Lhp (Hydrogen Peroxide)

Lhp is a topical antiseptic that acts on the skin and superficial wounds to provide rapid antimicrobial action.

• Skin antisepsis: reduces microbial load on intact skin before procedures.
• Wound cleaning: helps disinfect minor cuts, abrasions and superficial wounds.
• Pre‑operative preparation: provides rapid antiseptic action on surgical sites.

• Hydrogen peroxide acts as an oxidizing agent that releases nascent oxygen upon contact with tissue. The liberated oxygen generates free radicals that damage microbial cell walls, oxidize proteins and nucleic acids, and disrupt essential metabolic pathways, resulting in rapid microbial death and antiseptic activity on the skin surface.

Adverse reactions are generally limited to the application site and may vary in severity.

Common Side Effects

• Mild skin irritation: transient redness or discomfort.
• Burning sensation: brief stinging upon application.
• Erythema: localized redness.
• Itching: occasional pruritus.
• Dryness: temporary loss of skin moisture.
• Contact dermatitis: mild allergic skin response.

Serious or Rare Side Effects

• Severe allergic reaction: anaphylaxis or angioedema.
• Chemical burns: deep tissue injury with prolonged exposure.
• Tissue necrosis: rare extensive cell death.
• Ocular injury: severe eye damage if splashed.
• Systemic toxicity: unlikely but possible with large surface area exposure.
• Persistent ulceration: prolonged ulcer formation at the site.

When using Lhp, follow these safety measures to minimize risk.

• Avoid deep or puncture wounds: limit use to superficial lesions.
• Do not apply to mucous membranes: eyes, ears, nose, or genital areas.
• Keep away from eyes: immediate irrigation if contact occurs.
• Do not use on compromised skin: such as burns or extensive dermatitis.
• Do not mix with other chemicals: avoid combining with organic solvents or reducing agents.
• Store at room temperature: keep in original container, protect from moisture and direct sunlight.

Hydrogen peroxide may interact with certain substances; consider the following.

Major Interactions (Avoid)

• Organic solvents (e.g., acetone, ethanol): can cause rapid decomposition.
• Reducing agents (e.g., ascorbic acid): neutralize antiseptic activity.
• Strong acids or bases: may lead to uncontrolled release of oxygen.
• Metal ions (e.g., copper, iron): catalyze decomposition and reduce efficacy.
• Silver‑containing dressings: can inactivate both agents.

Moderate Interactions (Monitor Closely)

• Concurrent topical antiseptics: may increase irritation.
• Antibiotic ointments: monitor for combined skin reactions.
• Wound dressings with absorbents: assess for altered release profile.
• Antioxidant‑rich creams: may diminish oxidative effect.
• Systemic antioxidants: unlikely but note potential reduced local activity.
