Ibuprofen and paracetamol sit side by side in almost every medicine cabinet, and
they are often treated as interchangeable. They are not. They work in different 
ways, suit different kinds of pain, and carry different risks. Knowing the difference
helps you pick the right one, and avoid the wrong one if you have certain health
conditions.

## How they differ

**Ibuprofen** (sold as Advil, Motrin, Nurofen and generics) is a non-steroidal anti-
inflammatory drug, or NSAID. It relieves pain, lowers fever and reduces inflammation.**
Paracetamol** (acetaminophen, Tylenol and others) relieves pain and lowers fever
but has little anti-inflammatory effect. Because it is not an NSAID, it is gentler
on the stomach, but it is processed by the liver, which is why dose limits matter.
See our full guide to [paracetamol dosage, safety and common mistakes](https://nohas.es/paracetamol-acetaminophen-dosage-safety/).

## Which one for which problem

 | Situation | Often considered first | 
 | Pain with inflammation: sprains, muscle or joint aches, period pain, dental pain | Ibuprofen, if it is safe for you | 
 | Headache, general aches, fever | Either | 
 | History of stomach ulcers, asthma triggered by NSAIDs, kidney or heart problems | Paracetamol, after checking with a pharmacist | 
 | Pregnancy | Paracetamol is usually preferred; ask a doctor or pharmacist |

These are general starting points, not rules. Your own history and other medicines
matter more than any table.

## Ibuprofen: usual adult dosing

The NHS gives these over-the-counter guidelines for adults, but always follow your
product’s leaflet:

 * **200 mg tablets or capsules:** one or two at a time, up to three times a day
   if needed, at least four hours apart. No more than six in 24 hours.
 * **400 mg tablets or capsules:** one at a time, up to three times a day, at least
   four hours apart. No more than three tablets in 24 hours.
 * **Gels and sprays:** apply to the painful area, up to three or four times a day.
 * Take tablets with or after food, and do not use them for more than 10 days unless
   a doctor advises it.
 * Use the smallest dose for the shortest time, because risk rises with higher doses
   and longer use.

For paracetamol limits, see the paracetamol guide linked above. The limits for each
medicine apply separately.

## Who should avoid or be careful with each

**Ibuprofen: ask a pharmacist or doctor first if you:**

 * Have or have had a stomach ulcer or stomach bleeding.
 * Have asthma or allergies, or have reacted to aspirin or another NSAID.
 * Have heart, liver or kidney disease, a clotting problem or have had a stroke.
 * Are pregnant, trying to conceive or breastfeeding.
 * Have chickenpox.
 * Take blood thinners such as warfarin, steroids, some antidepressants or blood
   pressure medicines.
 * Take another NSAID such as naproxen or aspirin. Do not combine NSAIDs.

**Paracetamol: ask first if you** have liver disease, drink heavily, weigh very 
little or take other medicines that affect the liver. Be careful not to double up
with cold and flu products that already contain paracetamol.

## Can you take them together?

Because they work differently and do not directly interact, many pharmacists say
that ibuprofen and paracetamol can be taken together or alternated for short periods,
as long as each stays within its own dose limits and you are not in a group that
should avoid ibuprofen. Check with a pharmacist if you are unsure, especially if
you are older, pregnant, or have stomach, kidney, heart or asthma problems. Keep
a written note of what you took and when, so you do not lose track.

## Warning signs: stop and get medical advice

 * Black or bloody stools, vomiting blood, or severe stomach pain after ibuprofen.
 * Wheezing, swelling of the face or lips, or a rash, which may signal an allergic
   reaction. Seek emergency help for severe symptoms.
 * Pain that gets worse, or lasts beyond a few days of treatment.
 * Fever lasting about three days or more.
 * Any suspected overdose of either medicine. Contact emergency services or poison
   control immediately.

**Key takeaways**

 * Ibuprofen reduces inflammation; paracetamol does not.
 * Ibuprofen carries stomach, kidney and heart risks for some people; paracetamol’s
   main risk is liver harm if the limit is exceeded.
 * Use the lowest dose for the shortest time, and do not exceed the label limit 
   of either.
 * Do not combine ibuprofen with other NSAIDs.
 * When in doubt, ask a pharmacist, especially with other medicines or health conditions.

## Frequently asked questions

### Which works faster?

Both usually start to work within about 30 to 60 minutes when taken by mouth. Individual
response varies.

### Which is safer for the stomach?

Paracetamol is less likely to irritate the stomach. Taking ibuprofen with or after
food can reduce stomach upset.

### Which is better for a fever?

Both reduce fever. The choice usually depends on your health conditions, age and
what you have at home. For children, use only a children’s product and follow the
label and professional advice.

### Can I use ibuprofen gel instead of tablets?

Gels deliver less of the drug into the bloodstream and can be useful for localized
joint or muscle pain, but the same cautions about allergies and NSAIDs apply. Follow
the leaflet.
