1. What is Diclac 100 and what is it used for

Diclac 100 contains diclofenac sodium, which belongs to the group of non-steroidal anti-inflammatory drugs (NSAIDs), with anti-rheumatic, anti-inflammatory, analgesic, and antipyretic properties. The mechanism of action of Diclac 100 involves the inhibition of prostaglandin biosynthesis, which plays a key role in the pathogenesis of inflammation, pain, and fever.
Diclac 100 is used to treat:

• inflammatory or degenerative forms of rheumatic disease: rheumatoid arthritis, juvenile rheumatoid arthritis (Still's disease), ankylosing spondylitis, osteoarthritis, psoriatic arthritis, spinal arthritis, pain syndromes associated with spinal changes, extra-articular rheumatism;
• acute attacks of gout;
• pain caused by post-traumatic and post-operative inflammatory conditions and edema, e.g., after dental or orthopedic procedures;
• painful and/or inflammatory conditions in gynecology, e.g., primary dysmenorrhea or adnexitis;
• migraine attacks;
• supportive treatment in severe, painful infections of the ear, nose, or throat (i.e., pharyngitis and tonsillitis, otitis). According to general therapeutic principles, in the case of the above-mentioned diseases, causal treatment should be applied first. Fever, as the only symptom, is not an indication for use.

Control tests during the use of Diclac 100

In patients with diagnosed heart disease or significant risk factors for heart disease, the attending physician 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, the doctor will order regular blood tests to monitor liver function (aminotransferase activity), kidney function (creatinine levels), and blood cell count (white and red blood cells and platelets). Based on the test results, the doctor will decide whether to discontinue treatment with Diclac 100 or change the dose of the medicine.

2. Important information before using Diclac 100

When not to use Diclac 100

• if the patient is hypersensitive to diclofenac or any of the other ingredients of this medicine (listed in section 6),
• if the patient has ever had an allergic reaction after using anti-inflammatory or analgesic drugs (e.g., acetylsalicylic acid, diclofenac, or ibuprofen). Reactions may include asthma, rhinitis, skin rash, urticaria, facial edema, lip edema, tongue edema, pharyngeal edema, and/or limb edema (symptoms of angioedema). If the patient thinks they may be allergic, they should consult a doctor.
• if the patient has active or past stomach or duodenal ulcers, bleeding, or perforation; if the patient has experienced discomfort in the stomach area or heartburn after taking anti-inflammatory drugs,
• if the patient has proctitis or proctocolitis,
• if the patient is in the third trimester of pregnancy,
• if the patient has liver failure,
• if the patient has kidney failure,
• if the patient has heart disease and/or cerebrovascular disease (e.g., after a heart attack, stroke, transient cerebral ischemia, vascular occlusion of the heart or brain, or after a bypass grafting or angioplasty procedure),
• if the patient has circulatory disorders (peripheral vascular disease).

The patient should inform their doctor about the presence of these diseases.

Warnings and precautions

Before using Diclac 100, the patient should discuss it with their doctor if:

• the patient has diagnosed cardiovascular disease (see above) or significant risk factors such as high blood pressure, elevated lipid levels (cholesterol, triglycerides), or if the patient is a smoker, as in such cases, the dose of the medicine should not be increased above 100 mg per day if treatment lasts longer than 4 weeks;
• the patient has undergone gastrointestinal ulceration or is elderly. The use of diclofenac may cause gastrointestinal bleeding, ulceration, or perforation (with possible fatal outcome). Such effects may be particularly dangerous in the case of high doses of the medicine. If any unusual abdominal symptoms occur during the use of Diclac 100 (especially gastrointestinal bleeding), the medicine should be discontinued immediately and the patient should consult a doctor;
• the patient has ulcerative colitis or Crohn's disease, as diclofenac may exacerbate the disease;
• the patient has asthma, allergic rhinitis, nasal polyps, chronic obstructive pulmonary disease, or chronic respiratory infections, as they are more likely to experience an allergic reaction to diclofenac (exacerbation of asthma symptoms, angioedema, or urticaria). This warning also applies to patients allergic to other substances (e.g., those who experience skin reactions, itching,

or urticaria). The medicine should be used with caution (preferably under medical supervision);

• the patient has liver function disorders, as diclofenac may worsen the course of the disease. The patient should strictly follow the doctor's recommendations regarding liver function tests;
• the patient has porphyria, as diclofenac may trigger a porphyria attack.

Before using Diclac 100, the patient should inform their doctor if:

• the patient smokes,
• the patient has diabetes,
• the patient has angina pectoris, thrombosis, hypertension, elevated cholesterol levels, or elevated triglyceride levels.

The occurrence of side effects can be limited by using the medicine in the smallest effective dose and for no longer than necessary.
To minimize the risk of side effects, the smallest effective dose of Diclac 100 should be used, which alleviates pain and/or inflammation, and it should be used for the shortest possible time.
If, at any time during the use of Diclac 100, the patient experiences symptoms indicating heart or vascular problems (such as chest pain, shortness of breath, weakness, or slurred speech), they should immediately contact their doctor or hospital emergency department.
The use of diclofenac may transiently inhibit platelet aggregation.

Elderly patients may react more strongly to the effects of the medicine than other adult patients.

This medicine should always be used in accordance with the doctor's recommendations. In case of doubts, the patient should consult their doctor or pharmacist.
The recommended doses should not be exceeded. If Diclac 100 is used for more than a few weeks, regular medical check-ups should be performed to rule out unnoticed side effects.

In primary dysmenorrhea, the daily dose should be determined individually for each patient. It usually ranges from 50 mg to 150 mg. Initially, 50 mg to 100 mg should be administered, and if necessary, the dose can be increased over several menstrual cycles to a maximum dose of 200 mg per day. Treatment should be started when the first symptoms appear and, depending on their severity, continued for several days.
Treatment of migraine attacks with Diclac 100 should be started with a dose of 100 mg after the first symptoms appear. If necessary, additional suppositories can be used on the same day, up to 100 mg. If the patient requires further treatment over the next few days, the maximum daily dose should be limited to 150 mg and taken in divided doses.

Missing a dose of Diclac 100
