External use only. Avoid contact with eyes, mouth and mucous membranes. Do not use on cuts, wounds, eczema or infected skin. Stop use and seek medical advice if severe irritation/allergic reaction occurs. Use with caution in children, elderly, glaucoma, prostate enlargement or urinary retention as systemic absorption of belladonna alkaloids (rare) may cause anticholinergic effects (dry mouth, blurred vision, dizziness, fast heartbeat). Do not use with heating pads or occlusive dressings unless advised. If pain persists beyond a few days or is associated with swelling/fever, consult a doctor.
