Yes, you can, especially if the medication is used as directed by your doctor. There are no contraindications to the simultaneous use of the drugs mentioned in the question.

As these medications, Nedal and Doxepin, are prescription-only, please follow your doctor's instructions. I also encourage you to inform your attending physician about all the medications and dietary supplements you use, which will allow you to choose safe and effective pharmacotherapy.

I have attached links to check the availability of medicines and make a reservation at the pharmacy of your choice:
