Encountering an unidentified pill can be concerning. Accurate identification is essential for personal safety, helping prevent potential health risks.
Understanding the Imprint Code
A white, capsule-shaped or oblong pill marked with the imprint “L484” is Acetaminophen 500 mg. This common over-the-counter medication relieves pain and reduces fever. Imprint codes like “L484” are unique identifiers used by drug manufacturers to specify the active ingredient, strength, and sometimes the manufacturer. These codes help pharmacists, healthcare providers, and consumers quickly identify and verify a pill’s contents and origin.
Uses of This Medication
Acetaminophen 500 mg alleviates mild to moderate pain and reduces fever. It acts as an analgesic, relieving pain, and an antipyretic, lowering body temperature. This medication treats conditions such as headaches, muscular aches, minor arthritis pain, toothaches, backaches, and discomfort from colds and fevers.
Safe Administration and Important Warnings
Proper administration of Acetaminophen 500 mg is important to avoid adverse effects. Adults and teenagers typically take 650 to 1000 milligrams every 4 to 6 hours as needed. The maximum daily dose for adults should not exceed 4,000 milligrams (4 grams) in a 24-hour period. Exceeding this limit can lead to severe liver damage. Always read product labels and avoid taking multiple medications containing acetaminophen simultaneously to prevent overdose.
Common side effects include nausea, stomach pain, or headache. More serious side effects can occur, such as severe skin reactions (reddening, blisters, or rash) and allergic reactions (swelling of the face, throat, or tongue), which require immediate medical attention. Alcohol consumption while taking acetaminophen increases the risk of liver damage. Individuals who consume three or more alcoholic drinks daily should consult a healthcare professional before using this medication. Acetaminophen can also interact with other medications, including blood thinners like warfarin, and certain seizure medications.
When to Seek Professional Guidance
Consult a healthcare professional if pain persists for more than 10 days or if a fever lasts for more than 3 days. Seek medical advice if symptoms worsen or if new or unexpected symptoms appear, such as redness or swelling. Signs of a serious allergic reaction, including hives, difficulty breathing, or swelling of the face, lips, or throat, require immediate emergency medical attention. Symptoms that may indicate liver problems, such as unusual tiredness, yellowing of the skin or eyes (jaundice), dark urine, or upper right abdominal pain, also warrant prompt medical evaluation. Individuals with a history of liver disease or those taking other medications should always consult a doctor or pharmacist before starting acetaminophen to ensure safe use and prevent potential interactions.
