A patient must never administer esmolol injection by himself.

• Esmolol interacts with many medications. Make sure that your doctor is informed about your ongoing medications/ supplements, herbal preparations before it is administered.
• Esmolol can mask the symptoms of low blood sugar levels in diabetic patients.

Esmolol should be administered with extreme precaution, if the patient suffers from one of the following conditions:
• Diabetes, since it may mask the effects of low blood sugar levels
• Low blood sugar
• Low blood pressure
• Kidney function problems, since the drug is eliminated from the body in the urine
• Respiratory problems like asthma, bronchitis, and emphysema
• Pheochromocytoma, which is a tumor of the adrenal glands that secretes large amounts of adrenaline
• Prinzmetal’s angina, where angina occurs due to spasm of a coronary artery
• Metabolic acidosis
• Hyperthyroidism, or high thyroid hormone levels
• Poor circulation
• Hypovolemic patient, where the blood volume is low

Esmolol should be avoided with:
• Other beta blockers due to additive effects.
• Other drugs that can slow down the heart like verapamil, digitalis, amiodarone and diltiazem.
• Drugs used in the treatment of asthma due to opposite effects on the bronchi
• Antidiabetes medications since esmolol can block the signs of hypoglycemia
• Drugs that act on alpha receptors. Along with alpha agonists like ephedrine, it can produce excessive rise in blood pressure, while with alpha blockers like prazosin, it can result in excess fall in blood pressure
• NSAIDs like ibuprofen and naproxen, which may block the effect of esmolol on blood pressure.
• Anticholinesterase drugs used in Alzheimer's disease like rivastigmine due to additive effect on the heart and blood pressure
• Drugs that lower blood pressure and increase potassium levels like chlorthiazide
• Other drugs that may lower blood pressure like antihypertensive medications, aldesleukin, and barbiturates.
