What alternative treatments or formulations are available for a patient with persistent Vitamin D deficiency who experiences severe gastrointestinal side effects from oral cholecalciferol, and would an active form like calcitriol be a safe and effective option?
Instead of oral cholecalciferol tablets, we can try liquid drops, which are often much gentler on the stomach, or even a prescription injection. Another option is ergocalciferol. Regarding calcitriol, because it is the active form of vitamin D, it acts very quickly and carries a higher risk of raising your calcium levels too much. It is typically reserved for specific conditions like kidney disease. I highly recommend discussing liquid formulations or an injection with your doctor to find a comfortable, safe solution for you.
