2.5mg Dose FAQs
How long do I stay on 2.5mg?
You should use the 2.5mg dose for exactly 4 weeks (4 once-weekly injections). After this, you'll increase to 5mg. The 2.5mg dose is not meant for long-term use.
Can I skip 2.5mg and start on 5mg?
No. Always start with 2.5mg regardless of your weight or previous medication experience. Starting at higher doses significantly increases the risk of side effects without improving results.
How many pens do I need for 4 weeks?
You need 1 pen only. Each 2.5mg pen contains 4 doses (injections), which equals 4 weeks of treatment. This is often confused - you do NOT need "4 pens."
Will I lose weight on 2.5mg?
Most people experience modest weight loss (1-3kg) during the 2.5mg phase. However, this is primarily a tolerance-building dose. More significant weight loss occurs at 5mg and higher.
What if I experience side effects?
Mild nausea, fatigue, or digestive issues are common and usually improve within 2-3 weeks. Stay hydrated, eat smaller meals, and contact your prescriber if symptoms are severe or persistent.
