When the time isn’t right to start or grow your family, birth control offers a reliable and convenient way to manage your contraceptive care. Although several choices are available, two of the most common progestin-only methods are the birth control shot (Depo-Provera) and the birth control implant (Nexplanon).
Both provide long-lasting pregnancy prevention but work in different ways. Find out the differences between the shot and implant to make an informed decision about your contraceptive care.
The Shot
The birth control shot is an injectable contraceptive that offers long-term pregnancy prevention. As a progestin-only method, it does not contain estrogen, making it a suitable option for individuals who cannot use combination hormonal contraceptives.
How It Works
Women who value convenience often favor the shot as it’s only administered once every three months. It works primarily by blocking ovulation, thickening the cervical mucus to stop sperm, and thinning the uterine lining to prevent implantation. For maximum effectiveness, it must be received on a schedule.
Pros:
- Highly Effective – When used correctly, the shot is over 99% effective.
- Low Maintenance – Only requires an injection every three months, reducing the need for daily or frequent reminders.
- Discreet – There are no visible signs of birth control, and it does not require insertion or a device.
- May Reduce Menstrual Symptoms – Many users experience lighter periods or stop having periods altogether over time.
- Estrogen-Free – A good option for women who cannot take estrogen-based contraceptives.
Cons:
- Requires Regular Injections – Missing a shot can reduce effectiveness, requiring strict adherence to a schedule.
- Potential Side Effects – May cause weight gain, mood changes, headaches, and irregular bleeding.
- Bone Density Loss – Long-term use has been linked to decreased bone mineral density, which may be a concern for some users.
Depo-Provera
Depo-Provera is the brand name for a birth control shot that contains depot medroxyprogesterone acetate (DMPA) as its active ingredient. It is typically injected into the muscle of the upper arm or buttocks. As it lasts for three months, it provides a convenient alternative for those who prefer not to take daily birth control pills but are not ready for longer-term options, such as an implant or IUD.
The Implant
The birth control implant is a long-acting, reversible contraceptive that provides years of highly effective pregnancy prevention. It’s a tiny, flexible rod measuring approximately 1.6 inches and is inserted just under the skin of the upper arm.
How It Works
Implants work by releasing steady, low doses of progestin into the bloodstream to block ovulation, thicken cervical mucus to stop sperm, and thin the uterine lining to prevent implantation. Once inserted, it remains effective for up to 3 years.
Pros:
- Extremely Effective – Over 99% effective at preventing pregnancy, with a failure rate lower than most other contraceptive methods.
- Long-Lasting – Protects against pregnancy for three years without requiring maintenance.
- Low-Hormone Option – Releases a consistent, low dose of progesterone, avoiding hormonal fluctuations.
- Reversible – Can be removed at any time, and fertility typically returns quickly after removal.
- Estrogen-Free – Suitable for individuals who cannot use estrogen-containing birth control.
Cons:
- Requires a Minor Procedure – Must be inserted and removed by a healthcare provider, which may cause slight discomfort.
- Potential Side Effects – Some users experience irregular bleeding, headaches, mood changes, or weight gain.
- Not Suitable for Everyone – May not be recommended for individuals with certain medical conditions, such as those with a history of blood clots.
Nexplanon
Nexplanon is the most commonly used brand of birth control implant. The tiny plastic rod is placed under the skin of the upper non-dominant arm in a fast outpatient procedure. Nexplanon is radiopaque, meaning it can be detected by X-ray if necessary. Once inserted, it continuously releases progestin to provide long-term pregnancy prevention, making it a highly convenient and effective contraceptive option.
Which Option Is Best for You?
Choosing between the birth control shot and implant depends on your lifestyle, health needs, and personal preferences. If you prefer a low-maintenance, long-term option that lasts for years, the implant may be the best choice.
However, if you like the flexibility of an injectable method that isn’t permanent, the shot may be a better fit. Consider factors such as side effects, scheduling requirements, and future pregnancy plans. Always consult with a healthcare provider to determine the best contraceptive care for you.
