Contraceptive injection - 1 Month and 3 Month Types

Contraceptive injection

Contraceptive injection is a convenient, safe, and highly effective method of contraception. With just one injection, it can immediately help prevent pregnancy, sparing you the worry of forgetting to take contraceptive pills or needing protection every time you have sex.

Contraceptive injection comes in two types. The 1 month option (with combined hormones) and the 3 month option (with a single hormone). If you need to use birth control continuously for several months, you can return to get another injection whenever you want.

Contraceptive injection

Contraceptive injection is another popular method of contraception because it's convenient, fast, and eliminates the worry of forgetting to take contraceptive pills. It's highly effective in preventing pregnancy by inhibiting ovulation, which prevents the release of an egg. Additionally, it thickens the cervical mucus, making it difficult for sperm to reach the uterus, and alters the uterine lining, making it less suitable for egg implantation. Moreover, it makes the cervical mucus too thick for sperm to swim through, further enhancing its effectiveness.


Contraceptive injection can only control birth for a short period,
typically 1 or 3 months.
If you don't receive contraceptive injections consistently, there's also a chance of getting pregnant.

The price of injectable birth control ranges from 399 baht to 915 baht. This price does not include pregnancy testing. The cost depends on the type of injectable contraception and the frequency of injections.
