• Minimal side effects
• Good quality of life
• Adequate nutrition intake

Personalized Dosing

• Response to medication

Managing Side Effects at Each Level

Low Doses (2.5mg-5mg)

Focus on eating smaller meals

Stay hydrated

Medium Doses (7.5mg-10mg)

Side effects typically stable

Dietary management important

May need anti-nausea strategies

High Doses (12.5mg-15mg)

Monitor nutrition carefully

Protein supplements if needed

Regular check-ins with provider

Extended Dosing (Beyond 15mg)

Compounded Higher Doses

Some compounding pharmacies offer:
• 20mg
• 30mg

Considerations:
• Not FDA-approved doses
• Less safety data
• Requires medical supervision
• May increase side effects
• Reserved for specific cases

When Higher Doses Might Be Considered

Significant weight to lose

Plateau at standard doses

Under close medical supervision

After thorough risk-benefit analysis

Splitting Doses

Why Some People Split

Reduce side effect intensity

More consistent medication levels

Better tolerance

How to Split

Instead of 10mg once weekly:

5mg twice weekly (every 3-4 days)

Common Dosing Questions

Can I skip the 2.5mg dose?

Not recommended. Starting higher increases side effect risk and doesn't speed overall results.

What if I miss a dose?

Take it within 4 days of scheduled dose

If more than 4 days late, skip and resume normal schedule

Never double up

Can I stay at a low dose permanently?

Yes, if you're getting good results with minimal side effects, there's no requirement to increase.

How long before I see results?

Week 1-4: Minimal (adjustment phase)

Week 5-8: Beginning weight loss

Month 3+: Significant results typically visible

Transitioning Between Doses

Tips for Smooth Transitions

Increase on consistent schedule

Note how you feel at each level

Don't increase if struggling with current dose

Give each dose at least 4 weeks

If New Dose Is Difficult

Continue for 2-3 weeks if bearable

Use all side effect management strategies

Consider going back to previous dose

Discuss with healthcare provider

Dose Tracking

Keep a record of:
• Current dose
• Date of any changes
• Weekly weight
