How Do You Use RU486?

It is important to note that the abortion pill isnot the same thingas the morning-after pill.

You may need an additional dose of medication or a procedure to complete the abortion.

How It Works

RU486 blocks the progesterone receptors in your body.

Progesterone is the hormone responsible for causing the uterine lining to build up and prepare for pregnancy.

Then, the misoprostol will cause uterine contractions.

This allows your uterus to be emptied.

Who Can Use It?

It can be used safely in women of any age, including those under 17 years old.

RU486 Side Effects

You should expect to feel some side effects after using the abortion pill.

These can include:

If you have severe pain or feel faint, get medical attention.

And if you have a fever after the day you take the misoprostol, call your healthcare provider.

The medication is also contraindicated for people with:

Interactions

Mifeprex can negatively interact with certain medications.

Also, know that RU486 does not offer protection against sexually transmitted diseases.

The bleeding after your abortion marks the start of a new menstrual cycle.

This means that your normal period should return in four to eight weeks.

Keep in mind that you may have all types of feelings after a medical abortion.

Because of the sudden change in your hormone levels, you may become more emotional.

How Much Does RU486 Cost?

you might check with your private insurance to see if they cover medical abortion.

That being said, the abortion pill may cost up to $800, but it usually costs less.

The final cost depends on whether or not you need additional tests, healthcare provider visits, and/or exams.

The cost of RU486 can also vary depending on your state.

RU486 is available at many Planned Parenthood clinics.

Bleeding typically begins two to four hours after Cytotec (misoprostol), the second medication in the series.

In some cases, a second dose of Cytotec may be needed.

This means you’re able to drive yourself to your appointment and home again.

However, the second medication commonly causes cramping and heavy bleeding.

Many women prefer to stay home and rest.
