You’ll start by taking PALYNZIQ once a week. You’ll self-inject PALYNZIQ just under the skin (subcutaneously). Then, your clinic team will adjust your dose based on how you respond to treatment.
PALYNZIQ comes in prefilled syringes and is available in 3 dosage strengths:
The needle used for PALYNZIQ injections is just a half an inch long. It is injected right under the skin (subcutaneously). This can make it less painful than a flu shot, which is injected into your muscle.

Before injecting PALYNZIQ, talk to your healthcare provider right away if you cannot or will not use auto-injectable epinephrine to treat a severe allergic reaction. If you are pregnant or plan to become pregnant while taking PALYNZIQ, talk to your healthcare provider to discuss the risks and benefits of taking PALYNZIQ during pregnancy to you and your unborn baby. If you are breastfeeding or plan to breastfeed, talk to your healthcare provider to discuss the risks and benefits of taking PALYNZIQ while breastfeeding for you and your baby.
*You must carry your auto-injectable epinephrine with you at all times.
Because of the unique way PALYNZIQ works, it can cause a reaction. When a new treatment enters the body, the immune system doesn’t know what it is and may react to it. This reaction is called a “hypersensitivity event.”
A severe allergic reaction (anaphylaxis) is a type of hypersensitivity event that may be life-threatening and can happen at any time during treatment with PALYNZIQ.
Your clinic team will prescribe autoinjectable epinephrine in case you experience a severe allergic reaction.
They will also train you about how to recognize the signs of a severe allergic reaction so you can be prepared to manage it if it happens.
These signs include:
In clinical trials, about 1 in 2 people who experienced a severe allergic reaction used an autoinjectable epinephrine pen to manage it. If you experience any of these symptoms, reach out to your clinic team right away.
Remember: If you do have a serious allergic reaction with PALYNZIQ, it doesn’t always mean it will happen again. It also does not mean you need to stop taking PALYNZIQ.
Change (rotate) your injection site and check your injection site for redness, swelling, or tenderness before each injection. Tell your healthcare provider right away if you develop signs or symptoms of an infection at your injection site that are new, do not go away, or get worse.
