telmisartan - hydrochlorothiazide
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.

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Allergic reaction: Some people who are allergic to sulfonamide medications also experience allergic reactions to hydrochlorothiazide. Before you take this medication, tell your doctor about any previous reactions you have had to medications, especially to sulfonamide antibiotics or diabetes medications. Contact your doctor at once if you experience signs of an allergic reaction, such as skin rash, itching, difficulty breathing, or swelling of the face and throat.
Angioedema: This medication may cause a serious allergic reaction called angioedema, which may be fatal if not treated promptly. If you have difficulty breathing or notice hives or swelling of the face, lips, tongue, or throat, stop taking this medication and get emergency medical help immediately. Other angiotensin II receptor antagonists should not be taken in the future. People who have had angioedema caused by other substances may be at increased risk of angioedema while taking this medication.
Cholesterol: Cholesterol and triglyceride levels may increase when taking hydrochlorothiazide. 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: Telmisartan – hydrochlorothiazide can cause changes to kidney function that may result in decreased kidney function, kidney failure, or possibly death. Certain people have experienced changes in kidney function (e.g., people with narrowed blood vessels in their kidneys, or those with severe congestive heart failure). The use of diuretics (water pills), nonsteroidal anti-inflammatory drugs (NSAIDs), or aliskiren may further increase risk of kidney problems for people already at risk for this problem. If you have reduced kidney function, renal artery stenosis (narrowing of blood vessels in the kidneys), or congestive heart failure, 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. If you have reduced kidney function, you may require lower doses of this medication.
Liver function: Liver disease or reduced liver function may cause this medication to build up in the body, causing side effects. If you have reduced liver function or liver 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 is not recommended for people with severe liver impairment.
This medication may also cause a decrease in liver function. If you experience symptoms of liver problems such as fatigue, feeling unwell, loss of appetite, nausea, yellowing of the skin or whites of the eyes, dark urine, pale stools, abdominal pain or swelling, and itchy skin, contact your doctor immediately.
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) or the medication aliskiren, 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, people with low blood pressure or who are 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 extreme drop in blood pressure because of reduced fluid in your blood vessels. Vomiting or diarrhea may also lead to a drop in blood pressure. Consult your doctor if you feel your blood pressure is too low.
Lupus: There have been reports of a worsening or activation of lupus in people taking hydrochlorothiazide. If you have lupus or a history of lupus, 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.
Sensitivity to sunlight: This medication may increase the sensitivity of the skin to sunlight, increasing the risk of sunburn. Avoid exposure to sunlight for long periods of time, particularly between the hours of 10 am and 2 pm, while you are taking this medication. Wear a broad-spectrum sunscreen with an SPF of 30 or higher. If you notice any unusual skin rash or peeling, contact your doctor immediately.
Skin cancer: Recent studies of hydrochlorothiazide have suggested that long-term use of hydrochlorothiazide may be associated with an increased risk of developing non-melanoma skin cancer. Regularly check your skin for new moles or lesions or changes to any existing ones and let your doctor know if you have any concerns.
Vision changes: Hydrochlorothiazide occasionally causes vision changes, including increased eye pressure and myopia (nearsightedness). If you experience any eye symptoms, such as pain or change in vision, contact your doctor as soon as possible.
Pregnancy: Telmisartan can cause injury or death to the developing fetus if taken by a woman who is pregnant. This medication should not be taken by pregnant women. If you become pregnant while taking telmisartan – hydrochlorothiazide, consult your doctor immediately as the medication should be stopped as soon as possible.
Breast-feeding: It is not known if telmisartan passes into breast milk. Hydrochlorothiazide does pass into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.
Children: The safety and effectiveness of using this medication have not been established for children and is not recommended.
Seniors: Seniors may be more sensitive to the side effects of this medication.
