Lantus shortage?

I’m not sure which country you’re in, but Lantus (insulin glargine) shortages have happened in various places due to manufacturing or supply issues. If you can tell me your country and whether you use Lantus vials or the SoloStar pen, I can tailor the info. In the meantime, here’s a practical plan.

What to do now
- Talk to your prescriber and pharmacist: Ask about current Lantus availability and whether a substitute is appropriate.
- Consider alternatives (discuss with your doctor):
- Basaglar (insulin glargine biosimilar) – usually a direct unit-for-unit switch.
- Toujeo (insulin glargine U-300) – different concentration and may require dose adjustment.
- Levemir (insulin detemir) or Tresiba (insulin degludec) – other long-acting options.
- Your doctor may also suggest a temporary change to a different basal insulin if needed.
- Dose and switching: Do not change your dose without medical guidance. If you switch glargine products, a 1:1 unit-per-unit substitution is often appropriate, but confirm with your clinician/pharmacist because formulations can differ and individual response varies.
- Monitor closely: Check your blood glucose more frequently during any switch or supply disruption. Have a plan for possible hypo- or hyperglycemia and know when to seek care.
- Supply management tips:
- Ask about getting a spare supply from the pharmacy or clinic.
- Check expiration dates and storage recommendations (vials vs pens).
- If you have to stretch supply, your clinician may provide a temporary plan; do not make large dose changes on your own.
- Access and support: If you have trouble affording or getting insulin, ask your clinic about patient assistance programs or manufacturer support. Some regions have drug shortage resources or official notices you can check (for the US, you can look at FDA drug shortage information and talk to your pharmacist).

If you’d like, tell me:
- Your country
- Whether you use Lantus vials or a pen
- Any alternatives your clinician has suggested or you’re considering

I can help you find region-specific guidance and draft questions you can ask your pharmacist or doctor. If you’re at imminent risk of not having insulin, seek urgent help from a local clinic, hospital, or emergency services.
