Depo-Provera Procedure
Overview
The injectable contraceptive contains a synthetic form of progesterone called medroxyprogesterone acetate. This birth control shot is given every three months and helps prevent pregnancy through multiple actions.
How It Works:
- Stops the ovaries from releasing an egg (suppresses ovulation).
- Thickens cervical mucus, which blocks sperm from entering the uterus.
- Thins the uterine lining to make it less likely for an egg to implant.
There are two forms: an intramuscular injection and a subcutaneous (under the skin) injection that delivers a lower dose. Healthcare providers administer both types.

Key Benefits of Depo-Provera
- Lowers the chance of pregnancy with a low failure rate.
- Reduces menstrual cramps and bloating.
- Makes periods lighter or may stop them completely.
- May decrease the risk of certain cancers, like endometrial cancer.
- Useful for managing health issues such as endometriosis or uterine fibroids.

However, it is not suitable for everyone, especially those with certain health conditions.
Potential Issues
The injection may cause several side effects and health concerns. Reactions vary—some people have mild issues, while others may experience stronger effects that require medical attention.
Common Side Effects
- Headaches
- Weight gain
- Abdominal pain and bloating
- Loss of interest in sex
- Depression or mood shifts
- Dizziness and weakness
- Nervous feelings
- Tiredness or feeling weak
- Irregular or heavy bleeding
- Breast tenderness
These symptoms often go away within a few months.
Bone Health Risks
One of the most discussed risks is bone mineral density loss. Over time, bones may become thinner, increasing the risk for conditions like osteoporosis. This risk is higher with a family history of osteoporosis or eating disorders. Bone loss may improve after stopping the injections, but full recovery is uncertain.
| Factor | Risk Description |
|---|---|
| Long-term use (>2 years) | Higher risk of bone thinning and osteoporosis |
| Family history | Greater chance of bone issues |
| Other medical problems | Can make bone loss worse |
Because of this, healthcare providers recommend not using this method for more than two years unless other options are not suitable.
Blood Clot and Stroke Concerns
Though rare, blood clots such as deep vein thrombosis or pulmonary embolism can occur. Stroke is also a possible risk, especially for those who smoke or have other health factors. These risks should be discussed with a healthcare professional.
Severe Allergic Reactions
In rare cases, severe allergic reactions such as anaphylaxis can happen. Symptoms include swelling, trouble breathing, or itching after the shot. Prolonged pain, redness, or pus at the injection site should be checked by a healthcare provider.
Mental Health Effects
Mood swings and depression may appear or worsen. People with a history of mental health issues should be monitored closely. Any big mood changes should be reported to a provider, friend, or family member.
Interactions and Other Risks
- Talk to a provider if you have unexplained vaginal bleeding.
- People with liver problems (like jaundice) may face complications.
- St. John’s Wort and certain other drugs can reduce effectiveness.
- Research is ongoing about potential links to breast cancer and meningioma.
Pregnancy and Return to Fertility
After stopping injections, it may take about 10 months or more to return to regular fertility. If pregnancy is a short-term goal, another method might be better.
Sexually Transmitted Infections
This method does not protect against STIs or HIV. Some studies suggest a higher risk for certain infections, like chlamydia. Use condoms for STI protection. Report any severe symptoms, such as heavy bleeding or abdominal pain, to a provider.
How You Prepare
Before starting, you’ll need a prescription. The provider will review your medical history and check your blood pressure. Bring a list of medications, including over-the-counter and herbal products. If you’re interested in administering the shot at home, ask if that’s an option.
What You Can Expect
To get the Depo-Provera injection, you follow a few simple steps. A healthcare pTo get the injection, a healthcare provider usually schedules it soon after your period starts to make sure you’re not already pregnant.
The shot is given as an intramuscular injection, typically in the upper arm or buttock. The area is cleaned with an alcohol pad, and you should avoid rubbing the site afterward.
You’ll need a new injection every 3 months (about 13 weeks). Staying on schedule is important—if more than 15 weeks pass, a pregnancy test may be required, and a backup method like condoms should be used for at least 7 days after the next injection.
Backup birth control may also be needed during the first 7 days after your very first shot, depending on when it’s given. Common changes after starting Depo-Provera include:
- Possible increase in vaginal discharge.
- Spotting or light bleeding between periods.
- Irregular periods or no periods after one year.
| Step | What Happens |
|---|---|
| Setting start date | Scheduled soon after period starts |
| Getting the injection | Clean area, give shot, no rubbing |
| Scheduling next shot | Every 3 months, no long delays |
Return on time for each shot and report unusual bleeding or discharge to your provider.
