1. Do NOT restart Ciplar LA 20 on your own — but do contact the prescribing doctor today or tomorrow (the one who gave it for 2 weeks).
Tell them exactly: • Stopped after completing 2 weeks • Heart rate now >100 bpm • Feeling and hearing heartbeat strongly • Mild chest pain/discomfort • Unable to sleep because of it 2. Doctor will most likely: • Either restart low-dose propranolol (e.g., Ciplar LA 20 or plain 10–20 mg) and taper slowly over 1–2 weeks • Or switch to a shorter-acting beta-blocker (like propranolol 10 mg SOS) for breakthrough episodes • Or add a short course of anti-anxiety medicine (e.g., low-dose clonazepam or escitalopram) if anxiety is amplifying the sensation • Possibly ask for ECG or Holter monitor if they suspect arrhythmia (though from your description it sounds like sinus tachycardia) 3. Go to emergency / hospital same day only if: • Heart rate stays >120–130 bpm even at rest for hours • Chest pain becomes severe, squeezing, or crushing • You get shortness of breath, sweating, nausea, dizziness/fainting • Irregular heartbeat feeling (skipping beats)

• Calm the heart rate & sensation immediately • Sit or lie down in a quiet, cool room • Practice 4-7-8 breathing: inhale 4 seconds → hold 7 seconds → exhale slowly 8 seconds → repeat 5–10 cycles • Sip cold water slowly — sometimes helps reduce awareness of heartbeat • Avoid caffeine, tea, energy drinks, chocolate completely today • Measure heart rate properly • Use finger on wrist or neck (not oximeter at night — it can be inaccurate when anxious) • Count for full 60 seconds — write time + rate every 30–60 min if worried • Sleep help tonight • Sleep semi-reclined (2 pillows) — reduces heart awareness for many people • Keep room cool and dark • No phone/screens 1 hour before bed • Avoid • Sudden stopping of beta-blockers in future — always taper under doctor guidance • Self-medicating with other heart/BP medicines This rebound phase usually lasts 3–10 days and then settles as your body adjusts. Once you speak to the doctor, they will either restart/taper the medicine or give a better plan — most people feel back to normal very quickly after that. Please contact the doctor today (call or visit) — and update me if you want help explaining your symptoms to them or understanding their new prescription. You are safe — this is a known and temporary effect of stopping the medicine. Take care and breathe slowly
