Boost Your Quality of Life With Low Dose Naltrexone

Irsfeld Pharmacy in the News.

Low dose naltrexone (LDN) is one of the most exciting compounds Irsfeld Pharmacy PC has made since we started compounding in 1998. We have been able to help so many patients improve their symptoms and quality of life.


Naltrexone is a versatile pharmaceutical that has a wide range of applications. To see the conditions for which naltrexone can be used, please click the link below to visit the LDN Research Trust's website.

As with any medication, the key to using it wisely is to keep an open dialog with the pharmacy regarding your symptoms, condition, and experiences with LDN. We can make changes and help you to continue this treatment. As Steve Irsfeld, the pharmacist and owner of Irsfeld Pharmacy PC, always says, “Be vigilant about your health!”


For more information about low dose naltrexone, please call today. Same-day services are available, and delivery can be arranged.

Weekly Symptom Tracking

Once you start your LDN treatment, we want to track your progress. The answers to the questions help us determine dosage changes, the best delivery forms for the drug, and MOST importantly, your PROGRESS. Knowledge is the KEY. 


By completing this symptom tracker for the first 4-6 weeks of starting LDN, we can ensure the best chance for symptom reduction and side effect prevention. For us to make this PERSONALIZED for YOUR individual needs, we need your input. Experience tells us that you get out of it, what you put into it!


  • For the next 4-6 weeks, place the symptom tracker on your To-Do list for each SUNDAY and make sure you complete the survey using the link below.
  • If you experience a change while taking the medication between symptom tracking, please do not hesitate to call Irsfeld Pharmacy PC at (701) 483-4858. We don't want you to walk away from the treatment as many times a change to the dosing regimen can fix the problem allowing you to continue with the treatment. Experience tells us with dedication comes REWARD...keep that in mind on your journey, AND know that we are here to HELP.
