I suppose you can just...ask.
Is there a reason why you want to increase your medication? You may want to list the reasons so that you can give these to your doctor. Remember that more is not always better with certain medications. Your doctor will want to give you the most effective dose for you.
Let us know more about what is going on. The more details you provide about your situation the better we can provide resources and information.
Thank you for your question!
I am just starting medication because I put off seeking help because I was afraid the "white coats" wouldn't agree. I went to a psychiatrist for insurance purposes and he has been great at asking for my input on the medication. He started me with 10mg adderall xr with instructions to build up to 30mg a day. Then we tried 20mg twice a day; because I have college classes at night. Now we are trying 10mg standard adderall and 30mg xr together in the morning. I agreed with the other poster that explaining what you want to achieve by increasing the dose should be helpful
