"I forgot to take my dose of duloxetine before sleeping, can I take it in the morning instead? Knowing that my next dose will be around 10pm?"

Yes, you can take your missed dose of duloxetine in the morning and then take your next dose at 10 PM. It is generally recommended to follow the "12-hour rule" for medications taken every 24 hours. If the next dose is due in less than 12 hours, it is best to skip the missed dose and take the next dose as scheduled. If the next dose is due in more than 12 hours, you can take the missed dose immediately and then take the next dose at the regular time. Ultimately, the decision is up to you based on how you are feeling and any concerns you may have about taking the medication.
