Naproxen Dose

Always take Naproxen exactly as instructed by your doctor. Read the patient information leaflet thoroughly before you start taking it. Speak to your doctor or pharmacist if you are not sure of how to use Naproxen.

To make sure you don't suffer a stomach upset, Naproxen should be taken either with or after a meal.

Naproxen tablets should be swallowed whole with a drink of water. Do not crush or chew the tablets.

The dosage you require will depend on the kind of pain you are taking Naproxen for, as well as your age and whether you have any pre-existing conditions. The usual doses are:

  • Gout pain: 750mg, then 250mg every 8 hours until the pain is gone
  • For arthritis pain relief: 500mg to 1,000mg each day in either 1 or 2 doses
  • Muscle/bone pain and period pain: 500mg to start with, then 250mg every 6 to 8 hours when needed

For elderly people, or people who have liver, kidney or heart problems, these doses will normally be lower.

For children, your doctor will base the recommended dose on their weight.

For period pain

On the first day of taking Naproxen, you should take 2 tablets as soon as the pain starts. If this dose is not sufficient, you can take 1 more tablet 6 to 8 hours later.

On the second day and the following days, the dose is 1 tablet every 6 to 8 hours if you need it.

Do not take more than 3 tablets in the same 24 hours for period pain.

What if I take more than I am supposed to?

Contact your doctor immediately if you have taken too many Naproxen tablets. Taking too much of this medicine may cause common side effects.

What if I forget to take it?

If you forget to take Naproxen, just take it as soon as you remember, unless it is almost time for your next scheduled dose.

If it is nearly time for your next dose, just skip the dose you missed and continue to take Naproxen as usual.

Never double dose any medicine in an attempt to make up for missing a previous one.

Try to be consistent in taking this medicine at the same time each day, to remind you to take it. Some people find it helpful to set an alarm as a reminder to take it.

Naproxen FAQ's

Can you buy Naproxen over the counter?


Yes, Naproxen is available over the counter in a lower dose, typically anything below 250mg can be purchased over the counter. The higher dosages of naproxen, 250mg and above can not be purchased over the counter and instead will need a valid UK prescription.

Is Naproxen 500mg a strong painkiller?


Yes, this dose of Naproxen is a prescription-strength painkiller, meaning it is stronger than over-the-counter painkillers, such as ibuprofen or paracetamol. Your doctor will prescribe you Naproxen 500mg if they deem it necessary to relieve your pain.

Is it okay to use Naproxen every day?


It is recommended to online use Naproxen on a short term basis. When taken over a long period of time, or in large doses, Naproxen can cause an ulcer in your stomach or gut. There is also a risk of kidney failure and/or heart failure. To prevent these risks, you should do your best to consume the lowest possible dose, for the shortest period of time possible.

When will I feel better?


After taking naproxen, you should start to feel better within one hour. However, if you take this medication regularly twice a day, it may take up to 3 days for it to work effectively.

How long will I take naproxen for?


You may only need to take this medicine for a short period of time. The length of time you are required to use Naprosyn EC for will depend on the condition you are taking it for. For example, if you are taking it for period pain, you will only need to use it for a short time. Your doctor will instruct you on how long you should use it.

Can I take naproxen for a long time?


When taken over a long period or in large doses, this medicine may cause stomach or gut ulcers. There is also a risk of heart or kidney failure. Ideally, you should take the lowest dose possible, for the shortest time possible.

Is naproxen addictive?


There is no evidence to suggest that this nonsteroidal anti-inflammatory drug is addictive, although you should still only take it as instructed by your doctor.

Are there any other painkillers I can try?


Naproxen 250mg and 500mg tablets do not work for all types of pain. You may require a different dosage or a new medication altogether. Various painkillers exist to try for different types of conditions. However, you should not switch medicines without speaking to your doctor or pharmacist first. They will be able to prescribe a different medicine for you to buy as an alternative to Naproxen.

Why do I need to be careful of stomach ulcers?


If taken in large doses or for a long period of time, naproxen medications can cause stomach or gut ulcers. You may be advised to not use this medicine if you already have a stomach ulcer, or have had one previously. If a naproxen medicine is vital for you but comes with the risk of a stomach ulcer, you might be prescribed a second medicine such as Omeprazole or Lansoprazole to take at the same time to help lessen the risk.

Can naproxen cause heart failure?


Although the risk of this problem is very small, it has been suggested that anti-inflammatory medicines like naproxen can increase the risk of heart failure. If you are taking higher doses than you are supposed to, or you find that you need to take naproxen on a regular basis, you should speak to your doctor. They may wish to find out more about the pain you are experiencing.

Does naproxen cause kidney failure?


If you have any kidney problems, you must make sure you inform your doctor or pharmacist before you start taking naproxen. NSAIDs might cause an increased risk of sudden kidney failure and kidney damage over a period of time.

Will it affect my fertility?
