1. What is Kostarox and what is it used for

What is Kostarox?

• Kostarox contains the active substance etoricoxib. Kostarox is a medicine from the group of so-called "selective cyclooxygenase-2 (COX-2) inhibitors". These medicines belong to the class of non-steroidal anti-inflammatory drugs (NSAIDs).

What is Kostarox used for?

• Kostarox helps to relieve pain and reduce swelling (inflammation) of the joints and muscles in people aged 16 and over with osteoarthritis (OA), rheumatoid arthritis (RA), ankylosing spondylitis, and gout.
• Kostarox is also used for short-term treatment of moderate pain after dental surgery in people aged 16 and over.

What is osteoarthritis?

Osteoarthritis is a disease that affects the joints. It develops as a result of the gradual breakdown of cartilage lining the ends of bones. This causes swelling (inflammation), pain, tenderness, stiffness, and impaired mobility.

What is rheumatoid arthritis?

Rheumatoid arthritis is a long-lasting inflammatory disease of the joints. It causes pain, stiffness, swelling, and limited mobility of the affected joints. It also causes inflammation in other parts of the body.

What is ankylosing spondylitis?

Ankylosing spondylitis is an inflammatory disease of the spine and large joints.

What is gout?

Gout is a disease that occurs with sudden, recurring attacks of very painful inflammation and redness of the joints. It is caused by the deposition of crystalline deposits in the joint.

2. Important information before taking Kostarox

When not to take Kostarox

• if the patient is allergic to etoricoxib or any of the other ingredients of this medicine (listed in section 6);
• if the patient is allergic to non-steroidal anti-inflammatory drugs (NSAIDs), including acetylsalicylic acid and COX-2 inhibitors (see section 4 "Possible side effects");
• if the patient has active peptic ulcer or gastrointestinal bleeding;
• if the patient has severe liver disease;
• if the patient has severe kidney disease;
• if the patient is pregnant or breastfeeding or thinks she may be pregnant (see "Pregnancy, breastfeeding, and fertility");
• in people under 16 years of age;
• if the patient has inflammatory bowel disease, such as Crohn's disease, ulcerative colitis, or proctitis;
• if the patient has uncontrolled high blood pressure (if in doubt, consult a doctor).
• if the patient has been diagnosed with heart disease, including moderate or severe heart failure, angina pectoris (chest pain), or has had a heart attack, coronary artery bypass grafting (CABG);
• if the patient has peripheral arterial disease (poor circulation in the legs or feet due to narrowed or blocked arteries);
• if the patient has had any type of stroke (including "mini-stroke", transient ischemic attack [TIA]). Etoricoxib may slightly increase the risk of heart attack and stroke, so it should not be taken by people who have already had heart or stroke problems.

In case of doubt about any of the above points, the patient should not take this medicine until they have consulted a doctor.

Warnings and precautions

Before taking Kostarox, the patient should discuss it with their doctor or pharmacist if:

• the patient is dehydrated, e.g., due to prolonged, recurring vomiting or diarrhea;
• the patient has swelling due to fluid retention;
• the patient has had heart failure or other heart disease in the past;
• the patient has had high blood pressure in the past. Kostarox may increase blood pressure in some people, especially when taken in high doses, so the doctor will check the patient's blood pressure from time to time.
• the patient has had liver or kidney disease in the past;
• the patient is currently being treated for an infection. Kostarox may mask fever, which is a sign of infection;
• the patient has diabetes, high cholesterol, or smokes. These people are at increased risk of heart disease.

In case of doubt about any of the above situations, the patient should consult their doctor before taking Kostarox. The effect of Kostarox is similar in elderly and younger adult patients. In patients over 65 years old, the doctor will carefully monitor the course of treatment. Dose modification in people over 65 years old is not necessary.

• cyclosporine or tacrolimus (medicines used to suppress the immune system, e.g., after organ transplantation);
• lithium (a medicine used to treat certain types of depression);
• medicines used to control high blood pressure and heart failure, called ACE inhibitors and angiotensin receptor blockers (e.g., enalapril and ramipril, and losartan and valsartan);
