Just a few questions from our Pharmacist before you checkout to make sure this medicine is safe for you.
What is Almus Period Pain Reliever?
Almus Period Pain Reliever is a fast-acting tablet containing the active ingredient naproxen. It’s used to provide effective relief from period discomfort and pain in women aged 15-50.
Naproxen is a part of a group of medicines known as Non-Steroidal Anti-Inflammatory Drugs, or NSAIDs, which means that it relieves pain while also helping to reduce swelling. This makes Almus Period Pain Reliever perfect to relieve these period symptoms.
Almus Period Pain Reliever is available over the counter, meaning you don’t need a prescription. Simply complete a short form so we can make sure this medicine is safe for you.
How does Almus Period Pain Reliever work?
Almus Period Pain Reliever works by reducing the production of prostaglandins, which in excess can cause prolonged inflammation, resulting in painful periods.
The tablet is gastro-resistant, meaning it has a coating that helps to protect it from stomach acid. This allows the tablet to release naproxen further down the gut and provide effective relief.
How long does it last?
Almus Period Pain Reliever provides relief for around 6-8 hours.
How to take Almus Period Pain Reliever
You take Almus Period Pain Reliever by swallowing the tablet whole with water, preferably with or after food.
For women aged 15-50 years old:
- On the first day take two tablets, then if needed, one tablet after 6-8 hours.
- If needed, on the second and third day take one tablet every 6-8 hours.
- You should not crush or chew the tablet, and you should only take the lowest effective dose for the shortest amount of time to reduce any side effects.
You should not exceed the maximum dose of three tablets a day for longer than three days. If you feel like you need to use it for longer, contact a doctor or pharmacist for other options and advice.
Possible side effects
Like all medicines, the active ingredient naproxen can cause side effects, although not everyone will experience them. Common side effects may include:
- constipation or diarrhoea
- dizziness
- feeling tired
- bloating and stomach pain
- headaches

- a rash
- ringing in your ears (tinnitus)
You should speak to a pharmacist or doctor if you have any side effects that don’t go away or affect your day-to-day life.
