Cautions

• Before starting this medication, consider discussing the following points with your healthcare professional:
• Any other medications you're taking, as Orphenadrine can interact with other drugs, potentially increasing their effects or causing adverse reactions.
• Existing medical conditions, which could be worsened by Orphenadrine. Ensure your doctor is aware of any neurological or gastrointestinal issues.
• If you are pregnant or planning to become pregnant. Norflex may not be suitable during pregnancy, and your physician needs to be informed.

• Some people may feel light-headed, dizzy, or may faint briefly after taking Norflex.
• Norflex can affect your ability to do things that require concentration, like operating machines or driving. Be careful if you're moving around after taking it.
• Norflex injections contain sodium bisulfite which can cause severe allergic reactions, particularly in asthmatic individuals. These reactions are rare, but more common in people with asthma.

• If you're feeling confused, anxious, or shaky, and you're also taking painkillers like propoxyphene, there may be a risk of adverse effects. You may need to reduce the dose or stop taking one or both drugs.
• Be cautious with Norflex if you have a fast heartbeat, heart problems, or irregular heart rhythms.
• The safety of taking Norflex for a long time isn't known. If you're on Norflex for a while, you may need regular tests to check your blood, urine, and liver.
• During pregnancy, Norflex should only be used if absolutely necessary, as its safety for unborn babies is uncertain.

Norflex may also cause serious side effects that require medical attention, such as hallucinations and involuntary muscle movements.
