Therapeutic range?

If you’re in the therapeutic range of medication, does that mean that the medication should be working?

The answer is not always. Being in the therapeutic range means that the blood concentration of a medication is within the range that is generally considered effective and safe based on population studies. However, just being in this range doesn't guarantee the medication is working optimally for you. It means the dose is in the right ballpark, but your response still needs to be assessed clinically.
Yes -( but - hopefully it is the correct medication for your situation )
The therapeutic range of a drug is the dosage range or blood plasma or serum concentration usually expected to achieve the desired therapeutic effect. This does not mean that patients may not achieve benefit at concentrations below the minimum threshold, or may not experience adverse effects if kept within the range.

Whether the medication is working depends on how long you have been taking the medication and what the expected time is for the medication to be effectively working.
