1. What is Olfen 100 SR and what is it used for

Olfen 100 SR contains diclofenac sodium, which belongs to a group of so-called non-steroidal anti-inflammatory drugs (NSAIDs), which have anti-rheumatic, anti-inflammatory, analgesic, and antipyretic effects. The mechanism of action of Olfen 100 SR involves the inhibition of prostaglandin biosynthesis, which plays a fundamental role in the pathogenesis of the inflammatory process, pain, and fever.

Olfen 100 SR can be used to treat pain and inflammatory conditions, including:

• Acute inflammatory joint conditions;
• Chronic inflammatory joint conditions, in particular rheumatoid arthritis (chronic joint inflammation);
• Ankylosing spondylitis (Bechterew's disease) and other inflammatory rheumatic diseases of the spine;
• Disorders resulting from degenerative joint disease and spinal inflammation;
• Rheumatic inflammatory conditions of the soft tissues;
• Pain caused by post-traumatic and post-operative inflammatory conditions and swelling, e.g., after dental or orthopedic procedures;
• Painful and/or inflammatory conditions in gynecology, e.g., primary dysmenorrhea or adnexitis.

Control tests during treatment with Olfen 100 SR

In the case of diagnosed heart disease or significant risk factors for heart disease, the doctor will periodically assess the patient's need for symptomatic treatment and their response to the medicine, especially if treatment lasts longer than 4 weeks.

During treatment, regular blood tests should be performed in the event of any liver function disorders, kidney function disorders, and blood count abnormalities.

Both liver function (transaminase levels), kidney function (creatinine levels), and blood count (white and red blood cell count and platelet count) should be monitored. The doctor will take into account the results of the blood tests when deciding to discontinue treatment with Olfen 100 SR or change the dose of the medicine.

In case of doubts about the action or reasons for prescribing Olfen 100 SR, you should consult a doctor.

2. Important information before taking Olfen 100 SR

You should carefully follow all the instructions given by your doctor or pharmacist, even if they differ from the general information contained in this leaflet.

When not to take Olfen 100 SR:

If any of the above symptoms occur, you should inform your doctor and not take Olfen 100 SR until the doctor determines that the medicine is suitable for you.

Warnings and precautions

Before starting treatment with Olfen 100 SR, you should discuss it with your doctor, pharmacist, or nurse.

You should inform your doctor if:

If you experience any unusual symptoms in the abdominal area (especially gastrointestinal bleeding), you should stop taking the medicine immediately and consult a doctor;

Before taking diclofenac, you should inform your doctor

The occurrence of side effects can be reduced by using the medicine in the smallest effective dose and for no longer than necessary. You should use the smallest dose of Olfen 100 SR that provides relief from pain and/or swelling and use it for the shortest time necessary to minimize the risk of side effects.

If at any point during treatment with Olfen 100 SR you experience symptoms indicating cardiovascular or cerebrovascular disorders, such as chest pain, shortness of breath, weakness, or slurred speech, you should immediately contact your doctor or hospital emergency department.

In very rare cases (especially at the beginning of treatment), Olfen 100 SR, like other anti-inflammatory medicines, may cause severe skin allergic reactions (e.g., exfoliative dermatitis, Stevens-Johnson syndrome with widespread rash, high fever, and joint pain, and toxic epidermal necrolysis with skin and mucous membrane lesions, high fever, and severe general condition). After the first signs of rash, mucous membrane lesions, or other symptoms of an allergic reaction, you should stop taking the medicine and consult a doctor.

In rare cases, Olfen 100 SR, like other anti-inflammatory medicines, may cause allergic reactions, including anaphylactic and pseudo-anaphylactic reactions, even if the medicine has not been used before.

Olfen 100 SR may mask the symptoms of infection (e.g., headache, high temperature), making it more difficult to diagnose and treat the infection. If you feel unwell and need to see a doctor, you should inform them that you are taking Olfen 100 SR.

If any of the above warnings apply to you, you should inform your doctor before taking Olfen 100 SR.

Other special warnings

Olfen 100 SR should not be used at the same time as other systemically acting non-steroidal anti-inflammatory drugs, including selective cyclooxygenase-2 inhibitors.

Before taking the medicine, you should inform your doctor or pharmacist about the presence of the above-mentioned diseases.

Taking medicines like Olfen 100 SR may be associated with a small increased risk of heart attack ("myocardial infarction") or stroke. The risk is more likely to occur after taking high doses and long-term treatment. You should not exceed the recommended dose or treatment duration.

If you have heart problems, have had a stroke, or suspect that you are at risk of these disorders (e.g., high blood pressure, diabetes, elevated cholesterol levels, or smoking), you should discuss your treatment with your doctor or pharmacist.

The medicine may temporarily inhibit platelet aggregation.

Before taking Olfen 100 SR, you should tell your doctor if you have recently undergone or are scheduled to undergo stomach or gastrointestinal surgery, as Olfen 100 SR may sometimes cause impaired wound healing in the intestines after surgery.
