What happens if I miss a dose (Viravan-PDM)?

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 (Viravan-PDM)?

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

Overdose symptoms may include feeling restless or nervous, extreme drowsiness, confusion, weak or shallow breathing, and seizure (convulsions).

What should I avoid while taking dextromethorphan, pseudoephedrine, and pyrilamine (Viravan-PDM)?

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 dextromethorphan, pseudoephedrine, and pyrilamine.

Ask a doctor or pharmacist before using any other cold, cough, or allergy medicine. Antihistamines, decongestants, and cough suppressants 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, decongestant, or cough suppressant.

What other drugs will affect dextromethorphan, pseudoephedrine, and pyrilamine (Viravan-PDM)?

Before using this medication, tell your doctor if you regularly use other medicines that make you sleepy (such as 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 dextromethorphan or pyrilamine.

This list is not complete and other drugs may interact with dextromethorphan, pseudoephedrine, and pyrilamine. 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.
