Mechanism of Action (MOA)

Zinc oxide acts as a physical barrier that protects the skin from irritants such as moisture, urine, and feces. It provides astringent, antiseptic, and mild anti-inflammatory effects by forming an occlusive layer over the skin that reduces transepidermal water loss and friction. It also has mild antimicrobial activity, promoting an environment that supports skin healing and prevents further breakdown.

Pharmacokinetics

Absorption:

  • Minimal to no systemic absorption when applied topically to intact or mildly inflamed skin.
  • Increased absorption possible if applied over large areas of broken skin, open wounds, or mucous membranes.

Distribution, Metabolism, Excretion:

  • Not systemically distributed or metabolized under normal conditions.
  • Excretion data not relevant due to lack of systemic absorption.
Pregnancy Category & Lactation

Pregnancy:

  • Generally recognized as safe (GRAS) for topical use in pregnancy. No known teratogenic effects.
  • Minimal to no systemic absorption.

Lactation:

  • Safe during breastfeeding when used as directed.
  • Avoid application to the breast or nipple area unless under physician guidance.
Therapeutic Class
  • Primary: Skin Protectant
  • Subclass: Topical barrier agent / Inorganic compound (zinc derivative)
Contraindications
  • Hypersensitivity to zinc oxide or any formulation components
  • Application to deep puncture wounds or serious burns unless directed by a physician
  • Avoid use on infected or oozing lesions without medical supervision
Warnings & Precautions
  • For external use only – avoid contact with eyes and mucous membranes.
  • Discontinue if irritation, rash, or allergic reaction occurs.
  • Not a treatment for fungal or bacterial infections – avoid misuse on infected areas.
  • If symptoms worsen or persist >7 days, consult a physician.
  • Do not use on large, raw, or blistered skin without medical advice.
Side Effects

Common (rare in appropriate use):

  • Mild stinging or itching at the application site
  • Skin whitening (due to zinc oxide paste)

Rare/Serious Reactions:

  • Allergic contact dermatitis
  • Local irritation with prolonged or excessive use
  • Worsening of underlying skin infection if misused

Timing & Dose-Dependence:

  • Reactions typically mild and localized; more likely with broken skin or long-term use without cleansing.
Drug Interactions
  • No known significant systemic drug interactions due to minimal absorption.
  • Topical interaction potential:
    • May reduce absorption of other topicals if layered (e.g., corticosteroids or antimicrobials) — apply separately and allow sufficient drying time.
  • No CYP enzyme involvement.
Recent Updates or Guidelines
  • FDA labeling reaffirmed that zinc oxide is a Category I active ingredient (safe and effective) in over-the-counter skin protectant drug products for diaper rash.
  • AAP and pediatric dermatology guidelines continue to support barrier creams containing zinc oxide as first-line therapy and prevention for irritant diaper dermatitis.
  • Updated formulations now include fragrance-free and hypoallergenic options to minimize sensitivity risk in neonates.
Storage Conditions
  • Store at 15–30°C (59–86°F)
  • Protect from excessive heat, light, and moisture
  • Do not freeze
  • Tightly close container after use to prevent drying
  • No shaking, mixing, or reconstitution needed
