In fact, any intramuscular injections, including buttock injections, can be showered 2 hours after the injection, because after 2 hours, the wound at the injection site has closed and there is no risk of bacterial infection, as well as the injected medication does not flow out and can basically be absorbed to a certain extent. The water temperature should not be too high when bathing, do not repeatedly wash the site of your injection eye, and do not use too much shower gel, soap or soap to avoid affecting the absorption of the medicine.
