Semaglutide is vented with each use.
Semaglutide is usually given by subcutaneous injection, which involves injecting the medicine into the tissues under the skin. Common injection sites are the upper arm and outer femur. If insulin is taken orally in the gastrointestinal tract, it is easily destroyed by digestive enzymes and loses its effect, whereas it can be rapidly absorbed when injected under the skin.
The subcutaneous tissue is loose, even if the air enters into the subcutaneous, it does not matter much, but if the subcutaneous injection is accidentally tied into the vein, it is easy to cause air embolism.
Therefore, the air in the syringe should be emptied before injecting subcutaneously. At the same time, it should be withdrawn before injection. If there is no blood, it indicates that the vein has not been injected and the injection can continue. If air is accidentally injected into the vein, one should go to the hospital promptly to avoid more serious consequences. Specific operations should be carried out under the guidance of a doctor.
