Site Rotation:

Week 1: Left abdomen

Week 2: Right thigh

Week 3: Right abdomen

Week 4: Left thigh

Pen Mechanics:

Uses the same starter pen as 0.25 mg

No priming needed after first use

🔹 Side Effect Management
Most Common:

Nausea (35%)

Constipation (25%)

Diarrhea (15%)

Advanced Prevention:

Pre-Injection:

Ginger root 550 mg 1hr before

Ondansetron 4mg if previous nausea

Post-Injection:

Liquid meal replacement (day 1)

Electrolyte supplementation

🔹 Clinical Monitoring
Essential Labs:

A1c at 12 weeks

Fasting lipid panel

Renal function tests

Safety Checks:

Thyroid exam (baseline)

Pancreatic enzymes if symptomatic

Retinal exam if diabetic retinopathy

Prior Auth Tips:

Document failed metformin

Show elevated A1c (>7.5%)

Include BMI if >27 (comorbidity)

🔹 Special Populations
Elderly (≥65):

Slower titration recommended

Monitor hydration status closely

Renal Impairment:

No dose adjustment needed

Monitor eGFR if <30 mL/min

NAFLD Patients:

May see ALT reduction

Monitor liver enzymes

🔹 Transition Considerations
From Other GLP-1s:

Liraglutide 1.2 mg → Ozempic 0.5 mg

Dulaglutide 0.75 mg → Ozempic 0.5 mg

To Higher Doses:

After 4+ weeks at 0.5 mg

Can increase to 1.0 mg if needed
