Oleum Zinci Oxidati Sr Pharmachem (Zinc Oxide)

Zinc oxide, the active ingredient in Oleum Zinci Oxidati Sr Pharmachem, is a physical sunscreen agent presented as a topical preparation for cutaneous use. It provides sun protection and helps prevent sunburn on exposed skin.

GNH USA supplies Oleum Zinci Oxidati Sr Pharmachem as a licensed, GDP-compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Zinc oxide is used as a physical UV filter for skin protection against ultraviolet radiation.

- Sun protection: creates a barrier that reflects and scatters UVA and UVB rays, reducing skin exposure. - Sunburn prevention: lowers the risk of erythema and painful burns after sun exposure. - Dermatological skin protection: shields sensitive or compromised skin (e.g., eczema) from harmful UV radiation.

Zinc oxide is generally well tolerated, but topical application can cause skin reactions in some individuals.

Common Side Effects: - Mild skin irritation: transient redness or itching at the application site. - Dryness: temporary feeling of dry or tight skin. - Stinging sensation: brief discomfort when applied to sensitive areas. - Contact dermatitis: localized rash due to sensitivity.

Serious or Rare Side Effects: - Severe allergic contact dermatitis: extensive rash, swelling, or blistering. - Angioedema: rapid swelling of deeper skin layers, potentially affecting the face. - Systemic hypersensitivity reaction: rare anaphylactic response requiring immediate medical attention.

When using zinc oxide sunscreen, follow these safety measures.

- Avoid application to broken or inflamed skin: may increase irritation. - Keep away from eyes and mucous membranes: rinse thoroughly if contact occurs. - Use as part of a broader sun‑protection strategy: combine with clothing and shade. - Reapply after swimming, sweating, or towel drying: maintains protective film. - Do not ingest: product is for external use only. - Store at ambient temperature: keep in original container, protect from moisture and excessive heat.

Zinc oxide has limited systemic interactions, but certain topical combinations may affect tolerability.

Major Interactions (Avoid): - Concurrent use with other topical irritants (e.g., strong acids, alcohol‑based products): may increase skin irritation. - Application over medicated skin lesions (e.g., corticosteroid‑treated areas) without physician guidance: could alter drug absorption.

Moderate Interactions (Monitor Closely): - Use with other sunscreen agents containing chemical filters: monitor for combined irritation. - Simultaneous use of oral zinc supplements: generally safe but monitor for excessive zinc exposure in sensitive individuals.
