The main side effects of Viridian involve the digestive and endocrine systems. The generic name for Viridian is morinoguanidine, which has antiviral properties. Clinically, morinoguanidine is mainly used to treat viral infections such as viral influenza and various types of herpes. Oral administration of morinoguanide may cause digestive side effects such as nausea, vomiting, diarrhea, loss of appetite, etc. An overdose of morinoguanide can also cause symptoms such as dry mouth and excessive sweating. The chemical structure of morinoguanidine is extremely similar to the glucose-lowering drug metformin. Oral morinoguanidine may cause hypoglycemia, especially in older people with diabetes, and if symptoms such as panic, shaking hands, profuse sweating, or hunger occur during the course of taking the drug, stop taking the drug immediately and go to your local healthcare facility.
