Package Leaflet: Information for the PatientKarvezide 300mg/25mg film-coated tablets
Irbesartan/Hydrochlorothiazide
Read all of this leaflet carefully before you start taking this medicine because it contains important information for you.
Contents of the pack
Karvezide is a combination of two active substances, irbesartan and hydrochlorothiazide.
Irbesartan belongs to a group of medicines known as angiotensin-II receptor antagonists.
Angiotensin-II is a substance produced in the body that binds to receptors in blood vessels, causing them to narrow. This results in an increase in blood pressure. Irbesartan blocks the binding of angiotensin-II to these receptors, relaxing blood vessels and lowering blood pressure.
Hydrochlorothiazide belongs to a group of medicines called thiazide diuretics, which increase the amount of urine removed from the body, reducing blood pressure.
The two active substances in Karvezide work together to achieve a greater reduction in blood pressure than either substance alone.
Karvezide is used to treat high blood pressure, when treatment with irbesartan or hydrochlorothiazide alone has not provided adequate control of blood pressure.
Do not take Karvezide
Warnings and precautions
Consult your doctor before starting to take Karvezide and in any of the following cases:
Your doctor may monitor your kidney function, blood pressure, and blood electrolyte levels (e.g., potassium) at regular intervals.
Consult your doctor if you experience abdominal pain, nausea, vomiting, or diarrhea after taking Karvezide. Your doctor will decide whether to continue treatment. Do not stop taking Karvezide on your own.
See also the information under the heading “Do not take Karvezide”.
If you are pregnant, think you may be pregnant, or are planning to become pregnant, inform your doctor. Karvezide is not recommended during the first trimester of pregnancy and must not be used after the third month of pregnancy, as it may cause serious harm to your baby (see section “Pregnancy”).
You must also inform your doctor:
Hydrochlorothiazide contained in this medicine may cause positive results in doping tests.
Children and adolescents
Karvezide should not be given to children and adolescents (under 18 years of age).
Using Karvezide with other medicines
Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicines.
Diuretics, such as hydrochlorothiazide contained in Karvezide, may have an effect on other medicines. You should not take preparations containing lithium with Karvezide without your doctor's supervision.
Your doctor may need to adjust your dose and/or take other precautions:
If you are taking an angiotensin-converting enzyme inhibitor (ACE inhibitor) or aliskiren (see also the information under the headings “Do not take Karvezide” and “Warnings and precautions”).
You may need to have blood tests if you take:
It is also important to inform your doctor if you are taking other medicines to lower your blood pressure, steroids, medicines to treat cancer, painkillers, medicines for arthritis, or cholestyramine or colestipol resins to lower blood cholesterol levels.
Taking Karvezide with food, drinks, and alcohol
Karvezide can be taken with or without food.
Due to the hydrochlorothiazide contained in Karvezide, if you drink alcohol while being treated with this medicine, you may experience increased dizziness when standing up, especially when getting up from a sitting or lying position.
Pregnancy, breastfeeding, and fertility
Pregnancy
You should inform your doctor if you are pregnant, think you may be pregnant, or are planning to become pregnant. Your doctor will normally advise you to stop taking Karvezide before you become pregnant or as soon as you know you are pregnant and will advise you to take another medicine to treat your high blood pressure. Karvezide is not recommended during the first trimester of pregnancy and must not be used after the third month of pregnancy, as it may cause serious harm to your baby.
Breastfeeding
Inform your doctor if you are about to start or are already breastfeeding, as Karvezide is not recommended for use during breastfeeding. Your doctor may decide to prescribe a different treatment that is more suitable if you want to breastfeed, especially for newborns or premature babies.
Driving and using machines
Karvezide is unlikely to affect your ability to drive or use machines. However, during treatment for high blood pressure, dizziness or fatigue may occasionally occur. If you experience these symptoms, talk to your doctor before driving or using machines.
Karvezide contains lactose. If your doctor has told you that you have an intolerance to some sugars, contact your doctor before taking this medicine.
Karvezide contains sodium. This medicine contains less than 1 mmol of sodium (23 mg) per tablet, which is essentially “sodium-free”.
Always take this medicine exactly as your doctor has told you. If you are not sure, check with your doctor or pharmacist.
Dose
The recommended dose of Karvezide is one tablet per day. In general, your doctor will prescribe Karvezide when previous treatments you have received have not sufficiently reduced your blood pressure. Your doctor will indicate how to switch from previous treatments to Karvezide.
Method of administration
Karvezide is taken orally. The tablets should be swallowed with a sufficient amount of liquid (e.g., a glass of water). You can take Karvezide with or without food. Try to take your daily dose at the same time each day. It is important that you continue to take Karvezide until your doctor tells you to stop.
The maximum blood pressure-lowering effect should be achieved within 6-8 weeks after starting treatment.
If you take more Karvezide than you should
If you accidentally take too many tablets, contact your doctor immediately.
Children should not take Karvezide
Karvezide should not be given to children under 18 years of age. If a child swallows some tablets, contact your doctor immediately.
If you forget to take Karvezide
If you accidentally miss a dose, simply take your normal dose when it is due. Do not take a double dose to make up for forgotten doses.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
