1. What Corixil is and what it is used for

Corixil film-coated tablets contain two active substances called valsartan and hydrochlorothiazide.
Both of these substances help control high blood pressure (hypertension).

• Valsartan belongs to a class of medicines known as “angiotensin II receptor antagonists”, which help control high blood pressure. Angiotensin II is a substance in the body that causes blood vessels to narrow, thereby increasing blood pressure. Valsartan works by blocking the effect of angiotensin II. As a result, blood vessels relax and blood pressure decreases.
• Hydrochlorothiazide belongs to a group of medicines called thiazide diuretics. Hydrochlorothiazide increases the amount of urine produced and, in this way, helps reduce blood pressure.

Corixil is used to treat high blood pressure when it is not sufficiently controlled by a single medicine.
High blood pressure increases the workload on the heart and arteries. If left untreated, it can damage the blood vessels in the brain, heart, and kidneys, leading to stroke, heart failure, or kidney failure. High blood pressure also increases the risk of heart attack. Lowering blood pressure to normal levels reduces the risk of developing these conditions.

2. What you should know before taking Corixil

Do not take Corixil:

• if you are allergic (hypersensitive) to valsartan, hydrochlorothiazide, sulfonamide derivatives (chemically related substances to hydrochlorothiazide), or to any of the other ingredients of this medicine (listed in section 6)
• if you are more than 3 months pregnant (it is better to avoid taking Corixil even in the early stages of pregnancy – see section Pregnancy)
• if you have severe liver problems, destruction of the small bile ducts within the liver (biliary cirrhosis) leading to bile accumulation in the liver (cholestasis)
• if you have severe kidney problems
• if you are unable to urinate (anuria)
• if you are undergoing treatment with an artificial kidney
• if your blood potassium or sodium levels are lower than normal, or if your blood calcium levels are higher than normal despite treatment
• if you have gout
• if you have diabetes or impaired kidney function and are being treated with a blood pressure-lowering medicine containing aliskiren.

If any of the above apply to you, consult your doctor and do not take Corixil.
Warnings and precautions
Consult your doctor

• if you are taking potassium-sparing medicines, potassium supplements, potassium-containing salt substitutes, or other medicines that increase potassium levels in the blood, such as heparin. Your doctor may need to regularly monitor your blood potassium levels
• if your blood potassium levels are low
• if you have diarrhoea or severe vomiting
• if you are taking high doses of medicines that increase fluid elimination (diuretics)
• if you have serious heart problems
• if you suffer from heart failure or have had a heart attack. Follow your doctor’s instructions carefully regarding the starting dose of treatment. Your doctor will also monitor your kidney function
• if you have narrowing of the renal artery
• if you have recently received a kidney transplant
• if you have hyperaldosteronism, a condition in which the adrenal glands produce too much aldosterone hormone. If this applies to you, use of Corixil is not recommended
• if you have liver or kidney diseases
• if you have previously experienced swelling of the tongue and face due to an allergic reaction called angioedema when taking other medicines (including ACE inhibitors), inform your doctor. If these symptoms occur while taking Corixil, stop taking Corixil immediately and never take it again. See section 4, “Possible side effects”
• if you have fever, skin rash, and joint pain, which may be signs of systemic lupus erythematosus (SLE, an autoimmune disease)
• if you have diabetes, gout, or elevated cholesterol or triglyceride levels in the blood
• if you have had allergic reactions when using other blood pressure-lowering medicines belonging to the same class (angiotensin II receptor antagonists) or if you suffer from allergies or asthma
• if you experience a decrease in vision or eye pain. These may be symptoms of fluid accumulation in the vascular layer of the eye (choroidal effusion) or increased intraocular pressure and may occur within hours or weeks after taking Corixil. If untreated, this may lead to permanent vision loss. If you previously had an allergy to penicillins or sulfonamides, you may have a higher risk of developing this condition
• if you are taking any of the following medicines used to treat high blood pressure:
• an “ACE inhibitor” (e.g., enalapril, lisinopril, ramipril), particularly if you have kidney problems related to diabetes
• aliskiren
• if you have previously had skin cancer or are developing unexpected skin lesions during treatment. Treatment with hydrochlorothiazide, especially long-term use with high doses, may increase the risk of certain types of non-melanoma skin cancer and lip cancer. Protect your skin from sun exposure and UV radiation while taking Corixil.
• if you have previously experienced respiratory or lung problems (including inflammation or fluid in the lungs) after taking hydrochlorothiazide. If shortness of breath or severe breathing difficulty occurs after taking Corixil, consult a doctor immediately.

Your doctor may regularly monitor your kidney function, blood pressure, and blood electrolyte levels (e.g., potassium).
See also the information under “Do not take Corixil”.
Corixil may cause increased skin sensitivity to sunlight.
Use of Corixil is not recommended in children and adolescents (under 18 years of age).
You must inform your doctor if you think you may be pregnant (or if there is a possibility of becoming pregnant). Corixil is not recommended during early pregnancy and must not be taken if you are more than 3 months pregnant, as it may cause serious harm to the unborn child if taken during this period (see section Pregnancy).
Other medicines and Corixil
Inform your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.
The effect of treatment may be affected if Corixil is taken with certain other medicines. It may be necessary to adjust the dose, take additional precautions, or in some cases, stop taking one of the medicines. This particularly applies to the following medicines:

• lithium, a medicine used in the treatment of certain psychiatric disorders
• medicines or substances that may increase blood potassium levels. These include potassium supplements or potassium-containing salt substitutes, potassium-sparing medicines, and heparin
• medicines that may decrease blood potassium levels, such as diuretics (medicines that increase fluid elimination), corticosteroids, laxatives, carbenoxolone, amphotericin, or penicillin G
• certain antibiotics (rifampicin group), a drug used to prevent transplant rejection (cyclosporine), or an antiretroviral drug used to treat HIV/AIDS infections (ritonavir). These medicines may increase the effect of Corixil.
• medicines that may cause torsades de pointes (irregular heartbeat), such as antiarrhythmics (medicines used to treat heart problems) and certain antipsychotics
• medicines that may reduce blood sodium levels, such as antidepressants, antipsychotics, antiepileptics
• medicines for the treatment of gout, such as allopurinol, probenecid, sulfinpyrazone
• therapeutic supplements of vitamin D and calcium
• medicines used to treat diabetes (oral agents such as metformin or insulin)
• other medicines that lower blood pressure, including methyldopa, ACE inhibitors (such as enalapril, lisinopril, etc.), or aliskiren (see also information under: “Do not take Corixil” and “Warnings and precautions”)
• medicines that may increase blood pressure, such as noradrenaline or adrenaline
• digoxin or other digitalis glycosides (medicines used to treat heart problems)
• medicines that may increase blood sugar levels, such as diazoxide or beta-blockers
• cytotoxic medicines (used in cancer treatment), such as methotrexate or cyclophosphamide
• painkillers such as non-steroidal anti-inflammatory drugs (NSAIDs), including selective cyclooxygenase-2 (COX-2) inhibitors and acetylsalicylic acid > 3 g
• muscle relaxants, such as tubocurarine
• anticholinergic medicines (used to treat various disorders such as gastrointestinal cramps, bladder spasms, asthma, motion sickness, muscle spasms, Parkinson’s disease, and to facilitate anaesthesia)
• amantadine (a medicine used to treat Parkinson’s disease and also to treat or prevent certain viral diseases)
• cholestyramine and colestipol (medicines mainly used in the treatment of high blood lipid levels)
• cyclosporine, a medicine used in organ transplantation to prevent organ rejection
• alcohol, sedatives, and anaesthetics (medicines with narcotic or painkilling effects used, for example, during surgical procedures)
• iodinated contrast agents (used in radiological examinations)

Corixil with food, drinks and alcohol
Avoid consuming alcohol unless you have discussed it with your doctor. Alcohol may further lower blood pressure and/or increase the risk of dizziness or fainting.
Pregnancy and breastfeeding

• You must inform your doctor if you think you may be pregnant (or if there is a possibility of becoming pregnant). Your doctor will usually advise you to stop taking Corixil before becoming pregnant or as soon as you find out you are pregnant, and will recommend an alternative medicine instead of Corixil. Corixil is not recommended during early pregnancy and must not be taken if you are more than 3 months pregnant, as it may cause serious harm to the unborn child if taken after the third month of pregnancy.
• Inform your doctor if you are breastfeeding or planning to breastfeed. Corixil is not recommended for women who are breastfeeding, and your doctor may choose an alternative treatment if you wish to breastfeed, especially if the baby is a newborn or was born prematurely.

Driving and using machines
Before driving a vehicle, operating machinery, or performing other activities requiring concentration, you should be aware of how you react to Corixil. Like many other medicines used to treat high blood pressure, Corixil may rarely cause dizziness and affect your ability to concentrate.
For athletes: using the medicine without therapeutic need constitutes doping and may result in a positive anti-doping test.

3. How to take Corixil

Take this medicine exactly as your doctor has instructed you. This will help you achieve the best results and reduce the risk of side effects. If you have any doubts, consult your doctor or pharmacist.
People with high blood pressure often do not notice any signs of this condition and many feel as well as usual. For this reason, it is very important that you keep regular appointments with your doctor, even when you feel perfectly well.
Your doctor will tell you exactly how many Corixil tablets you should take. Depending on your response to treatment, your doctor may recommend a higher or lower dose.

• The recommended dose of Corixil is one tablet daily.
• Do not change the dose and do not stop taking the tablets without first consulting your doctor.
• This medicine should be taken every day at the same time, usually in the morning.
• You may take Corixil with or without food.
• Swallow the tablet with a glass of water.

If you take more Corixil than you should
If you experience severe dizziness and/or fainting, lie down and contact your doctor immediately.
If you have accidentally taken too many tablets, contact your doctor, pharmacist or hospital.
If you forget to take Corixil
If you forget to take a dose, take it as soon as you remember. However, if it is almost time for your next dose, skip the missed dose.
Do not take a double dose to make up for a forgotten dose.
If you stop taking Corixil
Stopping treatment with Corixil may cause your high blood pressure to worsen. Do not discontinue use of this medicine unless instructed by your doctor.
If you have any questions about how to use this medicine, consult your doctor or pharmacist.
