Question 1

Can Saxenda cause thyroid cancer?

Accepted Answer

In animal studies, liraglutide caused thyroid tumours. It is unknown if it does in humans. Saxenda is contraindicated if you have a personal or family history of medullary thyroid carcinoma.

Question 2

What should I do if I have severe vomiting?

Accepted Answer

Stop your next dose and contact your doctor. Severe vomiting can lead to dehydration and kidney problems. They may advise you to pause treatment or manage with anti‑sickness medication.

Question 3

Can I drink alcohol while on Saxenda?

Accepted Answer

Alcohol isn't prohibited, but it can worsen nausea, dizziness, and may increase the risk of low blood sugar if you also take diabetes medication. It's best to limit alcohol, especially in the first few weeks.

Question 4

Does Saxenda interact with birth control pills?

Accepted Answer

No direct interaction. However, severe vomiting or diarrhoea could reduce absorption of oral contraceptives. Use additional protection (e.g., condoms) if you have significant gastrointestinal side effects.

Question 5

How long does nausea last with Saxenda?

Accepted Answer

For most people, nausea is worst during the first few weeks and after each dose increase. It typically improves within 1‑2 weeks per dose level, and often disappears once on the maintenance 3.0 mg dose.
