Customer Question

Hi there!
I began taking Modafonil about two weeks ago, replacing Adderall, for narcolepsy. Initially I felt like the Modafonil gave me my life back without the anxiety and other side effects I experienced while taking adderall. However, I've beem having absolutely terrible and incredibly draining anxiety and panic attacks for the past two days. I usually take 100mg of Modafonil at 8 am and another 100mg around 1pm. However, the last two days I haven't taken my first dosage until later on in the day (11am), while still taking my second at around 1/2pm. I'be also been going to sleep around 2/3am instead of 11 pm. Can that be causing the unbearable anxiety? If not, what can?

Hello and thank you for your question. Usually you only want to take Modafinil once a day and that is typically in the morning because of its longer half-life than Adderall (15-17 hours). So it is possible that splitting the dose of the Modafinil is contributing to this anxiety and panic. But yes Modafinil like any other stimulant based medication will increase anxiety and panic as that is common. You see when you are anxious and have a panic disorder, your body is already stimulated. This is why sedative medications like a benzodiazepine are so effective in lessening anxiety and panic because they slow the body down. So taking a stimulant medication like Modafinil or Adderall will only increase stimulation and exacerbate anxiety and panic.

You may want to try only taking 100mg of Modafinil in the morning to see if this helps with your narcolepsy and does not cause you the anxiety and panic that you are experiencing. If your narcolepsy is still not resolved, but you are not experiencing panic or anxiety than increasing to 200mg once in the morning would be appropriate. But splitting the dose to twice a day is most likely contributing to your anxiety and definitely the insomnia as this medication is not meant to be taken in the afternoon.

I hope this answers your questions and gives you some guidance on this issue. Please let me know if you have any questions or concerns as I am happy to assist and support you regarding this issue.
