What is Naproxen?

Naproxen is a non-steroidal anti-inflammatory drug (NSAID) which is used to provide pain relief for a variety of conditions ranging from arthritis to Gout.

You can buy Naproxen online at Medicine Direct, following an online consultation with a certified doctor, who will prescribe Naproxen if you they deem it a suitable treatment for your condition.

It is available to buy in packets of 56 tablets or 112 tablets, in doses of Naproxen 250 mg or Naproxen 500 mg.

If you order before 2pm, we can offer you next day delivery on your medication.

What is Naproxen used to treat?

Naproxen is used to treat a range of different conditions, providing pain relief for period pain, arthritis, muscle/joint pain and back pain.

Like most anti-inflammatory drugs, it works by reducing the hormones in your body that cause pain and inflammation.

In most cases, paracetamol is the most effective pain relief medicine, but taking Naproxen for conditions like period pain or back pain is more effective.

It is also safe for children when taken under medical supervision to treat the following:

  • Period pain for girls of any age
  • Diseases of the joints in children aged 2 years old and over
  • Muscle and bone disorders in babies who are older than 1 month

Who can take Naproxen?

Naproxen may not be a suitable pain relief medicine for everyone.

Naproxen is not suitable for you if you have any of the below:

  • You are in the late stages of pregnancy
  • You have had bleeding or perforation in your stomach while previously taking a non-steroidal anti-inflammatory drug (NSAID)
  • You have severe liver, kidney, or heart problems
  • You have ever had, or currently have, any stomach problems, such as an ulcer or bleeding

If any of the following conditions apply to you, you should make sure you tell your doctor before you start taking Naproxen tablets:

  • You have any kidney or liver problems
  • You have any problems with blood clotting
  • You have lumps in your nose (polyps), you sneeze a lot, have a runny, blocked, or itchy nose
  • You are an elderly person
  • You have asthma
  • You have any allergies, such as hay fever, or have had swelling of the face, lips, eyes, or tongue in the past
  • You feel weak
  • You have high levels of fat in your blood
  • You are a smoker
  • You have high blood pressure
  • You have diabetes
  • You suffer from any autoimmune conditions
  • You have problems with blood vessels anywhere in your body

Seek a doctor's guidance if you are not sure whether Naproxen is a suitable treatment for you.

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?

You can only buy Naproxen when you have a prescription from a doctor. At Medicine Direct, you can buy Naproxen from our online pharmacy, following an online consultation with a certified doctor. After assessing your symptoms, one of our doctors will prescribe Naproxen if they believe it to be a suitable pain relief medicine for you.

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?

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.

What's the difference between Naproxen and other pain treatments?

Naproxen 500mg tablets are a prescription-strength anti-inflammatory drug, making them stronger than painkillers you can purchase over the counter, such as paracetamol. It is also believed to have a decreased risk of adverse effects. Because Naproxen is an anti-inflammatory, it is a more effective pain relief for conditions that cause inflammation, such as painful periods or back pain.

How long does it take to work?

You should start to feel better within one hour of taking this medication. However, if taken twice a day, it may take up to 3 days for Naproxen to work properly. If your pain does not improve after 3 days, speak to your doctor for advice.

Will Naproxen affect my driving?

Naproxen can cause changes in vision or dizziness. If you experience either of these effects when you use this medicine, you should not drive, ride a bike, or operate machinery until you feel better.

Can you get high from taking Naproxen?

No, Naproxen does not get you high

What should not be taken with Naproxen?

Certain medicines may interact with Naproxen. For a list of medications you should not combine with Naproxen, please refer to the Warnings and Drug Interactions tab on this page.

Common side effects of Naproxen include:

  • Feeling confused
  • Headaches
  • Ringing of the ears
  • Changes in vision
  • Feeling sleepy or tired

  • Stroke (muscle weakness and numbness, altered sense of taste, smell, hearing, vision, or confusion)
  • Heart attack (chest pain that may spread to your left arm, neck and shoulders)
  • Blood in your urine, a decrease in how much you urinate, or feeling or being sick (could be kidney damage or an infection)
  • Heartburn, severe indigestion, stomach pain, nausea or vomiting

  • Ulcers or holes form in your stomach (symptoms may include stomach pain, feeling sick, vomiting, or a fever)

Consistent use of Naproxen will wear away the stomach lining and can lead to Gastritis. When taking naproxen, it is recommended to take a Proton Pump Inhibitor (PPI's) such as Omeprazole or Lansoprazole to give the stomach a layer of protection and reduce and excess stomach acid caused as a result of naproxen consumption.

Liver problems

  • Yellowing of your skin or the whites of your eyes turn yellow
  • Tiredness
  • Loss of appetite
  • Feeling or being sick
  • Pale stools
  • Problems shown in blood tests

  • You have tightness in the chest or throat
  • You have a skin rash that is red, itchy, swollen, blistered or peeling skin
  • You have swelling in your face, throat, lips, tongue, or mouth
  • You are finding it hard to breathe or speak

Always read the patient information leaflet for a comprehensive list of potential side effects you may suffer.

If you have any questions or concerns at all, please do not hesitate to discuss them with your doctor.

Naproxen Warnings and drug interactions

If you are taking Naproxen on a consistent basis, it is highly recommended to also take Omeprazole to ease the symptoms of acid reflux/heartburn, which is a side effect when taking Naproxen. Other Proton Pump Inhibitors that can be taken include Lansoprazole which will also provide effective relief from acid related symptoms.

PPI's also offer a layer of protection to the lining of the stomach and can help with long term side effects such as gastritis.

Naproxen may interact with other medicines you are taking at the same time, which can hinder its effectiveness and increase your risk of experiencing adverse effects.

Before you take Naproxen, you should always inform your doctor and pharmacist of any other medications you are already taking. This includes both prescription and non-prescription medication, herbal remedies, vitamins and supplements.

In particular, your doctor should be aware if you are currently taking any of the following medicines:

  • Any other NSAID's (nonsteroidal anti-inflammatory drug)
  • Any medications used for heart problems
  • Any medications for high blood pressure
  • Any medicines for arthritis treatment, such as methotrexate
  • Any steroids
  • Any blood thinning medicines, such as warfarin
  • Any medicines that make you urinate more frequently (diuretics)
  • Any antidepressants

If you have any questions as to whether Naproxen is suitable for you to use, please talk to your pharmacist before you start using it.

Never order any medicine online unless it is from a pharmacy that is registered with the General Pharmaceutical Council, like Medicine Direct.
