Triamterene/hydrochlorothiazide is a prescription diuretic combination used to treat high blood pressure and fluid retention. Hydrochlorothiazide helps the body remove extra salt and water, while triamterene helps reduce potassium loss. Together, they can help lower blood pressure and decrease swelling.
How to Use: Take triamterene/hydrochlorothiazide exactly as prescribed, often once daily. Many people take it in the morning to reduce nighttime urination. Your provider may monitor blood pressure, kidney function, and electrolyte levels during treatment.
Warnings & Precautions: Tell your prescribing provider if you have kidney disease, liver disease, diabetes, gout, lupus, high potassium, pregnancy, breastfeeding, or if you take ACE inhibitors, ARBs, potassium supplements, lithium, NSAIDs, or other diuretics. Contact a provider for severe dizziness, dehydration, muscle weakness, or irregular heartbeat.
Triamterene/hydrochlorothiazide side effects may include the following: dizziness, headache, increased urination, and dehydration, especially during the first few days of treatment. Some people may experience nausea, stomach upset, or muscle cramps. Because triamterene helps retain potassium, there is a risk of high potassium levels (hyperkalemia), which can cause weakness, irregular heartbeat, or tingling sensations. Conversely, hydrochlorothiazide can lead to low sodium or magnesium levels. More serious but less common side effects include kidney problems, pancreatitis, or severe skin reactions. Patients should notify their healthcare provider if they experience signs of electrolyte imbalance, such as confusion, extreme thirst, or significant changes in heartbeat.

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.

Why should I trust TelyRx?

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.
