Nicam (Nicotinamide)

Nicotinamide, the active ingredient in Nicam, is a vitamin B3 presented as a topical formulation for skin application. It supports skin barrier function and cellular energy metabolism, and is used in dermatological care and as a nutritional supplement.

GNH USA supplies Nicam as a licensed, GDP-compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Nicam is a topical nicotinamide that acts on skin health and barrier function. It is commonly employed in the following dermatological contexts: - Acne: reduces inflammatory lesions and comedone formation. - Hyperpigmentation: lightens dark spots by inhibiting melanosome transfer. - Photoaging: improves skin texture, reduces fine lines and enhances overall tone.

Topical nicotinamide is generally well tolerated, but adverse reactions can occur.

Common Side Effects: - Mild skin irritation: transient redness or tingling at the application site. - Erythema: slight redness that usually resolves within hours. - Itching: occasional pruritus, especially on sensitive skin. - Dryness: temporary loss of moisture after initial use. - Burning sensation: brief discomfort that diminishes with continued use.

Serious or Rare Side Effects: - Allergic contact dermatitis: swelling, rash, or blistering requiring medical attention. - Severe skin swelling: pronounced edema that may indicate hypersensitivity. - Urticaria: hives or welts appearing after application. - Stevens‑Johnson syndrome: extremely rare, severe mucocutaneous reaction. - Angioedema: rapid swelling of deeper skin layers. - Anaphylaxis: rare systemic allergic response requiring emergency care.

When using Nicam, consider the following safety measures: - Pregnancy: consult a healthcare professional before use. - Breastfeeding: discuss potential risks with a physician. - Skin sensitivity: perform a patch test on a small area before widespread application. - Concurrent topical retinoids: may increase irritation; monitor skin response. - Storage: keep at ambient temperature: store in the original container, protect from moisture and direct sunlight.

Nicotinamide may interact with other topical agents or systemic supplements.

Major Interactions (Avoid): - Concurrent use with topical vitamin C formulations: may increase skin irritation. - Use with photosensitizing agents (e.g., tetracycline): may heighten sun sensitivity.

Moderate Interactions (Monitor Closely): - Co‑application with other moisturizers: may alter nicotinamide absorption. - Systemic nicotinamide supplements: could increase total nicotinamide intake. - Combination with topical corticosteroids: may reduce the efficacy of nicotinamide.
