<s>[INST] I have been prescribed Levsin extended release for esophageal spasms. I have achalasia & have had a Heller myotomy with Dor fundoplication. My Prescription Drug plan does not have Levsin or it s generic in their formulary * it s expensive - about $3/day for 0.375mg tablet twice daily. Is there another medication that could substitute for Levsin? [/INST] Hello, Levscin is anticholinergic antispasmodic  drug. There are many medications that you can use like Buscopan but is better to talk with your doctor. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Blerina Pasho, General & Family Physician </s>
