Cyclopenthiazide

Post your experience

Cyclopenthiazide belongs to the group of medicines known as thiazide diuretics.
Thiazide diuretics are often referred to as water tablets.
Cyclopenthiazide is available alone or in combination with other drugs.
Cyclopenthiazide removes excess water from the body by increasing how often you urinate (pass water).
People with high blood pressure often do not feel unwell, but left untreated, high blood pressure can harm the heart and damage blood vessels resulting in a heart attack, stroke, heart failure or kidney failure.

Cyclopenthiazide works in the kidney. It removes excess water from the body by increasing how often you urinate (pass water).

Before taking cyclopenthiazide

Before taking cyclopenthiazide make sure your doctor or pharmacist knows:

If you are pregnant, trying for a baby or breast-feeding.
If you suffer from liver or kidney problems.
If you suffer from Addison's disease or diabetes .
If you suffer from gout (pain and stiffness in the joints) or systemic lupus erythematosus (SLE).

If you suffer from hypercalcaemia (high blood calcium) or hyperuricaemia (high blood uric acid).

How to take cyclopenthiazide

Cyclopenthiazide will make you urinate (pass water) more often, so your doctor or pharmacist will usually advise you to take your dose in the morning so as not to disturb your sleep. If you take more than one dose per day, take the last dose by 2pm in the afternoon.
If you miss a dose of cyclopenthiazide take it as soon as you remember. However, if it is after 2pm in the afternoon skip the missed dose and continue taking it at the usual times. Never take two doses at the same time.

Getting the most from your treatment

Many patients with high blood pressure do not feel unwell, but left untreated, high blood pressure can harm the heart and damage blood vessels resulting in a heart attack, stroke, heart failure or kidney failure. Therefore, take cyclopenthiazide exactly as your doctor has directed and do not stop taking it without speaking to your doctor first.
If you have diabetes cyclopenthiazide may affect your blood sugar levels. Test your urine or blood regularly. Speak to your doctor or pharmacist if you notice any changes.
Your doctor may want you to have regular blood tests if you are on certain other medication.
