Paracetamol (Acetaminophen) Tablet Dosage Calculator
Calculate safe tablet intake for adults and teens. Includes a daily cumulative tracker to prevent accidental overdose and liver toxicity.
About
Acetaminophen (Paracetamol) is one of the most common over-the-counter painkillers, yet it carries a narrow therapeutic index. Exceeding the daily limit (typically 3000 mg or 4000 mg depending on the region) can lead to severe liver damage. This tool assists adults and teenagers in calculating their current intake and planning safe intervals for subsequent doses.
The interface includes a "Daily Cumulative Tracker" that sums up doses taken within a 24-hour window. This is particularly useful when alternating between different tablet strengths (e.g., Regular Strength 325 mg vs. Extra Strength 500 mg) or when managing pain over several days.
Formulas
The calculation is a summation of intake I over a sliding 24-hour window.
Safety Condition:
24h∑t=0 Doset ≤ 4000 mg
If the sum exceeds 4000 mg (or 3000 mg for conservative limits), the system flags a toxicity warning.
