Do not take Fastum
Warnings and precautions
Talk to your doctor or pharmacist:
The risk of suffering an ulcer, bleeding, or perforation in the stomach or intestine is greater when high doses are used and treatments are prolonged, in patients with a history of ulcers, especially complicated ulcers with bleeding or perforation, and in the elderly. In these cases, treatment should be started with the lowest possible dose, and your doctor will consider the possibility of associating a stomach protective medication (e.g., misoprostol or other medications that block gastric acid production).
Kidney function should be monitored in patients with heart, liver, or kidney disorders, those being treated with diuretics, and especially in elderly patients, as they are more prone to kidney function disorders.
Liver enzyme levels (transaminases) should be periodically monitored in patients with liver function disorders or a history of liver problems.
Hyperkalemia (elevated potassium levels in the blood) may occur, especially in patients with diabetes, kidney failure, or those receiving concomitant treatment with hyperkalemia-promoting agents. In these circumstances, potassium levels should be monitored.
Tell your doctor:
Cardiovascular precautions
Medicines like Fastum may be associated with a small increased risk of arterial thrombotic events (e.g., heart attacks or strokes), especially when used in high doses and for prolonged treatment. Do not exceed the recommended dose or duration of treatment.
If you have heart problems, a history of strokes, or think you may be at risk of these conditions (e.g., you have high blood pressure, diabetes, high cholesterol, or are a smoker), you should discuss this treatment with your doctor or pharmacist.
Similarly, these types of medications can cause fluid retention, especially in patients with heart failure and/or high blood pressure (hypertension).
The use of NSAIDs like Fastum may increase the risk of atrial fibrillation (irregular and often rapid heart rhythm) that can lead to blood clots in the heart.
Risk of severe skin reactions
Very rarely, severe skin reactions, some of which are fatal, have been reported in association with the use of NSAIDs, including exfoliative dermatitis, Stevens-Johnson syndrome, and toxic epidermal necrolysis (see section 4). It appears that patients have a higher risk of suffering these reactions at the beginning of treatment: the onset of this adverse reaction occurs in most cases during the first month of treatment. Fastum administration should be discontinued immediately in case of the first symptoms of skin erythema (redness), lesions, or other signs of hypersensitivity.
Infections
Fastum may mask the signs of an infection, such as fever and pain. Consequently, Fastum may delay appropriate treatment of the infection, which may increase the risk of complications. This has been observed in bacterial pneumonia and bacterial skin infections related to chickenpox. If you take this medicine while having an infection and the symptoms of the infection persist or worsen, consult a doctor without delay.
Children and adolescents
The use of Fastum is not recommended in children and adolescents, as there are no available data on safety and efficacy.
Other medicines and Fastum
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.
In particular, inform your doctor or pharmacist if you are taking any of the following medicines:
Taking Fastum with food and drinks
Take the capsules with liquids. It is recommended to take with food, as this helps to reduce the risk of side effects in the stomach or intestine.
The use of NSAIDs in combination with alcohol may worsen the adverse reactions caused by the active substance, especially if they affect the gastrointestinal tract or the central nervous system.
Pregnancy, breastfeeding, and fertility
Do not take Fastum during the last three months of pregnancy or during breastfeeding.
If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
Pregnancy
Do not take Fastum during the first six months of pregnancy unless clearly necessary and as indicated by your doctor. If you need treatment during this period or while trying to become pregnant, you should take the minimum dose for the shortest possible time.
Ketoprofen may cause kidney and heart problems in your fetus. It may affect your and your baby's ability to bleed and delay or prolong labor more than expected.
From the 20th week of pregnancy, Fastum may cause kidney problems in your fetus if taken for more than a few days, which may 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 more than a few days, your doctor may recommend additional monitoring.
In the third trimester of pregnancy, the administration of ketoprofen is contraindicated.
Breastfeeding
Ketoprofen is excreted in breast milk. Therefore, the use of Fastum in women during breastfeeding is contraindicated.
Fertility
The use of Fastum may affect female fertility and is not recommended in women who are trying to conceive. In women with fertility problems or undergoing fertility investigations, the suspension of this medicine should be considered.
Driving and using machines
Fastum may slightly affect your ability to drive or use machines, as it may cause drowsiness, dizziness, convulsions, and/or vertigo, and visual disturbances as side effects of treatment. If you notice these effects, do not use machines or drive until these symptoms disappear.
Follow exactly the administration instructions of this medicine indicated by your doctor. In case of doubt, consult your doctor or pharmacist again.
If you think the action of Fastum is too strong or too weak, tell your doctor or pharmacist.
The effective dose should be used for the shortest possible time to alleviate symptoms. If you have an infection, consult a doctor without delay if the symptoms (such as fever and pain) persist or worsen (see section 2).
Your doctor will indicate the duration of your treatment with Fastum. Do not stop treatment before, as the expected results will not be achieved. Similarly, do not take this medicine for longer than indicated by your doctor.
Adults
The recommended dose is 1 capsule 3 times a day (3 capsules a day, equivalent to 150 mg of ketoprofen per day). The maximum recommended dose is 200 mg per day (4 capsules per day).
Method of administration
The capsule should be taken with liquids. It is recommended to take with food, as this helps to reduce the risk of side effects in the stomach or intestine (see section 2 "Taking Fastum with food and drinks").
Use in children and adolescents
The use of Fastum is not recommended in children and adolescents, as there are no sufficient data on safety and efficacy available.
Patient with renal impairment (kidney dysfunction) and elderly patients
Your doctor may consider reducing the initial dose. Once good individual tolerance has been verified, the dose may be adjusted.
Patient with hepatic impairment
Your doctor will prescribe the minimum effective dose.
If you take more Fastum than you should
