What PANADOL Night is used for

PANADOL Night is used to give temporary relief of pain when associated with sleeping difficulty.

It is useful for headache, migraine headache, backache, arthritis, rheumatic and muscle pain, neuralgia, toothache or period pain.

Paracetamol is an analgesic. It works to stop the pain messages from getting through to the brain. It also acts in the brain to reduce fever.

Diphenhydramine hydrochloride is an antihistamine that helps you sleep.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your pharmacist or doctor may have given you this for another reason.

This medicine is only available from your pharmacist.

Helpful advice on managing night pain

Managing pain at night can often be complicated by affecting your ability to get to sleep. When your sleep pattern is affected, pain at night can seem stronger than normal. For this reason we have included some helpful advice on managing pain and getting to sleep.

Pain Management

  1. Application of gentle heat to the painful area. This increases the blood flow to the affected area which works to relieve the sensation of pain and aids the healing process. Hot water bottles, hot showers and heat bags can be useful.
  2. Pain as a result of inflammation can also be treated by the application of cold to the affected area. Cold packs can often be more effective in the early stages of an injury than heat. See your doctor or pharmacist for advice on the best way to treat your pain.
  3. For some people, massage can also help to increase blood flow to an area and contribute to increasing flexibility of joints and muscles. Massage oils may help.

Sleep Routines

  1. Avoid alcohol, caffeine products and nicotine before bedtime.
  2. Avoid large meals before bedtime.
  3. Develop a regular bed time routine. This helps signal to your mind that it is time to go to sleep.
  4. Practice relaxation techniques. There are many useful books and courses available to instruct you on simple, effective techniques.
  5. Ensure your bed is comfortable. Sometimes changing a mattress or pillows can increase your comfort and ability to get to sleep, particularly if you suffer from muscle or joint pain.


Suffering from night time pain can be a lonely experience if it also stops you sleeping. Just remember, many people suffer from night time pain, you are not alone. Try some of the above techniques which could help you manage your night time pain.
