Pregnancy Testing Before Depo-Provera Injection

Clinical Approach to DMPA Initiation

The Centers for Disease Control and Prevention recommends that a pregnancy test is not required before administering Depo-Provera (DMPA) injection, among healthy women, with no examinations or tests needed before initiation of DMPA 1, 2, 3
DMPA can be initiated during the first 5-7 days of a normal menstrual cycle, with no backup contraception needed, as recommended by the Centers for Disease Control and Prevention 1, 4
The Centers for Disease Control and Prevention suggests that DMPA can be initiated at any time if reasonably certain the patient is not pregnant, with backup contraception needed for 7 days if more than 7 days since menses started 1, 3
Immediately postabortion, DMPA can be given with no backup needed if given at the time of surgical abortion, as recommended by the Centers for Disease Control and Prevention 5, 4
Postpartum, DMPA can be given immediately, with backup contraception requirements based on timing and breastfeeding status, according to the Centers for Disease Control and Prevention 4

Studies found that delaying DMPA initiation was associated with more unintended pregnancies than immediate receipt of DMPA, with a low risk of harm, as reported by the Centers for Disease Control and Prevention 6, 1
DMPA injections given up to day 7 of the menstrual cycle inhibited ovulation, and cervical mucus became unfavorable for sperm penetration in 90% of women within 24 hours, as found by the Centers for Disease Control and Prevention 6, 1

Before giving DMPA, ensure the patient does not have unexplained vaginal bleeding, as recommended by the Centers for Disease Control and Prevention 6
Liver disease is a contraindication to DMPA, according to the Centers for Disease Control and Prevention 6
Known pregnancy is a contraindication to DMPA, as stated by the Centers for Disease Control and Prevention 1

When starting Depo-Provera as a new contraceptive method, if the injection is given more than 7 days after the menstrual period started, backup contraception should be used for 7 consecutive days after the injection, as recommended by the American Academy of Family Physicians 7, 8, 9, 10, 11, 12, 13
If the injection is given outside the optimal window, it should be treated as a "new start" and backup contraception should be used for 7 consecutive days after the injection, according to the American Academy of Family Physicians 7, 8, 9, 10, 11, 12, 13

Emergency contraception should be considered if unprotected intercourse occurred in the 5 days before receiving the Depo-Provera injection, especially if the injection was given during the first week of the cycle, as advised by the American Academy of Family Physicians 7, 8, 9, 10, 11, 12, 13
The American Academy of Family Physicians recommends that patients should not discontinue their current contraceptive pill prematurely if they receive the injection outside the first week of their cycle, to ensure continuous contraceptive protection 7, 8, 9, 10, 11, 12, 13
