In most cases, yes. Your clinician will review your current prescription and, in most cases, keep your treatment consistent so you don't lose momentum. However, a prescription or specific dosage is not guaranteed as it is the decision of the prescribing clinician.
When completing your medical intake form, make sure to upload a copy of your current prescription (including the product name, dose, concentration, and prescriber name) to the Documents section of your portal so your clinician has everything they need. You can typically find all of this information on your prescription label.
One thing to note: without that upload, the clinician may not be able to resume your current prescription, so don't skip this step.
