Motrin Dosage by Condition
Pain Relief and Fever
For mild to moderate pain or fever, adults typically take 200 to 400 mg of Motrin every 4 to 6 hours as needed. Do not exceed 3200 mg in 24 hours. For children, dosing depends on weight, usually 10 mg per kilogram of body weight every 6 to 8 hours.
Inflammatory Conditions (e.g., Arthritis)
In cases of arthritis or other inflammatory conditions, adults may require higher doses, often 400 to 800 mg every 6 to 8 hours. However, these doses should be taken under medical supervision to avoid side effects. Children rarely require Motrin for chronic inflammatory conditions without a doctor's guidance.
Postoperative Pain
After surgery, Motrin can be used to manage pain. Adults should follow prescribed doses, often 400 mg every 4 to 6 hours. Children’s doses again depend on weight and should be carefully monitored.
What is the Typical Motrin Dose for Adults?
Adults generally take Motrin in doses ranging from 200 mg to 800 mg per dose. The medication can be taken every 6 to 8 hours, but it’s important not to exceed 3200 mg in a 24-hour period to reduce the risk of side effects like gastrointestinal irritation or kidney problems.
For occasional pain or fever, 200 to 400 mg every 4 to 6 hours is common. For chronic conditions such as arthritis, higher doses may be prescribed, but always under medical supervision.
What is the Typical Motrin Dose for Children?
Children’s dosing is weight-based to ensure safety and effectiveness. The general guideline is 10 mg of ibuprofen per kilogram of body weight per dose, given every 6 to 8 hours. The maximum daily dose should not exceed 40 mg/kg, with a typical maximum of 1200 mg per day.
For example, a child weighing 20 kg (about 44 pounds) might take 200 mg per dose, up to three or four times a day. Always use the measuring device provided with the liquid suspension to ensure accurate dosing.
What to Do If You Miss a Dose of Motrin?
If you miss a dose of Motrin, take it as soon as you remember. However, if it’s almost time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not double up doses to make up for the missed one, as this can increase the risk of side effects.
How to Adjust Your Motrin Dose for Certain Medical Conditions
Kidney or Liver Issues
People with kidney or liver problems should consult a healthcare professional before taking Motrin. Dosage adjustments or alternative medications may be necessary to avoid worsening these conditions.
Gastrointestinal Disorders
If you have a history of ulcers or gastrointestinal bleeding, use Motrin cautiously. Taking it with food or milk can help minimize stomach irritation, but your doctor may recommend a lower dose or a different pain reliever.

Always follow dosing instructions carefully and consult a healthcare provider if unsure about the correct amount.
Tips for Taking Motrin Safely
Take Motrin with food or milk to reduce stomach upset.
Do not exceed the recommended dose or frequency.
