Antilirium affects chemicals in the body that control the signals sent from the nervous system to the muscles to activate muscle movement.

Antilirium is used to reverse the effects of certain drugs or substances that interfere with this nerve-muscle communication. Such substances include atropine, scopolamine, belladonna, antihistamines, some antidepressants, and other anticholinergic (AN tye KOE lin ER jik) drugs.

Antilirium may also be used for purposes not listed in this medication guide.

In an emergency situation it may not be possible to tell your caregivers about your health conditions. Make sure any doctor caring for you afterward knows you have received Antilirium.

Antilirium is injected into a muscle or into a vein through an IV. A healthcare provider will give you this injection.

When injected into a vein, Antilirium must be given slowly.

Your breathing, blood pressure, oxygen levels, and other vital signs will be watched closely while you are receiving Antilirium.

You may need repeat doses of Antilirium, depending on how your body responds to it. Your doctor will determine how long to treat you with Antilirium.

You should not be treated with Antilirium if you are allergic to it, or if you have:

• asthma;

• diabetes;

• bladder obstruction or other urination problems;

• a blockage in your digestive tract (stomach or intestines);

• heart disease; or

• gangrene (damaged skin and muscle tissue caused by infection or lack of blood supply).

If possible before you receive Antilirium, tell your doctor if:

• you have a sulfite allergy;

• you have recently taken Ultracet (acetaminophen with tramadol); or

• you regularly take bupropion (Wellbutrin, Zyban, Aplenzin, Forfivo, and others).

In an emergency situation it may not be possible to tell your caregivers if you are pregnant or breast-feeding. Make sure any doctor caring for your pregnancy or your baby knows you have received this medicine.

Because you will receive Antilirium in a clinical setting, you are not likely to miss a dose.

Since Antilirium is given by a healthcare professional in a medical setting, an overdose is unlikely to occur.

Follow your doctor's instructions about any restrictions on food, beverages, or activity.

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

Tell your caregivers right away if you have:

• increased urination or bowel movements;

• stomach cramps;

• severe or worsening nausea or vomiting;

• increased sweating;

• blurred vision; or

• excessive saliva in your mouth.

Common side effects of Antilirium may include:

• nausea, vomiting;

• increased salivation; or

• slow heartbeats.

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.

Other drugs may interact with physostigmine, including prescription and over-the-counter medicines, vitamins, and herbal products. Tell each of your health care providers about all medicines you use now and any medicine you start or stop using.
