Can I restart Saxenda after stopping treatment? Yes, you can restart Saxenda (liraglutide 3.0 mg) after a break, but only under medical supervision and following the proper dose escalation schedule. Saxenda is a glucagon-like peptide-1 (GLP-1) receptor agonist licensed in the UK for weight management in adults with obesity or overweight with comorbidities. If you've stopped taking Saxenda—whether due to side effects, cost, pregnancy, or other reasons—restarting requires careful medical assessment and gradual dose titration to minimise gastrointestinal symptoms. This article explains when and how to safely restart Saxenda, what to discuss with your GP, and the clinical considerations that determine whether restarting is appropriate for you.

Can You Restart Saxenda After Stopping Treatment?

Yes, it is possible to restart Saxenda (liraglutide 3.0 mg) after stopping treatment, though this decision should always be made in consultation with your GP or prescribing healthcare professional. Saxenda is a glucagon-like peptide-1 (GLP-1) receptor agonist licensed in the UK for weight management in adults with a body mass index (BMI) of 30 kg/m² or greater, or 27 kg/m² or greater with weight-related comorbidities such as type 2 diabetes or hypertension.

When restarting Saxenda, you cannot simply resume at your previous maintenance dose. The medication must be reintroduced using the same gradual dose escalation schedule that was followed when you first began treatment. This titration protocol is essential to minimise gastrointestinal side effects such as nausea, vomiting, and diarrhoea, which are common when starting or restarting GLP-1 receptor agonists. The standard escalation involves starting at 0.6 mg daily and increasing by 0.6 mg increments weekly until reaching the maintenance dose of 3.0 mg daily, provided each dose is tolerated.

Importantly, if more than 3 days have passed since your last Saxenda injection, you must restart at 0.6 mg and follow the titration schedule again, as directed in the Saxenda product information.

There is no official contraindication to restarting Saxenda after a treatment break, but your healthcare provider will need to reassess your suitability for the medication. This includes reviewing your current weight, any changes in your medical history, concurrent medications, and whether you experienced any adverse effects during your previous course of treatment. According to the Saxenda product information, treatment should be discontinued if at least 5% of initial body weight has not been lost after 12 weeks on the 3.0 mg daily dose. For NHS prescriptions, NICE Technology Appraisal (TA664) sets specific eligibility criteria and limits treatment duration to a maximum of 2 years.

Reasons People Stop and Restart Saxenda Treatment

Understanding why people discontinue Saxenda can help inform decisions about restarting treatment. Gastrointestinal side effects are the most common reason for stopping Saxenda, particularly nausea, which affects approximately 39% of users according to clinical trials. Other frequent adverse effects include diarrhoea, constipation, vomiting, and abdominal discomfort. Whilst these symptoms often improve after the first few weeks as the body adjusts to the medication, some individuals find them intolerable and choose to discontinue treatment.

Cost considerations represent another significant factor, as Saxenda is available on NHS prescription only for patients meeting specific NICE TA664 criteria (including a BMI threshold, presence of pre-diabetes or high risk of cardiovascular disease, and engagement with a weight management service). Many patients require private prescription, costing several hundred pounds monthly. Financial constraints may lead to treatment interruptions, with some patients hoping to restart when circumstances improve. Additionally, some people stop Saxenda after achieving their target weight loss, believing they can maintain their results through lifestyle measures alone, only to find weight regain prompts consideration of restarting.

Other reasons for discontinuation include:

• Pregnancy planning or pregnancy — Saxenda is contraindicated during pregnancy and should be stopped before conception; effective contraception should be used during treatment

• Personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia syndrome type 2 — specialist advice is recommended in these cases

• Inadequate weight loss response — if less than 5% weight loss after 12 weeks at maintenance dose

• Surgical interventions or acute illness requiring temporary cessation

• Medication interactions or changes in other health conditions

• Development of gallbladder disease or pancreatitis, which may necessitate stopping treatment

People may wish to restart Saxenda after addressing the initial reason for stopping, such as completing pregnancy and breastfeeding, resolving financial barriers, or after weight regain following initial success. It is essential to have realistic expectations — restarting Saxenda does not guarantee the same degree of weight loss achieved previously, and long-term weight management requires sustained lifestyle modifications alongside any pharmacological intervention.

How to Safely Restart Saxenda Treatment

Restarting Saxenda safely requires following the same dose escalation protocol used when initiating treatment for the first time. This gradual titration schedule is not optional — it is a critical safety measure designed to improve tolerability and reduce the risk of gastrointestinal adverse effects. The standard escalation regimen approved by the MHRA involves:

• Week 1: 0.6 mg once daily

• Week 2: 1.2 mg once daily

• Week 3: 1.8 mg once daily

• Week 4: 2.4 mg once daily

• Week 5 onwards: 3.0 mg once daily (maintenance dose)

Each dose increase should only proceed if the current dose is tolerated. If you experience significant nausea or other gastrointestinal symptoms, your healthcare provider may recommend remaining at the current dose for an additional week before escalating further. Never attempt to restart at your previous maintenance dose, as this significantly increases the risk of severe nausea, vomiting, and potential dehydration. If you've missed more than 3 consecutive days of Saxenda, you must restart at 0.6 mg and re-titrate according to the schedule.

Before restarting Saxenda, your prescriber should conduct a comprehensive review including measurement of current weight and BMI, assessment of cardiovascular risk factors, review of current medications for potential interactions, and screening for any precautions. Blood tests may be appropriate, particularly checking renal function, as Saxenda can cause dehydration through gastrointestinal effects, which may impact kidney function. If you have type 2 diabetes and take insulin or sulfonylureas, dose adjustments of these medications may be needed to reduce the risk of hypoglycaemia.

Practical measures to improve tolerability when restarting include:

• Inject at the same time each day, preferably when you can rest if nausea occurs

• Start with smaller, more frequent meals rather than large portions

• Avoid high-fat foods which can exacerbate gastrointestinal symptoms

• Stay well hydrated, particularly if experiencing nausea or diarrhoea

• Rotate injection sites (abdomen, thigh, or upper arm) to reduce injection site reactions

Contact your GP immediately if you experience severe abdominal pain (particularly if radiating to the back), persistent vomiting preventing fluid intake, signs of pancreatitis, severe right upper quadrant pain with fever or jaundice (possible gallbladder disease), or if you notice a lump in the neck, hoarseness, or difficulty swallowing. Suspected side effects can be reported via the MHRA Yellow Card scheme at yellowcard.mhra.gov.uk.

Speaking to Your GP About Restarting Saxenda

Arranging a consultation with your GP or prescribing healthcare professional is essential before restarting Saxenda. This appointment allows for proper medical assessment and ensures restarting treatment is safe and appropriate for your current circumstances. Come prepared to discuss why you originally stopped Saxenda, how long you have been off the medication, any weight changes since discontinuation, and your goals for restarting treatment.

Your healthcare provider will need to reassess your eligibility according to NICE Technology Appraisal (TA664) if seeking NHS prescription. This guidance recommends liraglutide for weight management only as part of a comprehensive programme including dietary modification, increased physical activity, and behavioural strategies. For NHS treatment, specific criteria must be met, including a BMI threshold, presence of pre-diabetes or high cardiovascular risk, and engagement with a weight management service. NHS treatment is limited to a maximum of 2 years. They will evaluate whether your BMI still meets prescribing criteria (≥30 kg/m² or ≥27 kg/m² with comorbidities) and whether you have engaged with lifestyle interventions. Be honest about your adherence to dietary and exercise recommendations, as Saxenda is most effective when combined with sustained lifestyle changes.

Key topics to discuss with your GP include:

• Any new medical conditions or medications since you last took Saxenda

• Previous side effects experienced and how they were managed

• Personal or family history of thyroid conditions requiring specialist advice

• Current or planned pregnancy (Saxenda is contraindicated)

• Realistic weight loss expectations and timelines

• Monitoring arrangements and review schedule

• Funding arrangements if prescribing privately

• Safe disposal of used injection pens and needles

Your GP should establish clear treatment goals and review points. According to the Saxenda product information, treatment should be discontinued if less than 5% weight loss is achieved after 12 weeks at the maintenance dose. Regular monitoring typically includes weight measurements, blood pressure checks, and assessment of weight-related comorbidities. Your prescriber should also discuss the importance of long-term weight management strategies, as stopping Saxenda often leads to weight regain without sustained lifestyle modifications.

If your GP is unable to prescribe Saxenda through the NHS due to you not meeting NICE criteria, they may refer you to a specialist tier 3 or 4 weight management service or discuss private prescription options. Never purchase Saxenda from unregulated online sources, as counterfeit medications pose serious health risks and lack proper medical oversight.
