Vomit After Taking Ibuprofen- Medical Abortion

Ibuprofen is a commonly used anti-inflammatory medication for pain and fever relief. Understanding when and how to safely repeat a dose is important to ensure effective pain management without exceeding safe dosage limits. According to general pharmacokinetic principles and implied guidance from the Therapeutic Goods Administration (TGA), absorption of ibuprofen occurs relatively quickly, with peak concentrations reached within 1-2 hours of ingestion.

When to Consult a Doctor or Pharmacist About a Repeat Dose

If you vomit after taking ibuprofen, whether or not you should take another dose depends on the timing of the vomiting and the absorption rates:

• After 30 minutes or more: The medication has already been largely absorbed (approximately 80-100%), and a repeat dose is likely not necessary.
• Between 15-29 minutes: Around 50-80% of the medication may have been absorbed. A healthcare professional may recommend a half-dose in certain cases.
• Within 0-14 minutes: Minimal absorption (less than 50%) has likely occurred. A repeat dose may be appropriate, but this should be confirmed with a pharmacist or doctor.

Managing Nausea and Vomiting with Ondansetron

If you experience persistent nausea and vomiting, you may take ondansetron to help control these symptoms. The recommended dosage of ondansetron is:

• 8 mg every 6 hours, not exceeding 24 mg within 24 hours.
• If you plan to take a repeat full or half-dose of ibuprofen, you can take ondansetron first and wait 30 minutes for it to take effect before redosing ibuprofen. This helps improve absorption and reduces the likelihood of further vomiting.

Maximum Dosages to Keep in Mind

• Ibuprofen: The maximum recommended dose for adults is 3200 mg per day, divided into doses no more frequent than every 6-8 hours.
• Ondansetron: Do not exceed 24 mg within 24 hours.

Important Safety Information

Do not take ibuprofen or ondansetron if:

• You have an allergy to ibuprofen or ondansetron.
• You have been advised by a healthcare provider not to take anti-inflammatory medications (e.g., due to kidney disease, ulcers, or bleeding disorders).
• You experience severe allergic reactions such as difficulty breathing, swelling, or rash after taking either medication.

If you are unsure about whether to take a repeat dose or experience worsening symptoms, consult a healthcare professional for further advice.
