Ibuprofen, the active ingredient in Motrin, comes in various strengths depending on the product. Whether you’re using over-the-counter (OTC) or prescription Motrin, knowing the mg per dose helps avoid mistakes. This article explains Motrin’s strengths, dosages, and safety tips in simple terms.
By the end, you’ll know exactly how many mg are in different Motrin products and how to use them responsibly. Let’s dive into the details of Motrin’s ibuprofen content and proper dosing for adults and children.
What Is Motrin?
Motrin is a brand name for ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID). It reduces pain, inflammation, and fever by blocking chemicals in the body that cause discomfort. People use it for headaches, menstrual cramps, arthritis, and more.
It’s available in multiple forms, like tablets, liquid gels, and oral suspensions. Each form contains a specific amount of ibuprofen, measured in milligrams. Knowing the mg in each product helps you choose the right dose.
Motrin comes in both OTC and prescription strengths. OTC versions are common for mild pain, while prescription doses are for more severe conditions.
Forms and Strengths of Motrin
Motrin products vary in ibuprofen content based on their form and intended use. OTC Motrin typically includes tablets, caplets, or liquid gels, while children’s versions often come as oral suspensions or chewables. Below are the common strengths available.
Over-the-Counter Motrin Strengths
Regular OTC Motrin IB tablets and caplets contain 200 mg of ibuprofen per dose. These are designed for adults and children over 12. Extra Strength Motrin (available in some regions) offers 300 mg per tablet, and Super Strength Motrin provides 400 mg per tablet.
Liquid gels, like Motrin IB Liquid Gels, also contain 200 mg or 400 mg of ibuprofen. Always check the label to confirm the strength, as it affects how many mg in Motrin you’re taking per dose.
Prescription Motrin Strengths
Prescription Motrin tablets come in higher strengths: 400 mg, 600 mg, and 800 mg. These are used for conditions like rheumatoid arthritis or severe pain. A doctor prescribes these based on your specific needs.
Higher doses require medical supervision to avoid side effects. Never use prescription-strength Motrin without a doctor’s guidance.
Children’s and Infant’s Motrin
Children’s Motrin Oral Suspension contains 100 mg of ibuprofen per 5 mL. Infant’s Motrin Drops are more concentrated, with 50 mg per 1.25 mL. Chewable tablets for kids typically have 100 mg per tablet.
Dosing for children depends on weight and age. Always use the provided dosing device for liquid forms to measure accurately.
Recommended Dosages for Adults
For OTC Motrin, the standard dose is 200–400 mg every 4–6 hours as needed. Adults should not exceed 1,200 mg per day unless directed by a doctor. Prescription doses can go up to 3,200 mg daily, split into multiple doses.
Take Motrin with food or milk to reduce stomach upset. Drinking water helps ensure the pill reaches your stomach properly.
Always use the lowest effective dose to minimize risks. If 200 mg doesn’t relieve pain, you can take 400 mg, but don’t exceed 6 tablets (1,200 mg) in 24 hours for OTC use.
Dosage for Children
Children’s Motrin dosages are based on weight and age. For kids aged 2–11, the typical dose is 5–10 mg per kg of body weight every 6–8 hours. The maximum daily dose is 40 mg per kg.
For example, a child weighing 44 lbs (20 kg) can take 100–200 mg per dose, up to 800 mg daily. Use the dosing chart on the product label or consult a pediatrician.
Infants under 6 months should not take Motrin unless prescribed by a doctor. Always measure liquid doses with the provided syringe or cup.

How to Choose the Right Dose
Choosing the correct Motrin dose depends on your condition and age. For mild pain or fever, start with 200 mg every 4–6 hours. If relief isn’t enough, increase to 400 mg per dose, staying under the daily limit.
For chronic conditions like arthritis, prescription doses (400–800 mg) may be needed multiple times daily. Always consult a doctor for long-term use.
Children’s doses require extra care. Use weight-based dosing charts and avoid giving Motrin to kids under 6 months without medical advice.
Safety Tips for Using Motrin
Motrin is effective but requires careful use to avoid side effects. Never exceed the recommended dose, as overdosing can harm your stomach or kidneys. Symptoms of overdose include nausea, dizziness, or rapid heartbeat.
Take Motrin with food to reduce stomach irritation. Avoid alcohol, as it increases the risk of stomach bleeding.
Check with a doctor if you’re pregnant, especially after 20 weeks, or have conditions like kidney disease or diabetes. Motrin can interact with medications like blood thinners or aspirin.
Side Effects and Risks
Common side effects of Motrin include stomach pain, nausea, or heartburn. These are less likely with lower doses or when taken with food.
Serious risks include stomach bleeding, kidney damage, or increased risk of heart attack or stroke with prolonged use. Older adults and those with existing health conditions are at higher risk.
Stop use and seek medical help if you notice symptoms like black stools, chest pain, or swelling. Always read the product’s warnings before use.
Special Considerations
Certain groups need extra caution with Motrin. Pregnant women should avoid it in the third trimester unless prescribed, as it may affect the baby. Breastfeeding mothers should consult a doctor.
People with liver or kidney issues may need lower doses or alternative medications. Always inform your doctor about other medications you’re taking.
Children under 12 should only use Motrin products designed for their age group. Follow pediatric dosing guidelines carefully to ensure safety.
How to Store Motrin
Store Motrin at room temperature, away from heat, moisture, and direct light. Keep it in a closed container out of children’s reach.
Don’t use expired Motrin, as it may be less effective. Dispose of unused medication safely through a pharmacy take-back program.
Check liquid suspensions for proper consistency before use. Shake well to ensure even distribution of ibuprofen.
Alternatives to Motrin
If Motrin isn’t suitable, other pain relievers like acetaminophen (Tylenol) can help with pain and fever. Acetaminophen is gentler on the stomach but doesn’t reduce inflammation.
Naproxen (Aleve) is another NSAID with longer-lasting effects but may cause more stomach upset. Always compare risks and benefits with a healthcare provider.
For children, pediatrician-approved doses of acetaminophen are often a safe alternative. Consult a doctor for personalized advice.
