The Main Side Effects of Nevolat

Nevolat contains liraglutide, a GLP-1 agonist in the same drug class as Semaglutide (the active ingredient in Wegovy). Gastrointestinal issues are common among people using GLP-1 medications, with a large percentage of users reporting nausea, vomiting, and diarrhoea. Fortunately, most Nevolat side effects are temporary and can be alleviated with small lifestyle adjustments.

However, in rarer cases, Nevolat treatment can trigger more serious side effects that may indicate deeper health problems. If you do find yourself struggling with the side effects of Nevolat, it’s essential to consult our clinicians for advice, as the medication may not be suitable for your circumstances. 

Common Side Effects of Nevolat

Digestive problems are among the most common side effects of Nevolat. At least 10% of Nevolat users are affected by:

• Nausea
• Vomiting
• Diarrhoea
• Constipation
• Headaches
• Heartburn
• Difficulty sleeping (insomnia)
• Pain, irritation, itching, or rashes around the injection site

Liraglutide, the active ingredient in Nevolat, lowers blood sugar and can increase your risk of hypoglycemia. This most often affects people who take Nevolat alongside other diabetes medications, such as insulin or sulfonylureas. The warning signs of hypoglycemia (low blood sugar) are:

• Irregular heart rate
• Changes in vision
• Inability to speak clearly
• Sleepiness
• Irritability
• Anxiety
• Confusion
• Shakiness
• (In severe cases) seizures or loss of consciousness

Uncommon Side Effects of Nevolat

Uncommon side effects of Nevolat are thought to affect up to 1% of people and may require medical attention. These include:

• Dehydration (possibly due to vomiting and diarrhoea)
• Gallbladder inflammation
• Delayed emptying of the stomach
• Allergic reactions
• Rapid pulse
• Feeling generally unwell

Rare Side Effects of Nevolat

Rare Nevolat side effects are only observed in about 1 in every 1000 patients, but they require urgent medical attention. These are:

• Reduced kidney function and kidney failure
• Severe allergic reactions (anaphylaxis)
• Inflammation of the pancreas (pancreatitis)

Always speak to a healthcare professional if your side effects are particularly uncomfortable or persistent.

How to Manage Nevolat Injection Side Effects 

In many cases, the side effects of Nevolat are temporary. They tend to flare up at the start of treatment and during dose increases, but usually ease off over time. You can further alleviate digestive problems caused by Nevolat with small dietary changes, such as:

• Eating smaller portions at mealtimes
• Only eating when hungry and stopping when full
• Avoiding fatty and spicy foods
• Avoiding alcohol and carbonated drinks
• Increasing fibre and water intake to combat constipation
• Increasing fluid intake to reduce the risk of dehydration

Severe or persistent gastrointestinal issues should always be discussed with a clinician. They may suggest the use of over-the-counter remedies, such as anti-vomiting or antidiarrhoeal medicine. They may also recommend a slower dose escalation plan, as nausea and other side effects often coincide with dose increases.

When Do the Side Effects of Nevolat Appear?

Gastrointestinal issues caused by Nevolat often begin within the first few weeks of treatment, and may begin as early as the day of your first dose. Dehydration is also most likely to occur at the start of treatment, possibly due to vomiting and diarrhoea.

Side effects can also return when you increase your dose, but typically pass as your body adjusts to the medication. If you experience digestive problems on Nevolat, following the advice listed above may help to alleviate your symptoms. However, it is always advisable to consult a healthcare professional if your symptoms persist or do not improve.

How Long Do Nevolat Side Effects Last?

Nevolat side effects are typically temporary, and affect most people at the start of treatment and during dose increases. They usually improve within days or weeks, and may be alleviated by making certain adjustments to your diet. Some people may not even experience any side effects of Nevolat at all.

How Nevolat Side Effects Compare to Other Weight Loss Treatments

Nevolat contains liraglutide, which belongs to a class of drugs called GLP-1 agonists. Other GLP-1 agonists include tirzepatide (the active ingredient in Mounjaro) and semaglutide (found in Wegovy).

All GLP-1 agonists cause similar side effects, the most common of which are gastrointestinal problems. The main side effects of Nevolat, Mounjaro and Wegovy are nausea, vomiting, diarrhoea, and constipation, and these occur at similar rates with all three medications.

The uncommon and rare side effects of Nevolat, Mounjaro, and Wegovy include pancreatitis, gallbladder problems, kidney problems, allergic reactions, and hypoglycemia. These affect a far smaller number of people, but shouldn't be overlooked as they can have serious health consequences. If you experience any side effects with Nevolat, consult a clinician for advice.

Is Nevolat Safe to Take With Other Medications?

If you already take medication, you will need to consult a clinician before starting Nevolat treatment. This is because Nevolat can interact with other medicines in ways that may cause health problems.
For example, Nevolat lowers blood sugar. Taking it alongside other GLP-1 agonists or antidiabetic drugs can produce a sharp drop in blood glucose levels and may result in hypoglycemia.

Can Nevolat Cause Blindness?

While there may be an association between the use of GLP-1 agonists and vision loss, there is no evidence to suggest that Nevolat causes blindness. The link potentially comes from the fact that liraglutide is frequently prescribed to individuals with type 2 diabetes, a leading cause of blindness. This may account for reports of vision loss among people using Nevolat.

Instead of damaging your eyesight, it’s possible that Nevolat may even reduce the risk of blindness in people with type 2 diabetes.

Does Nevolat Cause Acne?

Some Nevolat users report outbreaks of acne during treatment, but GLP-1 agonists are not necessarily bad for your skin. Research has not found any evidence of a direct link between Nevolat (or other GLP-1 agonists) and the development of acne. Instead, the weight loss caused by these medications may trigger hormonal changes in the body, which can contribute to the development of spots.

Are the Side Effects of Nevolat and Saxenda the Same?

Because Nevolat and Saxenda contain the same active ingredient, liraglutide, both medications would cause the same side effects. While both treatments support weight loss in similar ways and have comparable dosing schedules, they cannot be considered identical to one another.

To learn more about the similarities and differences between Nevolat and Saxenda, please read our comprehensive comparison article.
