1. What is Fludetén and what is it used for

Fludetén is an association of paracetamol and codeine. Paracetamol is an active analgesic and antipyretic principle (relieves pain and reduces fever) whose analgesic activity is enhanced by codeine. Codeine belongs to a group of medications called opioid analgesics that act by relieving pain.

This medication can be used in adolescents over 15 years of age for the short-term treatment of moderate pain that is not relieved by other analgesics such as paracetamol or ibuprofen alone.

2. What you need to know before taking Fludetén

Do not take Fludetén

• if you are allergic to paracetamol, codeine, or any of the other components of this medication (listed in section 6)
• if you have bronchial asthma
• if you have respiratory depression
• if you have been diagnosed with increased intracranial pressure
• to relieve pain in children and adolescents (0-18 years of age) after tonsil or adenoid removal who suffer from obstructive sleep apnea syndrome
• if you know you metabolize codeine very quickly into morphine
• if you are breastfeeding.

Warnings and Precautions

• It is essential to use the smallest dose that relieves the pain and not exceed the recommended doses in Section 3 - "How to take Fludetén" for this, avoid taking other medications that contain paracetamol or codeine (used, for example, to treat colds, pain, and fever).

Consult your doctor or pharmacist before starting to take Fludetén:

• If you have any heart or lung disease and in patients with anemia (decrease in hemoglobin levels in the blood, due to or not due to a decrease in red blood cells), or with low levels of a blood enzyme called glucose-6-phosphate dehydrogenase, you should consult your doctor before taking the medication.
• If you have liver (including Gilbert's syndrome) or kidney problems or suffer from chronic malnutrition or are dehydrated, you may require a reduction in the dose of the medication.
• If you have any disease that affects your ability to breathe, have intracranial injuries, for example, due to a head injury, are asthmatic, or have a history of asthma and/or are sensitive to acetylsalicylic acid.
• If you have any thyroid, prostate, or urethral stricture (both of which cause difficulties in urination), adrenal insufficiency (Addison's disease), or intestinal or gallbladder conditions.
• If you are an elderly person or feel weak.
• If you have chronic constipation, the use of this medication can worsen the symptoms.
• Codeine is transformed into morphine in the liver by an enzyme. Morphine is the substance that produces pain relief. Some people have a variation of this enzyme that can affect people in different ways. In some people, morphine is not produced or is produced in very low quantities, and it will not provide sufficient pain relief. Other people are more likely to suffer from severe 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 medication and seek medical help immediately: slow or shallow breathing, confusion, drowsiness, constricted pupils, nausea or vomiting, constipation, loss of appetite.
• If you consume alcoholic beverages, it can cause paracetamol to damage the liver.
• Prolonged or frequent use of analgesics to treat headaches can worsen symptoms, which should not be treated with higher doses of the medication.
• With repeated administration of this medication, physical dependence and tolerance may appear. Administration should be gradually suspended after prolonged treatments. If you need to take this medication for a prolonged period, the treatment should be periodically reevaluated by your doctor.
• If the pain persists for more than 3 days (2 days for throat pain), worsens, or other symptoms appear, you should interrupt treatment and consult your doctor.
• If you have severe diseases, such as severe renal failure or sepsis (when bacteria and their toxins circulate in the blood, causing damage to organs), or if you suffer from malnutrition, chronic alcoholism, or are also taking flucloxacillin (an antibiotic). A severe disease called metabolic acidosis (an anomaly in blood and fluids) has been reported in patients in these situations when paracetamol is used at regular doses for a prolonged period or when paracetamol is taken with flucloxacillin. The symptoms of metabolic acidosis may include: severe breathing difficulties with deep and rapid breathing, drowsiness, feeling unwell (nausea) and vomiting.

Interference with Analytical Tests

If you are going to undergo any analytical test (including blood tests, urine tests, skin tests that use allergens, etc.), inform your doctor that you are taking Fludetén, as it may alter the results of these tests.

Taking Fludetén with Other Medications

Inform your doctor or pharmacist if you are taking, have recently taken, or may need to take any other medication.

In particular, if you are taking medications that contain any of the following active ingredients, it may be necessary to modify the dose or interrupt treatment of any of them.

Paracetamolmay interact with the following medications:

• Oral anticoagulants (acenocoumarol, warfarin)
• Medications used for the relief of stomach, intestine, and bladder spasms or cramps (anticholinergics)
• Antiepileptics (lamotrigine, phenytoin, and other hydantoins, phenobarbital, methylphenobarbital, primidone, carbamazepine)
• Antituberculars (isoniazid, rifampicin)
• Barbiturates (used as sleep inducers, sedatives, and anticonvulsants)
• Colestyramine (used to decrease cholesterol levels in blood)
• Propranolol (adrenergic blocker) used in the treatment of high blood pressure (hypertension) and heart rhythm disorders (cardiac arrhythmias)
• Medications used for the treatment of gout (probenecid and sulfinpyrazone)
• Metoclopramide and domperidone (used to prevent nausea and vomiting)
• Zidovudine (used in the treatment of patients infected with the human immunodeficiency virus, the cause of AIDS).
• Flucloxacillin (antibiotic), due to a serious risk of alteration of blood and fluids (called metabolic acidosis) that should be treated urgently (see section 2).

On the other hand, codeinemay interact with the following medications:

• Narcotic analgesics (used for pain treatment) such as nalbuphine, buprenorphine, pentazocine
• Antidepressants (used to treat depression)
• Sedatives (used to treat depression, anxiety)
• Sedating antihistamines H1 (used to treat allergies)
• Anxiolytics (used to treat anxiety)
• Neuroleptic hypnotics (used to treat insomnia)
• Clonidine and related medications (used to treat hypertension and migraine)
• Thalidomide (used to treat some types of cancer)
• Benzodiazepines
• Medications used for the relief of stomach, intestine, and bladder spasms or cramps (anticholinergics).

Do not use other analgesics (medications that reduce pain) without consulting your doctor.

Taking Fludetén with Food, Drinks, and Alcohol

The use of paracetamol in patients who habitually consume alcohol (three or more alcoholic beverages per day) can damage the liver. Additionally, alcohol can potentiate the depressive effect of codeine. Therefore, you should not consume alcohol during treatment with this medication.

Children and Adolescents

Use in children and adolescents after surgery

Codeine should not be used for pain relief in children and adolescents after tonsil or adenoid removal due to obstructive sleep apnea syndrome.

Use in children with respiratory problems

The use of codeine is not recommended in children with respiratory problems, as the symptoms of morphine toxicity can be worse in these children.

Pregnancy, Breastfeeding, and Fertility

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before taking this medication.

Do not take this medication if you are breastfeeding. Codeine and morphine pass into breast milk.

Driving and Using Machines

Fludetén contains codeine, which can cause drowsiness, altering mental and/or physical ability. If you notice these effects, avoid driving vehicles or using machines.

Fludetén Contains Sodium

This medication contains 491.4 mg of sodium (main component of table salt/cooking salt) per tablet. This is equivalent to 25% of the maximum daily sodium intake recommended for an adult.

Consult your doctor or pharmacist if you need to take 1 or more tablets per day for a prolonged period, especially if you have been recommended a low-salt diet (sodium).

Use in Athletes:This medication contains codeine. As a consequence of its metabolism, some compounds are produced that can result in a positive test in doping controls.

If You Forget to Take Fludetén

Do not take a double dose to make up for forgotten doses.

In case you have forgotten a dose, take another as soon as possible and continue with the new schedule, maintaining the minimum interval of 6 hours. However, if the time of the next dose is very close, skip the forgotten dose and take the next dose at the usual time.

If You Stop Taking Fludetén

Your doctor will indicate the duration of treatment with Fludetén and when and how you should stop it.

Do not suspend treatment beforehand, as you will not achieve the expected effect.
