I tried to refill my Nature-Throid this morning. They tell me it's been on back-order for months, and my pharmacy is substituting WP Thyroid. Can't get Nature-Throid any more, but WP Thyroid is made by the same company. But my pharmacy says that they are about to run out of WP. OK, no problem. So I went to refill my Buspirone, nope - no 10 mgs buspirone available by ANY generic manufacturers!! Mylan no longer available. All generic 10mgs. on back order also, not available at present time. Anyone else aware of problems filling chronic prescriptions? I've been taking one of them for 20 yrs with no problems and the other one over 3 years. I have filled both scripts at both Walmart and CVS in the past with no problems. What's up???
