However, the drug content on the plaster is limited, such as flurbiprofen cataplasm. 12 hours later, the skin has absorbed the effective components of the plaster, even if it is pasted, it has no effect. When removing the plaster and changing the medicine, you should pay attention to cleaning the affected area, keep the skin clean, let the skin "breathe" properly, take a rest, and then put on the next patch.
Extended data:
If the plaster is stuck for a few days, or if it is not cleaned between the two patches, it may induce allergies and even contact dermatitis, and erythema with the same shape and clear boundary as the plaster will appear, accompanied by severe itching and even blisters or even bullae.
In this case, gypsum must be removed immediately. If the symptoms are mild, wash the local area to reduce skin contact and friction, and don't stick a plaster before recovery. If the symptoms are serious, such as blistering or even bursting, you must go to the hospital for treatment. Therefore, the plaster must not be misplaced, and it should not be fixed with adhesive tape to prevent the plaster from falling off, which hinders the ventilation of the affected area and is prone to problems.
