Drug Description


Tribenzor is a prescribed medication used to treat hypertension (high blood pressure) either on its own or in combination with other antihypertensive drugs. Reducing blood pressure helps mitigate the likelihood of life-threatening cardiovascular events, predominantly strokes and myocardial infarctions. 

Tribenzor comprises three medications: olmesartan, an angiotensin receptor blocker (ARB), amlodipine, a calcium channel blocker, and hydrochlorothiazide, a diuretic.  

Olmesartan and amlodipine function by promoting blood vessel relaxation, facilitating improved blood flow. Conversely, hydrochlorothiazide works by enhancing salt and water excretion through increased urine production. 

Uses and Dosage 

Before taking Tribenzor and with every prescription refill, carefully review its medication guide and patient information leaflet. For any concerns, consult your healthcare provider or pharmacist. 

The dosage of Tribenzor is determined based on the patient’s medical condition and response to the treatment. 

Typically, Tribenzor is taken once daily as prescribed by the doctor, without regard to food intake. 

To ensure optimal results, follow the prescribed regimen for this medication diligently, taking it at consistent times every day. 

Keep taking Tribenzor even if you are feeling well, as many individuals with high blood pressure may not experience symptoms.  

Inform your doctor if there is no improvement in your condition or if it deteriorates (blood pressure readings remain elevated or escalate).

Notify your pharmacist about the products you are using as some may contain ingredients that can elevate blood pressure. Seek advice on their proper usage, especially when it comes to cough-and-cold remedies, dietary supplements, or NSAIDs such as ibuprofen and naproxen. 

Prior to consuming potassium supplements or salt substitutes containing potassium, consult with your doctor or pharmacist due to the potential impact of Tribenzor on potassium levels. 

Patients with diabetes should monitor their blood sugar levels regularly while taking Tribenzor and report the findings to their doctor. Adjustments to diabetes medication, exercise regimen, or diet may be necessary as advised by the doctor. 

Lab tests may be affected by Tribenzor, resulting in potential inaccuracies in the test outcomes. Communicate your usage of this medication to lab personnel and all medical professionals involved. 

Hydrochlorothiazide heightens the likelihood of developing skin cancer.  Avoiding direct sunlight and tanning beds is recommended. When outdoors, don protective attire and apply sunscreen with an SPF of 30 or above. Regular skin check-ups may be recommended by your physician. 

Excessive sweating, diarrhea, or vomiting can heighten the likelihood of feeling dizzy or dehydrated. Inform your physician if you experience prolonged bouts of diarrhea or vomiting. To avoid dehydration while taking Tribenzor, ensure an ample intake of fluids unless otherwise instructed by your doctor. 

Do not utilize Tribenzor if you are pregnant, as olmesartan can pose a risk of harm or fatality to the unborn child when taken during the second or third trimester. Promptly inform your healthcare provider if you become pregnant while on this medication. 

The transfer of olmesartan into breast milk is uncertain, whereas hydrochlorothiazide and amlodipine do pass into breast milk. Prior to breastfeeding, consult with your healthcare provider.
