Hydroxycobalamin (HCO) injections are sometimes used to treat low levels of vitamin B-12 and folic acid in pregnant women. When used as a standalone treatment, HCO injections have no effect on contraception. However, they may interfere with some forms of contraception.If you’re on a hormonal contraceptive such as an IUD or a subdermal implant, HCO injections could temporarily make these methods less effective. If you’re taking a combined contraceptive pill, HCO injections may make it less effective, but it may still be a good option for you.HCO injections can also affect some non-hormonal contraception methods, such as a diaphragm or condoms that are dipped in spermicide. HCO injections may reduce the effectiveness of these methods by lowering the amount of spermicide on the condom or diaphragm. If you’re not sure which contraception method is best for you, talk to your doctor about the risks of HCO injections on each method.
