Isoproterenol injection

Isoproterenol is used to treat heart block, heart failure, shock, and cardiac arrest.

Isoproterenol is also used to treat bronchospasm that may happen while you are under anesthesia.

Isoproterenol may be used along with other medicines.

Isoproterenol may also be used for reasons not mentioned in this medication guide.

In an emergency, you might not be able to inform caregivers about your health conditions. Ensure that any doctor treating you afterward is aware that you received isoproterenol injection.

You may not be treated with isoproterenol if you have:

• heart problems caused by using too much digoxin (digitalis);
• chest pain (angina); or
• certain heart rhythm disorders.

If possible, tell your doctor about all your medical conditions or allergies before you receive isoproterenol.

In an emergency, you may not be able to inform caregivers if you are pregnant or breastfeeding. Ensure that any doctor caring for your pregnancy or your baby knows you received this medicine.

Get emergency medical help if you have signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Tell your caregivers right away if you have:

• pounding heartbeats or fluttering in your chest;
• chest pain;
• severe headache, pounding in your neck or ears;
• pain when you breathe, shortness of breath, cough;
• pale skin, cold and clammy skin, anxiety; or
• a light-headed feeling, like you might pass out.

Common side effects of isoproterenol injection may include:

• headache, dizziness, nervousness;
• nausea;
• blurred vision;
• tremors; or
• sweating, flushing (sudden warmth, redness, or tingly feeling).

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Isoproterenol is injected under the skin or into a muscle, or given as an infusion into a vein. A healthcare provider will give you this injection.

Your breathing, blood pressure, oxygen levels, kidney function, and other vital signs will be watched closely.

Because you will get isoproterenol injection in a clinical setting, you are not likely to miss a dose.

Since isoproterenol injection is administered by a healthcare professional in a medical setting, the chance of an overdose is low. If an overdose happens, you might experience chest pain, fast or pounding heartbeats, and you may feel light-headed.

Follow your doctor's instructions regarding any restrictions on food, drinks, or activities.

Other drugs may affect isoproterenol injection, including prescription and over-the-counter medicines, vitamins, and herbal products. Tell your doctor about all your current medicines and any medicine you begin or stop using.
