HOW SHOULD THIS MEDICINE BE USED?
Lopressor HCT® (metoprolol tartrate and hydrochlorothiazide) Tablets come in tablet form, which can be taken by mouth. The specific dosage of Lopressor HCT that your doctor prescribes for you will depend on your medical condition and your response to treatment.
Take this medicine exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label. Do not suddenly stop taking this medicine without consulting your doctor because your condition may worsen if you suddenly stop taking Lopressor HCT.
If you miss a dose, take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up for the missed dose.
Take the medicine with a meal or right after you eat.
Your doctor may occasionally change your dose to make sure you get the best results.
Lopressor HCT is not indicated for the initial therapy of hypertension. Hydrochlorothiazide is usually given at a dosage of 12.5 to 50 mg per day. The usual dosage of Lopressor is 100 to 450 mg daily in one or two doses. If the combination represents the dose titrated for your needs, then therapy with the fixed combination may be more convenient than with the separate components.
Tell your doctor if your condition does not improve or worsens.
Do not stop using Lopressor HCT suddenly, or you could have serious or life-threatening heart problems. Talk to your doctor about how to avoid withdrawal symptoms when stopping the medicine.
