Medical Abortion

加州大学旧金山分校健康中心支持从一个人确认怀孕到最后一次月经后11周的药物流产. 虽然这种方法是fda批准的10周，但研究表明，11周的安全性和有效性.

药物流产的成功率在95%到98%之间, 导致妊娠完全通过而不使用器械. In comparison, aspiration abortion is effective about 99 percent of the time.

Medications for abortion

The pills prescribed for medication abortion at the UCSF Center for Pregnancy Options are mifepristone followed by misoprostol.

Mifepristone, also known as "Mifeprex" or "RU-486,阻断子宫内天然激素黄体酮的作用. 这使得子宫对第二种药物米索前列醇敏感. 米索前列醇会导致子宫收缩，导致出血和痉挛.

How a medical abortion works

A medication abortion involves an initial evaluation, taking of the prescribed medication, and confirmation that the abortion was successful.

第一次评估通常包括门诊检查和超声检查, though for people who meet certain criteria, this visit can be done by telehealth if the person prefers.

Initial evaluation

Clinic medication abortion. Come to the office visit for an exam and counseling. 十大赌博平台排行榜会给你200毫克，也就是1片米非司酮. 这通常是在诊所进行的，但也可以在以后进行，以优化您的时间.

No-test (telemedicine) medication abortion. 这种选择适用于以下人群:(1)没有异位(或“输卵管”)妊娠的风险因素, (2) no symptoms of ectopic pregnancy, (3) regular periods, (4) a known day of last menstrual period, and (5) no recent use of hormonal contraception. 所有这些都必须适用于你跳过诊所评估. 您将与诊所工作人员进行视频访问，以确认信息, then a video visit with the clinician. 你可以开车到诊所去取药，也可以花钱把药寄给你.

Taking the medication

One or two days after you take the mifepristone, you'll place four tablets, or 800 micrograms, of misoprostol in your cheeks or vagina. You will be given instructions on how to do this.

If you are at 9 weeks or more of pregnancy, 三小时后，再服用四片米索前列醇片.

Follow-up care

为了确认流产是否成功，你可以通过以下三种方式之一进行评估:

• For people who had an initial ultrasound, 6至14天后可在诊所进行后续超声检查.
• 你可以在服用米非司酮的当天做血液检查，几天后再做一次，以确认怀孕的通过.
• 电话或远程医疗访问可以确认适当的症状，如果没有担心, 你在怀孕后4到5周做尿妊娠试验.

Medication abortion vs. emergency contraception

药物流产与紧急避孕不同, also referred to as the "morning-after pill" or "EC." Emergency contraception keeps you from getting pregnant. 因此，在您怀孕后，EC不再有效. 另一方面，药物流产是用来终止妊娠的.

Medication abortion vs. miscarriage treatment

用于流产的相同药物也可用于治疗流产，只是略有不同.

During a miscarriage, even though the pregnancy has ended, 妊娠物质有时会留在患者体内，对患者的健康构成威胁. When this happens, these medications can help to expel it.

Safety and side effects

Mifepristone has been studied for over 25 years. 全十大赌博平台排行榜数以百万计的孕妇使用米非司酮和米索前列醇或类似的药物进行流产. 米非司酮被列入十大赌博平台排行榜卫生组织的“基本药物”清单." All studies have shown the method to be safe and effective; there have been no reports of any long-term risks. 大出血需要输血是极其罕见的，发生在小于0.5 percent of patients.

Short-term side effects of a medical abortion include:

• Strong cramps
• Bleeding
• Nausea and vomiting
• Fever and chills

没有证据表明米非司酮用于药物流产有长期风险，米索前列醇也没有长期影响.

没有迹象表明任何早期堕胎方法会影响未来的生育能力.

在极少数情况下，药物不起作用，你选择继续怀孕, 接触米索前列醇会有出生缺陷的风险. 关于米非司酮对发育中的胚胎的影响我们所知甚少.

Cost and insurance

The cost of a medication abortion varies by clinic. 一些医疗机构对药物和人工流产收取类似的费用. 许多保险公司，包括Medi-Cal，会支付药物流产的费用. 《十大赌博平台排行榜》要求所有加州许可的医疗保险计划涵盖终止妊娠(流产和堕胎)的护理，而不需分担费用(没有共付额或免赔额)。.

加州大学旧金山分校怀孕选择中心为没有保险的人提供自费药物和人工流产的选择，这些人没有资格获得怀孕服务Medi-Cal(高达联邦贫困水平的213%).
