Check with your doctor if you are concerned about any of the above. This medicine is only suitable for long lasting pain and is not intended for pain which only lasts for short periods.

Using this medicine regularly, particularly for a long time, can lead to addiction. Your doctor, pharmacist or nurse should have explained how long you will be using it for and when it is appropriate to stop, how to do this safely.

Rarely, increasing the dose of this medicine can make you more sensitive to pain. If this happens, you need to speak to your doctor, pharmacist or nurse about your treatment.

Addiction can cause withdrawal symptoms when you stop using this medicine. Withdrawal symptoms can include restlessness, difficulty sleeping, irritability, agitation, anxiety, feeling your heartbeat (palpitations), increased blood pressure, feeling or being sick, diarrhoea, loss of appetite, shaking, shivering or sweating. Your doctor, pharmacist or nurse will discuss with you how to gradually reduce your dose before stopping the medicine. It is important that you do not stop using the medicine suddenly as you will be more likely to experience withdrawal symptoms.

Opioids should only be used by those they are prescribed for. Do not give your medicine to anyone else. Using higher doses, or more frequent doses of opioid, may increase the risk of addiction. Overuse and misuse can lead to overdose and/or death.

Tolerance, dependence, and addiction

This medicine contains morphine which is an opioid medicine. Repeated use of opioids can result in the drug being less effective (you become accustomed to it, known as tolerance). Repeated use of Morphine Sulfate Injection can also lead to dependence, abuse, and addiction, which may result in life-threatening overdose. The risk of these side effects can increase with a higher dose and longer duration of use.

Dependence or addiction can make you feel that you are no longer in control of how much medicine you need to take or how often you need to take it.

The risk of becoming dependent or addicted varies from person to person. You may have a greater risk of becoming dependent on or addicted to Morphine Sulfate Injection if:

• You or anyone in your family have ever abused or been dependent on alcohol, prescription medicines or illegal drugs (“addiction”).
• You are a smoker.
• You have ever had problems with your mood (depression, anxiety, or a personality disorder) or have been treated by a psychiatrist for other mental illnesses.

If you notice any of the following signs whilst taking Morphine Sulfate Injection, it could be a sign that you have become dependent or addicted:

• You need to take the medicine for longer than advised by your doctor
• You need to take more than the recommended dose
• You are using the medicine for reasons other than prescribed, for instance, ‘to stay calm’ or ‘help you sleep’
• You have made repeated, unsuccessful attempts to quit or control the use of the medicine
• When you stop taking the medicine you feel unwell, and you feel better once taking the medicine again (‘withdrawal effects’)

If you notice any of these signs, speak to your doctor to discuss the best treatment pathway for you, including when it is appropriate to stop and how to stop safely (See section 3, If you stop taking Morphine Sulfate Injection).

Take special care with Morphine Sulfate Injection:

Acute generalized exanthematous pustulosis (AGEP) has been reported in association with Morphine Sulfate Injection treatment. Symptoms usually occur within the first 10 days of treatment. Tell your doctor if you have ever developed a severe skin rash or skin peeling, blistering and/or mouth sores after taking Morphine Sulfate Injection or other opioids. Stop using Morphine Sulfate Injection and seek medical attention immediately, if you notice any of the following symptoms: blistering, widespread scaly skin or pus-filled spots together with fever.

Sleep-related breathing disorders

Morphine Sulfate Injection can cause sleep-related breathing disorders such as sleep apnoea (breathing pauses during sleep) and sleep related hypoxemia (low oxygen level in the blood). The symptoms can include breathing pauses during sleep, night awakening due to shortness of breath, difficulties to maintain sleep or excessive drowsiness during the day. If you or another person observe these symptoms, contact your doctor. A dose reduction may be considered by your doctor.

Contact your doctor if you experience severe upper abdominal pain possibly radiating to the back, nausea, vomiting or fever as this could be symptoms associated with inflammation of the pancreas (pancreatitis) and the biliary tract system.

Tell your doctor or pharmacist if you are using, have recently used or might use any other medicines.

This is especially important if you are taking any of the medicines mentioned below or medicines for:

• Rifampicin to treat e.g. tuberculosis
• Concomitant use of Morphine Sulfate Injection and sedative medicines such as benzodiazepines or related drugs increases the risk of drowsiness, difficulties in breathing (respiratory depression), coma and may be life-threatening. Because of this, concomitant use should only be considered when other treatment options are not possible.

However, if your doctor does prescribe Morphine Sulfate Injection together with sedative medicines the dose and duration of concomitant treatment should be limited by your doctor.

Please tell your doctor about all sedative medicines you are taking, and follow your doctor’s dose recommendation closely. It could be helpful to inform friends or relatives to be aware of the signs and symptoms stated above. Contact your doctor when experiencing such symptoms.

• Are taking gabapentin or pregabalin to treat epilepsy and pain due to nerve problems (neuropathic pain)
• Are taking medicines to treat depression
• Are taking medicines for sickness (phenothiazines), for drying secretions (anticholinergics e.g. hyoscine) or other pain killers
• Have taken one of a group of drugs called monoamine oxidase inhibitors (used to treat depression) within the last two weeks
• Are taking anti-psychotics, cimetidine, domperidone or metoclopramide
• Are taking esmolol, mexiletine or ritonavir
• Some medicines used to treat blood clots (e.g. clopidogrel, prasugrel, ticagrelor) may have delayed and decreased effect when taken together with morphine.

Do not use Morphine Sulfate Injection if you are pregnant or think you might be pregnant unless you have discussed this with your doctor, pharmacist or nurse and the benefits of treatment are considered to outweigh the potential harm to the baby.

If you use Morphine Sulfate Injection during pregnancy, your baby may become dependent and experience withdrawal symptoms after the birth which may need to be treated.

Do not use Morphine Sulfate Injection while you are breastfeeding as morphine sulfate passes into breast milk and will affect your baby.
