What happens if I miss a dose (Phenylhistine DH Expectorant)?
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 (Phenylhistine DH Expectorant)?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. An overdose of codeine can be fatal.
Overdose symptoms may include extreme dizziness or drowsiness, confusion, feeling restless or nervous, cold and clammy skin, warmth or tingly feeling, nausea, vomiting, weak or shallow breathing, slow heart rate, pinpoint pupils, fainting, or seizure (convulsions).
What should I avoid while taking chlorpheniramine, codeine, and pseudoephedrine (Phenylhistine DH Expectorant)?
This medication may cause blurred vision or impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert and able to see clearly.
Do not take this medication with alcohol, other narcotic medications, sedatives, tranquilizers, muscle relaxers, or other medicines that can make you sleepy or slow your breathing. Dangerous side effects may result.
Drinking alcohol can increase drowsiness caused by chlorpheniramine or codeine.
Avoid becoming overheated or dehydrated during exercise and in hot weather.
Ask a doctor or pharmacist before using any other cold, cough, allergy, or pain medicine. Chlorpheniramine, pseudoephedrine, 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.
Avoid taking diet pills, caffeine pills, or other stimulants (such as ADHD medications) without your doctor's advice. Taking a stimulant together with a decongestant can increase your risk of unpleasant side effects.
