The short answer for most patients: yes, take your medications as usual. Ultrasound is a non-invasive imaging test that doesn't interact with drugs the way some procedures do.
The General Rule
Unlike surgery or certain contrast-based scans, ultrasound has no drug restrictions. Blood pressure tablets, thyroid medication, antibiotics, supplements — all can typically be taken on schedule with a small sip of water, even if you're fasting for an abdominal scan.
Special Situations to Discuss With Your Clinic
- Diabetic patients: If you've been asked to fast, your insulin or oral diabetes medication timing may need adjusting to avoid low blood sugar. Call your doctor or the clinic in advance — never skip diabetes medication without guidance.
- Diuretics ("water pills"): If you need a full bladder for a pelvic scan, a diuretic might work in your favour — but mention it so timing can be planned.
- Medications taken with food: If fasting is required and your medication must be taken with food, ask whether to delay the dose until after the scan.
What to Bring
Bring a current list of your medications to your appointment. It helps the sonographer and reporting doctor interpret certain findings — for example, some drugs affect gallbladder or kidney appearance.
Key takeaway: Don't stop any prescribed medication for an ultrasound unless a healthcare professional specifically tells you to.
