Here is a complete dosing summary for glycerol (glycerin) across its main clinical uses:

Glycerol (Glycerin) - Dosing by Indication

1. Osmotic Laxative (Rectal Use Only)

Glycerin acts rectally as a hygroscopic agent and lubricant - it draws water into the rectum and stimulates peristalsis. Onset is typically 15-30 minutes.

Patient Group	Rectal Enema (solution)	Suppository
Neonate	0.5 mL/kg/dose PR once daily PRN	Sliver/chip of infant suppository
Child < 6 years	2-5 mL PR once daily PRN	1 infant/pediatric suppository (1-1.2 g)
Child ≥ 6 years & Adults	5-15 mL PR once daily PRN	1 adult suppository (2-3 g)

Insert suppository high into rectum and retain for 15 min
May cause rectal irritation, abdominal pain, bloating, dizziness
Goodman & Gilman's Pharmacological Basis of Therapeutics, p. 1113; Harriet Lane Handbook, p. 1165

2. Reduction of Intraocular Pressure / Pre-Op Glaucoma (Oral)

Use	Dose
Reduce IOP (glaucoma/pre-op)	1-2 g/kg orally, given 60-90 minutes before surgery
Osmotic diuretic	1-2 g/kg PO, 1-1.5 hours before surgery

Typically given as a 50% oral solution (Osmoglyn)
Works by increasing plasma osmotic pressure, drawing fluid out of the eye

3. Reduction of Corneal Edema (Ophthalmic)

1-2 drops of ophthalmic glycerin solution topically before eye exam
Or 1-2 drops every 3-4 hours for corneal edema management

4. Reduce Intracranial Pressure (IV/oral - specialist use)

Oral: 1-1.5 g/kg given every 4-6 hours
IV: administered under specialist supervision (risk of hemolysis with IV route)
Used in: stroke, meningitis, encephalitis, Reye's syndrome, neurosurgical procedures

5. Dry Cough / Sore Throat Syrup (e.g., Glycerin 0.75 g/5 mL oral syrup)

Age	Dose	Frequency
Adults & children > 12 yr	5-10 mL (1-2 teaspoonfuls)	Up to 4 times daily
Children 6-12 yr	5 mL (1 teaspoonful)	Up to 4 times daily
Children 1-5 yr	2.5 mL (half teaspoonful)	Up to 4 times daily
Under 1 year	Not recommended	-

Key Precautions

Oral glycerol can cause headache, nausea, vomiting, bloating, thirst, and diarrhea
IV glycerol risks serious red blood cell damage - avoid unless specialist-directed
Elderly patients are at increased risk of dehydration and electrolyte disturbance
Children are at higher risk for side effects from oral glycerol
Avoid in cardiac failure, renal or hepatic impairment - use with caution

Ose in ml for 50 kg fenale

Based on your previous question about glycerol syrup, I'll calculate the dose for a 50 kg female across the relevant indications.

Glycerol Dose for a 50 kg Female

1. Reduce Intraocular Pressure / Pre-op (Oral 50% solution)

Dose: 1–2 g/kg
For 50 kg: 50–100 g of glycerol
As 50% solution (0.6 g/mL): 83–167 mL
Typical single dose used: ~1.5 g/kg = 75 g = 125 mL of 50% solution
Give 60–90 minutes before surgery/procedure

2. Reduce Intracranial Pressure (Oral)

Dose: 1–1.5 g/kg
For 50 kg: 50–75 g glycerol
As 50% solution: 83–125 mL
Repeat every 4–6 hours as needed

3. Rectal Enema (Laxative)

Fixed adult dose (not weight-based): 5–15 mL rectal solution once daily PRN
Or 1 adult suppository (2–3 g) PR once daily PRN

4. Dry Cough Syrup (0.75 g/5 mL)

Fixed adult dose (not weight-based): 5–10 mL up to 4 times daily

Summary Table

Indication	Dose (g)	Volume (50% oral solution)
IOP reduction (1 g/kg)	50 g	83 mL
IOP reduction (1.5 g/kg)	75 g	125 mL
IOP reduction (2 g/kg)	100 g	167 mL
ICP reduction (1 g/kg)	50 g	83 mL
ICP reduction (1.5 g/kg)	75 g	125 mL

Note: The 50% oral solution = 0.6 g/mL (or the 75% solution = 0.94 g/mL). Volume will differ depending on the concentration available. Always confirm the concentration on the bottle before calculating.
