Naprelan (Naproxen) — Patient Information (Australia)

Naprelan is a brand of naproxen made as an extended-release (also called “sustained-release”) medicine. It belongs to a group of medicines called NSAIDs (non-steroidal anti-inflammatory drugs). Naprelan is used to reduce pain, inflammation, and fever associated with a range of conditions.

This guide explains how Naprelan works, how it’s used, key safety considerations, and practical tips. If you are unsure whether Naprelan is suitable for you, speak with a pharmacist or doctor.

Quick facts

• Medicine: Naprelan (naproxen) extended-release
• Type: NSAID
• Common effects: Relieves pain and inflammation
• How it’s taken: Usually once daily (varies by strength and condition)
• Key precautions: Stomach/ulcer risk, kidney effects, cardiovascular risk, interactions with other medicines

Basic product information

Naprelan is designed to release naproxen gradually over time. This helps maintain pain relief for longer than standard immediate-release naproxen formulations.

What it looks like / strengths: Naprelan comes in different strengths depending on the product you purchase. Your pharmacy label will show the exact strength you have.

Who it suits: People who need ongoing relief from pain and inflammation, where an extended-release formulation is appropriate.

Who should avoid it unless advised: People with certain stomach ulcer histories, serious kidney disease, NSAID allergy, or other contraindications (see Safety profile below).

How Naprelan works (mechanism of action)

Naproxen works by blocking enzymes called cyclooxygenases (COX-1 and COX-2). These enzymes help produce prostaglandins, which are chemical messengers involved in:

• Pain signalling
• Inflammation and swelling
• Fever

By lowering prostaglandin production, Naprelan helps reduce pain and inflammation. Because prostaglandins also help protect the stomach lining and support kidney blood flow, NSAIDs can cause side effects in some people—especially with long-term use or high doses.

Pharmacokinetics (how the body handles Naprelan)

“Pharmacokinetics” describes what happens from the time you take a dose until the medicine is cleared from your body.

Absorption

• Naprelan is extended-release, meaning naproxen is released gradually.
• After taking a dose, blood levels rise more slowly compared with immediate-release naproxen.

Time to peak concentration

• With extended-release preparations, maximum blood levels typically occur later than with immediate-release products.
• The exact timing can vary by individual factors such as dose, food, and overall health.

Distribution

• Naproxen distributes through body tissues and is partly bound to plasma proteins.

Metabolism and elimination

• Naproxen is metabolised mainly in the liver.
• Elimination is largely through the kidneys (urine), and some metabolites may also be excreted in the bile/feces.

Kidney and liver considerations: If you have reduced kidney function, the medicine may build up more easily. Your clinician/pharmacist may recommend dose adjustments or close monitoring.

Typical use and timing

Naprelan is commonly used for chronic or longer-lasting pain conditions where steady relief is helpful. Because it is extended-release, it’s often taken once daily.

When to take it

• Take Naprelan as directed on your label or as advised by your healthcare professional.
• Try to take it at the same time each day to keep pain control steady.
• If it upsets your stomach, consider taking it with food (see Food interactions).

How long it takes to notice benefits

• Some people notice relief within hours, but maximum benefit for inflammation-related pain may take days.
• If you’re not getting adequate relief, don’t increase your dose without advice—discuss options with a pharmacist or doctor.

Do not crush or chew

• Extended-release tablets should usually be swallowed whole.
• Crushing/chewing may release the medication too quickly and increase side effects.

Indications (conditions Naprelan is used for)

Naprelan may be used to relieve pain and inflammation related to:

• Osteoarthritis
• Rheumatoid arthritis
• Juvenile idiopathic arthritis (where appropriate and as advised)
• Ankylosing spondylitis
• Other inflammatory pain conditions as determined by a healthcare professional

Note: The exact suitability and dosing depend on age, condition, and overall risk factors.

Dosing guidance (important)

Dosing depends on the condition being treated, your age, kidney function, and whether other medicines are used. Always follow the instructions on your packaging.

Common dosing patterns

• Extended-release naproxen is often prescribed as once daily dosing.
• Some conditions may require different starting doses or adjustments.

General principles for safe dosing

• Use the lowest effective dose for the shortest duration needed.
• Avoid taking multiple NSAIDs together (e.g., naproxen + ibuprofen + diclofenac).
• If you miss a dose, take it when you remember unless it’s close to the next dose—do not double up.

Special populations

• Older adults: Higher risk of stomach bleeding and kidney issues—may require lower doses and closer monitoring.
• Kidney impairment: May require dose reduction and monitoring.
• Liver impairment: Risk of accumulation may be increased; consult a healthcare professional.
• Children and adolescents: Suitability depends on age and specific product rules—check with a pharmacist.

Seek urgent medical advice if you accidentally take more than the prescribed dose.

Food interactions and what to eat

Food can affect how quickly naproxen is absorbed and may change stomach tolerance.

Taking with food

• Taking Naprelan with food or milk may reduce stomach irritation.
• Even when taken with food, NSAIDs can still cause ulcers or bleeding in some people.

Grapefruit and caffeine

• Grapefruit is not a common key interaction for naproxen, but individual risk factors vary.
• Caffeine and alcohol can increase stomach irritation in some people; if you notice worsening symptoms, reduce these.

Hydration matters

• Staying well hydrated supports kidney function, especially during illness (e.g., vomiting/diarrhoea) when dehydration can increase NSAID risk.

Alcohol and medicine interactions

Alcohol

Avoid or limit alcohol while taking NSAIDs such as naproxen. Alcohol can increase the risk of:

• Stomach lining damage
• Gastric bleeding
• Worsening indigestion

Other medicines that may interact

Naprelan can interact with several commonly used medicines. Tell your pharmacist or doctor about all medicines and supplements you use, including non-prescription products.

Important: This is not a complete list. Your pharmacist can provide an individual interaction check based on your medication profile.

Safety profile (side effects and when to seek help)

Like all medicines, Naprelan can cause side effects. Many people tolerate NSAIDs well, but NSAIDs carry important risks—particularly for the stomach, kidneys, and cardiovascular system.

Common side effects

• Indigestion, heartburn, stomach discomfort
• Nausea
• Headache or dizziness
• Swelling (fluid retention) in some people

Serious risks (get urgent help)

Seek urgent medical attention if you develop signs of serious complications:

• Gastrointestinal bleeding: black/tarry stools, vomiting blood, or severe abdominal pain
• Allergic reactions: swelling of face/lips, wheezing, trouble breathing, hives
• Serious skin reactions: blistering rash or peeling skin
• Signs of kidney problems: reduced urination, persistent swelling, severe fatigue
• Chest pain, sudden breathlessness, weakness on one side, or trouble speaking (possible cardiovascular/vascular events)

Who may be at higher risk

• People with a history of stomach ulcers or gastrointestinal bleeding
• Older adults
• People taking blood thinners or multiple medicines that affect bleeding
• People with kidney disease or dehydration
• People with uncontrolled high blood pressure or heart disease

Contraindications (when Naprelan may not be suitable)

Naprelan may not be appropriate if you have:

• An allergy to naproxen or other NSAIDs
• A history of NSAID-triggered asthma or severe allergic reactions
• Active gastrointestinal ulceration or bleeding
• Severe kidney impairment (depends on severity and clinical judgement)

Always consult a pharmacist/doctor if you have any of these risk factors.

Practical use tips (how to get the best benefit safely)

• Take as directed: Follow the schedule on your label.
• Swallow whole: Do not crush or chew extended-release tablets.
• Use the lowest effective dose: Reduces risk of side effects.
• Stay hydrated: Especially during hot weather or illness.
• Avoid combining NSAIDs: If you need additional pain relief, ask which option is safer for you (e.g., some people can use paracetamol, depending on their health and medicine list).
• Watch for stomach symptoms: Pain, burning, nausea, or black stools should be taken seriously.
• Review your medicines regularly: If you use Naprelan for weeks or months, check in with a pharmacist or doctor.

What to do if you feel unwell while taking Naprelan

• If you develop vomiting, diarrhoea, or cannot drink fluids adequately, your risk of kidney complications may rise. Contact a healthcare professional for advice.
• If you notice easy bruising or bleeding, contact a healthcare professional promptly.

Alternative options

If Naprelan isn’t suitable, there may be other options depending on your condition, risk factors, and previous response to treatment.

Other NSAIDs

• Different NSAIDs (e.g., ibuprofen, diclofenac) may be considered.
• However, they share many NSAID risks, so choosing a different NSAID doesn’t remove the underlying safety concerns.

Non-NSAID pain relief

• Paracetamol (acetaminophen) may be an option for some pain types and generally has a different safety profile.
• Topical therapies (e.g., anti-inflammatory gels) may help localized conditions with less systemic exposure.

Non-medicine approaches

• Physiotherapy, strengthening exercises, weight management, heat/cold therapy
• For arthritis: activity pacing and joint-protecting strategies

Your pharmacist can help compare options based on your symptoms and current medications.
