Family Planning Series – Week 8:

( Injectable Contraceptives )

 What are Injectable Contraceptives?

They are hormonal birth-control injections that prevent ovulation and thicken cervical mucus, making it harder for sperm to reach the egg.  

The most common types are:  

• Depo-Provera  150 mg Medroxyprogesterone acetate | IM | Every 3 months (13 weeks)
• Sayana Press  104 mg Medroxyprogesterone acetate | SC | Every 3 months (13 weeks) 
• Noristerat 200 mg Norethisterone enanthate  IM | Every 2 months.

How They Work ?

1️⃣ Inhibit ovulation.  

2️⃣ Thicken cervical mucus to block sperm.  

3️⃣ Thin the uterine lining to prevent implantation.  

Advantages :

✅ Very effective (97–99% if taken on time).  

✅ Long-acting and reversible.  

✅ Safe for breastfeeding (after 6 weeks postpartum).  

✅ Can reduce menstrual pain and bleeding.  

✅ Suitable for women who can’t take estrogen.  

⚠️ Possible Side Effects:

- Irregular bleeding or no periods.  

- Mild weight gain or bloating.  

- Headache or mood changes.  

- Delayed fertility return (4–10 months) after last dose.  

- Slight bone density reduction if used for more than 2 years.  

- Does not protect against HIV or STIs.

 📋 Guideline Notes (WHO & ACOG):

- Start within first 7 days of menstruation or 6 weeks postpartum.  

- Keep injections on schedule (every 8–13 weeks depending on type).  

- If > 2 weeks late → rule out pregnancy before reinjection.  

- Regular BP check and counseling about delayed fertility are essential.  

💬 Key Message :

Injectables are safe, effective, and convenient — but timing and follow-up are everything.  

They don’t protect against STIs, so condoms are still important for protection.
