Do not solve an unclear prescription instruction by guessing. If the product, label or measurement does not make sense, contact the dispensing pharmacist or prescribing clinician before using it. This guide helps organize that conversation; it is not a dosing or injection guide.
Confirm the exact product
Read the full medicine name and pharmacy information on the package. Compare them with the prescription information you were given. If something differs, ask the responsible professional to reconcile the details. A telehealth brand name does not identify every preparation its patients may receive.
If the medicine is compounded, keep that status visible. FDA does not review compounded products for safety, effectiveness and quality before marketing. A branded medicine's directions or approval should not be assumed to apply to a compounded preparation with a similar ingredient name.
Make the instructions agree
FDA has reported dosing errors with compounded injectable semaglutide involving patients and health professionals. Different concentrations and confusion among milligrams, milliliters and syringe units can create problems. This site provides no conversion chart because the exact prescription, concentration and device need professional confirmation.
Have the actual label, supplies and written directions available when asking for help. If a message from the service and the printed label appear inconsistent, show both. Ask the pharmacist or clinician to state the correct instruction clearly and check your understanding.
Recheck when something changes
A new pharmacy, concentration, device or set of directions is a reason to ask again. Familiarity with the previous shipment does not establish that the new one is used in the same way. Do not copy a measurement from a social-media post or another patient's prescription.
Ask for the storage and discard instructions specific to what you received. Keep the original packaging and instructions together so the care team can identify the product. For delivery concerns, use our package guide.
Save the help routes before you need them
- The prescribing team's clinical contact.
- The dispensing pharmacy's contact.
- The provider's process for urgent questions and delayed replies.
- In the US, Poison Help at 1-800-222-1222 for a suspected medication error or overdose.
If you think an incorrect amount has already been used, seek prompt professional guidance rather than trying to correct it with another dose. Do not wait for symptoms before asking Poison Help about a suspected poisoning. If the person has trouble breathing, collapses, has a seizure or cannot be awakened, call 911.
The practical standard is understandable instructions tied to the actual medicine. You are entitled to ask for clarification before proceeding, even if the question seems basic.
