Brompheniramine-Pseudoephedrine-Dextromethorphan Risks, Warnings, and Complications

Brompheniramine-Pseudoephedrine-Dextromethorphan can cause serious medical problems in certain people. You may opt-out of taking this medicine if you are at a high risk of complications. Some of the risks of brompheniramine-pseudoephedrine-dextromethorphan use include:

ACCIDENTAL OVERDOSE: Antihistamines are present in many over-the-counter cold and allergy medications. As this medicine has an antihistamine (brompheniramine), it is easy to unintentionally consume many antihistamines. It can be hazardous to take more than one antihistamine at once. Overdosing on antihistamines can result in convulsions, hallucinations, and even death. These kinds of drugs carry a higher risk of overdose in infants and young children. Always confirm the safety of using additional cold and allergy medications with this medication with your doctor or pharmacist first.
DROWSINESS: Brompheniramine-Pseudoephedrine-Dextromethorphan can make you drowsy and affect your ability to think clearly. The risk is higher in people who consume alcohol or are taking other medications that can cause drowsiness, such as an opioid pain reliever, benzodiazepine (tranquilizer), or sleeping pill. Be careful while doing anything that requires your complete attention, such as driving or operating machinery, until you know how this drug affects you.
DANGEROUS DRUG INTERACTION: Do not use brompheniramine-pseudoephedrine-dextromethorphan if you are currently consuming or recently consumed within the past 14 days monoamine oxidase inhibitors (MAO) drugs, such as selegiline, phenelzine, or tranylcypromine. When used with MAO inhibitors, brompheniramine-pseudoephedrine-dextromethorphan can result in hazardous changes in your blood pressure.
HYPERACTIVITY IN CHILDREN: Brompheniramine-pseudoephedrine-dextromethorphan typically makes adults sleepy; however, it can have the reverse effect on children and make them hyper and excited. Speak with your child's doctor to discuss alternative options if they are experiencing problems sleeping after starting this medicine.
SEROTONIN SYNDROME: Too much serotonin in the brain causes the rare but potentially fatal illness known as serotonin syndrome. If you combine brompheniramine-pseudoephedrine-dextromethorphan with other drugs that influence serotonin levels (such as lithium, some Parkinson's disease treatments, or antidepressants), your risk increases. Before beginning treatment with brompheniramine-pseudoephedrine-dextromethorphan, inform your pharmacist of all prescription and over-the-counter medications you are currently taking so they may check for potential interactions. A rapid heartbeat, sweating, muscle stiffness or spasms, fever, and confusion are signs of an excess of serotonin. If you have any of these symptoms, tell your doctor or get emergency medical help.
