The Critical Importance of Accurate Pill Identification
Identifying medication based solely on its physical appearance or imprint can be dangerous. The Food and Drug Administration (FDA) regulations require pills to have a unique identifier, but these imprints can be reused by different companies for different products, or combined with other letters and numbers. The "d17" imprint is a prime example of this ambiguity. Assuming a pill is one medication when it is actually another can lead to ineffective treatment, harmful drug interactions, or severe adverse effects. It is crucial to use multiple verification methods, with the pharmacist's confirmation being the gold standard. Never ingest a medication unless you are absolutely certain of its identity and dosage as prescribed for you.
Medications with the "D17" Imprint
The imprint "d17" appears on several different pills, varying in color, shape, and active ingredient. Each is prescribed for a completely different medical purpose [1.2.4]. Below is a breakdown of the most common medications associated with this imprint.
D 17 (Brown, Oval): Quinapril Hydrochloride (40 mg)
This medication, identified by a simple "D 17" on a brown, oval tablet, is Quinapril Hydrochloride 40 mg [1.2.1].
- Use: It is primarily used to treat high blood pressure (hypertension) and manage heart failure [1.2.1]. Lowering blood pressure helps prevent strokes, heart attacks, and kidney problems.
- Drug Class: Quinapril is an Angiotensin-Converting Enzyme (ACE) inhibitor [1.2.1].
- Mechanism of Action: ACE inhibitors work by relaxing blood vessels, making it easier for the heart to pump blood. They block the conversion of angiotensin I to angiotensin II, a substance that narrows blood vessels and releases hormones that can raise blood pressure.
- Key Considerations: Patients should be monitored for side effects like a dry cough, dizziness, and changes in kidney function or potassium levels. It should not be used during pregnancy due to the risk of harm to the fetus [1.7.1].
H D17 (Orange, Capsule-Shaped): HIV-1 Combination Therapy
An orange, capsule-shaped tablet debossed with 'H' on one side and 'D17' on the other is a fixed-dose combination tablet for treating Human Immunodeficiency Virus type 1 (HIV-1) [1.2.5].
- Active Ingredients: This tablet contains Dolutegravir (50 mg), Lamivudine (300 mg), and Tenofovir Disoproxil Fumarate (300 mg) [1.2.5].
- Drug Class: These are antiretroviral medications.
- Mechanism of Action: This combination of drugs attacks the HIV virus in different ways to prevent it from replicating. Dolutegravir is an integrase inhibitor, while Lamivudine and Tenofovir are nucleoside reverse transcriptase inhibitors (NRTIs). Together, they suppress the viral load in the body.
- Key Considerations: This is a powerful prescription treatment requiring strict adherence. It has a risk of serious side effects, including lactic acidosis and severe liver problems [1.2.5]. Regular monitoring by a healthcare provider is essential.
TV D17 (Blue, Oval): Deferasirox (180 mg)
A blue, oval pill with the imprint "TV D17" has been identified as Deferasirox 180 mg [1.2.3].
- Use: Deferasirox is used to treat iron overload, a condition where there is too much iron in the body, often caused by repeated blood transfusions in patients with conditions like thalassemia [1.2.3].
- Drug Class: It is a chelating agent [1.2.3].
- Mechanism of Action: It works by binding to excess iron in the bloodstream, forming a compound that is then removed from the body, primarily through feces.
- Key Considerations: Deferasirox carries a risk of serious side effects, including kidney or liver problems and gastrointestinal bleeding. Patients require regular blood tests to monitor organ function and iron levels.
M D17 (Red, Round): Desloratadine (5 mg)
A small, red, round pill with the imprint "M D17" is Desloratadine 5 mg [1.2.7].
- Use: This medication is an antihistamine used to relieve allergy symptoms such as hives (urticaria) and allergic rhinitis (hay fever) [1.2.7].
- Drug Class: It belongs to the class of second-generation antihistamines [1.2.7].
- Mechanism of Action: It works by blocking the action of histamine, a substance in the body that causes allergic symptoms like itching, sneezing, and a runny nose. As a second-generation antihistamine, it is designed to cause less drowsiness than older allergy medications.
- Key Considerations: While less sedating, some individuals may still experience drowsiness. It is available by prescription and over-the-counter in some regions.
SKF D17 / JMI D17 (White, Round): Cytomel (50 mcg)
A white, round pill with the imprint "SKF D17" or "JMI D17" is identified as Cytomel 50 mcg, which contains the active ingredient liothyronine sodium [1.2.2, 1.2.4].
- Use: It is a thyroid hormone used to treat hypothyroidism (underactive thyroid) and other thyroid-related conditions [1.2.2].
- Drug Class: It is classified as a thyroid drug [1.2.2].
- Mechanism of Action: Liothyronine is a synthetic version of the T3 thyroid hormone. It replaces or provides more thyroid hormone, which is essential for regulating the body's energy and metabolism.
- Key Considerations: Dosage must be carefully controlled, as too much can cause symptoms of an overactive thyroid (hyperthyroidism), including rapid heartbeat, anxiety, and weight loss. Regular blood tests are needed to ensure the dosage is correct.
Comparison of Pills with "D17" Imprint
To avoid dangerous confusion, this table summarizes the key differences between medications carrying the "d17" imprint.

Conclusion: Your Health Comes First
The answer to "What is the pill d17 used for?" is not singular. This imprint is a clear example of why visual identification of medication is unreliable and potentially hazardous. The five different drugs associated with this code treat vastly different conditions, from high blood pressure to HIV to allergies. Mistaking one for another could have serious health consequences. Always verify your medication with the information on your prescription bottle and consult your pharmacist with any questions or discrepancies. Your pharmacist is the most reliable resource for confirming a pill's identity and ensuring your safety.
