Doses and side effects in the ALA trials

  • SYDNEY 2 (181 people with diabetic neuropathy, 5 weeks): 600, 1,200 and 1,800 mg once daily were tested; nausea, vomiting and vertigo rose with dose.[1]
  • The SYDNEY 2 authors judged 600 mg once daily the best balance of benefit and risk.[1]
  • NATHAN 1 (4 years, 600 mg once daily): serious adverse events in 38.1% on ALA versus 28.0% on placebo.[2]
  • In a 6-month trial of 38 adults with type 2 diabetes randomized to placebo or 300 to 1,200 mg a day, fasting glucose and A1C trended down with dose.[3]
  • Mounjaro's label: with a sulfonylurea or insulin, the risk of low blood sugar may rise, and a lower dose of those medicines may reduce it.[4]

Act on these

  • Low blood sugar signs listed for Mounjaro include dizziness, sweating, confusion or drowsiness, headache, blurred vision, shakiness and a fast heartbeat.[4]
  • Diarrhea, nausea and vomiting can cause a loss of fluids (dehydration) that may lead to kidney problems: tell your provider if they keep going.[4]

To ask at the next visit

  1. Should my sulfonylurea or insulin be adjusted while I take ALA?
  2. Which fasting reading should make me call you?
  3. Is a TSH check worth doing before I start, or only if I feel unwell?
  4. Is my ALA dose close to what was studied for the reason I take it?
  5. If nausea builds after an injection, should I pause ALA first?
