“Most commercially available B12 injections use cyanocobalamin, a form your body still has to convert; methylcobalamin is the active, body-ready form. It also bypasses the absorption question that comes with oral and sublingual B12, making it a strong option if you have tried those and still feel unsure. Methyl, cyano, pill, under the tongue, injection - confused? We get it. Let us help.”— Nathan Parker, MintRx Pharmacist

Important safety information
Methylcobalamin B12 Injection is a compounded sterile prescription medication at 5 mg/mL. Compounded medications are not FDA-approved, and the FDA does not verify their safety, effectiveness, or quality before marketing. Do not use with known hypersensitivity to methylcobalamin, cobalamin, cobalt, or any vial component. Tell the provider about Leber hereditary optic neuropathy, polycythemia vera, severe anemia, low potassium, kidney or liver disease, pregnancy, breastfeeding, and all medicines. Chloramphenicol can interfere with hematologic response. Rapid treatment of severe B12-deficiency anemia can cause clinically significant hypokalemia and may require monitoring. Injection-site pain, redness, soreness, bruising, headache, GI upset, and temporary urine-color change may occur. The solution is naturally bright pink/red; follow the pharmacy guidance for acceptable appearance. Seek emergency care for trouble breathing, facial or throat swelling, fainting, severe rash, vision change, severe weakness, palpitations, or signs of injection-site infection. Use sterile supplies and the prescribed SubQ or IM technique; rotate sites and never share needles or vials. Refrigerate after receipt at 36–46°F (2–8°C), protect from light in the original carton, and do not freeze. Do not use if cloudy, unexpectedly discolored, damaged, or containing particles. Record the first-use date and obey the pharmacy-labeled expiration/BUD; the documented 180-day BUD from compounding controls even if medication remains. Keep out of reach of children. Benefits are most likely when deficiency or impaired absorption is present; no energy, weight-loss, cognitive, mood, neuropathy, athletic, or anti-aging outcome is guaranteed.
