Morphine

Morphine is a strong opioid painkiller used for severe pain, including pain after surgery or injury, cancer pain and palliative care. This guide covers morphine uses, how it works, dosage, side effects, precautions, drug interactions, use in pregnancy and breastfeeding and its approximate price in India.

At a Glance

What Is Morphine?

Morphine is a strong opioid analgesic. The NHS says it is used for severe pain, including pain after surgery or injury, cancer pain and end-of-life (palliative) care. US labelling says opioids should be used only for pain severe enough to need one when other treatments are not adequate. Morphine can cause addiction and life-threatening slowed breathing, so it must be used only as prescribed.

How Morphine Works

Morphine is an opioid agonist that acts mainly on mu-opioid receptors in the brain and spinal cord, changing how the body perceives pain. It also causes sleepiness and can produce a feeling of euphoria, which is one reason it can be misused and lead to addiction.

Uses of Morphine

Morphine is commonly prescribed for:

• Pain after surgery, including after major or cancer-related procedures
• Cancer pain, especially in advanced disease
• Severe pain from injury or trauma

The US label for morphine tablets lists acute pain (in adult and pediatric patients weighing at least 50 kg) and chronic pain (in adults), in each case severe enough to need an opioid. Morphine is not for mild pain or casual use, and treatment should continue only if the pain stays severe and other options remain inadequate.

Dosage and How to Take Morphine

Morphine dosing is individualized by a qualified healthcare professional. It depends on why morphine is prescribed, the form (immediate-release tablet, prolonged-release tablet, oral liquid or injection), the patient’s age, weight, kidney and liver function, other medicines and any previous opioid use. Dose, interval and instructions differ between forms and between patients, and taking more than prescribed can be fatal.

US label example, for information only (immediate-release tablets, adults who have not taken opioids before): 15 mg to 30 mg every 4 hours as needed for pain, using the lowest dose that gives adequate relief, adjusted by the doctor according to response. This is not a personal dosing instruction, it does not apply to prolonged-release tablets, liquids or injections, and Indian prescribing may differ.

Other forms: prolonged-release tablets, oral liquids and injections have their own labelled dosing and schedules. Injection is given by trained healthcare professionals. Do not use the dose or interval for one form for another.

Children: use in children needs specialist or qualified medical supervision. Different sources address different products:

• The US morphine tablet label is weight-based: it lists acute pain in pediatric patients weighing at least 50 kg and says the tablets are not recommended under 50 kg.
• The NHS says most adults and children aged 6 months and over can take morphine, which describes general prescribing in the UK and is not product-specific.

These statements address different products and settings. They are not a dosing rule for any child, and no pediatric dose is given here.

Older adults and people with kidney or liver problems: the US injection label advises starting with a lower dose and increasing slowly with close monitoring.

Taking it: swallow tablets whole with water, and use the measuring device supplied with liquid forms (NHS). Keep the medicine securely away from children, because accidental ingestion of even one dose can be fatal, especially in children.

Stopping: do not stop suddenly after regular use, because withdrawal symptoms can occur. Your doctor will reduce the dose gradually.

Take this medicine only as advised by your doctor or healthcare professional. Do not start, stop, or change the dose on your own.

Side Effects of Morphine

Common side effects (NHS): constipation, nausea, vomiting, sleepiness, dizziness, confusion, headache, and itchy skin or rash.

Serious side effects (US labelling and NHS)

• Slowed or difficult breathing (respiratory depression), which can be fatal, especially when starting or after a dose increase
• Addiction, abuse and misuse, which can occur even at recommended doses and can lead to overdose and death
• Dependence, tolerance and withdrawal if stopped suddenly after regular use
• Severe low blood pressure and fainting
• Serotonin syndrome, mainly with certain other medicines
• Seizures, which may become more frequent in people with a seizure disorder
• Adrenal insufficiency, reported more often after more than a month of use
• Severe allergic reactions (anaphylaxis), including swelling of the throat or tongue and a raised itchy rash
• An unusual heartbeat and vision changes (NHS)

Morphine Overdose Symptoms and Emergency Warnings

Taking an extra dose of morphine can be dangerous. Opioid overdose can cause serious, life-threatening slowed or difficult breathing. Combining morphine with alcohol, benzodiazepines or other sedating medicines can cause profound sedation, slowed breathing, low blood pressure, coma and death.

If you or someone else has taken more than prescribed, or you suspect an overdose, contact emergency services or get urgent medical help immediately. Do not drive yourself. Ask someone to take you or call an ambulance, and take the medicine pack with you.

Seek emergency care immediately for slow or difficult breathing, swelling of the face, lips or throat, fainting, or a seizure. Contact your doctor promptly for severe drowsiness, confusion, a fast or unusual heartbeat, or severe constipation or abdominal pain.

Morphine Precautions and Warnings

Formal contraindications. Contraindications are product-specific. The US morphine injection label lists

• Significant respiratory depression
• Acute or severe bronchial asthma in an unmonitored setting or without resuscitation equipment
• Known or suspected gastrointestinal obstruction, including paralytic ileus
• Use of an MAOI currently or within the last 14 days
• Hypersensitivity to morphine

These come from the injection label. Tablets and other forms have their own labelling, and your doctor and pharmacist will check the product you are prescribed.

Warnings and precautions, which are not formal contraindications. The NHS says morphine may not be suitable, and your doctor should know, if you have had an allergic reaction to morphine or another opioid, a liver or heart condition, a lung condition such as asthma, a past addiction to alcohol, prescription medicines or illegal drugs, a bowel blockage, or a head injury. The US injection label also advises caution in seizure disorders and in low blood pressure or circulatory shock.

Driving and machinery: if you feel dizzy, sleepy or confused, do not drive, ride a bike or use machinery until the symptoms pass.

Monitoring: doctors assess the risk of misuse before prescribing and reassess regularly. Breathing is watched closely when starting treatment or increasing the dose.

Morphine should only be used as prescribed, because of its addictive properties and the risk of respiratory depression.

Morphine Drug Interactions

This is not a complete list. Tell your doctor and pharmacist about all prescription and OTC medicines, supplements and herbal products you use.

Morphine in Pregnancy and Breastfeeding

• Pregnancy: prolonged use of opioids during pregnancy can cause neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized and treated (US label). The US injection label says human data do not show an increased risk of congenital malformations, though the studies have limitations, and animal studies showed fetal effects at high doses. It is not recommended during or just before labor. The NHS says morphine is sometimes used in pregnancy if needed, after the doctor discusses risks and benefits. Tell your doctor if you are pregnant or planning a pregnancy.
• Breastfeeding: morphine is present in breast milk. The US label advises monitoring breastfed infants for excess sleepiness and slowed breathing, and withdrawal can occur in the infant when the mother stops. The NHS says morphine is not usually used while breastfeeding because of the chance of side effects in the baby, but a doctor may recommend it if the benefits outweigh the risks, or suggest a different painkiller. This is not an absolute ban, and the decision depends on your situation, so ask your doctor.

Is Morphine a Controlled Medicine in India?

Morphine is a narcotic drug regulated in India under the Narcotic Drugs and Psychotropic Substances (NDPS) framework. A Supreme Court order of 1 April 2016 records that morphine was among the opioids covered by amendments in 2014 and 2015 that created simplified rules for medically used “essential narcotic drugs”. Prescribing and dispensing requirements are specific, so follow your doctor’s and pharmacist’s instructions. Do not buy or share morphine without a valid prescription.

Morphine Brands, Strengths and Price in India

A common Indian brand is Duramor (Biological E). Retailer listings show 10 mg and 30 mg tablets. One listing shows a strip of 10 tablets and describes the product as habit-forming and requiring a prescription. These details come from retailer pages and were not confirmed against an official label. The listings did not state whether the tablets are immediate-release or prolonged-release. One page mentions relief “for up to 12 hours”, but that does not establish the formulation. Ask your doctor or pharmacist which type you have.

Price: a reliable current price could not be confirmed, because the listings checked showed the product as “not available” or “out of stock”, so no price is published. Availability and price vary by pharmacy and location.
