What is the 856 green pill? A look at its ingredients
The green, round pill with the imprint "856" is a generic version of the prescription medication Hydrochlorothiazide and Triamterene. It is manufactured by Zydus Pharmaceuticals (USA) Inc. and contains two distinct diuretics. Brand names for this combination drug include Dyazide and Maxzide.
The role of active ingredients
This medication contains two active ingredients that work together to manage fluid balance in the body:
- Hydrochlorothiazide (HCTZ): As a thiazide diuretic, HCTZ works in the kidneys to remove excess water and sodium from the body. While effective, it can also cause a decrease in the body's potassium levels.
- Triamterene: This is a potassium-sparing diuretic. It works to offset the potassium loss caused by HCTZ, helping to maintain stable potassium levels within the body while still reducing fluid.
Uses and mechanism of action
This medication is primarily used to address conditions related to fluid retention and high blood pressure.
High blood pressure (hypertension)
By helping the body excrete excess sodium and water, Hydrochlorothiazide and Triamterene reduces the volume of fluid in the blood vessels. This lowers the pressure exerted on the artery walls, effectively controlling high blood pressure. Managing hypertension is crucial for preventing long-term damage to the heart, brain, and kidneys.
Edema (fluid retention)
Edema, which presents as swelling in the ankles, feet, or other parts of the body, can be caused by conditions like congestive heart failure, liver disease, or kidney disease. The combination of diuretics in this pill helps alleviate this swelling by promoting the removal of excess fluid.
Potential side effects and warnings
Patients taking the 856 pill should be aware of potential side effects, which can range from common and mild to more serious health concerns.
Common side effects
- Headache
- Dizziness
- Nausea and stomach upset
- Increased urination
Serious side effects
- Electrolyte imbalance: While triamterene is intended to help, imbalances in potassium, sodium, and magnesium can still occur. Your doctor will monitor these levels with regular blood tests.
- Kidney problems: This medication can cause or worsen existing kidney issues, and in some cases, lead to kidney stones.
- Photosensitivity: The hydrochlorothiazide component can make the skin more sensitive to sunlight, increasing the risk of severe sunburn.
- Allergic reactions: Some individuals with a sulfa drug allergy may also be allergic to hydrochlorothiazide.

| Feature | Hydrochlorothiazide (HCTZ) | Triamterene | Hydrochlorothiazide / Triamterene (856 pill) |
|---|---|---|---|
| Drug Class | Thiazide diuretic | Potassium-sparing diuretic | Combination diuretic |
| Effect on Potassium | Can cause potassium loss | Helps retain potassium | Designed to help balance potassium levels |
| Primary Use | High blood pressure, edema | Alone, can treat edema caused by certain conditions; often used in combination | High blood pressure, edema |
| Risk of High Potassium | Low risk | Higher risk, especially if used alone | Moderate risk, requires monitoring |
Important precautions and what to do if you find this pill
It is critical to consult a healthcare provider for any medication-related questions. If you have found an unlabeled pill, you should take the following steps:
- Do not take the medication unless it was specifically prescribed to you and you have confirmed it is your own. Prescription medications are tailored to an individual's specific health needs.
- Use a reliable online pill identifier tool like Drugs.com to confirm the pill's identity, color, and imprints.
- Consult with a pharmacist or doctor to confirm the medication and its intended use. Never self-diagnose or self-prescribe based solely on online information.
Special considerations before use
Before starting or continuing this medication, you should inform your doctor of any pre-existing conditions, including:
- Kidney or liver disease
- Diabetes
- Gout
- Systemic lupus erythematosus (SLE)
- History of kidney stones
- Allergies to sulfonamide drugs
Taking this medication may require regular lab work to monitor blood pressure and electrolyte levels. It's also wise to take the pill in the morning to avoid nighttime urination. For more comprehensive details on the drug, including interactions, see the MedlinePlus entry for Triamterene and Hydrochlorothiazide.
Conclusion
The green pill with 856 on it is a combination diuretic of Hydrochlorothiazide and Triamterene, prescribed for high blood pressure and edema. Its dual-action formula helps remove excess fluid and sodium while attempting to prevent potassium loss. However, it requires careful medical supervision due to potential side effects and serious risks, such as electrolyte imbalances and kidney problems. If you encounter an unidentified pill, it is essential to consult a healthcare professional to ensure safety and avoid potential harm.
