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

Kamistad is applied topically to address pain and inflammation in the skin and superficial tissues.

• Minor skin irritation: provides soothing relief and reduces redness.
• Superficial burns (first-degree): alleviates pain and limits inflammatory response.
• Insect bites and stings: diminishes itching and localized swelling.
• Minor musculoskeletal aches (e.g., sprains): offers temporary analgesia and anti‑inflammatory effect.

• Lidocaine hydrochloride blocks voltage‑gated sodium channels in peripheral nerve membranes, preventing depolarisation and producing local anaesthesia. Chamomile flower extracts contain flavonoids such as apigenin and essential oils that inhibit cyclo‑oxygenase pathways and modulate inflammatory mediators, delivering soothing and anti‑inflammatory activity. The formulation’s ethanol‑water base enhances skin penetration, allowing both components to act efficiently.

Topical application of Kamistad may be associated with local and, rarely, systemic adverse reactions.

Common Side Effects

• Skin irritation: mild redness or itching at the application site.
• Burning sensation: transient warmth or tingling shortly after application.
• Dryness: slight drying of the treated skin area.
• Contact dermatitis: mild allergic skin response.
• Pruritus: increased itching beyond the treated area.
• Erythema: persistent redness lasting more than 24 hours.

Serious or Rare Side Effects

• Allergic reaction: hives, swelling, or difficulty breathing indicating possible anaphylaxis.
• Systemic lidocaine toxicity: dizziness, tinnitus, or cardiac arrhythmia in cases of excessive absorption.
• Severe dermatitis: extensive skin inflammation requiring medical attention.

Before using Kamistad, consider the following precautions to ensure safe and effective application.

• Avoid use on broken or infected skin: may increase systemic absorption and infection risk.
• Do not apply to mucous membranes or eyes: formulation is not intended for these sensitive areas.
• Discontinue if irritation persists beyond 24 hours: seek medical advice if symptoms worsen.
• Use with caution in children and the elderly: skin sensitivity may be higher.
• Check for chamomile allergy before first use: avoid if known hypersensitivity.
• Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Kamistad can interact with certain medications and topical products; awareness of these interactions helps minimise risk.

Major Interactions (Avoid)

• Concurrent use with other lidocaine‑containing topical anesthetics: risk of cumulative systemic lidocaine toxicity.
• Application together with herbal products containing chamomile for patients with known allergy: may trigger severe allergic response.
• Use with other herbal anti‑inflammatory extracts (e.g., arnica) in allergic individuals: increased hypersensitivity risk.
• Combine with systemic lidocaine therapy (e.g., antiarrhythmic drugs): may increase plasma lidocaine levels.

Moderate Interactions (Monitor Closely)

• Systemic lidocaine therapy (e.g., antiarrhythmic drugs): may increase plasma lidocaine levels.
• Use with alcohol‑based skin preparations: can enhance percutaneous absorption, raising local effect.
• Co‑administration with non‑steroidal anti‑inflammatory drugs (NSAIDs): may augment anti‑inflammatory action, monitor for skin irritation.
• Topical corticosteroids applied nearby: may alter skin barrier, affecting absorption.
• Use with other topical analgesics: monitor for additive local effects.
