Note on laboratory work, October 15, 2026. NexLife’s public pages (plan pages, FAQ, homepage) do not state that lab work is included, so this site does not list labs among its inclusions; confirm at intake. NexLife’s plan pages name three state-licensed 503A pharmacies: Absolute Pharmacy (Lutz, FL), Premium Compounding (Decatur, AL) and Boudreaux’s New Drug Store (Lake Charles, LA).
Common side effects (SURMOUNT-1 pooled data)
Nausea: ~24–31% (typically transient, peaks at dose escalation).
Boxed warning (thyroid C-cell tumors): Tirzepatide caused thyroid C-cell tumors in rats; relevance to humans is unknown. Contraindicated in patients with a personal or family history of medullary thyroid carcinoma (MTC) or multiple endocrine neoplasia syndrome type 2 (MEN-2).
Pancreatitis: Rare; discontinue if suspected.
Gallbladder events: Cholelithiasis and cholecystitis reported.
Hypoglycemia: Higher risk when combined with insulin or sulfonylureas in type 2 diabetes; dose-adjust accompanying therapy.
Acute kidney injury: Reported in association with severe GI side effects causing dehydration.
Hypersensitivity: Anaphylaxis and angioedema reported; discontinue if it occurs.
Diabetic retinopathy: Rapid A1C improvement may temporarily worsen retinopathy; monitor in patients with pre-existing retinopathy.
Contraindications
Personal or family history of medullary thyroid carcinoma (MTC).
Multiple endocrine neoplasia syndrome type 2 (MEN-2).
Known hypersensitivity to tirzepatide or any product excipient.
Pregnancy — discontinue at least 2 months before a planned pregnancy due to long half-life.
Drug interactions
Tirzepatide delays gastric emptying and may affect the absorption of orally-administered medications. The most clinically significant interaction is with oral contraceptives: Eli Lilly recommends a non-oral contraceptive method or addition of a barrier method for 4 weeks after initiation and for 4 weeks after each dose escalation. Adjust insulin and sulfonylureas in patients with type 2 diabetes to reduce hypoglycemia risk.
Managing GI symptoms during titration
Eat smaller, more frequent meals; stop eating at the first sign of fullness.
Avoid high-fat, fried, and very spicy foods during the first 1–2 weeks of each dose increase.
Hydrate — 64+ oz water daily.
For constipation: increase fiber gradually, add a stool softener if needed.
For nausea: small portions of bland food (rice, toast, broth); ginger or peppermint can help.
Communicate symptoms to your care team before any scheduled dose escalation.
When to call your clinician immediately
Severe abdominal pain (especially upper-right or upper-middle, possibly radiating to the back) — rule out pancreatitis or gallbladder event.
Persistent vomiting with inability to keep fluids down — dehydration risk.
Signs of an allergic reaction: swelling of face/lips/tongue, difficulty breathing, hives.
Sudden severe headache or visual changes.
Signs of hypoglycemia (if on insulin or sulfonylureas): sweating, shakiness, confusion.
