I now have all the information needed to calculate the dose. Here's the full answer:

Paracetamol (Pacimol) Dosing for a 5-Month-Old, 7 kg Infant

Step 1 — Calculate the Dose

The standard paracetamol dose for fever in infants is 10–15 mg/kg/dose, given every 4–6 hours. Do not exceed 5 doses in 24 hours.
Calculation
Low end (10 mg/kg)10 × 7 = 70 mg/dose
High end (15 mg/kg)15 × 7 = 105 mg/dose
The Harriet Lane Handbook dosing table for an infant weighing 5.1–7.7 kg (4–11 months) gives a recommended dose of 80 mg per dose — this falls within the 10–15 mg/kg range and is the standard reference dose for this weight band.

Step 2 — Calculate the Volume from Pacimol 15 mg/5 mL Syrup

Pacimol pediatric syrup is available as 15 mg / 5 mL (3 mg/mL).
DoseVolume needed
70 mg70 ÷ 3 = ~23.3 mL
80 mg (standard ref dose)80 ÷ 3 = ~26.7 mL
105 mg105 ÷ 3 = 35 mL
⚠️ Important note: Pacimol 15 mg/5 mL is a very low-concentration formulation. For a 7 kg infant, even the minimum dose (~70 mg) requires over 23 mL in one sitting, which is a large volume for a 5-month-old. This formulation is more commonly intended for neonates/small infants in specific clinical settings.

Recommended Action

The more practical formulation for home/outpatient use is:
  • Pacimol syrup 125 mg/5 mL (25 mg/mL) → dose would be 2.8–4.2 mL (much more practical)
Please verify which Pacimol formulation you actually have:
  • Pacimol 15 mg/5 mL → need ~23–27 mL per dose (unusually large volume — double-check the label)
  • Pacimol 125 mg/5 mL → need ~2.8–4.2 mL per dose (standard)
If the bottle truly reads 15 mg/5 mL, give approximately 26–27 mL per dose, but this is an atypical formulation and you should confirm with a pharmacist or prescribing physician.

Summary (if bottle is confirmed 15 mg/5 mL):
  • Dose: 80 mg (standard for 7 kg infant, 4–11 months)
  • Volume: ~26–27 mL per dose
  • Frequency: Every 4–6 hours, max 5 doses in 24 hours
  • Max daily dose: 75 mg/kg/day = 525 mg/day

This is the pacimol i have

This is Pacimol Drops — Acetaminophen (Paracetamol) Oral Suspension USP 100 mg/mL. This is the concentrated infant drops formulation, much stronger than regular syrup.

Dose Calculation for Your Infant

Weight7 kg
Age5 months
FormulationPacimol Drops 100 mg/mL
Standard dose10–15 mg/kg/dose
Dose needed:
  • Low end: 10 × 7 = 70 mg
  • Standard: 15 × 7 = 105 mg
  • Recommended: ~70–105 mg per dose
Volume to give:
Since concentration = 100 mg/mL: Volume = Dose ÷ 100
DoseVolume
70 mg0.7 mL
80 mg (typical for 7 kg)0.8 mL
105 mg1.05 mL

✅ Give: 0.7 mL to 1.0 mL per dose

  • Use the dropper that comes with the bottle
  • Give every 4–6 hours as needed for fever
  • Do not exceed 5 doses in 24 hours
  • Maximum daily dose: 75 mg/kg/day = 525 mg/day for this infant

⚠️ Note: This is a high-concentration drops formulation (100 mg/mL). Be careful not to confuse it with regular syrup (125 mg/5 mL). Always use only the dropper provided — never a household spoon. If fever persists beyond 2–3 days or the infant appears very unwell, consult a doctor promptly.
