Should you stop taking Ozempic if your Libre 3 CGM is showing low blood sugar readings?
Please don't stop or adjust Ozempic without speaking to your doctor first — that's a really important step here. CGM readings can sometimes be inaccurate, and there are a few reasons your Libre 3 might be showing false lows.
Here are some common causes of inaccurate CGM readings:
- Sensor placement or compression — pressure on the sensor (like sleeping on it) can cause false lows
- Dehydration — this can skew glucose readings lower than they actually are
- Expired or poorly stored test strips (if also using a traditional meter)
- Extreme temperatures — heat or cold can affect sensor accuracy
- Certain medications or supplements — some can interfere with readings To check whether the low reading is real, try these steps:
1. Confirm with a fingerstick using a traditional glucose meter
2. Wash and dry hands thoroughly before the fingerstick test
3. Check how you feel — symptoms like shakiness or sweating may confirm a true low
4. Contact your doctor if readings consistently seem off, especially while on Ozempic
If you're genuinely experiencing low blood sugar symptoms, seek medical help right away. But if you feel completely fine and the fingerstick shows a normal reading, the sensor may simply need recalibrating or replacing. Your doctor can help sort out whether Ozempic needs any adjustment.
