Lopressor HCT (Oral)

Metoprolol and hydrochlorothiazide combination is used to treat high blood pressure (hypertension). High blood pressure increases the workload of the heart and arteries. If it lasts for a long time, the heart and arteries may not work properly. This can harm the blood vessels in the brain, heart, and kidneys, leading to a stroke, heart failure, or kidney failure. High blood pressure may also raise the risk of heart attacks. Controlling blood pressure can help reduce the chances of these problems.

Metoprolol is a beta-blocker. It works by changing how some nerve impulses affect certain parts of the body, such as the heart. This causes the heart to beat slower and lowers blood pressure. When blood pressure decreases, more blood and oxygen reach the heart.

Hydrochlorothiazide is a thiazide diuretic (water pill). It lowers the amount of water in the body by increasing urine flow, which helps reduce blood pressure.

This medicine is available only with your doctor's prescription.

It is very important for your doctor to check your progress at regular visits to ensure this medicine is working properly and to look for unwanted effects. Blood and urine tests may be needed to check for unwanted effects.

This medicine may worsen heart failure symptoms in some patients. Contact your doctor immediately if you experience chest pain or discomfort, dilated neck veins, extreme fatigue, irregular breathing, an uneven heartbeat, swelling of the face, fingers, feet, or lower legs, or weight gain.

This medicine may cause changes in blood sugar levels. It may also mask symptoms of low blood sugar, such as a rapid pulse rate. Speak with your doctor if you notice a change in your usual symptoms or in your blood or urine sugar test results. Call your doctor right away if you experience anxiety, blurred vision, chills, cold sweats, coma, confusion, cool, pale skin, depression, dizziness, fast heartbeat, headache, increased hunger, nausea, nervousness, nightmares, seizures, shakiness, slurred speech, or unusual tiredness or weakness.

This medicine may increase your risk of skin cancer (for example, non-melanoma skin cancer). Avoid sun exposure. Use sunscreen when outdoors. Avoid sunlamps and tanning beds. Discuss any concerns about this risk with your doctor.

Make sure any doctor or dentist treating you is aware that you are using this medicine. Do not stop taking this medicine before surgery without your doctor's approval.

This medicine may cause some people to feel less alert than usual. If this happens, do not drive, operate machinery, or do anything else that could be dangerous if you are not alert while taking this medicine.

Do not stop or interrupt taking this medicine without first checking with your doctor. Your doctor may want you to gradually reduce the dose before stopping completely. Some conditions may worsen if the medicine is stopped suddenly, which can be dangerous.

Contact your doctor right away if you start to have a dry mouth, increased thirst, muscle cramps, nausea or vomiting, unusual tiredness or weakness, severe drowsiness or dizziness, seizures, decreased urine output, or a fast heartbeat while using this medicine. These may be signs of dehydration or mineral imbalance.

Check with your doctor immediately if you experience blurred vision, difficulty reading, eye pain, or any other changes in vision during or after treatment. This could indicate a serious eye problem. Your doctor will likely want you to see an ophthalmologist (eye doctor).

Some men using this medicine may experience erectile dysfunction. Contact your doctor right away if you notice decreased interest in sexual intercourse, inability to have or maintain an erection, or loss of sexual ability, drive, or performance. If you have questions about this, speak with your doctor.

Alcohol, narcotic pain relievers, or sleeping pills may make you feel more lightheaded, dizzy, or faint when combined with this medicine. Inform your doctor if you are drinking alcohol or using any pain relievers or sleeping pills.

Do not take other medicines unless you have discussed them with your doctor. This includes prescription and nonprescription (over-the-counter) medications for appetite control, asthma, colds, cough, hay fever, or sinus problems, as they may raise your blood pressure.

In deciding to use a medicine, the chances of using the medicine must be weighed against the beneficial it will do. This is a decision you and your physician will make. For this drug, the following should be considered:

Allergies

Inform your physician if you have ever had any unusual or allergic reaction to this medication or any other drugs. Additionally inform your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies have not been performed on the relationship of age to the effects of metoprolol and hydrochlorothiazide combination in the pediatric population. Safety and efficacy have not been established.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of metoprolol and hydrochlorothiazide combination in the elderly. However, elderly patients are more likely to have age-related liver, kidney, or heart issues, which may require caution and an adjustment in the dose for patients receiving metoprolol and hydrochlorothiazide combination.

Breast Feeding

There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this drug while breastfeeding.
