Olmesartan/hydrochlorothiazide is a fixed-dose combination medication designed for the treatment of hypertension in adults who require more than one agent to achieve adequate blood pressure control. Olmesartan, an angiotensin II receptor blocker (ARB), works by relaxing blood vessels and reducing the effects of hormones that cause vasoconstriction. Hydrochlorothiazide complements this action by promoting diuresis, which decreases fluid volume and further lowers blood pressure. Together, these mechanisms help reduce cardiovascular risk and protect organs such as the heart, brain, and kidneys from long-term damage caused by uncontrolled hypertension.
This medication is typically prescribed when single-drug therapy is insufficient. Patients should maintain proper hydration and follow dietary recommendations to minimize side effects. Monitoring kidney function and electrolytes is essential, as the diuretic component can alter fluid and mineral balance. Olmesartan/hydrochlorothiazide is not suitable for pregnant women or individuals with severe kidney disease. When used appropriately, it plays a key role in comprehensive blood pressure management and reducing the risk of serious complications like stroke and heart attack.
Common side effects include dizziness, headache, fatigue, and increased urination. Some patients may experience nausea, muscle cramps, or mild electrolyte changes. Serious but rare risks include kidney problems, severe low blood pressure, and allergic reactions. Patients should seek medical attention for symptoms such as fainting, irregular heartbeat, or swelling of the face and throat. Regular blood tests and blood pressure checks help ensure safe and effective use. Avoid excessive alcohol and inform your doctor about all medications you take to prevent harmful interactions.

This is the best thing to happen since…
Thank you Telrx for creating this company. It's so hard to get doctor's appointments! For common ailments, we usually know what we need before we go to the doctor's office...this saves so much time, money and headache! Thank You!!

This is the first time using an online prescription pharmacy
I was hesitant, but everything about the experience was very positive. From requesting the medication to receiving it was quick and easy. From time of order to receipt was only 2 days. Very happy and will not hesitate to use in the future.

Do I need to have a prescription?
Not to get started. Complete a short health questionnaire and a licensed provider will review your request. Already have one? You can transfer it to TelyRx directly.
How do I transfer my existing prescription to the TelyRx platform?
Make sure you have created an account with TelyRx if you haven't already done so. Select the “I have a prescription” option when adding your request to your cart. If we don’t have the exact medication (dosage, quantity, formulation) matching your prescription, we recommend that you request a prescription through our platform to reduce any potential delay or denial. Provide your current pharmacy’s name and phone number, as well as your prescription number. Our customer service team will reach out for more information as needed.
If your prescription details differ from the order you submitted, such as if the dosage differs, your order will be cancelled and you will not be charged.
If we do not have your exact match in dosage, quantity, or formulation, we recommend selecting the “I need a prescription” option to avoid potential fulfillment delays. Your request will be reviewed by an independent, licensed provider.
