How long should Motrin (ibuprofen) and Tylenol (acetaminophen) be taken after a hysterectomy?

Duration of Motrin and Tylenol After Hysterectomy

You should take acetaminophen (Tylenol) 1000 mg every 6 hours and ibuprofen (Motrin) 600-800 mg every 6 hours for at least 48-72 hours after hysterectomy, then transition to as-needed dosing based on your pain level. 1

Recommended Treatment Duration and Dosing

Initial 48-72 Hour Period (Scheduled Dosing)

• Acetaminophen: Take 1000 mg orally or intravenously every 6 hours for the first 72 hours postoperatively 1
• Ibuprofen: Take 600-800 mg every 6 hours during this same period 2, 3
• Scheduled dosing is superior to as-needed dosing during this critical early recovery phase 1, 4

The American College of Obstetricians and Gynecologists specifically recommends this 48-72 hour minimum duration because this is when pain is most severe and when establishing good pain control prevents both acute suffering and reduces the risk of persistent pain 2, 1.

After 72 Hours (Transition Phase)

• Transition to as-needed dosing based on your individual pain level after the initial 72-hour period 1, 4
• Continue the combination therapy (both medications together) rather than using either alone, as the combination is more effective 1
• Most patients can discontinue or significantly reduce usage within 5-7 days post-surgery, though individual recovery varies 2

Why This Combination and Duration Matters

Evidence for Combination Therapy

The combination of acetaminophen plus an NSAID like ibuprofen is more effective than either medication alone 1. Research demonstrates that:

• Acetaminophen reduces overall narcotic consumption and improves patient satisfaction 1
• Ibuprofen IV 800 mg every 6 hours decreases morphine requirements by 19% and reduces pain scores significantly 3
• Patients receiving this combination have shorter hospital stays and fewer opioid-related complications 2, 1

Impact on Long-Term Outcomes

Starting acetaminophen at surgery and continuing for 72 hours has been shown to reduce persistent incisional pain at 3 months after hysterectomy 5. In one study, 89% of acetaminophen-treated patients had no pain at 3 months compared to only 66% in the placebo group 5. This underscores the importance of not just taking these medications, but taking them for the full recommended duration.

Critical Safety Considerations

When to Avoid or Use Caution with NSAIDs (Motrin/Ibuprofen)

Absolute contraindications - do not take ibuprofen if you have: 1

• Active peptic ulcer disease or history of gastrointestinal bleeding
• Severe kidney or liver disease
• Known allergy to NSAIDs or aspirin
• Heart failure or recent heart attack
• Third trimester of pregnancy

Use with caution if you: 1, 6

• Are over 65 years old
• Have hypertension or cardiovascular disease
• Take blood thinners or corticosteroids
• Have a history of stomach ulcers

Acetaminophen Safety

• Maximum daily dose is 4000 mg (four 1000 mg doses) 4
• Use caution if you have pre-existing liver disease 2, 4
• Monitor for signs of liver problems if you have risk factors 2

Common Pitfalls to Avoid

Don't Rely Solely on Narcotics

Narcotics increase sedation without providing superior pain control compared to this multimodal non-narcotic regimen 1. The evidence shows that preemptive and scheduled use of acetaminophen and NSAIDs actually reduces your need for narcotics and their associated side effects 2.

Don't Wait Until Pain is Severe

Taking these medications on a scheduled basis (every 6 hours around the clock) for the first 48-72 hours is more effective than waiting until you feel pain 1, 4. This approach maintains steady blood levels and prevents pain from escalating.

Don't Stop Too Early

Stopping before 48 hours may compromise your pain control and potentially increase your risk of developing persistent pain 1, 5. The full 72-hour course provides optimal benefit for both immediate comfort and long-term outcomes.

Additional Considerations

If You Have High Risk for Nausea/Vomiting

Request phenothiazine medication (such as prochlorperazine or promethazine) in addition to your pain regimen 1. Phenothiazines are the only preemptive medications proven to reduce postoperative nausea and vomiting 2, 1.

Monitoring Your Response

• Pain should steadily improve over the first week 2
• If pain worsens or doesn't improve after 3-4 days, contact your surgeon 2
• Most patients can transition to as-needed dosing by day 4-5, using the medications only when discomfort interferes with activities 1, 4
