MIR 30mg: Uses Dosage, Side Effects, Addiction, Warnings

M.I.R 30 is morphine immediate release tablets containing 30mg of the active ingredient. Morphine belongs to the class of medications called narcotic analgesics (pain relievers). These pain relievers are also known as opioid analgesics. This medication relieves severe pain when less potent pain relievers are not effective. Opioids decrease pain by working on the brain to increase pain tolerance. Morphine immediate release works quickly. It will usually relieve pain within about 30 minutes.

Are there any other precautions or warnings for this medication?

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.

Abdominal (stomach) conditions: Morphine and other narcotic medications may make the diagnosis of abdominal conditions more difficult or it may worsen these conditions. People who experience slower-than-normal passage of material through the digestive system may experience more side effects from morphine sustained release. If you have abdominal problems, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Accidental use: Accidental ingestion or use of as little as one dose of morphine by someone for whom it has not been prescribed can lead to a fatal overdose. Children are especially at risk. Keep this medication out of sight and reach of children.

Alcohol and other medications that cause drowsiness: Do not combine this medication with alcohol or other medications (e.g., antidepressants, sleeping pills, anxiety medications) that cause drowsiness since additional drowsiness or suppressed breathing can occur and be dangerous and possibly life-threatening.

Asthma and other respiratory conditions: Morphine may cause increased breathing difficulty for people having an acute asthma attack, or those with chronic obstructive pulmonary disease (chronic bronchitis, emphysema) or other conditions that affect breathing. If you have asthma or another breathing disorder, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Breathing: Morphine can suppress breathing, particularly if taken by someone who has not taken morphine before. This is a serious, potentially life-threatening condition. If you are at risk for breathing difficulties such as asthma, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. Keep this and all medications out of reach of children.

Dependence and withdrawal: Drug addiction is usually not a problem for people who require this medication for pain relief. Physical dependence (a need to take regular doses to prevent physical symptoms) has been associated with narcotic analgesics such as morphine. Withdrawal symptoms may be experienced if the dose is significantly reduced or suddenly discontinued. These symptoms include seizures, irritability, sleep problems, agitation, tremors, diarrhea, abdominal cramps, vomiting, headache, muscle cramps, extreme anxiety, tension, restlessness, sweating, and confusion. Reducing the dose gradually under medical supervision can help prevent or decrease these withdrawal symptoms when this medication is no longer required for pain control.

Dizziness: Morphine and other narcotics may cause dramatically reduced blood pressure, resulting in dizziness and unsteadiness. To reduce the possibility of severe dizziness, rise slowly when standing from a sitting or lying position.

Drowsiness/reduced alertness: Morphine may impair the mental or physical abilities needed for certain potentially hazardous activities such as driving a car or operating machinery. Avoid these activities until you know how this medication affects you.

Head injuries: Morphine can cause increased pressure inside the head. If you have an acute head injury or other conditions that increase your intracranial pressure (pressure inside the head), discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Kidney function: Kidney disease or reduced kidney function may cause this medication to build up in the body, causing side effects. If you have reduced kidney function or kidney disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Low blood pressure: Morphine can cause low blood pressure or make low blood pressure worse. If you experience severe dizziness, especially when standing from a lying or sitting position, contact your doctor.

Liver function: If you have reduced liver function or liver disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Medical conditions: Morphine may cause increased symptoms or reduce the symptoms of worsening illness for people with Addison’s disease, reduced thyroid function, enlarged prostate, stricture of the urethra, reduced pituitary function, anemia, severe malnutrition, active ulcerative colitis, and hypothyroidism (low thyroid). If you have any of these conditions, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Seizures: Morphine may worsen preexisting seizure disorders. If tolerance to the medication develops and the dosage is increased substantially above recommended levels, seizures may occur in people without a history of seizure disorders. If you have a seizure disorder, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Serotonin syndrome: Severe reactions are possible when morphine is combined with other medications that act on serotonin, such as tricyclic antidepressants and serotonin reuptake inhibitors (medications used to treat depression). Symptoms of a reaction may include muscle rigidity and spasms, difficulty moving, or changes in mental state including delirium and agitation. Coma and death are possible.

If you are taking antidepressants, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately. Infants born to mothers who have been taking morphine for long periods of time or who are physically dependent on morphine will also be physically dependent on the medication and may experience breathing difficulties as well as withdrawal symptoms.

Breast-feeding: This medication passes into breast milk. If you are a breast-feeding mother and are taking morphine sustained release, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.

Children: Accidental ingestion of this medication by children may lead to severe and even fatal consequences. Keep this medication out of the reach of children.

Seniors: Seniors may be more sensitive to the effects of morphine and may require lower doses.
