeisan and what is it used for
Codeine phosphate is a water-soluble salt of codeine. Codeine calms cough (antitussive), so it is used in the symptomatic treatment of unproductive cough (cough without secretions).
Codeine can also be used in children over 12 years of age for the short-term treatment of moderate pain that is not relieved by other painkillers such as paracetamol or ibuprofen alone.
This medication contains codeine. Codeine belongs to a group of medications called opioid analgesics that work by relieving pain. It can be used alone or in combination with other painkillers such as paracetamol.
2. What you need to know before you take Codeisan
Do not take Codeisan
- if you are allergic to codeine or any of the other ingredients of this medicine
(listed in section 6),
- if you have respiratory problems (chronic obstructive pulmonary disease, acute asthma attacks or respiratory depression),
if you have paralytic ileus (intestinal obstruction) or are at risk of having it,
- if you have diarrhea associated with pseudomembranous colitis or diarrhea caused by poisoning,
- to relieve pain in children or adolescents (0-18 years of age) after tonsillectomy or adenoidectomy due to obstructive sleep apnea syndrome
- if you are under 12 years of age.
- if you know you metabolize codeine very quickly into morphine.
- if you are breastfeeding.
Warnings and precautions
Consult your doctor or pharmacist before starting to take this medicine.
- If you have heart, lung, liver, gallbladder, or kidney problems, as well as in cases of prostate disorders (prostatic hypertrophy), urethral stricture (urethral stenosis), adrenal insufficiency (Addison's disease), intestinal obstructive or inflammatory disorders, chronic ulcerative colitis, acute pancreatitis, hypothyroidism, multiple sclerosis.
- Codeine is converted into morphine in the liver by an enzyme. Morphine is the substance that produces the effect of codeine and relieves pain and cough symptoms. Some people have a variant of this enzyme that can affect them differently. In some people, morphine is not produced or is produced in very low amounts, and it will not provide sufficient pain or cough relief. Other people are more likely to suffer from serious adverse reactions because they produce a very high amount of morphine. If you experience any of the following side effects, you should stop taking this medicine and seek medical help immediately: slow or shallow breathing, confusion, drowsiness, constricted pupils, discomfort or feeling of discomfort, constipation, loss of appetite.
- Elderly or debilitated people are usually more sensitive to the effects and adverse reactions of this medicine, especially respiratory depression.
- In the event of a severe head injury (cranial trauma) and increased pressure inside the brain (intracranial), codeine may increase the pressure of the cerebrospinal fluid, potentially increasing the respiratory depressant effect (slow or insufficient breathing).
- Like other opioids, codeine may inhibit intestinal movement, worsening constipation in patients with chronic constipation.
- Abuse and dependence:Prolonged and excessive administration of codeine can cause dependence and/or tolerance, especially in people with a tendency to abuse and addiction. Codeine should be used with caution in patients with a history of drug abuse or dependence. After prolonged treatments, the administration should be gradually discontinued as indicated by your doctor.
- This medicine should not be taken for more than three days. If the pain does not improve after three days, ask your doctor for advice.
Children and adolescents
- Use in children and adolescents after surgery
Codeine should not be used to relieve pain in children and adolescents after tonsillectomy or adenoidectomy due to obstructive sleep apnea syndrome.
- Use in children with respiratory problems
Codeine is not recommended for use in children with respiratory problems, as the symptoms of morphine toxicity can be worse in these children.
- Adolescents over 12 years of age
Codeine is not recommended for use in adolescents with respiratory problems for the treatment of cough.
- Codeine is not recommended for use in children who may have respiratory problems, such as neuromuscular disorders, severe respiratory or heart disease, lung or upper airway infections, multiple trauma, or those who have undergone extensive surgical procedures.
- Children under 12 years of age are at a higher risk of suffering from adverse reactions after taking codeine; these reactions can be very serious in children who break down codeine into a large amount or quickly (extensive or ultra-rapid metabolizers).
Using Codeisan with other medicines
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.
- Central nervous system depressants (CNS): The administration of codeine with other CNS depressant drugs (such as narcotic analgesics, anxiolytics, antipsychotics, neuromuscular blockers, antidepressants, antihistamines H1, neuroleptics, adrenergic blockers) may cause additive CNS depression, so the dose should be reduced.
- The concomitant use of codeine and sedative medications such as benzodiazepines or related medications increases the risk of drowsiness, difficulty breathing (respiratory depression), coma, and can be potentially fatal. Due to this, concomitant use should only be considered when other treatment options are not possible.
However, if your doctor prescribes codeine with sedative medications, your doctor should limit the dose and duration of concomitant treatment.
Tell your doctor about all sedative medications you are taking and closely follow your doctor's dose recommendation. It may be helpful to inform friends or family members who are aware of the signs and symptoms indicated above. Contact your doctor when you experience such symptoms.
- The use of opioid agonists such as buprenorphine may increase the effects of codeine. The use of opioid antagonists such as naltrexone may delay the effects of codeine.
- The simultaneous administration with anticholinergics may cause paralytic ileus and/or urinary retention.
- The use of antidepressants such as monoamine oxidase inhibitors (MAOIs) or tricyclic antidepressants may potentiate the effects of codeine or antidepressants.
- The administration of antihistamines such as hydroxyzine may produce increased analgesia and sedation.
Some phenothiazines (used for nervous, mental, or emotional disorders) increase the analgesia induced by codeine, while others decrease it.
Using Codeisan with alcohol
Consuming alcohol may increase drowsiness by potentiating the depressant effect of codeine on the central nervous system.
Pregnancy, breastfeeding, and fertility
If you are pregnant, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine.
Pregnancy
Codeine is not recommended during pregnancy. Its use may cause physical dependence in the fetus, leading to withdrawal symptoms in the newborn.
Breastfeeding
Do not take codeine if you are breastfeeding. Codeine and morphine pass into breast milk.
Driving and using machines
Codeine may cause drowsiness, altering the mental and/or physical ability required for the performance of potentially hazardous activities, such as driving vehicles or operating machines. Avoid driving vehicles or using machines during treatment.
Use in athletes
This medication contains a component that can establish a positive opioid control test result.
Codeisan contains sodium
This medicine contains less than 1 mmol of sodium (23 mg) per tablet; this is, essentially "sodium-free".
