Metadol 100mg is a potent opioid medication primarily used to manage severe pain in patients who do not respond to other pain relievers. It is also commonly prescribed for opioid addiction treatment under medical supervision. This guide provides essential information about Metadol 100mg, including its uses, dosage, side effects, and precautions.
What is Metadol 100mg?
Metadol contains methadone hydrochloride, a synthetic opioid that acts on the central nervous system to relieve pain and reduce withdrawal symptoms in opioid-dependent individuals. It is available in tablet form and is usually prescribed for long-term pain management or as part of a drug addiction treatment program.
Uses of Metadol 100mg
- Pain Management: Metadol 100mg is used to treat chronic pain, especially when other pain medications are ineffective.
- Opioid Dependence: It helps manage withdrawal symptoms and cravings in patients undergoing treatment for opioid addiction, such as heroin or prescription opioid dependency.

Dosage and Administration
- Dosage: The dosage of Metadol 100mg varies depending on the patient’s medical condition, response to treatment, and other medications they may be taking. It is crucial to follow the doctor’s instructions carefully.
- Administration: Metadol 100mg should be taken orally with or without food. Swallow the tablet whole without crushing or chewing it to avoid releasing the drug all at once, which can lead to an overdose.

Side Effects
Like all medications, Metadol 100mg may cause side effects. Common side effects include:
- Drowsiness: This medication may cause drowsiness, affecting the ability to drive or operate machinery.
- Nausea and Vomiting: These symptoms are common, especially at the beginning of treatment.
- Constipation: Opioids like Metadol can cause constipation. Increasing fluid intake and dietary fiber may help alleviate this condition.
More severe side effects require immediate medical attention:
- Breathing Problems: Difficulty breathing or shallow breathing can be a sign of overdose or severe reaction.
- Severe Drowsiness or Dizziness: Extreme drowsiness or dizziness may indicate an overdose.
- Allergic Reactions: Swelling, rash, or difficulty breathing could be signs of an allergic reaction.
Precautions
- Medical History: Inform your doctor about any medical history, especially related to breathing disorders, liver or kidney disease, heart problems, or mental/mood disorders.
- Drug Interactions: Metadol 100mg can interact with other medications, leading to dangerous side effects. Inform your healthcare provider about all the drugs you are currently taking, including prescription, over-the-counter, and herbal supplements.
- Pregnancy and Breastfeeding: Metadol 100mg should be used during pregnancy only if clearly needed, as it can harm the unborn baby. It passes into breast milk and may have undesirable effects on a nursing infant.
Conclusion
Metadol 100mg is an effective medication for managing chronic pain and treating opioid dependence. However, it must be used under strict medical supervision due to the potential for severe side effects and the risk of addiction. Always follow your healthcare provider’s instructions and never adjust your dose without consulting them.
