Yikes! Check with your provider to see what they recommend you do. They may have a supply they can give you to hold you until the shortage is resolved at your pharmacy. Your provider may also be able to recommend an alternate med. A third option is to ask the pharmacy to contact other pharmacies in an effort to find a supply of the Lantus SoloStar pens. I used to use Lantus and I recall using something called Basaglar as an alternative. I now have an insulin pump (as @celia16 mentioned above). The backup plan for that is a Tresiba pen for long acting basal and a Humalog pen for quick acting bolus and correction. Today is Friday. Can you access your provider to get this resolved before the weekend?
