Your healthcare provider will show you how to use Saxenda. The following is a guide.

Prefilled pen

Saxenda is a pre-filled, dial-a-dose pen. This means that the pen contains an amount of medicine already loaded (18 mg of liraglutide). Depending on the dose you dial, it can deliver amounts of 0.6 mg, 1.2 mg, 1.8 mg, 2.4 mg and 3 mg.

Time of day

A Saxenda injection is given once a day. You can use Saxenda at any time of day, with or without food. It's best to inject Saxenda at about the same time each day, at a time that is most convenient for you.

Needles 

Saxenda pre-filled pens are designed to be used with NovoFine® needles of up to 8 mm long. Needles are not included with the pen. Ask your doctor or nurse which needle width (gauge) and length is best for you. Use a new needle for each injection and dispose of it after use. 

Injection site

Saxenda is given as an injection under your skin (subcutaneous injection) as shown to you by your doctor or nurse. Saxenda may be injected into the front of your waist (abdomen), the front of your thigh or your upper arm. Don't inject Saxenda into a vein or muscle. 

Missed dose

If you miss a dose of Saxenda and the next dose is less than 12 hours away, skip the missed dose and carry on as normal. If it's more than 12 hours until the next dose, take the missed dose as soon as you remember. Don't take 2 doses at the same time.

For more information on how to use the Saxenda pen, see the Medsafe consumer information sheet on Saxenda(external link) or watch this video(external link).

Here are some things to know when you're using Saxenda. Other things may be important as well, so ask your healthcare provider what you should know about.

Drink enough water to avoid dehydration

When starting Saxenda, it can cause nausea (feeling sick), vomiting (being sick) and diarrhoea (runny poo) that can last for a few days. This increases your risk of dehydration, which can cause serious kidney problems. Be sure to drink plenty of water or non-sugary beverages. Avoid alcohol, as it can affect your blood glucose. Contact your healthcare provider if you have nausea, vomiting and diarrhoea or get symptoms of dehydration such as headache, feeling lightheaded or dizzy, weakness, feeling very tired, no energy and peeing (urinating) less than usual.

If you are unwell

Saxenda doesn't usually cause problems if you're slightly unwell, but if you're dehydrated from vomiting and diarrhoea and not eating and drinking as usual, you can delay the next injection until you're better. Talk to your healthcare provider if you have any questions.

Pregnancy and contraception

If you're pregnant, think you may be pregnant, or are planning to have a baby, ask your healthcare provider for advice as Saxenda is not recommended during pregnancy.

Research has found that weight loss may increase the likelihood of some women returning to normal ovulation. If you're sexually active and don't want to become pregnant, you should use effective contraception to avoid unplanned pregnancy. Read more about contraception.

How to store Saxenda

• Before opening: Store Saxenda in the fridge, in the original package. Do not freeze. If your pen has been frozen, don't use it.
• During use: You can keep the pen for 1 month when stored at room temperature (below 30°C) or in a refrigerator (2°C to 8°C). Don't freeze it. 

When you're not using the pen, keep the pen cap on to protect it from light.

Get rid of your used needles safely

It's important to get rid of your used needles safely. Keep them out of reach of children and pets, and places where they could hurt others. You can do this by buying a sharps container from your pharmacy. This is a special container made of hard plastic that has a tight-fitting lid so used needles and syringes can be stored securely.

Don't flush used needles down the toilet or put them in household or public rubbish or recycle bins. Once your sharps container is full, take it to your pharmacy for safe disposal.

Like all medicines Saxenda can cause side effects, although not everyone gets them. If you're concerned about any symptoms you think might be related to your medicine, talk to your healthcare provider. The following information offers some guidance but doesn't include all possible side effects.

Common side effects

Tell your healthcare provider if any of these side effects bother you.

• Reaction at the injection site such as bruising, redness, tenderness: Remember to change the injection site every day. You can use the same part of your body but try not to use exactly the same spot. Avoid injecting Saxenda cold, because it's more likely to sting.
• Nausea (feeling sick), diarrhoea (runny poo), constipation, indigestion, gas or bloating: If you have diarrhoea or are dehydrated, delay your next dose until you feel better and are eating and drinking normally.
• Tiredness, headache, dehydration, feeling thirsty: Make sure you're drinking enough water. If you're dehydrated, delay your next dose until you feel better and you're eating and drinking normally.
