Trembling in your fingers can indeed be a side effect of Glimisave M-3. This medication contains glimepiride, which can significantly lower your blood sugar levels. Shaking or trembling is a classic symptom of low blood sugar (hypoglycemia), which may also be accompanied by sweating, anxiety, or dizziness. When you experience this trembling, please check your blood sugar level immediately. If it is below 70 mg/dL, consume 15 grams of fast-acting sugar (like fruit juice or sweets) and recheck in 15 minutes. You should consult your prescribing doctor promptly to discuss adjusting your dose, as taking this medication twice daily may require medical reassessment.
