Tramedo SR


Limitations of use

TRAMEDO SR should only be used when your doctor decides that other treatment options are not able to effectively manage your pain or you cannot tolerate them.

Hazardous and harmful use

TRAMEDO SR poses risks of abuse, misuse and addiction which can lead to overdose and death. Your doctor will monitor you regularly during treatment.

Life threatening respiratory depression

TRAMEDO SR can cause life-threatening or fatal breathing problems (slow, shallow, unusual or no breathing) even when used as recommended. These problems can occur at any time during use, but the risk is higher when first starting TRAMEDO SR and after a dose increase, if you are older, or have an existing problem with your lungs. Your doctor will monitor you and change the dose as appropriate.

Use of other medicines while using TRAMEDO SR

Using TRAMEDO SR with other medicines that can make you feel drowsy such as sleeping tablets (e.g. benzodiazepines), other pain relievers, antihistamines, antidepressants, antipsychotics, gabapentinoids (e.g. gabapentin and pregabalin), cannabis and alcohol may result in severe drowsiness, decreased awareness, breathing problems, coma and death. Your doctor will minimise the dose and duration of use; and monitor you for signs and symptoms of breathing difficulties and sedation. You must not drink alcohol while using TRAMEDO SR.

1. Why am I taking Tramedo SR?

Tramedo SR contains the active ingredient tramadol hydrochloride.

Tramedo SR is used to relieve severe pain over a long period of time. It belongs to a group of medicines called opioid analgesics (pain relievers). Tramedo SR tablets are designed to release active medicine gradually over several hours.

Tramedo SR is for use in adults and children over 12 years of age and should not be used in children under 12 years of age or following the removal of tonsils and/or adenoids in people under 18.

2. What should I know before I take Tramedo SR?


Do not take Tramedo SR if:

  • you are allergic to tramadol hydrochloride, any other opioid analgesics (e.g. morphine or codeine), or any of the ingredients listed at the end of this leaflet.
    Some of the symptoms of an allergic reaction may include skin rash, itching, difficulty breathing and swelling of the face (including lips, tongue, throat etc).
    Always check the ingredients to make sure you can take this medicine.
  • you have respiratory disease or slow or shallow breathing
  • you have taken large amounts of alcohol or other substances which can affect your level of consciousness. Some examples of these substances include sleeping pills, pain relievers or other psychotropic medicines (medicines that affect mood and emotions)
  • you are taking medicine for depression containing a “monoamine oxidase inhibitor”, also known as a MAOI, or have taken one within the past two weeks. Examples of MAOI-containing medicines are Nardil®, Parnate®
  • have uncontrolled epilepsy or if your epilepsy is not well controlled by treatment
  • you are younger than 12 years old or if you are between 12 – 18 years of age and are recovering from an operation to remove your tonsils and/or adenoids

Do not use Tramedo SR after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering.


You can become addicted to Tramedo SR even if you take it exactly as prescribed.

Tramedo SR 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 Tramedo SR. Taking it may result in physical dependence. Physical dependence means that you may experience withdrawal symptoms if you stop taking Tramedo SR suddenly, so it is important to take it exactly as directed by your doctor.


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


Continue taking your medicine for as long as your doctor tells you. If you stop having this medicine suddenly, your pain may worsen and you may experience some or all of the following withdrawal symptoms:

  • nervousness, restlessness, agitation, trouble sleeping or anxiety
  • body aches, weakness or stomach cramps
  • loss of appetite, nausea, vomiting or diarrhoea
  • increased heart rate, breathing rate or pupil size
  • watery eyes, runny nose, chills or yawning
  • increased sweating.

Very rarely, some patients have experienced the following withdrawal reactions:

  • panic attacks
  • severe anxiety
  • hallucinations
  • tingling or numbness (pins and needles)
  • ringing in your ears
  • confusion, delusions or paranoia.

If you are not sure whether you should start taking Tramedo SR, talk to your doctor.

Pregnancy and breastfeeding

Check with your doctor if you are pregnant or intend to become pregnant.

Tramedo SR given to the mother during labour can cause breathing problems and signs of withdrawal in the newborn.

Talk to your doctor if you are breastfeeding or intend to breastfeed.

3. What if I am taking other medicines?

Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

Some medicines may interfere with Tramedo SR and affect how it works. These include:

  • carbamazepine (eg. Tegretol®)
  • coumarin derivatives (eg.warfarin: Some brand names are Coumadin®, or Marevan®)
  • medicine for irregular or rapid heart beat
  • some antibiotics
  • medicines for depression, sleeplessness or mental conditions such as selective serotonin reuptake inhibitors (SSRI’s), serotonin-noradrenaline reuptake inhibitors (SNRI’s), tricyclic anti-depressants, quinidine, phenothiazines or anti-psychotics

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect Tramedo SR.

4. How do I take Tramedo SR?

How much to take

The recommended dosage of TRAMEDO SR is either:

  • one or two TRAMEDO SR 100 mg tablet(s) twice a day (morning and evening); or
  • one TRAMEDO SR 150 mg or 200 mg tablet twice a day (morning and evening).

Tramedo SR tablets allow the body to absorb the active ingredient tramadol over a long period, so that dosing need be only twice a day

As all patients respond to treatment differently, your doctor may start you on a lower dose.

Do not take more than four of the 100 mg tablets per day. Do not take more than two of the 150 mg or of the 200 mg tablets per day.

Patients over 75 years may need a reduced daily dose of TRAMEDO SR compared to younger adults.

When and how to take Tramedo SR

  • TRAMEDO SR may be taken, before, with, or after food.
  • Swallow the tablets whole with a glass of water. They must NOT be chewed, crushed or dissolved. This will release all the analgesic quite quickly. Side-effects may then occur.

How long to take Tramedo SR

This differs between individuals depending on how severe your pain is, how you respond to Tramedo SR, and the cause of your pain. Ask your doctor for advice on how long you need to take Tramedo SR tablets.

If you forget to take Tramedo SR

If you forget to take a dose, you can take it as soon as you remember. The next dose should be taken after twelve hours, or as prescribed by your doctor.

Do not take a double dose to make up for the dose that you missed. This may increase the chance of you getting an unwanted side effect.

If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.

If you are not sure what to do, ask your doctor or pharmacist.

If you take too much Tramedo SR

If you or someone else receives too much (overdose), and experiences 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. You should follow the above steps even if someone other than you have accidentally used Tramedo SR that was prescribed for you.

  • Drowsiness, dizziness or unconsciousness
  • Slow or weak heartbeat
  • Nausea or vomiting
  • Convulsions or fits
