Identifying a medication by its markings is a common practice, but it requires careful attention to detail. The imprint '747' can be particularly misleading because it is associated with different active ingredients, forms, and manufacturers. Therefore, comparing the pill's physical characteristics to database images is the only safe way to determine what medication you may have. Below is a breakdown of the most common medications associated with the '747' imprint.
Duloxetine Hydrochloride Delayed-Release (B 747)
One medication often identified with the imprint 'B 747' is a 30 mg duloxetine capsule, which is green and white. Duloxetine is an SNRI used to treat various conditions, including major depressive disorder (MDD), generalized anxiety disorder (GAD), fibromyalgia (FM), diabetic peripheral neuropathic pain (DPNP), and chronic musculoskeletal pain.
Some generic duloxetine capsules manufactured by Breckenridge Pharmaceutical have been recalled in 2024 and 2025 due to a nitrosamine impurity called N-nitroso-duloxetine. This impurity may pose a cancer risk if exposure is above acceptable limits over time. If you possess these capsules, check the lot number and consult a healthcare provider. Common side effects of duloxetine include nausea, dry mouth, constipation, drowsiness, loss of appetite, and increased sweating.
Desvenlafaxine Fumarate Extended-Release (747 Pink, Round)
A pink, round, 50 mg desvenlafaxine extended-release tablet also uses the imprint '747'. Desvenlafaxine is another SNRI approved for treating MDD in adults. Common side effects include nausea, dry mouth, insomnia, constipation, and dizziness.
Tiadylt ER / Diltiazem Hydrochloride (747 Blue & Pink)
The imprint '747' also appears on a blue and pink 240 mg capsule of Tiadylt ER, which is diltiazem hydrochloride. Diltiazem is a calcium channel blocker used for cardiovascular conditions such as high blood pressure and angina. It may also be used in some cases of heart failure. Common side effects include dizziness, headache, weakness, fatigue, and nausea.
