Mescaline and Propranolol Clinician Review
Mescaline can increase BP and HR via sympathomimetic tone. Propranolol may blunt tachycardia but not necessarily prevent hypertensive response. Propranolol label includes unopposed alpha/catecholamine warnings.
Evidence: FDA label (Inderal) + mechanistic
GLP-1/GIP Agonist

Mescaline and Zepbound (tirzepatide) Clinician Review
Mescaline commonly causes nausea. Zepbound's delayed gastric emptying and high nausea/vomiting/diarrhea rates create additive GI burden and timing uncertainty. Dehydration risk is compounded.
Evidence: FDA label (Zepbound 2025) + mechanistic
SSRI/SNRI
-
Mescaline and Pristiq (desvenlafaxine) Clinician Review
No direct pairing evidence. Pristiq raises BP and has seizure caution. Mescaline adds autonomic load and sympathomimetic cardiovascular effects.
Evidence: FDA label (Pristiq 2017) + mechanistic
-
