Contents of the Package Leaflet:
Morphine is an opioid analgesic that acts directly on the pain center. In humans, its action is translated into analgesia and often into narcosis.
This medicine is indicated in:
Do not useMorphine SERRA
Tolerance, dependence, and addiction
This medicine contains morphine, which is an opioid. Repeated use of opioids can lead to reduced efficacy of the medicine (getting used to it, known as tolerance). Repeated use of Morphine SERRA can also lead to dependence, abuse, and addiction, which could result in a potentially fatal overdose. The risk of these adverse effects may be greater with a higher dose and longer use.
Dependence or addiction can lead to a feeling of lack of control over the amount of medicine you need to use or how often you need to use it.
The risk of dependence or addiction varies from person to person. You may have a greater risk of dependence or addiction to Morphine SERRA if:
If you notice any of the following symptoms while taking Morphine SERRA, it could be a sign of dependence or addiction:
If you notice any of the following symptoms while taking Morphine SERRA, it could be a sign of dependence or addiction:
If you notice any of these symptoms, consult your doctor to determine the best course of treatment for you, including when it is appropriate to stop the medicine and how to do so safely (see section 3 "If you stop treatment with Morphine SERRA").
Warnings and Precautions
Consult your doctor, pharmacist, or nurse before starting to use Morphine SERRA.
Consult your doctor or pharmacist if you experience any of the following symptoms while using Morphine SERRA:
Repeated administration of Morphine SERRA produces tolerance, characterized by the need to progressively increase the dose, with physical and psychological dependence. There is cross-tolerance and cross-dependence between opioids that act on the same pain receptors. Dependence usually occurs after 1-2 weeks of administering therapeutic doses, although some dependence may appear after 2 or 3 days.
Sudden interruption of treatment in patients with physical dependence can precipitate a withdrawal syndrome. Withdrawal symptoms may also appear after the administration of a medicine with an effect opposite to that of opioids (Naloxone or Naltrexone) or a medicine with a similar/contrary effect (pentazocine) to patients dependent on opioids. Physiological dependence can occur, which becomes evident due to the withdrawal syndrome that occurs if treatment is abruptly discontinued. Without treatment, most of these symptoms disappear within 5 to 14 days, although a secondary withdrawal syndrome with irritability, insomnia, and muscle pain can persist for several months.
Use in elderly patients: Special care should be taken in the elderly due to their increased sensitivity. The elderly are more susceptible to the effects of morphine.
In patients with a history of alcohol or drug dependence: Special care should be taken due to the patient's predisposition to drug addiction.
It should be administered with caution in very young patients as they may be more sensitive to the effects of morphine.
Special precautions should be taken with Morphine SERRA:
Acute generalized exanthematous pustulosis (AGEP) has been reported in association with Morphine SERRA treatment. Symptoms usually occur within the first 10 days of treatment. Inform your doctor if you have ever suffered from a severe skin rash or skin peeling, blisters, and/or sores in the mouth after taking Morphine SERRA or other opioids. Stop using Morphine SERRA and seek immediate medical attention if you notice any of the following symptoms: blisters, widespread skin peeling, or pus-filled spots (pustules) along with fever.
Sleep-related respiratory disorders
Morphine SERRA can cause sleep-related respiratory disorders, such as sleep apnea (pauses in breathing during sleep) and sleep-related hypoxemia (low oxygen level in the blood). Symptoms may include pauses in breathing during sleep, nighttime awakenings due to dyspnea, difficulties maintaining sleep, or excessive daytime sleepiness. If you or someone else observes these symptoms, contact your doctor. Your doctor may consider reducing the dose.
Contact your doctor if you experience severe upper abdominal pain that may radiate to the back, nausea, vomiting, or fever, as it could be symptoms associated with pancreatitis and bile duct inflammation.
Use in athletes
This medicine contains morphine hydrochloride, which may produce a positive result in doping tests.
Morphine SERRA may alter the results of the following laboratory tests:
Using Morphine SERRA with other medicines
Tell your doctor or pharmacist that you are using, have recently used, or might use any other medicines, even those obtained without a prescription, homeopathic medicines, herbal remedies, and other health-related products, as it may be necessary to interrupt treatment or adjust the dose of one of them.
There are some medicines with which the use of morphine is not recommended unless strictly necessary:
A large number of drugs can interact with morphine hydrochloride injection, which can significantly alter their effects. These drugs include:
Some medicines, when taken at the same time as Morphine SERRA, can affect the mechanism of action of morphine, increasing its effects:
There is a group of medicines that decrease the effect of morphine, including:
This is especially important if you are taking any of the following medicines or medicines for:
Using Morphine SERRA with food, drinks, and alcohol
Concomitant administration of Morphine SERRA with alcohol produces mutual potentiation of toxicity, with increased central depression.
Pregnancy, Breastfeeding, and Fertility
If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine.
This drug crosses the placenta. Regular use during pregnancy can produce physical dependence in the fetus, resulting in withdrawal symptoms in the newborn. The use of this medicine is only accepted in the absence of safer alternatives.
Morphine passes into breast milk.
Although no problems have been described in humans, the possible adverse effects on the infant are unknown, so your doctor must assess the benefit-risk balance.
If Morphine SERRA is used for a prolonged period during pregnancy, there is a risk that the newborn may present with withdrawal symptoms, which must be treated by a doctor.
Driving and Using Machines
Ask your doctor if you can drive or use machines during treatment with Morphine SERRA. It is essential that before driving or using machines, you observe how this medicine affects you. Do not drive or use machines if you feel drowsy, dizzy, have blurred vision, or see double, or have difficulty concentrating. Be especially careful at the start of treatment, after a dose increase, after a change in formulation, and/or when administering it concomitantly with other medicines.

This information is intended only for healthcare professionals:
The rapid intravenous injection of opioid analgesics can cause anaphylactoid reactions, so it will only be performed by doctors with experience in this administration and they must have available equipment for artificial ventilation and opioid antagonist medications.
When this medication is administered via the epidural and intrathecal routes, patients must be adequately monitored for at least 24 hours, as respiratory depression may occur.
When morphine is administered parenterally, the patient must be lying down and should remain recumbent to minimize adverse reactions such as hypotension, dizziness, drowsiness, nausea, and vomiting.
For epidural or intrathecal administration, it is preferable to inject in the lumbar region, due to the increased risk of respiratory depression when administered in the thoracic region.
If morphine is administered epidurally or intrathecally during labor, it can easily enter the fetal circulation, potentially causing respiratory depression in the newborn, especially if premature.
Before epidural administration, the correct placement of the needle or catheter in the epidural space should be checked. An aspiration can be performed to check for the presence of cerebrospinal fluid or blood, which would indicate subdural or intravascular placement, respectively.
In patients with shock, the alteration of perfusion may prevent complete absorption after intramuscular or subcutaneous administration. Repeated administration may lead to overdose due to the unexpected absorption of an excessive amount when circulation is recovered.
Physical-chemical incompatibility (precipitate formation) has been demonstrated between morphine sulfate solutions and 5-fluorouracil solutions.
The average price of MORPHINE SERRA 10 mg/mL INJECTABLE SOLUTION in October, 2025 is around 0.73 EUR. Prices may vary depending on the region, pharmacy, and whether a prescription is required. Always check with a local pharmacy or online source for the most accurate information.
