The same instructions apply to adults, children and the elderly. Apply gently across the forehead as required (taking care to avoid the eyes). Do not use too much otherwise the skin sensation may become excessive. If this occurs, subsequent applications should be less frequent or over a smaller area. 4head must only be used on the forehead. Stop using 4head if it feels uncomfortable. If you experience any other undesirable effects, or if your symptoms persist or worsen, seek medical advice. If 4head is accidentally swallowed, seek medical attention, taking this leaflet with you. Keep 4head away from sources of heat or warmth at all times. The levomenthol stick may soften or even melt at high temperatures (e.g. in a car or in the sun on a hot day), leading to a risk of distortion or spillage. Do not attempt to use 4head if the levomenthol stick appears to be distorted, softened or fragmented.
