Titration: What You Need To Know About Increasing Your GLP-1 Treatment Dosage

Article Summary:

• Titration is the process of safely and gradually increasing your medication dose over time, while monitoring how your body responds.
• GLP-1s (like Mounjaro and Wegovy) are hormone-based treatments. Titration is applied to their treatment, to help maximise their efficacy and minimise side effects.
• In consultation with a healthcare professional, you can increase your dose once every 4 weeks as long as you're tolerating your dose and your side effects are manageable.

What is titration?

In medicine, titration is the process of safely and gradually increasing your medication dose over time. It's often used for medications which affect nerve or hormonal pathways, like metformin for type 2 diabetes and diuretics for high blood pressure. [1] [2] [3] And, as we'll learn, it's also used in certain types of weight loss treatments.

How does titration work?

Titration helps you find the best medication dosage for your needs. Ideally, this means balancing maximum effectiveness and minimising potential side effects, while giving your body the time it needs to adjust to your medication. [4]

Titration and weight loss injections

Weight loss injections like Mounjaro and Wegovy are hormone-based treatments. These Glucagon-like Peptide-Receptor Agonists (GLP-1s) work by acting just like your natural GLP-1 hormone, to regulate your appetite and increase satiety (feeling 'full'). [5] [6] This may help to minimise food cravings, prevent overeating and, over time, reduce your body weight. [5] [6]

GLP-1 medications, like Wegovy and Mounjaro, follow a structured titration schedule to ensure a smooth transition. However, dosing varies by medication:

Mounjaro

The starting dose for Mounjaro (tirzepatide) is 2.5 mg, taken once a week for four weeks. After 4 weeks, your dose may increase to 5 mg once a week. [5]

Your dose may increase by 2.5 mg increments, to 7.5 mg, 10 mg, 12.5 mg or 15 mg, taken once a week. This depends on how well you're tolerating the side effects of your dose. In each case, your healthcare provider will tell you to stay on a particular dose for at least 4 weeks before going to a higher dose. [5] For more information, please refer to your patient information leaflet or speak to your healthcare professional.

Wegovy

The starting dose for Wegovy (semaglutide) is 0.25 mg, taken once a week. [6] This dose is gradually increased every 4 weeks, over 16 weeks of treatment. You may be able to gradually increase your dose every 4 weeks until you reach the dose of 2.4 mg once weekly.

If you're living with obesity, you may be able to increase your dose to the maximum dose of 7.2 mg (3 injections of 2.4 mg), taken once weekly. This can be made after a minimum of 4 weeks on 2.4 mg. For more information, please refer to your patient information leaflet or speak to your healthcare provider. [6]

Why do I start treatment on a lower dose?

Your treatment starts on a lower dose to help your body adjust to your new medication. It'll also help to minimise side effects. Increasing your dosage too quickly may make side effects worse. [7]

Digestive side effects are common when you start weight loss medication. When taking GLP-1 agonists, these most often include diarrhoea and nausea. [8] Fortunately, these side effects are often mild, and usually go away by the time you reach your maintenance dose. [9] However, there are also rarer, but more serious side effects to be aware of, like an allergic reaction. [5] [6]

For a full list of common and rare side effects, please refer to your patient information leaflet.

How frequently does titration happen when taking weight loss injections?

If you're taking a GLP-1 medication, you can increase your dose once every 4 weeks as long as you're tolerating your dose and your side effects are manageable.

At MedExpress, our team is here to guide you on dosage increases. We'll send you regular medicine reminders via email and, during each check-in, your practitioner will assess how you're responding to your medication, as well as the severity of any side effects. If they think you're ready to increase your dose, they'll let you know. Your increased dose will then be delivered with your next order.

You’ll continue increasing your dose every four weeks until you reach your maintenance dose.

What's a maintenance dose?

Your maintenance dose refers to the dose that provides the best results, while keeping side effects manageable. This may be the maximum recommended dose for your treatment, or it could be a lower dose that minimises any uncomfortable side effects you're experiencing. [10]

In short, it's the dose that feels right for you and your body.

How do I know if I'm ready to increase my dose?

You may want to increase your dose if:

• Your weight loss has stayed the same for several weeks, despite lifestyle changes like a reduced calorie diet and increased physical activity.
• 'Food noise' has returned, and you're increasingly noticing cravings, thinking about food all the time, or less feelings of fullness.
• You're experiencing little to no side effects. If you've passed the 4-week adjustment period and your side effects have subsided, you may feel ready to increase your dose. Speak to your healthcare provider to check if this is possible. [11]

What if I want to switch weight loss treatments?

You may be able to switch from one form of weight loss medication to another as long as it's done with the approval of a health care professional. Some people decide to change due to side effects, or because one treatment’s more cost-effective than another.

But before you do switch, it might be worth exploring a lower dose of your current medication first. If you’re swapping from one type of weight loss injection to another because of side effects, you may still notice similar adverse reactions (like nausea and diarrhoea). This is because GLP-1 drugs like Mounjaro and Wegovy work in a similar way.

Whether you decide to switch or stay with your current medication, for best results keep your weekly injection schedule consistent. And, if you have any concerns about your progress, speak to your healthcare provider. They're there to support you during your weight loss and weight management journey.

Important information about titration

GLP-1 use must always be done with the approval of a certified healthcare professional. They’ll be able to monitor your progress and provide clinical guidance on unwanted reactions and side effects.

Be sure to read and follow the information provided in your patient information leaflet. This will arrive with each pen, and will also include detailed injection instructions.

And remember that any weight loss treatment works best alongside positive and sustainable lifestyle changes. These include a reduced calorie diet, increased physical activity and, ideally, 7-9 hours’ sleep a night. Having a weight management plan in place may help you maintain a healthy body weight beyond your treatment. [12]
