What is L484 Pill Used for?

The l484 pill is a white oblong tablet known as acetaminophen 500 mg, ibuprofen, or paracetamol.

It is an analgesic (pain relievers) and antipyretics (fever reducers) drug used for treating fever and pain from different conditions.

Acetaminophen capsule works perfectly to relieve pain from menstruation, headaches, back pain, arthritis, muscle aches, fever, and many other symptoms. (1)

However, its massive overdose can lead to chemical-driven liver damage known as hepatotoxicity.

According to the New England Journal of Medicine, acetaminophen overdose can cause liver injury.

In their study on 71 patients with acetaminophen overdose, 50 of them took the overdose for a suicidal mission, while the remaining 21 patients took it for quick pain relief.

Although the 50 patients on a suicidal mission took a higher dose of the pills with l484 imprint, the remaining 21 patients had higher death and injury because they had a higher frequency of chronic alcohol abuse.

The study linked alcohol abuse to a greater risk of liver damage.

Acetaminophen during pregnancy and breastfeeding

Pregnant and breastfeeding mothers often use paracetamol for pain and fever relief.

The medication is considered safe during this vital period.

However, recent studies have linked prolonged use of the medication to impairment of neurological development, attention deficit hyperactivity disorder (ADHD), and autistic spectrum disorder (ASD).

The study, which kept a follow-up record of over 100,000 pregnant women for 3 to 11 years, found that

  • Acetaminophen injection crosses the human placental barrier and such is associated with neurodevelopmental impairment in humans.
  • It also discovered a 30% increased risk of ADHD and a 20% increased risk of ASD on exposure to the l484 pills.

It, therefore, recommends short-term use of painkillers during breastfeeding and pregnancy since prolonging the use of it (28 days and above) comes with serious side effects. (4)

Acetaminophen and alcohol

High consumption of alcohol while on Tylenol medication increases the risk of liver toxicity.

This is because the liver converts more of the paracetamol into toxic byproducts.

Men should avoid taking more than 2 bottles, while women take 1 bottle per day when taking l484 medicine, to avoid complications.

This pill should not be for someone allergic to paracetamol, or someone suffering from asthma, bleeding disorder.

Care should be taken when giving medication to pregnant and breastfeeding mothers to avoid complications.

You should store the drug in a tight container, at room temperature.
