About Naprosyn® Pain Relief

Naprosyn® Pain Relief provides long-lasting, anti-inflammatory relief for back, muscle and joint pain. From just one dose, you can benefit from up to 12 hours of uninterrupted pain relief helping you to get on with your day. Naprosyn® Pain Relief contains the non-steroidal anti-inflammatory drug, naproxen. 

Pain can either be acute or chronic, depending on how long-lasting it is. Chronic pain typically stays long after the body has healed and may be constant or come and go. Acute pain is generally short-term and stops after what caused it has healed.

You can experience pain in different parts of your body, from your muscles to your back, and in joints such as your shoulder, wrist, or knee. Musculoskeletal (MSK) pain can be caused by injury, strain, or conditions like arthritis and can affect your mobility, comfort, and day-to-day life.

Types of pain can include:

Muscle Pain

Injuries can cause pain in your muscles alongside swelling, bruising or stiffness in the affected area. 

Joint Pain

Joint pain can affect multiple parts of the body, from your ankle to your neck. It is often caused by injury or a condition such as arthritis. 

Sprains and Strains

Sprains and strains can cause pain, tenderness and weakness, affecting muscles and ligaments.  

Naprosyn® Pain Relief offers powerful pain relief without a prescription from pharmacies.

Musculoskeletal pain accounts for up to 30% of GP consultations in the UK.

Game-changing medicine for acute back, muscle and joint pain.

Until now, naproxen has only been available on prescription for back, muscle and joint pain. Available in pharmacies nationwide, the launch of Naprosyn® Pain Relief 250 mg gastro-resistant tablets marks the first single-ingredient oral pain relief medicine available in high street pharmacies for over a decade.

In October 2025, we showcased Naprosyn® Pain Relief for the first time at The Pharmacy Show. It was an incredible opportunity to connect with passionate pharmacy professionals, share the Maxwellia story, and receive such positive feedback on our latest OTC innovation.
