Additional Common Questions

Does naproxen make you sleepy?

Feeling sleepy is a common side effect of naproxen. You may you feel drowsy, tired or dizzy. Avoid driving, using machinery or doing other tasks that require concentration until you know how this medication affects you. Talk to your healthcare provider if you’re concerned about sleepiness or other side effects.

How much naproxen is safe?

Your healthcare provider is the best person to tell you how much naproxen is safe for you. That’s because the amount can change depending on your age and underlying medical conditions. For example, people with conditions like cardiovascular disease, stomach/upper GI ulcers or chronic kidney disease have an increased risk of adverse effects from taking naproxen. So, they should proceed with caution under a provider’s guidance and start with the lowest effective dose.

Remember that just because a medication is available without a prescription doesn’t mean it’s safe for you — in any amount. It’s always a good idea to talk to your provider before taking any new medications, including over-the-counter drugs like naproxen. Your provider will make sure the medication is safe for you based on your medical conditions and other medications you’re taking. They’ll also tell you the dosage that’s appropriate for you and how long you should take naproxen. 

Can you take Tylenol with naproxen?

You shouldn’t take a dose of both medications at the same time. However, if your provider says it’s OK, you may alternate between taking naproxen and acetaminophen (such as Tylenol®, a common acetaminophen brand).

Be sure to talk to your healthcare provider before trying this approach. Ask them:

  • Is it safe for me to alternate between naproxen and acetaminophen?
  • How soon after taking a dose of one medication can I take a dose of the other? 
  • How long can I follow this approach?
  • What side effects should I look out for?
  • When should I call you?

How long does naproxen take to kick in?

People typically start noticing improvements in symptoms about one hour after taking naproxen. You may need to take naproxen twice a day for up to three days to feel better. Your provider can tell you more about what to expect in your individual situation.

Is naproxen a narcotic?

No, naproxen isn’t part of the opioids (narcotics) class of medications. It’s a nonsteroidal anti-inflammatory drug (NSAID). 

Opioids and NSAIDs are two separate classes of medications. But they both fall under the larger umbrella of analgesics, which are medications that relieve pain. Opioids work by changing your brain’s perception of pain. NSAIDs, like naproxen, work by reducing inflammation in the area where your pain occurs.

A note from Cleveland Clinic

Naproxen can help relieve your symptoms and allow you to get back to doing the things you love. However, all medications come with risks. It’s important to talk to your healthcare provider about the risks of taking naproxen in your unique situation. Be sure to tell them about other medications you’re taking. These include prescription medications, over-the-counter drugs and herbal supplements. They’ll make sure you can safely take naproxen alongside them.

You should also talk to your provider if you have any questions or concerns about your medication schedule. Taking medications for multiple conditions can sometimes feel overwhelming. Your provider can make sure you have a safe schedule in place and help you stay organized.
