Everything You Need to Know About the Contraceptive Implant: Your Guide to Hassle-Free Birth Control
Choosing the right birth control can feel like navigating a maze. From daily pills to barrier methods, the options are vast. However, if you are looking for a highly effective, “set-and-forget” solution, the contraceptive implant might be your perfect match. This tiny, flexible rod is discreetly placed under the skin of your upper arm and provides protection against pregnancy for up to three years.
In this guide, we will explore how this long-acting reversible contraception (LARC) works, the fitting process, and what you can expect regarding potential Nexplanon side effects. Our goal is to empower you with the facts so you can make an informed decision about your reproductive health.
What exactly is the contraceptive implant?
The contraceptive implant (often known by the brand name Nexplanon) is a small, plastic rod about 4cm long—roughly the size of a matchstick. It is a form of hormonal birth control that steadily releases the hormone progestogen into your bloodstream. Because it does not contain oestrogen, it is often a preferred choice for those who cannot utilise combined hormonal methods due to medical reasons or personal preference.
This progesterone-only method works in three distinct ways to prevent pregnancy:
- It prevents the release of an egg from the ovaries (ovulation) each month.
- It thickens the cervical mucus, making it difficult for sperm to move through the cervix.
- It thins the lining of the womb, so a fertilised egg is less likely to implant itself.
According to the NHS, the implant is over 99% effective, making it one of the most reliable forms of contraception available today.
The Fitting and Removal Process
Getting the subdermal implant fitted is a quick procedure that can be performed at your local general practitioner (GP) surgery or a sexual health clinic. You don’t need a general anaesthetic; instead, a healthcare professional will use a local anaesthetic to numb the area on the inside of your non-dominant upper arm.
Once the area is numb, the implant is inserted just under the skin using a specially designed applicator. You won’t need stitches, but you might notice some arm bruising, tenderness, or swelling for a few days afterward. Professionals at the Mayo Clinic suggest keeping the area dry and covered for a short period to aid healing.
Removal is just as straightforward. When the three years are up, or if you decide you want to try for a baby sooner, a doctor or nurse will make a tiny incision to slide the rod out. One of the greatest benefits is the rapid return of fertility after removal; most people find their natural cycle returns to normal within a few weeks.
Pros and Cons: Is it Right for You?
Every body is unique, and what works for one person may not work for another. It is important to weigh the convenience of a fit and forget method against potential changes to your cycle. Research from the FPA (Family Planning Association) highlights that while many users love the freedom it provides, others find the hormonal changes challenging.
To help you decide, here is a comparison of the key benefits and drawbacks:
| Advantages | Disadvantages |
|---|---|
| Highly effective (99%+) for 3 years | May cause irregular bleeding or spotting |
| Safe to use while breastfeeding | Does not protect against STIs |
| Can reduce heavy, painful periods | Requires a minor procedure for fitting/removal |
| No daily “pill-taking” anxiety | Some users report weight gain and Nexplanon concerns |
Managing Nexplanon Side Effects
Like all medications, the contraceptive implant can cause side effects as your body adjusts to the hormones. The most common issue reported is irregular bleeding. For some, periods may become lighter, more frequent, or stop altogether. Data from NICE suggests that about 1 in 3 users will stop having periods after a year of use.
Other potential side effects include:
- Mood swings or low mood.
- Acne or skin changes.
- Headaches.
- Breast tenderness.
If you are concerned about weight gain and Nexplanon, it is worth noting that clinical studies, such as those cited by the World Health Organization (WHO), have found no definitive evidence that the implant causes significant weight gain for the majority of users. Often, lifestyle factors or natural age-related changes play a larger role.
Contraceptive coil vs implant: Which LARC should you choose?
When comparing contraceptive coil vs implant options, the main difference lies in placement and hormone delivery. The coil (IUD or IUS) is inserted into the womb by a specialist, while the implant stays in the arm. Both are excellent LARC options. You can find more detailed comparisons on the Sexwise website or by consulting the CDC guidelines on contraceptive efficacy.
Who should avoid the implant?
While safe for most, certain medical conditions may make the implant unsuitable. It is essential to discuss your medical history with your general practitioner (GP). According to the Faculty of Sexual and Reproductive Healthcare (FSRH), you should mention if you have:
- Unexplained vaginal bleeding.
- Severe liver disease.
- A history of breast cancer.
- Serious heart disease or a history of stroke.
For more specific drug interactions, refer to the official Patient Information Leaflet.
Where to get the implant fitted
In the UK, you can access the contraceptive implant for free through various channels. You do not always need a referral from your doctor. Options include:
- Your local general practitioner (GP) surgery.
- Community sexual health clinics (such as Sexual Health London).
- Young people’s clinics like Brook.
Organisations like Patient.info provide directories to help you find the nearest centre for your protection against pregnancy needs.
Frequently Asked Questions (FAQs)
Does the fitting of the contraceptive implant hurt?
The procedure is generally painless because a local anaesthetic is used to numb the area. You may feel a slight stinging sensation during the anaesthetic injection, and some arm bruising or soreness is common for a few days after the procedure. Experts at the Cleveland Clinic reassure patients that the actual insertion takes only a minute.
Can the implant move around my body?
While it is rare, the implant can move slightly from its original position. However, it cannot travel to other parts of your body like your heart or lungs if fitted correctly. You should be able to feel the rod under your skin. If you can no longer feel it, contact your sexual health clinic immediately. Guidance from the RCOG emphasises the importance of regular self-checks.
Will my fertility be affected after I take it out?
No. One of the major benefits of this hormonal birth control is that there is no delay in fertility after removal. Once the rod is gone, the progestogen leaves your system very quickly, and you can become pregnant as soon as your next ovulation cycle begins.
Conclusion
The contraceptive implant offers an incredible level of security and convenience for those looking to prevent pregnancy without the daily hassle of pills. While Nexplanon side effects like irregular bleeding can occur, many find the benefits of this fit and forget method far outweigh the initial adjustment period. Whether you are planning your future or simply want peace of mind, speak with a healthcare professional today to see if the implant is the right choice for your lifestyle.
