Overview
Contraceptive injections are a long-acting hormonal method for preventing pregnancy. They contain progestin, a synthetic hormone that suppresses ovulation, thickens cervical mucus, and alters the uterine lining to prevent fertilization and implantation.
Importance of contraceptive injections:
- Highly effective with ~94–99% efficacy when administered on schedule.
- Provides long-term protection for 1–3 months per injection depending on the type.
- Non-daily method, ideal for women who prefer minimal routine attention.
- Suitable for women who cannot use estrogen-containing contraception.
In South Korea, contraceptive injections are offered in gynecology clinics, family planning centers, and hospitals, with medical supervision ensuring safe administration and follow-up.
Why It’s Done
Contraceptive injections are used for reliable, long-term pregnancy prevention and, in some cases, to manage menstrual disorders.
Common indications include:
- ➤ Long-term contraception without daily or weekly intervention.
- ➤ Women with difficulty adhering to daily pills.
- ➤ Medical contraindications to estrogen (smokers over 35, hypertension, migraines with aura).
- ➤ Management of heavy or irregular menstrual bleeding.
- ➤ Temporary spacing of pregnancies for health, education, or lifestyle reasons.
Benefits for users:
- ✔️ High efficacy when injections are on schedule.
- ✔️ Reversible; fertility returns within months after stopping.
- ✔️ Reduces risk of unintended pregnancy, improving reproductive autonomy.
- ✔️ Convenient and discreet, with minimal daily attention required.
- ✔️ Can help regulate menstrual cycles for some users.
Alternatives
Contraceptive injections are one option among many long-acting or short-term contraceptives:
- ➤ Hormonal pills: Combined or progestin-only oral contraceptives.
- ➤ Contraceptive implants: Long-term rod under the arm releasing hormones.
- ➤ Intrauterine devices (IUDs): Hormonal or copper options.
- ➤ Barrier methods: Condoms, diaphragms, or cervical caps.
- ➤ Permanent sterilization: Tubal ligation or vasectomy.
- ➤ Fertility awareness methods: Tracking ovulation to avoid intercourse during fertile periods.
Key point: Injections are ideal for users seeking medium-term, low-maintenance contraception without daily pills or invasive devices.
Preparation
Proper preparation ensures safe administration, patient understanding, and effective protection.
Steps include:
- ✅ Medical assessment: Review health history, allergies, previous contraceptive use, and menstrual patterns.
- ✅ Method selection: Choose injection type (e.g., Depo-Provera or 3-month progestin injections).
- ✅ Patient counseling: Discuss schedule, side effects, expected menstrual changes, and backup contraception if needed.
- ✅ Consent: Obtain informed agreement from the patient.
- ✅ Site preparation: Clean injection site (usually upper arm, thigh, or buttock) with antiseptic.
Important: Preparation ensures safe use, adherence, and patient satisfaction.
How It’s Done
Contraceptive injections are administered by trained healthcare providers and do not require hospitalization.
Procedure steps:
- Assess injection site: Upper arm, thigh, or buttock.
- Apply antiseptic and local prep: Clean the site to prevent infection.
- Injection: Administer hormone via intramuscular (IM) or subcutaneous (SC) injection, depending on product.
- Post-injection care: Apply gentle pressure or bandage; advise patient to avoid strenuous activity for a short period.
Schedule:
- Typical injections are every 1–3 months depending on the formulation.
- Timely follow-up is critical for maintaining contraceptive effectiveness.
Key point: Injections are quick, outpatient procedures that provide medium-term contraception with minimal daily management.
Recovery & Post-Use Care
Recovery is generally immediate, with minor monitoring for side effects.
Immediate post-injection:
- Monitor for mild pain, swelling, or bruising at the injection site.
- Watch for allergic reactions (rare).
Short-term care:
- Track menstrual changes, including irregular bleeding or amenorrhea.
- Use backup contraception if injection is delayed.
Long-term outcomes:
- Highly effective contraception for 1–3 months per dose.
- Fertility generally returns within 3–12 months after discontinuation.
- Provides reliable family planning and reproductive autonomy.
Important: Regular follow-up ensures timely injections, side effect management, and sustained protection.
Possible Complications / Risks
Contraceptive injections are safe, but potential risks include:
- ⚠️ Injection site reactions: Pain, swelling, redness, or bruising.
- ⚠️ Menstrual irregularities: Spotting, prolonged bleeding, or absence of periods.
- ⚠️ Hormonal side effects: Headaches, weight gain, mood changes, or breast tenderness.
- ⚠️ Bone density reduction: Rare with long-term use (particularly with Depo-Provera), reversible after discontinuation.
- ⚠️ Delayed return to fertility: Fertility may take a few months to resume after stopping injections.
In South Korea, contraceptive injections are administered under medical supervision, with counseling and monitoring to reduce risks and manage side effects effectively.
