losartan potassium + hydrochlorothiazide
Lorista HD is a combination of an angiotensin II receptor antagonist (losartan) and a diuretic (hydrochlorothiazide). Angiotensin II is a substance produced in the body that, by binding to receptors in blood vessel walls, causes them to narrow. This results in increased blood pressure. Losartan prevents angiotensin II from binding to these receptors, causing blood vessels to widen and, as a result, lowering blood pressure. Hydrochlorothiazide works by increasing the flow of water and salt through the kidneys. This also helps to lower blood pressure.
Lorista HD is indicated for the treatment of primary hypertension (high blood pressure).
Before starting treatment with Lorista HD, discuss it with your doctor or pharmacist:
Your doctor may monitor your kidney function, blood pressure, and electrolyte levels (e.g. potassium) in your blood at regular intervals.
See also the information under the heading "When not to take Lorista HD".
If you experience stomach pain, nausea, vomiting, or diarrhea after taking Lorista HD, discuss it with your doctor. Your doctor will decide on further treatment. Do not stop taking Lorista HD on your own.
Inform your doctor about pregnancy, suspected pregnancy, or planned pregnancy. The use of Lorista HD is not recommended in early pregnancy and should not be taken after the third month of pregnancy, as it may harm the fetus if taken during this period of pregnancy (see "Pregnancy and breastfeeding").
Tell your doctor or pharmacist about all medicines you are taking, have recently taken, or might take.
Tell your doctor about any potassium supplements, salt substitutes containing potassium, potassium-sparing medicines, or other medicines that may increase potassium levels in your blood (e.g. trimethoprim-containing medicines), as their concurrent use with Lorista HD is not recommended.
Diuretics, such as hydrochlorothiazide in Lorista HD, may interact with other medicines.
Do not take lithium-containing products and Lorista HD at the same time without close medical supervision.
Special precautions (e.g. blood tests) may be necessary if you are taking other diuretics, certain laxatives, gout treatments, or medicines for heart rhythm or diabetes control (oral antidiabetics or insulin). It is also important for your doctor to know if you are taking other blood pressure-lowering medicines, steroids, anticancer medicines, painkillers, antifungal medicines, or medicines for arthritis, cholesterol-lowering resins such as cholestyramine, muscle relaxants, sedatives, opioid analgesics such as morphine, "pressor amines" such as adrenaline, or other medicines from the same group, as well as oral antidiabetics or insulin.
Your doctor may need to adjust the dose and/or take other precautions:
You should also inform your doctor about taking Lorista HD before scheduled administration of iodine-containing contrast agents.
Lorista HD can be taken with or without food.
It is recommended that you do not drink alcohol while taking Lorista HD, as alcohol and Lorista HD tablets may enhance each other's effects.
Excessive salt intake in your diet may reduce the effect of Lorista HD.
You should avoid drinking grapefruit juice while taking Lorista HD tablets.
If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
Pregnancy
Inform your doctor about pregnancy, suspected pregnancy, or planned pregnancy. Your doctor will usually advise you to stop taking Lorista HD before planned pregnancy or as soon as possible after finding out you are pregnant, and will recommend an alternative medicine instead of Lorista HD. Lorista HD is not recommended during early pregnancy and should not be taken after the third month of pregnancy, as it may seriously harm the fetus if taken during this period of pregnancy.
Breastfeeding
Inform your doctor about breastfeeding or intention to breastfeed. Lorista HD is not recommended during breastfeeding, and your doctor may prescribe a different treatment if you want to breastfeed, especially if your baby is a newborn or premature.
There is no experience with the use of Lorista HD in children and adolescents, so it should not be used in this patient group.
Lorista HD is as effective and well-tolerated in elderly patients as in younger patients. Most elderly patients require the same dose as younger patients.
When starting treatment with Lorista HD, you should not perform activities that require special attention (e.g. driving a car or operating hazardous machinery) until you know how you tolerate this medicine.
If you have been diagnosed with intolerance to some sugars, you should consult your doctor before taking this medicine.
Take this medicine always as directed by your doctor or pharmacist. If you are unsure, ask your doctor or pharmacist. Your doctor will decide on the appropriate dose of Lorista HD, depending on your condition and other medicines you are taking. It is important to continue taking Lorista HD for as long as your doctor has prescribed it to maintain consistent blood pressure control.
Hypertension
Usually, for most patients with high blood pressure, one tablet of Lorista H 50 mg losartan and 12.5 mg hydrochlorothiazide per day is sufficient to control blood pressure for 24 hours. Your doctor may increase the dose to two tablets of Lorista H 50 mg losartan and 12.5 mg hydrochlorothiazide once daily or change to one tablet of Lorista HD 100 mg losartan and 25 mg hydrochlorothiazide (higher dose) once daily. The maximum daily dose is two tablets of Lorista H 50 mg losartan and 12.5 mg hydrochlorothiazide or one tablet of Lorista HD 100 mg losartan and 25 mg hydrochlorothiazide.
In case of overdose, contact your doctor immediately to take appropriate action. Overdose may cause low blood pressure, rapid heartbeat, slow heart rate, changes in blood composition, and dehydration.
Try to take Lorista HD every day as directed by your doctor. If you miss a dose, do not take a double dose to make up for the missed dose; continue taking the medicine as before.
If you have any further questions about taking this medicine, ask your doctor or pharmacist.
