What is L484 white pill Used For?

L484 is NOT an anti-inflammatory, so it’s not a replacement for ibuprofen or naproxen in all cases.

How Acetaminophen Works

Acetaminophen works by blocking COX enzymes in the brain (but not the rest of the body). This:

• Reduces the sensation of pain

• Lowers fever via the hypothalamus

• Does not reduce swelling or inflammation

It is gentler on the stomach than NSAIDs (like ibuprofen), making it suitable for people with ulcers or acid reflux.

Dosage Guidelines for L484 white pill

Never take more than 4000 mg in 24 hours.
Avoid doubling doses if you miss one.
