Synastone

Synastone (methadone hydrochloride) is an opioid medication used for pain relief and opioid dependence management. It works by changing how the brain responds to pain. This EU-sourced product is intended for intramuscular or subcutaneous administration. Always follow healthcare provider guidance when using.

Methadone hydrochloride is commonly used to manage moderate to severe pain when other treatments are ineffective. It is also prescribed for opioid dependence as part of maintenance therapy. The medication helps reduce withdrawal symptoms and cravings. It is typically used under medical supervision for both pain relief and addiction support.

Methadone hydrochloride may cause drowsiness, dizziness, or lightheadedness as it takes effect. Some users report feeling calm or relaxed after administration. These effects can vary depending on individual response and dosage. It is important to avoid activities requiring alertness until you know how it affects you.

Store methadone hydrochloride at room temperature away from moisture and heat. Keep it in a secure location out of reach of children and pets. Do not share this medication with others, as misuse can lead to serious health risks. Always dispose of unused medication properly through a pharmacy take-back program.

Methadone hydrochloride may interact with alcohol, causing increased drowsiness or respiratory depression. Other central nervous system depressants, such as benzodiazepines or sedatives, can enhance these effects. Certain medications, including some antidepressants and antifungals, may alter methadone levels in the body. Always inform your healthcare provider about all medications you are taking.
