Salonpas Pain Relief Patches Salonpas Pain Relief Patches are medicated patches that relieve muscle & joint pain associated with strains, sprains, back-ache & bruises in adults over 18 years of age. Salonpas Pain Relief Patches use a Transdermal Drug Delivery System (TDDS) which delivers the active ingredients directly to the site of the pain where it's needed. Each patch can be worn for 8-12 hours, day or night, for clinically proven long-lasting pain relief. They are stretchable & flexible, allowing them to stick firmly to any part of the body & are ultra-thin, making them very discreet. Salonpas Pain Relief Patches make a great alternative to pain relief tablets & capsules as the medicine is delivered through the skin, bypassing the stomach. Unlike other patches, Salonpas is actually a medicine, not just a device that warms up your aching body part. Pain relief generally occurs within one hour of application, but in some individuals pain relief may be shorter or longer. Some individuals may not experience pain relief until several hours after applying. Each patch is 7cm x 10cm & can be cut to size if required.
