What happens if I miss a dose?

Since cough or cold medicine is taken when needed, you may not be on a dosing schedule. If you are taking the medication regularly, take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.

What happens if I overdose?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

Overdose symptoms may include feeling restless or nervous, nausea, vomiting, stomach pain, dizziness, drowsiness, dry mouth, warmth or tingly feeling, or seizure (convulsions).

What should I avoid while taking brompheniramine, dextromethorphan, and pseudoephedrine?

This medication may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert.

Drinking alcohol can increase certain side effects of brompheniramine, dextromethorphan, and pseudoephedrine.

Avoid taking this medication if you also take diet pills, caffeine pills, or other stimulants (such as ADHD medications). Taking a stimulant together with a decongestant can increase your risk of unpleasant side effects.

Ask a doctor or pharmacist before using any other cough, cold, or allergy medicine. Brompheniramine, dextromethorphan, and pseudoephedrine are contained in many combination medicines. Taking certain products together can cause you to get too much of a certain drug. Check the label to see if a medicine contains an antihistamine, cough suppressant, or decongestant.

What other drugs will affect brompheniramine, dextromethorphan, and pseudoephedrine?

Before using this medication, tell your doctor if you regularly use other medicines that make you sleepy (such as other cold or allergy medicine, sedatives, narcotic pain medicine, sleeping pills, muscle relaxers, and medicine for seizures, depression, or anxiety). They can add to sleepiness caused by brompheniramine.

Tell your doctor about all other medications you use, especially:

• a diuretic (water pill), or blood pressure medicine;
• medication to treat irritable bowel syndrome;
• bladder or urinary medications such as oxybutynin (Ditropan, Oxytrol), darifenacin (Enablex), or tolterodine (Detrol);
• salicylates such as aspirin, Backache Relief Extra Strength, Novasal, Nuprin Backache Caplet, Doan's Pills Extra Strength, Pepto-Bismol, Tricosal, and others;
• a beta-blocker such as atenolol (Tenormin, Tenoretic), carvedilol (Coreg), labetalol (Normodyne, Trandate), metoprolol (Lopressor, Toprol), nadolol (Corgard), propranolol (Inderal, InnoPran), sotalol (Betapace), and others; or
• antidepressants such as amitriptyline (Elavil, Vanatrip), clomipramine (Anafranil), doxepin (Sinequan), imipramine (Janimine, Tofranil), nortriptyline (Pamelor), and others.

This list is not complete and there may be other drugs that can interact with brompheniramine, dextromethorphan, and pseudoephedrine. Tell your doctor about all the prescription and over-the-counter medications you use. This includes vitamins, minerals, herbal products, and drugs prescribed by other doctors. Do not start using a new medication without telling your doctor.
