Back to MK-677 overview

  • Active malignancy
  • Congestive heart failure (fluid retention risk)
  • Pregnancy and breastfeeding

Drug Interactions (5 interactions)

Important: This table summarizes known and theoretical interactions. Always consult a healthcare provider before combining MK-677 with any medication.
Drug Classification Mechanism
Insulin / oral hypoglycemics Documented MK-677 increases fasting glucose and insulin resistance — dose adjustments needed
Somatostatin analogs (octreotide) Documented Somatostatin suppresses GH release, opposing MK-677 effect — separate by 4+ hours
Glucocorticoids Theoretical Both may impair glucose metabolism; additive hyperglycemia risk
GH therapy (somatropin) Theoretical Additive GH elevation — avoid combination to prevent supraphysiologic levels
GHRPs (GHRP-6, GHRP-2) Theoretical Additive GH secretion through overlapping pathways
