MgSO4 Paste (Morison's Paste / Magnesium Sulfate Paste) - Indications
MgSO4 paste is a hypertonic drawing agent used topically. Its osmotic action draws fluid and pus out of infected tissues. Here are all the conditions it is used for:
Primary / Classical Indications
| Condition | Purpose |
|---|---|
| Boils (Furuncles) | Draws pus to the surface, brings the boil to a "head" for drainage |
| Carbuncles | Collection of boils - promotes drainage of pus from multiple follicles |
| Whitlow (Paronychia) | Draws infection from around the nail fold |
| Felons | Pulp space infection of the finger |
| Splinters / Foreign bodies | Helps "draw out" embedded splinters from the skin |
| Abscesses (small/superficial) | Promotes localization and pointing of pus |
Surgical / Clinical Uses
- Post-operative wounds - applied to superficially infected surgical wounds to reduce edema and draw out exudate
- Infected wounds with cellulitis - reduces local swelling via osmotic effect
- Pilonidal sinus - sometimes used as an adjunct after incision and drainage
- Lymphangitis - reduces local tissue edema
- Infected ingrown toenails - draws infection, reduces periungual swelling
Mechanism of Action
MgSO4 is hypertonic - it creates an osmotic gradient that:
- Draws fluid/lymph from deeper tissues to the surface
- Reduces local edema and inflammation
- Softens the overlying skin, facilitating spontaneous drainage
Composition of Standard Paste (BP formula)
- Dried Magnesium Sulfate: 47.8%
- Glycerol: 50.4%
- Phenol (as preservative): 0.4%
- Sometimes with thymol
Important Contraindications
- NOT to be applied on broken/open skin or large wounds
- Avoid on eyes or mucous membranes
- Do not use over large surface areas (risk of systemic absorption)
In surgical practice, MgSO4 paste is most commonly remembered for treatment of boils, carbuncles, and infected wounds - it is a time-tested first-aid and outpatient remedy used before or instead of formal incision and drainage for early/pointing abscesses.
What are the diseases
Asking for Preferences
Here is a focused list of diseases/conditions treated by MgSO4 paste:
Skin & Soft Tissue Infections
1. Furuncle (Boil)
- A deep infection of a hair follicle, usually caused by Staphylococcus aureus
- MgSO4 paste draws pus to the surface and helps the boil "point" for drainage
2. Carbuncle
- A cluster of interconnected furuncles forming a multi-headed abscess
- Common on the back of neck, shoulders, thighs
- Paste helps localize and drain the infection
3. Abscess
- A localized collection of pus in any tissue
- Paste promotes pointing and spontaneous drainage of superficial abscesses
4. Paronychia (Whitlow)
- Infection of the nail fold (acute paronychia)
- Paste reduces swelling and draws out pus around the nail
5. Felon
- Pulp space infection of the fingertip
- Used as adjunct to reduce swelling before surgical drainage
6. Infected Wound / Cellulitis
- Wounds with surrounding induration and edema
- Osmotic action reduces swelling and draws out exudate
7. Infected Ingrown Toenail (Onychocryptosis)
- Reduces periungual inflammation and infection
8. Pilonidal Sinus / Abscess
- Used post-drainage to aid wound healing
Non-Infectious / Other Uses
9. Splinter / Embedded Foreign Body
- Softens skin and draws the splinter toward the surface
10. Pimples / Cystic Acne (off-label)
- Used on closed comedones with pus to draw out contents
Key Point for Exams
MgSO4 paste = treatment of boils and carbuncles is the most tested fact. The hypertonic glycerin-magnesium sulfate combination creates an osmotic gradient that reduces edema and promotes drainage of pus-forming infections.
