Taking cyanocobalamin with other medicines and herbal supplements - Brand name: Orobalin

Cautions with other medicines

Cyanocobalamin is usually safe to take with other medicines, including painkillers.

Some medicines may reduce the amount of cyanocobalamin you absorb from the tablets or from the food you eat. This will not usually have a noticeable effect. However, tell your doctor or pharmacist if you're taking:

• metformin for diabetes
• antacids like Gaviscon
• H2 blockers like ranitidine, cimetidine, famotidine or nizatidine
• proton pump inhibitors (PPIs) like lansoprazole, omeprazole, pantoprazole or rabeprazole

Mixing cyanocobalamin with herbal remedies and supplements

There's not enough information to say that complementary medicines, herbal remedies and supplements are safe to take with cyanocobalamin. They're not tested in the same way as pharmacy and prescription medicines. They're generally not tested for the effect they have on other medicines.
