When you need quick relief from a headache, sore muscles, or a fever, you probably reach for a familiar bottle from the pharmacy. Motrin is the brand name most Australians recognize for Ibuprofen, a non‑steroidal anti‑inflammatory drug (NSAID) that reduces inflammation and pain. But Motrin isn’t the only option on the shelf, and choosing the right one depends on how fast you need relief, how long it should last, and what side‑effects you can tolerate.
What makes Motrin (Ibuprofen) different?
Motrin contains Ibuprofen, a propionic‑acid class NSAID that blocks the enzyme cyclo‑oxygenase (COX‑1 and COX‑2). This blockage stops the body from making prostaglandins, the chemicals that cause pain, fever, and swelling. In practice, you’ll feel the pain start to subside within 30‑60 minutes, and the effect can last 4‑6 hours.
- Typical adult dose: 200‑400 mg every 4-6 hours (max 1200 mg OTC)
- Onset of relief: 30‑60 minutes
- Duration: 4‑6 hours
- Common side‑effects: stomach upset, heartburn, slight headache
- Major cautions: avoid if you have severe ulcer disease, kidney problems, or are taking blood thinners
Common over‑the‑counter alternatives
Here’s a quick look at the most widely used alternatives you’ll find in Australian pharmacies.
- Acetaminophen (brand: Panadol, Tylenol) - pain reliever and fever reducer that works in the brain, not the inflammation pathway.
- Aspirin - another NSAID that also thins blood, useful for heart‑attack prevention but harsher on the stomach.
- Naproxen (brand: Naprosyn, Aleve) - longer‑acting NSAID; takes longer to feel the effect but can last up to 12 hours.
- Diclofenac (brand: Voltaren) - topical gels or oral tablets, good for joint pain with lower systemic exposure.
- Celecoxib (brand: Celebrex) - a COX‑2 selective NSAID that spares the stomach but may raise cardiovascular risk.

When to choose Motrin over the others
If you need a fast‑acting painkiller that also tackles inflammation-think sprained ankle, menstrual cramps, or dental pain-Motrin is usually the first pick. Its middle‑range cost, wide availability, and proven safety record for short‑term use make it a solid default.
- Quick onset: Works within an hour, faster than acetaminophen for most people.
- Anti‑inflammatory edge: Only NSAIDs (Ibuprofen, Naproxen, Aspirin, Diclofenac, Celecoxib) reduce swelling; acetaminophen does not.
- Balanced dosing: The 200‑400 mg dose is easy to remember and fits well with other OTC meds.
But if you have a sensitive stomach, a history of ulcers, or you’re on blood thinners, you might skip Motrin and look at a gentler option.
Scenarios where an alternative shines
Acetaminophen shines when you need fever control without stressing the stomach or when you’re pregnant (most guidelines list it as safer than NSAIDs).
Aspirin is the go‑to for low‑dose heart‑attack prevention, but for regular pain relief its higher bleeding risk makes it less attractive than Ibuprofen.
Naproxen is worth considering for chronic joint pain (e.g., osteoarthritis) because you only need to dose twice a day, reducing the chance of missed doses.
Diclofenac gel works well for localized knee or shoulder pain when you want to avoid systemic side‑effects altogether.
Celecoxib can be prescribed for patients who need strong NSAID action but have a history of gastric ulcers-its COX‑2 selectivity spares the stomach lining.
Safety tips and interactions
Regardless of the brand, keep these rules in mind:
- Never exceed the maximum daily dose listed on the pack.
- Take the tablet with food or milk to protect the stomach.
- Avoid alcohol while using NSAIDs; it raises the risk of bleeding.
- Check for interactions with blood‑pressure meds, anticoagulants, or diabetes drugs.
- If you’re under 12 years old, stick to pediatric‑specific formulations-adult doses can be dangerous.
When in doubt, a quick chat with your pharmacist can clear up confusion about which product fits your health profile.
Quick takeaways
- Motrin (Ibuprofen) offers fast pain relief and anti‑inflammatory action for most short‑term needs.
- Acetaminophen is gentler on the stomach and safer during pregnancy, but it doesn’t reduce swelling.
- Aspirin adds blood‑thinning benefits but has the highest gastrointestinal risk.
- Naproxen lasts longer, making it handy for chronic aches.
- Diclofenac gel provides local relief with minimal systemic exposure.
- Celecoxib is a prescription‑only COX‑2 option for ulcer‑prone patients, with a cardiovascular trade‑off.
Frequently Asked Questions
Can I take Motrin and acetaminophen together?
Yes, you can stagger the two drugs because they work via different pathways. Many doctors suggest alternating 200 mg ibuprofen with 500 mg acetaminophen every 3 hours for severe pain, but keep total daily limits in check.
Is Motrin safe for children?
Ibuprofen is approved for kids over 6 months when given at the pediatric dose (5‑10 mg/kg). Always use the liquid formulation with the correct measuring device.
Why does my stomach hurt after taking ibuprofen?
Ibuprofen reduces protective prostaglandins in the stomach lining, which can cause irritation or ulcers, especially with high doses or when taken on an empty stomach.
Which OTC painkiller is best for menstrual cramps?
Most women find ibuprofen or naproxen most effective because both address pain and the inflammation that often accompanies cramps. Acetaminophen works for pain but not for the swelling.
Can I use diclofenac gel if I’m allergic to aspirin?
Allergies to aspirin don’t automatically mean a reaction to diclofenac, but both are NSAIDs. If you’ve had a severe reaction, talk to a pharmacist before using any NSAID.
Does ibuprofen increase blood pressure?
Long‑term high‑dose NSAID use can raise blood pressure and reduce kidney function. Short‑term OTC use at recommended doses usually has minimal impact, but monitor if you already have hypertension.
Picking the right painkiller isn’t a one‑size‑fits‑all decision. By weighing onset time, duration, side‑effects, and personal health factors, you can match the drug to the job and stay comfortable without unnecessary risks.

October 21, 2025 At 14:48While many consider an over‑the‑counter analgesic guide to be merely utilitarian, the subtle pharmacodynamic differences between Motrin and its counterparts deserve a discerning palate. The elegance of ibuprofen’s COX inhibition, paired with its rapid onset, offers a refined solution for acute inflammation. In the grand tapestry of pain management, choosing the appropriate agent is an art as much as a science.
