Warnings and Precautions
Anti-inflammatory/analgesic medicines like ibuprofen may be associated with a small increased risk of heart attack or stroke, especially when used in high doses. Do not exceed the recommended dose or treatment duration. Do not take more than 3 sachets of granules (1200 mg of ibuprofen) per day, to avoid the possible appearance of circulatory or heart problems.
Tell your doctor
It is important to use the smallest dose that relieves-controls the pain and not to take this medicine for longer than necessary to control your symptoms.
Avoid concomitant administration with other NSAIDs, including COX-2 inhibitors.
Precautions in Elderly Patients
Elderly patients have a higher frequency of adverse reactions to NSAIDs (non-steroidal anti-inflammatory drugs), especially gastrointestinal bleeding and perforation, which can be fatal.
Cardiovascular precautions
Anti-inflammatory/analgesic medicines like ibuprofen may be associated with a small increased risk of heart attack or stroke, especially when used in high doses. Do not exceed the recommended dose or treatment duration.
You should discuss your treatment with your doctor or pharmacist before taking Difenadol Rapid if:
Similarly, these types of medicines can cause fluid retention, especially in patients with heart failure and/or high blood pressure (hypertension).
Respiratory Disorders
Ibuprofen should be used with caution when administered to patients who have or have a history of bronchial asthma, chronic rhinitis, or allergic diseases, as ibuprofen has been reported to cause bronchospasm, urticaria, or angioedema in these patients.
Severe Adverse Skin Reactions (SASR)
Severe skin reactions have been reported, including exfoliative dermatitis, erythema multiforme, Stevens-Johnson syndrome, toxic epidermal necrolysis, drug reaction with eosinophilia and systemic symptoms (DRESS), and acute generalized exanthematous pustulosis (AGEP), in association with ibuprofen treatment. Discontinue treatment with Difenadol Rapid and seek medical attention immediately if you notice any of the symptoms related to these severe skin reactions described in section 4.
Children and Adolescents
There is a risk of kidney failure in dehydrated children and adolescents.
This medicine is not recommended for use in children and adolescents weighing less than 40 kg or under 12 years old, as the dose of ibuprofen it contains is not suitable for the recommended dosage in this group of patients.
Precautions during Pregnancy and in Women of Childbearing Age
Because the administration of ibuprofen-type medicines has been associated with an increased risk of congenital anomalies/abortions, their administration is not recommended during the first and second trimesters of pregnancy unless strictly necessary and advised by your doctor.
If you need treatment during this period or while trying to become pregnant, you should use the lowest dose for the shortest possible time.
If you take it for a few days from the 20th week of gestation onwards, Difenadol Rapid may cause kidney problems in your baby, which can lead to low levels of amniotic fluid surrounding the baby (oligohydramnios) or narrowing of a blood vessel (ductus arteriosus) in the baby's heart. If you need treatment for a few more days, your doctor may recommend additional monitoring.
In the third trimester, the administration of ibuprofen is contraindicated.
For women of childbearing age, it should be noted that ibuprofen-type medicines have been associated with a decrease in fertility.
Interference with Laboratory Tests
If you are going to undergo any diagnostic test (including blood tests, urine tests, skin tests using allergens, etc.), inform your doctor that you are taking this medicine, as it may alter the results.
Other Medicines and Difenadol Rapid
Tell your doctor or pharmacist if you are using, have recently used, or may need to use any other medicine.
Difenadol Rapid may affect or be affected by other medicines. For example:
The following medicines may interfere and should not be taken with Difenadol Rapid without consulting your doctor:
Other medicines may also affect or be affected by treatment with Difenadol Rapid. Therefore, you should always consult your doctor or pharmacist before using Difenadol Rapid with other medicines.
Taking Difenadol Rapid with Food, Drinks, and Alcohol
Take this medicine with meals or with milk.
Do not administer ibuprofen with alcohol to avoid damaging the stomach. Alcohol consumption during treatment may increase the risk of gastrointestinal adverse reactions.
Pregnancy, Breastfeeding, and Fertility
If you are pregnant or breastfeeding, think you may be pregnant, or are planning to become pregnant, consult your doctor or pharmacist before using this medicine.
Difenadol Rapid should not be taken during pregnancy, especially during the third trimester (see section precautions during pregnancy and in women of childbearing age). It may cause kidney and heart problems in your baby. It may affect your and your baby's tendency to bleed and make labor longer than expected.
Minimal amounts of ibuprofen and its degradation products are excreted in breast milk. As no adverse effects are known in the infant, it is not usually necessary to interrupt breastfeeding during short-term use at recommended doses.
Therefore, if you become pregnant or are breastfeeding, consult your doctor.
Driving and Using Machines
If you experience dizziness, vertigo, vision changes, or other symptoms while taking this medicine, you should not drive or use hazardous machinery. If you only take one dose of ibuprofen or for a short period, it is not necessary to take special precautions.
Difenadol Rapid contains Aspartame, Sucrose, and Sodium

The recommended dose is:
No more than 3 sachets (1200 mg of ibuprofen) should be taken in 24 hours.
The administration of this medicine is subject to the appearance of pain or fever. As these disappear, the medication should be suspended.
You should consult a doctor if it worsens or does not improve, if the fever persists for more than 3 days or the pain for more than 3 days in adolescents or 5 days in adults.
Use in children
The use of this medicine is not recommended in children and adolescents with less than 40 kg of weight or under 12 years, as the dose of ibuprofen it contains is not suitable for the recommended posology in this group of patients.

In case of overdose or accidental ingestion, consult immediately with a doctor or pharmacist or call the Toxicology Information Service (telephone: 91 562 04 20), indicating the medicine and the amount ingested or go to the nearest hospital to find out about the risk and ask for advice on the measures to be taken.
Symptoms of overdose may include nausea, stomach pain, vomiting (which may contain bloody sputum), gastrointestinal bleeding (see also section 4 below), diarrhea, dizziness, spasms, hypotension, or depression of the nervous system (reduction of consciousness) headache, ringing in the ears, confusion, and involuntary eye movement.
Nervousness, drowsiness, disorientation, or coma may also occur. Occasionally, patients develop seizures.
At high doses, symptoms of drowsiness, chest pain, palpitations, loss of consciousness, seizures (mainly in children), weakness, and dizziness, blood in the urine, low potassium levels in the blood, chills, and breathing problems have been reported.
In cases of significant overdose, renal failure and liver damage may occur.
Also, the prothrombin time/INR may be prolonged, probably due to interference with the action of circulating coagulation factors. Acute renal failure and liver damage may appear. It is possible that asthma may worsen in asthmatic patients. There is also a possibility that low blood pressure and reduced breathing may occur.
In case of ingestion of significant amounts, activated charcoal should be administered. Gastric lavage will be considered if large amounts have been ingested and within 60 minutes after ingestion.
If you forget to take Difenadol rapid
Do not take a double dose to make up for forgotten doses.
If you forget to take your corresponding dose, take it as soon as you remember. However, if the time of the next dose is very close, skip the forgotten dose and take the next dose at its usual time.
If you have any other doubts about the use of this product, ask your doctor or pharmacist.
