Subdermal contraceptive implants, often known by the brand name Implanon or Nexplanon, are a popular form of long-acting reversible contraception (LARC). They are small, flexible rods inserted under the skin of the upper arm, releasing hormones that prevent pregnancy. While they offer a convenient and effective method of birth control, it’s important to understand both the benefits and risks associated with this method.
Benefits of Subdermal Contraceptive Implants
Convenience and Effectiveness
One of the primary advantages of subdermal implants is their effectiveness. They are one of the most effective forms of contraception, with a failure rate of less than 1% with typical use. This makes them an excellent choice for individuals who want a reliable method without having to think about it daily.
Long-Acting
Implants can provide protection for up to 3-5 years, depending on the type. This long-acting nature is particularly beneficial for those who want to avoid the need for frequent hormonal adjustments or for those who may forget to take oral contraceptives.
Reduced Risk of Pregnancy-Related Complications
By preventing unplanned pregnancies, subdermal implants can help reduce the risk of pregnancy-related complications, such as ectopic pregnancy, preterm birth, and low birth weight.
No Hormonal Side Effects for Partners
Since the hormones only affect the woman, partners do not have to worry about any hormonal side effects that can occur with other methods, such as changes in mood or libido.
Minimal User Error
The implant is inserted by a healthcare provider and requires no daily maintenance. This means there’s no risk of user error, such as missing a pill or forgetting to apply a patch.
Risks and Side Effects of Subdermal Contraceptive Implants
Hormonal Side Effects
Like all hormonal methods, subdermal implants can cause some side effects. These may include menstrual irregularities, mood swings, breast tenderness, and acne. However, these effects tend to be less severe than with some other hormonal methods.
Insertion and Removal Procedures
The implant must be inserted and removed by a healthcare provider. While this is a minor procedure, it can be uncomfortable and may carry a small risk of infection.
Risk of Infection
There is a small risk of infection at the site where the implant is inserted. This is usually preventable with proper care and hygiene.
Weight Gain
Some women may experience weight gain while using subdermal implants, although this is not common.
Implant Displacement
In rare cases, the implant may move from its original position, which could reduce its effectiveness. It’s important to follow up with a healthcare provider to ensure the implant is still in place.
Risks for Women with Certain Health Conditions
Women with certain health conditions, such as breast cancer or liver disease, may not be suitable candidates for subdermal implants. It’s important to discuss these risks with a healthcare provider.
Return to Fertility
After the implant is removed, fertility typically returns quickly. However, it’s important to use an additional method of contraception until two normal menstrual cycles have occurred, as the implant can delay the return of ovulation.
Conclusion
Subdermal contraceptive implants offer a highly effective, convenient, and long-acting method of birth control. However, like all medical interventions, they come with risks and potential side effects. It’s important to discuss the benefits and risks with a healthcare provider to determine if subdermal implants are the right choice for you.
