Neomycin, colchicine, para-aminosalicylic acid, or excessive alcohol intake longer than two weeks may cause malabsorption of vitamin B12. Chloramphenicol and other drugs having bone marrow suppressant properties may cause a lack of therapeutic response to vitamin B12
Other lipotropic injection side effects include: Headaches and light headedness Stomach upsets such as mild nausea and mild diarrhea Allergic reactions (itching, hives, shortness of breath, wheezing, swelling of the tongue, throat, or mouth) although rare, can also occur

Liposomal delivery systems encapsulate AHK-Cu in lipid spheres, potentially improving penetration through the stratum corneum and protecting the peptide from degradation
