For ectopic pregnancies, many times you have a choice between taking a medication or having surgery. Right now, there is just one medication used to treat ectopic pregnancies, called methotrexate. This medication stops the growth of cells that are chop-chop dividing, such equally pregnancy cells. It was originally adult to be a cancer drug, because cancer is also a condition where cells are chop-chop dividing. And because it is a cancer drug, it is only given in hospitals and under very conscientious monitoring circumstances.

choosing methotrexate

Methotrexate for ectopic pregnancy works equally well as surgery in certain situations:

  • You have depression pregnancy hormone levels (<5000)
  • An embryo isn't seen in the pregnancy sac or if the embryo doesn't have a heartbeat yet
  • If the ectopic pregnancy is small or isn't even visible on ultrasound.

But if these conditions aren't present, the methotrexate has a higher chance of not working. It's of import to have a long conversation with your md nearly what the chances are of information technology working or not working for you.

Methotrexate is given equally an intramuscular injection, most often into your buttocks. There are a few different dosing regimens—a unmarried injection, 2 doses three days apart, or multiple doses every other day for at to the lowest degree a week. Which schedule of treatment your doctor chooses is in part based on how far along your pregnancy is, how high your pregnancy hormone levels are, and how large the ectopic pregnancy is on ultrasound. The further forth in the pregnancy you are, the more doses of methotrexate you usually receive.

coming dorsum for blood tests

Afterwards you get your first dose of methotrexate, your doc is going to requite you a very detailed schedule of when to come back for claret tests. These tests monitor the levels of your pregnancy hormone. Fifty-fifty though your hormones may go upwards initially after y'all go the methotrexate, they should before long thereafter start to come down. Your dr. is watching nigh advisedly for the pregnancy levels betwixt day iv of treatment—in reality the 3rd day after the injection, as the injection 24-hour interval is considered "day 1"—and the level on twenty-four hours seven.

Your md is expecting to run into a 15% drop in the level of pregnancy hormone between these two tests. If your hormone levels have dropped that much in this start calendar week, then you'll commonly get blood tests on a weekly basis until the hormone level reaches essentially zero. This can have as short every bit four weeks, just it tin can take up to iii months depending on how long it takes for the pregnancy to resolve.

importance of the testing schedule

Your doctor may seem very obsessive, telling y'all nearly which days yous must come back for testing. This focus on specific days reflects the knowledge that we have nearly how the hormone levels drop after methotrexate if the medication is working to treat an ectopic pregnancy. The day four and 24-hour interval seven values are very of import because it'south specifically here that the 15% drop needs to be seen for us to exist reassured that the medication is working. If y'all miss i of these blood draws, your doctor needs to guess what the levels might take been. Even if she's super-smart, she's non a magician, and it's very hard to so know if the ectopic is being fairly treated.

1 of the reasons that a person might not choose methotrexate for ectopic pregnancy and may choose surgery is because information technology may be hard for her to come back on the schedule of days for the follow-upwardly. Call back well-nigh this advisedly as you're making this determination every bit to which kind of treatment you lot want.

If the pregnancy hormone levels stagnate (level off) or go back upwards, information technology'due south a sign the medication is not working. Yous may become an additional dose of methotrexate at this point, but in that location'southward a higher likelihood that you'll need surgery.

how methotrexate feels

The about common side effect of methotrexate is some cramping belly pain. This hurting usually occurs in the first one to two days of treatment. You may also beginning or continue to see vaginal bleeding or spotting, or have other GI side furnishings, like nausea, vomiting, or indigestion.

At that place are rare side effects that you need to know about, but they are much less common

  • Skin sensitivity to sunlight
  • Inflammation of the membrane covering the eye
  • Sore rima oris and throat
  • Temporary hair loss (really rare)
  • Astringent low claret counts (os marrow suppression)
  • Inflammation of the lung (pneumonitis)

The most important symptoms to look out for are an increase in pelvic hurting or any lightheadedness or dizziness. These signs could indicate that the pregnancy is starting to rupture, and that you're starting to drain internally. Also call your physician if you run into blood in your vomit, become sores on your mouth or lips, or have signs of unusual bleeding or bruising, like blood in your urine or stools that are black and tarry.

During the methotrexate treatment period for an ectopic pregnancy, stop taking your prenatal vitamins. Yous likewise demand to avoid booze, penicillin, and anti-inflammatory medications like ibuprofen or naproxen. If yous demand pain medication for cramping during this time menstruation, Tylenol is your safest choice.

how practise you lot know if methotrexate worked?

Ectopic pregnancies are deemed "treated" when your weekly hormone levels render to zero. It may be foreign to rely on blood tests, rather than your symptoms, to tell yous that the pregnancy is over. When yous take medication for a "typical" miscarriage, your body will start to have cramping and bleeding. These symptoms marker the passage of the pregnancy tissue and gives you reassurance that the pregnancy is ending. With an ectopic, though, the pregnancy doesn't "pass through" your uterus, cervix, and vagina the way a typical miscarriage does. Instead, it starts to necrose, or compress up, and eventually either passes out or may fifty-fifty be absorbed by your body. Therefore, you won't run across as much bleeding or have as much pain as you practice with a typical miscarriage.

why you lot bleed like a "regular" miscarriage

The lining of your uterus in an ectopic pregnancy is still somewhat built upwardly, notwithstanding. After all, your uterus senses pregnancy hormone, and knows that y'all're meaning. And so it's making changes to support a pregnancy even though one isn't there. Then, this fluffy lining of your uterus will need to shed, just similar a period, as the pregnancy is ending. But the bleeding looks just like that—more like a period than a miscarriage. The bleeding may first soon afterwards you get your first dose of methotrexate, or it may take a little while to starting time. So, bleeding and cramping aren't sufficient signs to know that the medication is working or not. Instead, the only thing that tells your md that things are going in the right direction are the blood tests.

It can exist actually annoying to come up back for so many blood tests, especially if you're working or in school or have kids to take care of. Just those follow up claret tests are vitally important and so yous and your md both know that the pregnancy is resolving.
