Theraflu helps control cold and flu symptoms. But it doesn't kill the virus causing your infection. Theraflu is a combination of several common over-the-counter (OTC) medications.

Drowsiness, dizziness, constipation, stomach upset, blurred vision, or dry mouth/nose/throat may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly. To relieve dry mouth, suck (sugarless) hard candy or ice chips, chew (sugarless) gum, drink water, or use a saliva substitute.

There is no cure for a cold. It will get better on its own - without antibiotics. Antibiotics won't help you get better if you have a cold. When antibiotics aren't needed, they won't help you, and their side effects could still cause harm.

Antibiotics Are Not for Colds and Flu Most infections are caused by two main types of germs - bacteria and viruses. Bacteria are organisms found almost anywhere, except normally sterile sites, such as the blood stream and spinal fluid.

Theraflu is here to help you fight your cold and flu symptoms, including chest congestion, body aches, sore throat, cough and sinus and nasal congestion.

The problem with too much acetaminophen Acetaminophen is primarily processed in the liver. The liver breaks down most of the acetaminophen in a normal dose and eliminates it in the urine. But a small portion of the drug is converted to a byproduct that is toxic to the liver cells.
