Long-term consumption of methylcobalamin tablets may cause harm to the body, but the general harm is small.
The main ingredient of methylcobalamin tablets is methylcobalamin, which is a water-soluble vitamin mainly used for the treatment of peripheral neuropathy, and it can be excreted with urine when renal function is normal, so the side effects are relatively small, but it can lead to gastrointestinal discomforts such as vomiting, nausea, and abdominal pain in case of long term overconsumption.
Allergic reactions such as skin rash can occur in a small number of patients. Please stop the drug promptly if it occurs. In addition, a small number of patients can experience loss of appetite, nausea, vomiting, abdominal pain, diarrhea and other symptoms. The use of methylcobalamin is prohibited for those who are allergic to methylcobalamin or other ingredients in the medicine.
If taking methylcobalamin tablets for a month or longer does not have any effect, it is recommended to stop taking the medicine and actively seek medical advice to find out the cause. Workers who are exposed to mercury or other compounds should not take large quantities of methylcobalamin tablets for a long period of time.
Methylcobalamin tablets as a medicine should be used under the guidance of a doctor to maximize the avoidance of side effects and ensure the safety of medication.
