Nessel Hal Allergy (Urtica Dioica)

• Nessel Hal Allergy is used as a topical antiallergic agent to manage nasal and respiratory symptoms caused by allergic inflammation.
• Allergic rhinitis: reduces nasal congestion, sneezing and itching caused by pollen or indoor allergens.
• Seasonal allergic rhinitis: alleviates intermittent symptoms during high pollen periods.
• Hay fever: provides relief from upper airway irritation and watery discharge associated with hay fever.
• Allergic conjunctivitis: helps decrease eye itching and tearing when applied near the ocular area.

• Urtica dioica leaf extract contains flavonoids, phenolic acids and lectins that exhibit anti‑inflammatory and antihistaminic properties. The constituents are thought to stabilize mast cells, inhibit histamine release, and down‑regulate pro‑inflammatory cytokines such as IL‑4 and TNF‑α. By limiting these pathways, the topical preparation reduces the local allergic response in the nasal mucosa and surrounding skin, leading to decreased congestion, itching and sneezing.

Topical application of Nessel Hal Allergy may be associated with local skin reactions and, rarely, systemic allergic events.

Common Side Effects

• Mild skin irritation: transient redness at the application site.
• Itching: localized pruritus following application.
• Dryness: temporary dryness of the treated skin.
• Mild rash: small erythematous patches.

Serious or Rare Side Effects

• Allergic contact dermatitis: intense redness, swelling and blistering requiring medical attention.
• Anaphylaxis: rare systemic hypersensitivity reaction with difficulty breathing or hypotension.
• Severe skin ulceration: deep lesions at the site of application.

When using Nessel Hal Allergy, consider the following precautions to ensure safe and effective use.

• Pregnancy: safety has not been established; consult a healthcare professional before use.
• Breastfeeding: limited data available; use only if benefits outweigh potential risks.
• Pediatric use: suitability for children under 2 years not determined; follow prescriber guidance.
• Concurrent antihistamines: monitor for additive antihistaminic effects and possible skin dryness.

• Store below 25°C: keep in the original packaging, protect from moisture and direct sunlight.

Nessel Hal Allergy may interact with certain medications and herbal products; be aware of the following.

Major Interactions (Avoid)

• Concurrent use with other topical antihistamines: risk of excessive histamine blockade and skin irritation.
• Combination with systemic corticosteroids: may mask worsening allergy symptoms.
• Use with immunosuppressive agents: potential alteration of immune response.

Moderate Interactions (Monitor Closely)

• Co‑administration with oral antihistamines: monitor for additive sedation or dryness.
• Use with non‑steroidal anti‑inflammatory drugs (NSAIDs): may increase risk of localized skin irritation.
• Concurrent use with other herbal extracts (e.g., chamomile, echinacea): observe for enhanced allergic reactions.
