If you throw up within 20 minutes of taking misoprostol, how you administered the medication determines whether your body absorbed it.
The physical route you used dictates your immediate next steps:
1. If You Let the Pills Dissolve in Your Mouth (Under Tongue or in Cheek)
If you held the misoprostol tablets under your tongue or inside your cheeks for 30 full minutes before swallowing them—and then threw up 20 minutes later—your dose is completely safe.
-
Why: The active ingredients are absorbed directly through the mucous membranes in your mouth during those first 30 minutes. Once that time window passes, swallowing the remaining pill fragments is just a formality; your body has already received the full medical dose.
2. If You Swallowed the Pills Immediately
If you swallowed the misoprostol pills raw like a standard tablet with water and threw them up 20 minutes later, your body likely did not absorb the medication.
-
Why: The stomach takes longer than 20 minutes to break down and absorb the active components of the tablet.
3. If You Inserted the Pills Vaginally
If you inserted the tablets directly into your vagina and threw up 20 minutes later, your dose is safe.
-
Why: Vomiting does not impact the absorption taking place inside the vaginal canal. As long as the physical pills did not fall out when you went to the bathroom, they are actively working.
What You Need to Do Next
If you fell into Category 2 (swallowed them early) or if you threw up during the 30-minute window while they were still dissolving in your mouth, you should contact your clinician right away. You will most likely need a replacement dose of misoprostol to ensure the treatment successfully empties the uterus.
To prevent nausea from interfering with your next steps, make sure you utilize anti-nausea medications (like Zofran/ondansetron) roughly 30 minutes before attempting another dose.
