1. What Kostarox is and what it is used for

What is Kostarox?

• Kostarox contains the active substance etoricoxib. Kostarox is a medicine belonging to 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 relieve pain and reduce swelling (inflammation) in joints and muscles in people aged 16 years and older with osteoarthritis, rheumatoid arthritis, ankylosing spondylitis, and gouty arthritis.
• Kostarox is also used for the short-term treatment of moderate pain following dental surgery in people aged 16 years and older.

What is osteoarthritis?
Osteoarthritis is a joint disease. It develops as a result of gradual breakdown of the cartilage lining the ends of bones. This leads to swelling (inflammation), pain, tenderness, stiffness, and impaired function.
What is rheumatoid arthritis?
Rheumatoid arthritis is a long-lasting inflammatory joint disease. It causes pain, stiffness, swelling, and reduced mobility of the affected joints. It may also cause inflammation in other parts of the body.
What is ankylosing spondylitis?
Ankylosing spondylitis is an inflammatory disease affecting the spine and large joints.
What is gout?
Gout is a disease characterized by sudden, recurring attacks of very painful inflammation and redness of joints. It is caused by deposition of crystalline deposits in the joint.

2. Important information before using Kostarox

When not to use Kostarox

• if the patient is allergic to etoricoxib or to any of the other ingredients of this medicine (listed in section 6);
• if the patient is allergic to nonsteroidal 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 or may be pregnant or is breastfeeding (see section "Pregnancy, breastfeeding and fertility");
• in individuals under 16 years of age;
• if the patient has inflammatory bowel disease, such as Crohn's disease, ulcerative colitis or colitis;
• if the patient has uncontrolled high blood pressure (if in doubt whether the patient's blood pressure is adequately controlled, consult a doctor);
• if the patient has been diagnosed with heart disorders, including heart failure (moderate or severe type), angina pectoris (chest pain), or has had a myocardial infarction or coronary artery bypass surgery (bypass grafting);
• if the patient has peripheral arterial disease (poor circulation in legs or feet due to narrowed or blocked arteries);
• if the patient has ever had a stroke (including "mini-stroke", transient ischaemic attack [TIA]). Etoricoxib may slightly increase the risk of heart attack and stroke; therefore, it should not be used in patients who have previously had heart problems or stroke.

If in doubt whether any of the above points apply to the patient,
do not take this medicine until consulting a doctor.
Warnings and precautions
Before using Kostarox, discuss with your doctor or pharmacist if:

• the patient previously had gastrointestinal bleeding or gastric ulcer;
• the patient is dehydrated, e.g. due to prolonged recurrent vomiting or diarrhoea;
• if the patient has fluid retention causing oedema;
• the patient previously had heart failure or other heart disease;
• the patient previously had high blood pressure. Kostarox may increase blood pressure in some individuals, especially when used at high doses; therefore, the doctor will periodically monitor the patient's blood pressure.
• the patient previously had liver or kidney disease;
• 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 levels, or smokes. These patients have an increased risk of heart disease;
• the patient plans to become pregnant;
• the patient is elderly (over 65 years of age).

If in doubt whether any of the above conditions apply to the patient, before
using Kostarox, consult a doctor to determine whether this medicine
can be taken.
The effect of Kostarox is similar in elderly and younger adult patients.
In patients over 65 years of age, the doctor will closely monitor treatment.
Dose adjustment in patients over 65 years of age is not necessary.
Children and adolescents
This medicine must not be used in children and adolescents under 16 years of age.
Kostarox and other medicines
Inform your doctor or pharmacist about all medicines currently or recently taken, as well as any medicines the patient intends to take.
If the patient is taking any of the following medicines, the doctor may decide that monitoring is necessary to ensure that treatment with Kostarox proceeds safely:

• anticoagulants (blood thinners), such as warfarin;
• rifampicin (an antibiotic);
• methotrexate (a medicine used to suppress the immune system, often used in the treatment of rheumatoid arthritis);
• cyclosporine or tacrolimus (medicines used to suppress immune system function, e.g. after organ transplantation);
• lithium (a medicine used to treat certain types of depression);
• medicines used to treat high blood pressure and heart failure, known as ACE inhibitors and angiotensin receptor blockers (e.g. enalapril and ramipril, losartan and valsartan);
• diuretics;
• digoxin (a medicine used to treat heart failure and heart rhythm disorders);
• minoxidil (a medicine used to treat high blood pressure);
• oral tablets or oral solution of salbutamol (a medicine used to treat asthma);
• oral contraceptives (combination with Kostarox may increase the risk of adverse effects);
• hormone replacement therapy (combination with Kostarox may increase the risk of adverse effects);
• acetylsalicylic acid (the risk of gastric ulcers is higher when Kostarox is used concomitantly with acetylsalicylic acid);
• acetylsalicylic acid used for prevention of heart attack or stroke: Kostarox may be taken together with low-dose acetylsalicylic acid. If the patient is currently taking low-dose acetylsalicylic acid to prevent heart attack or stroke, do not stop taking it without consulting a doctor.
• acetylsalicylic acid and other nonsteroidal anti-inflammatory drugs (NSAIDs): during treatment with Kostarox, high doses of acetylsalicylic acid or other anti-inflammatory medicines must not be taken.
