What is Dolased

The name of your medicine is Dolased.

It contains the active ingredients paracetamol, doxylamine succinate and codeine phosphate hemihydrate.

Paracetamol, an analgesic with antipyretic action also reduces fever.

Doxylamine succinate is an antihistamine with pronounced sedative effects.

Codeine phosphate hemihydrate is an opioid analgesic, and in combination with paracetamol and doxylamine produces greater analgesia than any of these drugs alone and avoids the side effects associated with large doses of these components.

Dolased tablets contain no aspirin.

What Dolased is used for

Dolased provides temporary relief of acute moderate pain and fever.

Your doctor or pharmacist may recommend Dolased for another reason. If you want more information ask your doctor or pharmacist.

If you take too much (overdose)

If you or someone else receive too much (overdose), and experience one or more of the symptoms below call triple zero (000) for an ambulance. Keep the person awake by talking to them or gently shaking them every now and then.

Depending on your body’s individual ability to break down codeine, you may experience signs of overdose even when you take Dolased as recommended by your doctor. If overdose symptoms occur, seek immediate medical advice.

Things to be careful of:

You can become addicted to Dolased even if you take it exactly as prescribed. Dolased may become habit forming causing mental and physical dependence. If abused it may become less able to reduce pain.

As with all other opioid containing products, your body may become used to you taking Dolased. Taking it may result in physical dependence. Physical dependence means that you may experience withdrawal symptoms if you stop taking Dolased suddenly, so it is important to take it exactly as directed by your doctor.

Tolerance to Dolased may develop, which means that the effect of the medicine may decrease. If this happens, more may be needed to maintain the same effect.

While you are taking Dolased

Things you must do

If you are about to start taking any new medicine tell your doctor and pharmacist that you are taking Dolased.

Tell all of the doctors, dentists, and pharmacists that are treating you that you are taking Dolased.

If you plan to have surgery that needs a general anaesthetic, tell you doctor or dentist that you are taking Dolased.

Things you must not do

Do not give Dolased to anyone else, even if they have the same condition as you.

Do not use Dolased to treat any other complaints unless your doctor or pharmacist tells you to.

Do not drink alcohol.

Things to be careful of

Be careful driving or operating machinery until you know how Dolased affects you.

Dolased may cause drowsiness or light-headedness in some people and affect mental alertness. Make sure you know how you react to Dolased before you drive a car, operate machinery, or do anything else that could be dangerous if you are dizzy. If you drink alcohol, dizziness or drowsiness could be worse.

Codeine may be habit forming if taken frequently and over a long period of time. Please ask your doctor or pharmacist if you are concerned about this.

About 8% of people are poor metabolisers of codeine and Dolased may not work as well if you are one of those people.’

  • skin rashes,
