Yes, it is safe to split your Stamlo 2.5 (amlodipine 2.5 mg tablet) as advised by your doctor. Since these are immediate-release tablets, splitting them will not alter how the medication works. To do this safely, please follow these precautions. Use a pill cutter: Use a clean pill splitter from a pharmacy to ensure an equal, accurate half dose rather than a knife. Storage: Store the unused half in a dry, airtight container and consume it the next day. Monitor: Keep tracking your blood pressure at home. If you experience dizziness, lightheadedness, or unusual fatigue, consult your doctor promptly.\n\nDo not stop the medication completely without consulting your physician.
