Contraceptive Implant: Advantages & Disadvantages

The contraceptive implant, often referred to by its brand name, Nexplanon, is a small, flexible rod inserted under the skin of the upper arm. It provides highly effective, long-term contraception and has become a popular choice for many individuals. However, like any medical intervention, it comes with its own set of benefits and potential downsides. This guide aims to provide a balanced overview of the advantages and disadvantages of the contraceptive implant to help you make an informed decision.

Introduction to the Contraceptive Implant

The contraceptive implant works by releasing a hormone called progestin (a synthetic form of progesterone) into your bloodstream. This hormone prevents pregnancy by:

Inhibiting ovulation: Preventing the release of eggs from the ovaries.
Thickening cervical mucus: Making it more difficult for sperm to reach an egg.
Thinning the uterine lining: Reducing the likelihood of implantation.

The implant is over 99% effective at preventing pregnancy, making it one of the most reliable contraceptive options available. However, understanding both the positives and negatives can help you decide whether it is the right choice for your lifestyle and health needs.

Advantages of the Contraceptive Implant

Highly Effective

With a failure rate of less than 1%, the implant is one of the most reliable forms of contraception. Once inserted, it provides continuous protection for up to three years without the need for daily or monthly attention.

Long-Lasting but Reversible

The implant offers long-term protection, but it’s also easily reversible. If you decide you want to conceive or no longer wish to use it, the implant can be removed at any time, with fertility ( the chance to get pregnant) returning immediately.

Low Maintenance

Unlike daily contraceptive pills or monthly injections, the implant requires no regular upkeep. Once it’s in place, there’s no need to remember to take or apply anything.

Discreet

The implant is a discreet option, as it is inserted under the skin and not externally visible. This makes it appealing for individuals who prefer a private method of contraception.

Suitable for Those Who Can’t Take Oestrogen

For individuals who cannot use estrogen-containing contraceptives (such as the combined pill or patch), the implant is a safe alternative as it contains only progesterone.

Reduces Heavy or Painful Periods

For some individuals, the implant can lead to lighter, less painful periods, and in some cases, periods may stop altogether. This can be a welcome relief for those who experience heavy menstrual bleeding or dysmenorrhea (painful periods).

Safe During Breastfeeding

The implant is safe to use while breastfeeding and does not affect milk supply or quality, making it a suitable option for new mothers.

Non-Interference with Daily Activities

Once inserted, the implant does not interrupt sexual activity or other aspects of daily life. It works in the background, providing protection without requiring any additional steps.

Disadvantages of the Contraceptive Implant

Irregular Bleeding

One of the most common side effects of the implant is irregular bleeding. This can include:

Spotting between periods.
Prolonged or frequent bleeding.
In some cases, no bleeding at all (amenorrhea).

While this is not harmful, it can be inconvenient or difficult to manage, for some individuals.

Hormonal Side Effects

Some users experience side effects related to the hormone progestin, which may include:

Mood changes, including mood swings or mild depression.
Acne or skin changes.
Breast tenderness.
Headaches.
Decreased sex drive.
Bloating

These effects can improve over time, but for some, they may persist and require consideration of alternative methods.

Potential for Pain or Discomfort During Insertion/Removal

The implant must be inserted and removed by a trained healthcare professional. While the procedure is straightforward and local anesthesia is used, the local anesthetic does sting when injected until the area becomes numb. The anesthetic will take away all pain sensations, it does not remove the pressure or touching sensation. After a fit or removal, it is common to have some slight discomfort and soreness together with some bruising at the insertion site.

No Protection Against STIs

The contraceptive implant does not provide protection against sexually transmitted infections (STIs). If you are at risk of STIs, using condoms alongside the implant is essential for protection.

Requires a Procedure for Removal

Although removal is straightforward, it requires a visit to a healthcare provider. This may be inconvenient for some individuals, particularly if access to healthcare is limited. It will involve an injection of local anesthetic and a tiny 2mm cut to the skin, to remove the implant.

Rare Complications

In rare cases, complications such as infection, migration of the implant, or difficulty removing the implant may occur. These are uncommon but can require additional medical attention.

Not Suitable for Everyone

The implant may not be recommended for individuals with certain health conditions, such as:

Unexplained vaginal bleeding.
Severe liver disease.
A history of breast cancer.

It’s important to discuss your medical history with us to ensure the implant is safe for you.

Who Might Benefit Most from the Implant?

The contraceptive implant may be particularly beneficial for individuals who:

Want or need a highly effective, long-term contraceptive option.
Prefer a “fit and forget” method that doesn’t require daily attention.
Cannot use estrogen-containing contraceptives.
Experience heavy or painful periods and are looking for relief.
Are breastfeeding and need a compatible contraceptive.

Who Might Find the Implant Less Suitable?

The implant might not be the best choice if you:

Prefer a method with predictable bleeding patterns.
Are sensitive to hormonal contraceptives or experience significant side effects.
Have a medical condition that makes progestin-based contraception unsuitable.
Are looking for a contraceptive that also protects against STIs.

Balancing the Pros and Cons

Deciding whether the contraceptive implant is right for you depends on your individual preferences, health history, and lifestyle. While its effectiveness and convenience are undeniable, the potential for irregular bleeding or hormonal side effects may be off-putting for some.
