3. How to Use Larin
Typical Adult Dosing (1‑gram tablets)
| Dose | Frequency | Max Daily Dose |
|------|-----------|----------------|
| 1 tablet (1 g) | Every 4–6 h as needed | 4 g (max) |
| Alternate (if you have 500 mg tablets) | 2 tablets (1 g) every 4–6 h | 4 g |
- Do not exceed 4 g in 24 h (or 8 g if you’re on a 12‑h schedule and your doctor has specifically advised it—rare).
- For a 30‑day supply of 1‑g tablets: 5 tablets per pack, 30 packs = 150 tablets.
- Take with food or a full glass of water to reduce stomach upset (though paracetamol is generally gentle on the stomach).
Children (Age & Weight)
| Age | Weight | Dose (per kg) | Frequency |
|-----|--------|---------------|-----------|
| 2–4 y | 10–14 kg | 10 mg/kg | Every 4–6 h |
| 4–8 y | 14–23 kg | 10–15 mg/kg | Every 4–6 h |
| 8–12 y | 23–35 kg | 15 mg/kg | Every 4–6 h |
| 12 y+ (adolescents) | 35+ kg | 15 mg/kg | Every 4–6 h |
Tip: For children, the 500 mg tablets are typically easier to dose than 1‑g tablets. Use a pediatric dosing device (oral syringe, medicine cup) or a kitchen scale for accuracy if you’re measuring liquid forms.
Special Populations
| Group | Notes |
|-------|-------|
| Pregnancy | Category B. Use only if benefits outweigh risks; consult your OB. |
| Breastfeeding | Generally safe. The amount that passes into breast milk is minimal, but monitor the infant for any rash or upset stomach. |
| Liver disease | Avoid; paracetamol is metabolised in the liver. |
| Renal impairment | Usually safe, but check with a clinician if severe kidney disease. |
| Alcohol users | Heavy drinking increases risk of liver damage. Avoid or limit alcohol while taking Larin. |

| Concurrent use of other hepatotoxic drugs (e.g., certain anti‑epileptics). |

6. Drug Interactions
| Drug/Agent | Interaction |
|------------|-------------|
| Warfarin | Minor; monitor INR if on chronic warfarin therapy. |
| Other NSAIDs (ibuprofen, naproxen, aspirin) | Additive GI irritation risk (paracetamol is safer, but avoid unnecessary combinations). |
| Alcohol | Increases hepatic load; avoid or limit. |
| Certain anti‑epileptics (e.g., phenytoin) | May increase paracetamol metabolism; monitor liver enzymes. |
| Caffeine | Mildly increases the perceived pain‑relieving effect; not a major concern. |
