Kamistad N (Chamomile Flowers Fe With Ethanol-Water Trometamol, Lidocaine Hydrochloride)

Kamistad N is a combination topical preparation used to alleviate discomfort associated with superficial skin conditions.

• Minor skin irritation: soothes redness and itching while providing local pain relief.
• Superficial burns (first‑degree): reduces pain and supports comfort during healing.
• Insect bites and stings: diminishes swelling, itching, and localized pain.
• Small abrasions or cuts: offers anesthetic effect and calming of irritated skin.

• Chamomile Flowers contain flavonoids and essential oils that inhibit inflammatory mediators, while Lidocaine Hydrochloride blocks voltage‑gated sodium channels to prevent nerve impulse transmission, producing local anesthesia. Trometamol acts as a buffering agent, maintaining optimal pH for lidocaine stability and skin tolerability, together delivering anti‑inflammatory and analgesic actions at the site of application.

Topical application of Kamistad N may be associated with local skin reactions.

Common Side Effects

• Mild erythema: temporary redness at the application site.
• Itching: occasional pruritus following use.
• Slight burning sensation: brief discomfort that resolves quickly.
• Transient numbness: short‑lasting loss of sensation where applied.
• Local allergic dermatitis: mild rash in sensitive individuals.

Serious or Rare Side Effects

• Severe allergic reaction (anaphylaxis): rapid swelling, breathing difficulty, requires immediate medical attention.
• Contact dermatitis: extensive skin inflammation persisting beyond 24 hours.
• Systemic lidocaine toxicity: rare, manifests as dizziness, tinnitus, or cardiac irregularities.
• Infection at application site: if skin barrier is compromised.
• Persistent numbness: lasting longer than expected, indicating possible over‑absorption.

Before using Kamistad N, consider the following safety measures.

• Allergy assessment: verify no known hypersensitivity to chamomile, lidocaine, or trometamol.
• Skin integrity: avoid application on broken, infected, or severely damaged skin.
• Pediatric use: limit to children over 2 years unless directed by a healthcare professional.
• Concomitant topical anesthetics: do not combine with other numbing agents without medical advice.
• Pregnancy and breastfeeding: consult a physician before use as safety data are limited.
• Store at ambient temperature: keep below 25 °C in the original container, protect from moisture and direct sunlight.

Kamistad N may interact with other substances applied to the skin or absorbed systemically.

Major Interactions (Avoid)

• Concurrent use of other topical anesthetics: risk of additive lidocaine toxicity.
• Systemic antiarrhythmic drugs (e.g., amiodarone): may increase lidocaine plasma levels if absorbed.
• Strong CYP3A4 inhibitors: could alter lidocaine metabolism when systemic absorption occurs.

Moderate Interactions (Monitor Closely)

• Alcohol‑based skin products: may enhance irritation or increase absorption.
• Herbal or cosmetic creams containing essential oils: potential for increased sensitization.
• Occlusive dressings: can raise local drug concentration, requiring monitoring.
