Contraceptive injections for women are injected in the deltoid muscle of the buttocks or arm, the same as ordinary intramuscular injections.
Contraceptive injection for women belongs to the long-acting contraceptive injection, which is injected once a month and must be injected at a fixed time so as to avoid irregular bleeding caused by contraceptive pills.
The main ingredient of long-acting contraceptive injection is hydroxy esterified progesterone, such as progesterone caproate, etc. After intramuscular injection, the drug will be deposited locally, stored, and released slowly so as to exert a long-acting effect.
The advantage of LLIN is that once injected, there is no need to use other contraceptives for a month, and the effect of the drug is long-lasting. The disadvantage is that once there are side effects, they last for a long time. Therefore, before using the long-acting contraceptive injection, use the short-acting contraceptive pill first, and then use the long-acting contraceptive injection if there are no side effects.
If you have no plan to get pregnant and need to take proper contraceptive measures, it is recommended to consult a doctor in obstetrics or reproductive assisted conception to choose a suitable contraceptive method.
