Bisoprolol and Hydrochlorothiazide (Oral)

Bisoprolol and hydrochlorothiazide combination is used in the treatment of hypertension (high blood pressure).

Overview

Bisoprolol and hydrochlorothiazide combination is sold in the US under the brand name Ziac. The medication is used to treat hypertension (high blood pressure).

In patients who suffer from hypertension, high blood pressure places greater strain on the heart and arteries. If the condition is allowed to persist untreated, the heart and arteries may cease to work efficiently, causing damage to the vessels that supply the brain, kidneys, and heart. This can cause heart failure, kidney failure, or a stroke. People who have hypertension are also at greater risk of suffering a heart attack. Treatment with bisoprolol and hydrochlorothiazide combination over the long-term controls the patient's blood pressure, greatly reducing the likelihood of the complications caused by hypertension.

Bisoprolol is a beta-blocker. Beta-blockers work by disrupting the nerve impulses to the heart and to other parts of the body, causing the heart to beat more slowly and thus lower the patient's blood pressure. As the blood pressure is reduced, the volume of blood and therefore the supply of oxygen to the heart is increased. Hydrochlorothiazide is a thiazide diuretic, or ‘water pill'. This drug stops the body from absorbing too much salt, effectively reducing the amount of water retained in the body, and also increases the production of urine. Both these effects work to alleviate fluid retention, and therefore help to lower the patient's blood pressure.

Bisoprolol and hydrochlorothiazide combination comes in tablet form and is only available on prescription from your doctor or treating specialist.

Dosage

You will be issued a Medication Guide when your medication is dispensed by your pharmacist. Make sure that you read the Guide thoroughly so that you understand how to take the medication. If you are unsure, check with your doctor or pharmacist.

Always take this medication as directed by your doctor. Do not exceed the prescribed dose or take the medicine more often that you have been told to. Do not carry on taking the drug for a longer period than you are instructed to by your doctor. Do not omit any doses; to do so could make side effects more likely and could also mean that the medication will not work as effectively.

The prescribed dose of bisoprolol and hydrochlorothiazide combination that patients are given will vary. Always keep to your doctor's instructions or the directions given on the product label. The dose outlined in this guide is based solely on the average. If the dose you have been prescribed is different, do not change it, unless your doctor tells you to. The dose and frequency of bisoprolol and hydrochlorothiazide combination that you are prescribed will depend on the strength of the tablets. The length of your course of treatment may also be adjusted by your doctor, depending on how your body responds to the drug.

Your hypertension treatment programme may also include elements of weight control, and you may also be required to change the types of foods you eat. For example, many people who are having treatment for high blood pressure are advised to eat a diet that is low in salt. Your treating physician will give you more advice on your diet and you should check with them before making any changes yourself.

You may have high blood pressure and not even realize it. For this reason, it is extremely important that you take your medication precisely as instructed by your doctor. You must also keep any check-up appointments that you have, as these are designed to enable your doctor to monitor your progress, deal with any side effects, and change your dosing regimen if necessary.

Treatment with bisoprolol and hydrochlorothiazide combination will not cure your hypertension, but it will help to control and manage it. It is possible that you will need to take the medication for the rest of your life.

For the treatment of hypertension

  • Adults: take one or two tablets daily, as one dose or in divided doses as instructed by your doctor. Your doctor may alter your dose during the course of your treatment.
  • Children: the use and dose of this medication must be determined by your doctor.

You should take these tablets whole. Do not chew, break, or crush up the tablets. You may take the tablets before or after you have eaten. If possible, try to take your medication at the same time every day to reduce the chance that you might forget a dose.

If you do miss a dose of your treatment, you should try to take the omitted dose as soon as possible. If the usual time of your next dose is almost due, skip the one you have missed and pick up your usual dosage schedule. Do NOT take a double dose to try to catch up.

Do not share your bisoprolol and hydrochlorothiazide tablets with anyone else.

If you begin to feel worse after you begin taking this medication, or if you think that your condition has failed to improve, you should consult your doctor or specialist immediately.

If this applies to you, your doctor may change the dose of one or more of your medicines. Alternatively, your doctor may put forward some ways in which you can prevent or manage the effect of any interactions.
