What is Theraflu Warming Severe Cold Daytime?

Acetaminophen is a pain reliever and fever reducer.

Dextromethorphan is a cough suppressant. It affects the signals in the brain that trigger cough reflex.

Phenylephrine is a decongestant that shrinks blood vessels in the nasal passages. Dilated blood vessels can cause nasal congestion (stuffy nose).

Theraflu Warming Severe Cold Daytime is a combination medicine used to treat headache, fever, body aches, cough, stuffy nose, and sinus congestion caused by allergies, the common cold, or the flu.

Theraflu Warming Severe Cold Daytime will not treat a cough that is caused by smoking, asthma, or emphysema.

Theraflu Warming Severe Cold Daytime may also be used for purposes not listed in this medication guide.

Measure liquid medicine with a special dose measuring spoon or medicine cup, not with a regular table spoon. If you do not have a dose measuring device, ask your pharmacist for one.

What happens if I miss a dose?

Since Theraflu Warming Severe Cold Daytime 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.

Avoid drinking alcohol. It may increase your risk of liver damage while you are taking acetaminophen.
