The table below lists the known side effects, but some of these effects may actually be the desired therapeutic effects in certain medical contexts.
It’s important to understand that people can have varying responses to medications, and what one person experiences may differ from another. If a specific side effect is not listed, it’s less likely to be directly caused by the medication, but this does not rule out the possibility entirely.
In cases where you suspect a medication may be causing an unwanted effect, adjusting the medication, trying an alternative treatment, or discontinuing the medication can help clarify whether the side effect is medication-related or has another underlying cause.
