TRIMETHOBENZAMIDE - INJECTION

(try-meth-oh-BENZ-uh-mide)

COMMON BRAND NAME(S): Tigan

Uses

This medication is used to treat nausea and vomiting.

How To Use

This medication is used through intramuscular injection (IM).

Side Effects

Diarrhea, headache, dizziness, drowsiness, dry mouth, or muscle cramps may occur as your body adjusts to the medication. If these effects persist or become bothersome, inform your doctor. Notify your doctor if you experience any of the following: unusual bleeding, depression, confusion, tremors, involuntary movements of the eyes/face/limbs, muscle spasms, rash, mouth sores, yellowing of the skin or eyes, blurred vision.

Precautions

Tell your doctor your medical history, especially: high fever, stomach problems (gastroenteritis), swelling/disease of the brain (encephalitis/encephalopathy), mineral (electrolyte) imbalance, any allergies. Do not give children trimethobenzamide to treat vomiting when the cause of vomiting is unknown. Trimethobenzamide may worsen Reye's Syndrome, a rare but serious illness. Do not give trimethobenzamide (or aspirin or acetaminophen) to a child with symptoms of Reye's Syndrome (sudden, severe, persistent vomiting; drowsiness or stupor; unusual behavior; and seizures). Call the doctor immediately if these symptoms are present. Children and teenagers should not use this drug if they have chickenpox, influenza, or any undiagnosed illness without first consulting a doctor about Reye's syndrome. If dizziness or drowsiness occurs, use caution engaging in activities requiring alertness such as driving. Limit alcohol because it adds to the dizziness/drowsiness effects of trimethobenzamide. This injectable form of trimethobenzamide is not recommended for use in children. This medication should be used only when clearly needed during pregnancy. Discuss the risks and benefits with your doctor. It is not known if this medication is excreted into breast milk. Consult your doctor before breast-feeding.
