Table of contents:

Tiazac XC is a prescription medication used to treat mild to moderate high blood pressure and chronic stable angina (chest pain). Diltiazem, the active ingredient in Tiazac belongs to a class of medications called calcium channel blockers.

Tiazac XC works by relaxing blood vessels and preventing chest pain (angina). It is available in a 24-hour tablet form and is typically taken once daily. Tiazac XC may be used in combination with beta-blockers in chronic stable angina in patients with normal ventricular function.

Use and Dosage

Tiazac XC comes in the form of a tablet, and it should be taken once a day as directed by a doctor. The tablet should be swallowed whole with a full glass of water and should not be crushed or chewed. Tiazac XC should be taken consistently, at the same time each day, and should not be abruptly discontinued without consulting a doctor. Patients should follow all instructions and dosage recommendations provided by their doctor or pharmacist.

The recommended dosage of Tiazac XC may vary depending on the medical condition being treated and the patient's individual needs. According to the search results, the usual recommended starting dose of diltiazem extended-release tablets such as Tiazac XC ranges from 180 mg daily to 240 mg daily for the treatment of high blood pressure. For the treatment of angina, the recommended dosage range is 120 mg to 180 mg once daily. The maximum antihypertensive effect is typically observed within 14 days of treatment. The maximum daily dose of Tiazac XC is 360 mg. Note that the dosage may be adjusted by a doctor based on individual patient needs. Patients should always follow the dosage instructions provided by their doctor or pharmacist.

Take Tiazac XC exactly as prescribed by your doctor. If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.
