The reference price of Carvedilol ranges from $11.0 to $44.0. Because this drug is divided into imported and domestic, and there are more dosage forms and specifications of the drug, and the charging policy of each region is also different, so the specific cost varies greatly.

Adverse reactions are more commonly dizziness, headache, fatigue, and occasionally abdominal pain, diarrhea, and nausea. This medication is contraindicated in cases of tracheospasm, second or third degree AV block, sick sinus node syndrome, cardiogenic shock, severe bradycardia, and severe hepatic insufficiency.
