Methods of application

1. Remove the aluminum plastic cap of the penicillin bottle, absorb the sterile water for injection (different specifications of products, the dosage of sterile water is different: 150mg5.0mL,120mg:4.0mL,90mg: 3.0mL, 60mg:2.0mL) by a syringe with a sterile needle, inject the sterile water for injection into the penicillin bottle slowly. After water injection, the mixture is shaken for 1 min and stood for 30-60min to ensure complete dissolution of the lyophilized powder and removal of the bubbles.The penicillin bottle can be gently shaken before injection to evenly disperse the product.

2. After sterilizing the rubber stopper on the mouth of the syringe bottle, draw 1-3 mL of suspension into a sterile disposable syringe using a new sterile needle. Replace the sterile needle with a sterile needle no smaller than 26G, expel a small amount of suspension to eliminate air, and check the needle for clogging.

3. After disinfection of the injection site, the suspension can be injected.

4. Recommended injection method oSingderm:in order to control the injection depth, stretch/pull the skin opposite to the direction of injection to keep the injection surface flat, Using a sterile needle no smaller than 26G, enter the skin at an oblique angle o30"-40°. After reaching to the deep dermis, the needle is advanced at an angle of 10°to 20*In order to avoid the product entering blood vessel, the syringe should be withdrawn first. If blood withdrawn, the needle should be pulled out. Re-operate after replacing the needle.lf no blood withdraw, retrograde injection can be performed, which is pulling out the needle while advancing the syringe piston. After every 3 to 4 points of injection, the filling site should be massaged to evenly distribute the product.

5. Repeat steps 2-4 and inject the remaining product.

6. After treatment, all remaining items for the medical waste must be discarded immediately after use.

7. Postoperative treatment: After injection, ice packs can be used on the filling site (direct contact with the skin should be avoided) to reduce adverse reactions such as swelling and/or pain.
