Treatment Overview
In most cases, an
ectopic pregnancy is treated right away to avoid
rupture and severe blood loss. The decision about which treatment to use
depends on how early the pregnancy is detected and your overall condition. For
an early ectopic pregnancy that is not causing bleeding, you may have a choice
between using medicine or surgery to end the pregnancy.
Medication. Using
methotrexate to end an ectopic pregnancy spares you
from an incision and
general anesthesia. But it does cause side effects and
can take several weeks of hormone blood-level testing to make sure that
treatment has been successful. Methotrexate is most likely to work:
- When your pregnancy hormone levels (human
chorionic gonadotropin, or hCG) are low (less than 5,000).
- During
the first 6 weeks of pregnancy.
- When the embryo has no heart
activity.
Surgery. If you have an ectopic pregnancy
that is causing severe symptoms, bleeding, or high hCG levels, surgery is
needed. This is because medicine is not likely to work and a rupture becomes
more likely as time passes. Whenever possible,
laparoscopic surgery that uses a small incision is
done. For a
ruptured ectopic pregnancy, emergency surgery is
needed.
Expectant management. For an early ectopic
pregnancy that appears to be naturally miscarrying (aborting) on its own, you
may not need treatment. Your health professional will regularly test your blood
to make sure that your pregnancy hormone (hCG, or human chorionic gonadotropin)
levels are dropping. This is called
expectant management.
Ectopic pregnancies can be resistant to treatment.
- If hCG levels do not drop or bleeding does not
stop after taking methotrexate, your next step may be surgery.
- If
you have surgery, you may take methotrexate afterward.
If your blood type is
Rh-negative,
Rh
immunoglobulin is used to protect any future pregnancies against
Rh sensitization. For more information, see the topic

What To Think About
Surgery versus medication
- Methotrexate is usually the first treatment
choice for ending an early ectopic pregnancy. Regular follow-up blood tests are
needed for days to weeks after the medicine is injected.
- There are
different types of surgery for a tubal ectopic pregnancy—when possible, only a
slit is made in the fallopian tube (salpingostomy), rather than removing a
section of the tube (salpingectomy).
- On average, salpingostomy is
equal to methotrexate (for an early ectopic pregnancy) in terms of being
effective and preserving a woman's ability to become pregnant in the
future.9
- Although surgery is a faster
treatment, it can cause scar tissue that could cause future pregnancy problems.
Tubal surgery may damage the fallopian tube, depending on where and how big the
embryo is and the type of surgery needed.
Surgery may be your only treatment option if an ectopic pregnancy
has gone past 6 weeks or if you have internal bleeding.
