Get Theraflu Online

Theraflu is formulated to relieve multiple cold and flu symptoms at once, including fever, nasal congestion, runny nose, sneezing, and minor body aches and pains. The three active ingredients each target a different symptom pathway.

Acetaminophen reduces fever and relieves minor pain. Chlorpheniramine is an antihistamine that reduces runny nose and sneezing by blocking histamine receptors. Phenylephrine is a nasal decongestant that narrows blood vessels in the nasal passages to reduce swelling and congestion.

Theraflu may not be appropriate for people with high blood pressure, heart disease, thyroid disease, diabetes, enlarged prostate, or glaucoma. It should also be used cautiously in people taking MAO inhibitors or other medications containing acetaminophen, as exceeding the maximum daily acetaminophen dose can cause liver damage.

You should not take Theraflu alongside other products that contain acetaminophen, antihistamines, or decongestants, as this could lead to double-dosing and increase the risk of side effects. Always review all medications with your physician before starting Theraflu.

Common side effects include drowsiness, dry mouth, dizziness, and mild nausea due to the chlorpheniramine component. Phenylephrine may cause increased heart rate or mild nervousness in some people. Contact your physician if side effects are severe or persistent.

Most people begin to feel relief within 30 to 60 minutes of taking Theraflu. The decongestant and fever-reducing effects typically become noticeable within this window, though individual responses vary depending on symptom severity and overall health.
