IN THIS ARTICLE

What should I discuss with my healthcare provider before taking acetaminophen, pheniramine, and phenylephrine (Flu & Severe Cold Night Time, Theraflu Cold & Sore Throat, Theraflu Flu & Sore Throat, Theraflu Nighttime Severe Cold, Theraflu Sinus & Cold)?

Ask a doctor before taking medicine that contains acetaminophen if you have ever had liver disease, or if you drink more than 3 alcoholic beverages per day.

You should not use this medication if you are allergic to acetaminophen (Tylenol) or chlorpheniramine, or if you have:

  • severe constipation, blockage in your stomach or intestines;
  • untreated or uncontrolled diseases--glaucoma, asthma or COPD, heart disease, high blood pressure, coronary artery disease, overactive thyroid; or
  • if you are unable to urinate.

Do not use cold or allergy medicine if you have taken an MAO inhibitor in the past 14 days. A dangerous drug interaction could occur. MAO inhibitors include furazolidone, isocarboxazid, linezolid, phenelzine, rasagiline, selegiline, and tranylcypromine.

Ask a doctor or pharmacist if it is safe for you to take acetaminophen, pheniramine, and phenylephrine if you have other medical conditions, especially:

It is not known whether acetaminophen, pheniramine, and phenylephrine will harm an unborn baby. Do not use cold or allergy medicine without a doctor's advice if you are pregnant.

This medicine may pass into breast milk and may harm a nursing baby. Antihistamines and decongestants may also slow breast milk production. Do not use cold or allergy without a doctor's advice if you are breast-feeding a baby.

Always ask a doctor before giving a cold or allergy medicine to a child. Death can occur from the misuse of cough and cold medicines in very young children.

How should I take acetaminophen, pheniramine, and phenylephrine (Flu & Severe Cold Night Time, Theraflu Cold & Sore Throat, Theraflu Flu & Sore Throat, Theraflu Nighttime Severe Cold, Theraflu Sinus & Cold)?

Use exactly as directed on the label, or as prescribed by your doctor. Do not use for longer than recommended. Cold or allergy medicine is usually taken only for a short time until your symptoms clear up.

Do not take more of this medication than is recommended. An overdose of acetaminophen can damage your liver or cause death.

Dissolve the contents of one packet of medicine in 8 ounces of hot water. You may also mix the powder with 8 ounces of cool water and heat the mixture in a microwave oven. Stir the mixture thoroughly before and after heating it. Sip the mixture slowly, making sure you finish all of it within 10 to 15 minutes.

Do not take more than 6 packets of this medicine in one day (24 hours).

Call doctor if your symptoms do not improve after 7 days of treatment, or if you have a fever with a headache, cough, or skin rash.

This medication can cause unusual results with allergy skin tests. Tell any doctor who treats you that you are taking an antihistamine.

Store at room temperature away from moisture and heat.
