What happens if I miss a dose?
Since cold medicine is taken as 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 some of the serious side effects listed in this medication guide.
What should I avoid while taking chlorpheniramine and phenylephrine?
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 chlorpheniramine and phenylephrine.
Ask a doctor or pharmacist before using any other cold, allergy, or sleep medicine. Chlorpheniramine and phenylephrine 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 or decongestant.
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.
What other drugs will affect chlorpheniramine and phenylephrine?
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 chlorpheniramine.
Tell your doctor about all other medications you use, especially:
- mecamylamine (Inversine);
- methyldopa (Aldomet);
- 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;
- a barbiturate such as butabarbital (Butisol), secobarbital (Seconal), pentobarbital (Nembutal), or phenobarbital (Solfoton); or
- an antidepressant such as amitriptyline (Elavil, Vanatrip), doxepin (Sinequan), nortriptyline (Pamelor), and others.
This list is not complete and other drugs may interact with chlorpheniramine and phenylephrine. Tell your doctor about all medications you use. This includes prescription, over-the-counter, vitamin, and herbal products. Do not start a new medication without telling your doctor.
Where can I get more information?

Remember, keep this and all other medicines out of the reach of children, never share your medicines with others, and use this medication only for the indication prescribed.
