Quick Answer: For period cramps, an NSAID such as Advil (ibuprofen) is usually the better choice. NSAIDs lower the prostaglandins that cause uterine cramping, and ACOG lists them as a first-line treatment; starting at the first sign of your period works best. Midol Complete contains acetaminophen 500 mg, caffeine 60 mg and pyrilamine 15 mg per caplet. Acetaminophen relieves pain but doesn’t reduce prostaglandins much, so it’s often less effective for cramps; the caffeine and antihistamine target bloating and fatigue. Midol Complete is a good option if you can’t take NSAIDs (ulcers, kidney disease, aspirin allergy, some asthma). The Midol brand also sells ibuprofen and naproxen products, so check the label.
Midol vs Advil at a Glance

| Labeled for | Cramps, bloating, water-weight gain, headache, backache, muscle aches, fatigue (menstrual) | Menstrual cramps, headache, backache, muscle aches, toothache, arthritis, fever |
| Dose (12+) | 2 caplets with water every 6 h as needed | 1 tablet every 4–6 h; may use 2 |
| Daily max | 6 caplets (3,000 mg acetaminophen) | 6 tablets (1,200 mg) unless a doctor directs |

Why Periods Cramp, and Why That Matters for the Choice
Before and during menstruation, the uterine lining releases prostaglandins, chemicals that make the uterus contract. Higher levels mean stronger, more painful cramps, and prostaglandins spilling into the bloodstream can also cause nausea, diarrhea and headache. Drugs that block prostaglandin production (NSAIDs such as ibuprofen and naproxen) treat the cause. Acetaminophen mainly works in the brain and is weaker at reducing prostaglandins in the body, so it’s often less effective for cramps.
What the Evidence Says
- NSAIDs: A Cochrane review of NSAIDs for primary dysmenorrhea found they are clearly more effective than placebo and appeared more effective than acetaminophen, with no single NSAID clearly better than another. ACOG lists NSAIDs as a first-line treatment for painful periods.
- Acetaminophen: Helps some people and is better than nothing, but on average gives less cramp relief than an NSAID.
- Caffeine: Adds a modest boost to pain relievers in headache studies, which is why it shows up in combination products.
- Pyrilamine: An older antihistamine included for bloating/water weight; evidence for that use is limited, and it can cause drowsiness.
Not All Midol Is the Same
“Midol” is a brand, not an ingredient. Midol Complete is the acetaminophen-caffeine-pyrilamine product compared here, and there’s also a caffeine-free version. Other Midol products contain ibuprofen or naproxen, which act like Advil or Aleve. Always read the active ingredients on the Drug Facts panel, and never take two products with the same ingredient. For naproxen, see Aleve vs Advil.
How to Use Advil for Cramps
Timing matters more than most people realize. Taking an NSAID at the first sign of your period (or the day before, if your cycle is predictable) and continuing on a regular schedule for the first 1–2 days blocks prostaglandins before they build up. Take it with food or milk if it upsets your stomach. Stay within the label: 1–2 tablets every 4–6 hours, no more than 6 in 24 hours unless a doctor directs. Advil Menstrual Pain uses ibuprofen sodium for faster absorption, but the active drug is the same.
Safety
Midol Complete
- Liver: More than 6 caplets in 24 hours, use with other acetaminophen products (many cold medicines and Tylenol), or 3+ alcoholic drinks a day can cause severe liver damage.
- Drowsiness: Pyrilamine can make you sleepy; be careful driving and avoid alcohol and sedatives.
- Caffeine: Each dose has about as much as a cup of coffee; limit other caffeine to avoid jitters, insomnia or a racing heart.
- Ask a doctor first if you have liver disease, glaucoma, breathing problems such as emphysema or chronic bronchitis, or take warfarin.
Advil
- Stomach: Bleeding risk rises with age 60+, prior ulcers, blood thinners or steroids, other NSAIDs, or 3+ drinks a day.
- Heart, kidneys, blood pressure: NSAIDs can raise these risks, especially at high doses or with long use.
- Asthma: some people with asthma react to NSAIDs or aspirin.
- Pregnancy: avoid NSAIDs at 20 weeks or later unless a doctor directs.
Can You Take Midol Complete and Advil Together?
They contain different drugs (acetaminophen vs ibuprofen), and clinicians sometimes alternate or combine acetaminophen and ibuprofen for pain, each within its own daily limit. Check with a pharmacist first, especially because Midol Complete also contains caffeine and an antihistamine. Never combine Advil with an ibuprofen- or naproxen-based Midol.
Beyond Pills
Heat (a heating pad or patch) has evidence comparable to NSAIDs in small trials, and regular exercise helps some people. Hormonal birth control is a common next step for cramps that don’t respond to NSAIDs. Our period cramps relief guide covers more options, and our heavy periods guide explains when bleeding is too much.
Who Should Choose What
- Cramps are the main problem: Advil (or another NSAID), started early.
- Can’t take NSAIDs: Midol Complete (or plain acetaminophen) plus heat.
- Bloating and fatigue bother you more than cramps: Midol Complete may feel more helpful, but watch the caffeine and drowsiness.
- Pain is severe, getting worse each year, or not helped by NSAIDs: see a gynecologist to check for endometriosis, fibroids or adenomyosis.
When to Talk to Your Doctor or Pharmacist
- Cramps are severe enough to miss school or work, or don’t improve with an NSAID taken as directed.
- Pain started or got much worse after age 25, or comes with pain during sex, between periods or with bowel movements (possible endometriosis or fibroids).
- Very heavy bleeding (soaking a pad or tampon every hour for several hours), large clots, or signs of anemia.
- Fever, unusual discharge, or pelvic pain that isn’t cyclical.
- You have liver, kidney or heart disease, ulcers, asthma, take blood thinners, or might be pregnant.
Frequently Asked Questions
Is Midol or Advil better for cramps?
For most people, Advil (ibuprofen) is better for cramps because NSAIDs block the prostaglandins that cause uterine contractions, and ACOG lists them as first-line. Midol Complete relies on acetaminophen, which is generally less effective for cramps, plus caffeine and an antihistamine for bloating and fatigue.
What is in Midol Complete?
Each Midol Complete caplet contains acetaminophen 500 mg (pain reliever), caffeine 60 mg (diuretic) and pyrilamine maleate 15 mg (antihistamine). The adult dose is 2 caplets every 6 hours as needed, with no more than 6 caplets in 24 hours.
Can I take Midol and Advil together?
Midol Complete (acetaminophen) and Advil (ibuprofen) are different drugs and are sometimes used together within each one’s daily limit, but ask a pharmacist first. Never combine Advil with a Midol product that contains ibuprofen or naproxen.
Does Midol make you sleepy?
Midol Complete can, because it contains the antihistamine pyrilamine. The label warns you may get drowsy and to be careful driving. The caffeine in it may offset this for some people.
When should I take ibuprofen for period cramps?
It works best started at the first sign of your period, or just before if your cycle is predictable, and taken regularly for the first day or two as the label allows. That blocks prostaglandins before they build up.
Is Midol safe for teenagers?
Midol Complete is labeled for adults and children 12 and older; under 12, consult a doctor. Teens should stay within the 6-caplet daily limit and avoid other acetaminophen products at the same time.
