How does this medication work? What will it do for me?
This is a combination product that contains two medications used to lower hypertension (high blood pressure): telmisartan and hydrochlorothiazide. It is used to treat high blood pressure for people who require treatment with both telmisartan and hydrochlorothiazide.
Telmisartan belongs to a class of medications called angiotensin II blockers, which help to lower blood pressure by relaxing blood vessels. Hydrochlorothiazide is a diuretic (water pill) that helps control blood pressure by getting rid of excess salt and water.

If you have increased cholesterol or triglyceride levels, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Diabetes: Hydrochlorothiazide may make it more difficult for people with diabetes to control their blood sugar levels. High blood sugar may occur, glucose tolerance may change, and diabetes may worsen. A dose adjustment of diabetes medications, including insulin, may be required. If you have diabetes, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Electrolytes: The use of hydrochlorothiazide can reduce the levels of electrolytes such as potassium, sodium, magnesium, and chloride and increase the levels of calcium. Your doctor will periodically check to see if these levels are in balance, and a potassium supplement may be recommended. Warning signs or symptoms of fluid and electrolyte imbalance include:
- dryness of mouth
- low blood pressure
- muscle pains or cramps
- muscular fatigue
- nausea and vomiting
- racing heartbeat
Hereditary fructose or galactose intolerance: Due to the sorbitol and lactose content in the medication, this medication is not suitable for people with hereditary fructose or galactose intolerance.
Gout: An acute gout attack may occur in some patients taking telmisartan - hydrochlorothiazide as a result of high levels of uric acid in the blood. Symptoms of an acute gout attack include sudden pain, swelling, and stiffness in the affected joint, often the big toe. You may also experience a fever. If this is your first attack, seek medical attention as soon as possible. If you have had gout attacks before, follow your doctor's instructions for dealing with the attack.
Kidney function: Use of this medication may affect the function of the kidneys, especially for those who already have kidney problems. If you have reduced kidney function or kidney disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. This medication should not be taken by people with severely impaired kidney function.
Liver function: Liver disease or reduced liver function may cause this medication to build up in the body, causing side effects.

This medication is not recommended for people with severe liver impairment.

Low blood pressure: Occasionally, a greater-than-expected drop in blood pressure occurs after taking this medication. It is more likely to occur if you are taking additional diuretics (water pills), have reduced salt intake, are on dialysis, or are experiencing diarrhea or vomiting. Blood pressure should be monitored more often in these situations. To reduce the risk of dizziness, those with low blood pressure or those just starting to take this medication should stand or sit up slowly when getting up from a lying down or sitting position.
If low blood pressure causes you to faint or feel lightheaded, contact your doctor.
Excessive sweating and lack of fluid intake may lead to an excessive fall in blood pressure because of reduced fluid in your blood vessels. Vomiting or diarrhea may also lead to a fall in blood pressure. Consult your doctor if you feel your blood pressure is too low.

People with lupus or a history of lupus should discuss with their doctor how this medication may affect their medical condition, how their medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
