Effective for 3-5 years

Convenient and worry-free
An additional benefit of having contraceptive implants is that it is quick, easy, and safe birth control option. There is no recovery period, and you don’t have to worry about forgetting to take contraceptive pills on time each day or getting injections that need monthly doctor appointments.

Fertility returns faster compared to injectable contraceptives
Did you know that you can conceive 90% faster with a contraceptive implant than with an injection?

Because the contraceptive implant eliminates the need for waiting, unlike other birth control methods, it appeals to women who wish to become parents immediately
No effect on breast milk quality and quantity
Breastfeeding women can use contraceptive implants because the medications in implants do not affect the amount of milk secretion and the nutrients in breast milk.

Some people cannot use contraceptive pills because they contain estrogen, which can affect their body and overall lifestyle. As a result, those who are unable to take estrogen-containing contraceptive pills can benefit from contraceptive implants. However, it depends on the doctor’s advice on which method of birth control to use.

The insertion and removal of contraceptive implants must be performed by a gynecologist (or a specialist physician in the event of a general practitioner).
However, as insertion of a contraceptive implant is regarded as a minor procedure, the majority of interns overlook and have never been trained in this procedure.
“There are comparatively few doctors who specialize in contraceptive implants because some doctors may have little to no experience in insertion of contraceptive implants.”
Side effects vary from person to person
One disadvantage of contraceptive implants is that some people may experience side effects, such as irregular periods (extremely frequent periods, irregular periods, or in some cases, missing periods for several months).
Other potential side effects include bruising, blood spots, scarring on the forearm, wound inflammation in the implant location, and unusual pain in the arm where the implant is put for some people.
Return to Cons of contraceptive implants

Lack of expertise among doctors who perform contraceptive implant insertion
The effectiveness of contraception may be diminished if the doctor who insert the contraceptive implants lacks experience or is not sufficiently skilled. For example, the contraceptive implants could be implanted in the incorrect position or too shallow, which could cause pain and swelling and make the implant wound more susceptible to infection and inflammation. “Improper insertion of contraceptive implants damages nerves and blood vessels.”

Forgetting the removal date
Since contraceptive implants last for three or five years, some people forget to remove them, which may lead to strong adhesion between implants and tissue beneath their forearm. In this situation, surgery is necessary, and removal of the implant would cost two or three times higher.
Contraceptive implants may not be suitable for everyone
It’s true that the majority of women opt for contraceptive implants as their method of birth control in order to avoid unintended pregnancy. However, not everyone is a good candidate for contraceptive implants, particularly if the patient has serious health issues.
-
People who are at risk or have blood clots in their blood vessels, including people with blood clotting disorders and people who take anticoagulants.
-
People with a history of heart disease or cerebrovascular disease
-
People who experience inexplicable vaginal or other organ bleeding.
-
People with liver disease, impaired liver function, hepatitis, liver tumors or cancer.
-
People who are undergoing treatment for chronic diseases and need to take medication to treat the disease, which may reduce the effectiveness of birth control pills, such as medications for AIDS patients, medications for epilepsy, certain types of antibiotics, etc.
-
For some people who experience other health issues after contraceptive implant insertion, such as depression, high blood pressure, headaches or migraines, coronary artery disease, etc, the doctor will recommend removing the implant early.
Due to its high effectiveness, most women opt to use them as a temporary method of contraception to avoid unintended pregnancies. It enables up to five years of pregnancy prevention with the easy insertion procedure.
It’s important to note that contraceptive implants have certain benefits, drawbacks, or restrictions. In order to select the most suitable and safe option of birth control, users should research the specifics on their own or see a medical professional.
