Common Side Effects of GLP-1 Weight Loss Injections

GLP-1 medications can cause a range of side effects, which most commonly affect the digestive system. Symptoms like nausea, bloating, constipation, diarrhoea and acid reflux are especially common when you start treatment or increase your dose, as the drugs slow stomach emptying and change your appetite signals.

While these effects are usually temporary and improve over time, they can be uncomfortable, which is why we at The Independent Pharmacy have created this unique GLP-1 Side Effects Treatment Pack to support your symptoms and help you stay on track with your weight-loss.

Loperamide Capsules For GLP-1 Side Effects: Key Info

Loperamide capsules should be taken after a loose bowel movement to help slow the bowel and improve the absorption of water, salts and sugars from the gut.

The active ingredient, loperamide hydrochloride, works by reducing intestinal muscular contractions, slowing the movement of contents through the intestines. This allows more water to be absorbed, resulting in firmer stools and less frequent bowel movements.

Ingredients

Active ingredient: loperamide hydrochloride

Other ingredients: lactose monohydrate, microcrystalline cellulose, maize starch, colloidal anhydrous silica, purified talc, magnesium stearate. The capsule is made up of gelatin, water, sodium lauryl sulfate, patent blue V (E131), quinoline yellow (E104), brilliant blue FCF (E133), iron oxide red (E172) and titanium dioxide (E171). The printing ink contains shellac (E904), propylene glycol (E1520), black iron oxide (E172) and potassium hydroxide (E525).

For the most up to date list of ingredients, please check the Patient Information Leaflet inside the box.

Side Effects

Like all medicines, loperamide can cause side effects, although not everyone gets them. Side effects can include:

  • Headache
  • Nausea
  • Constipation
  • Wind

You are less likely to experience the following side effects, but they may still occur:

  • Dizziness
  • Abdominal pain
  • Abdominal discomfort
  • Dry mouth
  • Vomiting
  • Dyspepsia
  • Rash

Warnings

Loperamide is unsuitable if you:

  • Are allergic to any of the ingredients of loperamide
  • Have a partially or completely blocked bowel
  • Are bloated or constipated
  • May have an inflamed or irritated bowel
  • Have bloody stools and a fever (these are symptoms of dysentery)
  • Have diarrhoea in response to antibiotics

Before taking loperamide, speak to your prescriber if you:

  • Have acute dysentery (such as blood in your stools and a high temperature)
  • Have AIDS and notice swelling in your stomach
  • Have liver problems

Always follow your prescriber’s advice. For all warnings and side effects, please see the Patient Information Leaflet.

Senna For GLP-1 Side Effects: Key Info

Senna contains an active ingredient derived from the senna leaf and pods, which works as a stimulant laxative. When the large intestine muscles are sluggish, too much water is absorbed causing stools to become dry and hard, resulting in difficult bowel movements. Senna works by stimulating the nerves in the gut, helping to speed up bowel movements and making stools easier to pass.

Ingredients

Active ingredients: senna fruit equivalent to 7.5mg of sennoside B

Other ingredients: calcium phosphate, maize starch, lactose monohydrate and magnesium stearate.

For the most up to date list of ingredients, please check the Patient Information Leaflet inside the box.

Side Effects

Like all medicines, senna can cause side effects, although not everyone gets them.

Common side effects include:

  • Stomach cramps
  • Abdominal pain

Warnings

Always follow your prescriber’s advice. For all warnings and side effects, please see the Patient Information Leaflet.
