Medication Alert: Beta‑Blockers & Hidden Lows

Like the wolf in Red Riding Hood, beta‑blockers can disguise your body’s adrenaline alarm, making hypoglycemia harder to notice.

  • Blunted warnings: fast heartbeat, tremor, and anxiety may be muted; sweating can still happen.
  • What to do: rely on your meter/CGM and treat lows right away—don’t wait for symptoms.
Common beta‑blockers (examples)
  • Metoprolol (Lopressor, Toprol‑XL)
  • Atenolol (Tenormin)
  • Bisoprolol (Zebeta)
  • Nadolol (Corgard)
  • Carvedilol (Coreg)
  • Sotalol (Betapace)
  • Timolol (Blocadren)
  • Nebivolol (Bystolic)
  • Propranolol (Inderal, Hemangeol)
Do not stop these medications unless advised by your healthcare team. Be extra vigilant while using them.
