Mechanism of Action
Supports keratin infrastructure, the structural protein that forms hair, skin, and nails. Also supports fatty acid synthesis needed for healthy cell membranes and skin barrier function.
Injection

FAQs
What is Biotin?
Biotin is a prescription therapy used for hair and nail support.
Who should use Biotin?
Patients seeking support for hair and nail support may qualify after evaluation by a licensed provider.
Does Biotin Injection require a prescription?
Yes. Injectable biotin is a compounded medication requiring a valid prescription from a licensed provider.
What are the possible side effects?
Biotin is generally very well tolerated. Injection site discomfort is the most common side effect. High doses can interfere with certain lab tests.
Who should not use Biotin Injection?
Contraindicated in patients with known hypersensitivity to biotin. Use with caution in patients undergoing thyroid or cardiac lab testing, as high-dose biotin can interfere with immunoassay-based results. Use during pregnancy or breastfeeding requires provider evaluation, as safety at high injectable doses has not been established.
Are there any drug interactions?
Anticonvulsants such as carbamazepine and phenytoin can reduce biotin levels. Inform your provider if you are taking these medications.
Is Biotin Injection safe if I have a pre-existing medical condition?
Biotin is safe for most patients. Those with pending lab work (thyroid, troponin) should inform their provider, as high-dose biotin may cause false results on immunoassay-based tests.
