Do not use a cough or cold medicine if you have used an MAO inhibitor such as isocarboxazid (Marplan), phenelzine (Nardil), rasagiline (Azilect), selegiline (Eldepryl, Emsam), or tranylcypromine (Parnate) within the past 14 days. Serious, life-threatening side effects can occur if you take cough or cold medicine before the MAO inhibitor has cleared from your body.
Do not give this medication to a child younger than 6 years old. Always ask a doctor before giving cough or cold medicine to a child. Death can occur from the misuse of cough or cold medicine in very young children.
Before using this medication, tell your doctor if you regularly use other medicines that make you sleepy (such as other cold or allergy medicine, narcotic pain medicine, sleeping pills, muscle relaxers, and medicine for seizures, depression, or anxiety). They can add to sleepiness caused by chlophedianol, guaifenesin, and pseudoephedrine.
This medication can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert.
Talk with your doctor if your symptoms do not improve after 7 days of treatment, or if you have a fever with a headache or skin rash.
Chlophedianol is a cough suppressant. It reduces muscle spasms associated with the cough reflex.
Guaifenesin is an expectorant. It helps loosen mucus congestion in your chest and throat, making it easier to cough out through your mouth.
Pseudoephedrine is a decongestant that shrinks blood vessels in the nasal passages. Dilated blood vessels can cause nasal congestion (stuffy nose).
The combination of chlophedianol, guaifenesin, and pseudoephedrine is used to treat cough, chest congestion, and nasal congestion caused by the common cold.
Chlophedianol will not treat a cough that is caused by smoking, asthma, or emphysema.
Chlophedianol, guaifenesin, and pseudoephedrine may also be used for other purposes not listed in this medication guide.

Serious, life-threatening side effects can occur if you take cough or cold medicine before the MAO inhibitor has cleared from your body.
