How long does the plaster usually last?

Generally speaking, the plaster should be changed once a day, and some even have to be changed once a half day, depending on the duration of the efficacy in the instructions. The interval between dressing changes should be shortened, preferably 5-6 hours. Between two applications, the affected area should be properly cleaned to remove the drug scale attached to the skin surface, and then the skin should rest for 1~2 hours.

Attention should be paid to when sticking black plaster:

1. Wipe the local area with hot towel or ginger before sticking, then heat the plaster with low fire and apply it to the affected area. ?

2, local redness should not be posted. If skin allergy occurs after sticking, such as itching or redness, you can uncover the plaster and stick it again two or three days later. If the reaction is serious, it should be stopped. A plaster can be used continuously 1-2 weeks before it is removed. ?

3, pregnant women should not stick navel, waist and abdomen. ?

4. Avoid eating cold food during plastering (if instructed). ?

5. If the local area has collapsed or not, and the pain is not limited, you can stick a poisonous plaster, and the usage is the same as that of the black plaster.
