Frequently Asked Questions

Concor Tablet ke aam nuksanat kya hain?

The most common side effects of Concor are fatigue, cold hands and feet, a slower heart rate (bradycardia), and dizziness on standing. These are usually manageable at standard doses.

Kya Concor se dil ki dhadkan bahut slow ho sakti hai?

Yes. Bisoprolol reduces heart rate — this is its intended effect. A resting heart rate of 50–60 bpm is expected and acceptable. However, if the heart rate falls below 45–50 bpm or you feel faint, contact your doctor immediately.

Kya Concor asthma mein use kar sakte hain?

Bisoprolol should generally be avoided in asthma and severe COPD. Even cardioselective beta-blockers can trigger bronchospasm, especially at higher doses. Consult your doctor for a safe alternative.

Kya Concor diabetes mein safe hai?

Concor can be used in diabetics but requires careful monitoring. Bisoprolol can mask tachycardia, which is an important warning sign of hypoglycaemia. Monitor blood glucose more frequently and watch for non-cardiac signs of low blood sugar (sweating, shakiness).

Kya Concor band karna safe hai?

No. Never stop Concor suddenly. Abrupt withdrawal can trigger rebound hypertension, worsening angina, and potentially serious cardiac events. Always taper the dose gradually over 1–2 weeks under your doctor's supervision.
