What happens if you take naproxen and tylenol together

Cautions with other medicines

There are some medicines that can affect the way naproxen works.

Tell your doctor if you're taking:

  • other anti-inflammatory medicines, such as aspirin or ibuprofen
  • medicines that help to prevent blood clots, such as warfarin or rivaroxaban
  • steroids, such as prednisolone
  • medicines that make you pee more (diuretics), such as furosemide
  • medicines used to treat heart problems and high blood pressure
  • antidepressants, such as citalopram
  • medicine used to treat rheumatoid arthritis, such as methotrexate

Taking naproxen with other painkillers

Do not take naproxen with ibuprofen or other non-steroidal anti-inflammatory drugs (NSAIDs). But it's OK to take naproxen with paracetamol or co-codamol that you buy over the counter. This should just be for short periods of time.

If you often need to take extra painkillers with naproxen or for more than a few days, talk to your doctor. Sometimes, taking different painkillers together is a good way to relieve pain, but there may be other treatments you can try.

It's OK to take other painkillers with naproxen for longer if your doctor has given them to you on prescription and told you to take them together.

If you're unsure, talk to your doctor.

Mixing naproxen with herbal remedies and supplements

There's not enough information to say that complementary medicines and herbal remedies are safe to take with naproxen. They're not tested in the same way as pharmacy and prescription medicines. They're generally not tested for the effect they have on other medicines.

Medicine safety

Tell your doctor or pharmacist if you're taking any other medicines, including herbal remedies, vitamins or supplements.

What happens if you take naproxen and tylenol together

The first line of treatment for many knee and hip problems includes taking over-the-counter pain medications. Acetaminophen and non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen and naproxen are the most common pain medication options. However, these pain medications have a variety of side effects, so it's important to discuss your personal health risks with your doctor when considering long-term use for chronic conditions such as osteoarthritis.

Acetaminophen (Tylenol and other brands) is usually effective for mild pain and is easy on the stomach. However, it is toxic to the liver at high doses. The recommended maximum per day is generally set at 4 grams (4,000 milligrams), which is the equivalent of eight extra-strength Tylenol tablets. But that dosage can still cause liver problems for some people. To be safe, aim for 3,000 milligrams or less, and be cautious of mixing multiple products containing acetaminophen, such as a pain reliever and a cold medication or a prescribed narcotic.

The FDA now recommends using products containing no more than 325 milligrams per pill or capsule (the equivalent of regular-strength Tylenol rather than extra-strength) in order to avoid excessive dosages. Don't take acetaminophen if you drink more than a moderate amount of alcohol on a regular basis or if you have liver disease.

NSAIDs such as aspirin, ibuprofen (Advil, Motrin), and naproxen (Aleve, Anaprox) may be more effective than acetaminophen for certain conditions because they reduce inflammation as well as relieve pain. But NSAID medications have side effects, the most common is stomach irritation. It can also cause stomach and intestinal ulcers, which can lead to internal bleeding. You can ask your doctor about taking a stomach acid inhibitor to reduce these risks. NSAIDs also carry an increased risk of heart attack, stroke, and kidney failure when taken at high doses or for long periods of time.
Taking acetaminophen along with an NSAID may provide equivalent pain relief with lower doses of both pain medications, thus minimizing side effects. You can also alternate between the two to reduce the risk from either type of medication.

If you already have a headache and navigate your way to the pain relief shelf at your pharmacy the headache is likely to get worse. That's because there are a bazillion names on the bottles. Very complicated. But this is only because the manufacturers of analgesics want it that way. In reality, it is very simple. There are only four drugs to choose from despite all the different names (1). So people are perpetually confused about what painkiller they're looking at.

And many are also unaware that some of these drugs can be combined while others cannot. First, let's look at the four drugs that are available OTC in the US and some alternate names they are known by. The first three all belong to a class of drugs called NSAIDs (non-steroidal anti-inflammatory drugs). Tylenol does not. It works (but not very well - See Tylenol Isn't So Safe, But At Least It Works, Right?) by blocking pain signals to the brain. 

OTC PAIN RELIEVERS

1. Aspirin:

  • Acetylsalicylic acid
  • ASA
  • Excedrin (with acetaminophen and caffeine)
  • Anicin (with caffeine)
  • Bufferin (with an antacid)
  • Alka-Seltzer (with various other drugs depending on use)

2. Ibuprofen:

  • Advil
  • Motrin
  •  IBU
  • Midol IB
  • Genpril 

3. Naproxen:

  • Aleve
  • Naprosyn
  • Anaprox
  • Sodium Naproxen

4. Acetaminophen:

  • Tylenol
  • APAP
  • Paracetamol
  • Panadol

So, why does the OTC pain relief counter at CVS look like this?

It's because drug companies have combined the analgesics with other drugs, for example, antihistamines, to help with sleep or allergies, something that I think is pretty scummy and have written about in the past (See Combining Pain, Cold, Cough, And Sleep Meds - Great For Drug Companies, But Unethical)

WHICH DRUGS CAN BE COMBINED SAFELY?

So, despite all the noise, it's very simple. There are four OTC pain medications. It is safe, even helpful, to take some of them together, but not others. A new article in Medical News Today helps sort this out. Although the article speaks only about Aleve and Tylenol it also applies to Tylenol plus the other NSAIDs - aspirin, and ibuprofen. 

NSAIDs are generally safe to take with Tylenol, and the two together work better than either one alone. There are three ways to do this:

  1. Taking the NSAID and Tylenol on alternate days, especially for chronic pain, is easier on your stomach and liver than taking either or both drugs daily, but the degree of pain relief may be insufficient. 
  2. Taking the NSAID and Tylenol at the same time will give better superior pain relief than in scenario #1 but may wear off before it's time for the next dose in 4-6 hours.
  3. Alternating the two drugs, for example, the NSAID at 0,4, and 8 hours plus the Tylenol at 2,6, and 10 hours will produce a more sustained level of pain relief.

WHICH DRUGS CANNOT BE COMBINED SAFELY?

This is also simple. Aspirin, Advil, and Aleve are all NSAIDs and control pain and inflammation by a common mechanism. But they also produce side effects, most commonly heartburn, gastric bleeding, and ulcers by a common mechanism. So taking Advil plus Aleve is going to mess up your stomach or cause bleeding about the same as taking double the dose or either drug. For this reason, it is not safe to combine NSAIDs (2)

American Council friend Dr. Aric Hausknecht, a neurologist and pain management physician explains:

"OTC oral pain meds basically fall into two categories, Tylenol and NSAIDs. All NSAIDs will have a ceiling effect, i.e. taking more of that particular NSAID, or combining with a different NSAID once you have taken the maximum dose, will not produce any further analgesic effect (and will increase the likelihood of side effects). So, if one takes the maximum dose of ibuprofen, taking another NSAID or aspirin would not provide any therapeutic benefit and would increase the likelihood of ulcers. Tylenol could be taken simultaneously with a full dose of NSAID and would possibly provide synergistic pain relief."

WHAT ABOUT TOPICAL NSAIDs?

A number of creams and patches are applied directly to the skin (3) at the affected area. Since they do not go through the stomach or result in high blood levels they are safer than using two different NSAID pills. Dr. Hausknecht says:

Other OTCs include the topical compounds and patches and those could be taken in combination with a maximal dose of Tylenol or NSAIDs.

Feel better.

NOTES:

(1) There used to be five. Ketoprofen (Orudis) was sold OTC but is now by prescription only.

(2) Kidney damage is also a side effect of NSAIDS. Heart attacks are also linked to NSAID use, but less so for the OTC NSAIDs.

(3) Voltaren (diclofenac) is commonly used in a patch. 

How soon after taking naproxen can I take Tylenol?

If you need additional pain relief, you can combine aspirin, naproxen, or ibuprofen with acetaminophen. However, do not take aspirin, naproxen, or ibuprofen within 8-12 hours of each other. Also, watch out for pain medications that might be included in combination products such as those used for cough and cold.

What pain reliever can you take with naproxen?

Do not take naproxen with ibuprofen or other non-steroidal anti-inflammatory drugs (NSAIDs). But it's OK to take naproxen with paracetamol or co-codamol that you buy over the counter.
