These may further cause a tingling sensation and numbness in hands and feet, weakness, urinary problems, change in mental status and difficulty in maintaining balance (ataxia).

The symptoms are more likely to be noticed if you miss or delay your food, drink alcohol, over-exercise or take any other antidiabetic medicine along with it. Hence, regular monitoring of blood sugar level is important. It is recommended to always carry glucose tablets, honey or fruit juice with you.

Symptoms of lactic acidosis may include muscle pain or weakness, dizziness, tiredness, feeling of cold in arms and legs, difficulty in breathing, nausea, vomiting, stomach pain or slow heart rate. If you have these symptoms, stop taking Tenglyn M and immediately consult your doctor.
