Hey and thank you so much for the query. Bother not about the cost. At healthcaremagic, even if you cannot pay we shall always attend to you. None should be excluded from our services because of financial difficulties. There is no connection between prescribing permethrin and ranitidine. My best guess is that you may have had another disease like gastritis that prompted the prescription of this medication. Ask your doctor why this drug was prescribed and whether you need to refill it or not. I wonder if it would be the case if you no longer have any symptoms. I hope your scabies is completely taken care of already. Remember to also wash and disinfect all your linen to avoid re-infestation. Also, treat every sick family member to guarantee complete eradication from the household. I hope this helps and addresses your query fully. Thank you fo rusing our services. I wish you well and feel free to ask many more questions if need be. Dr. Ditah, MD
