What should you know about new asthma biologic?

Biologics are usually given by injection or infusion and target a specific immune signal involved in airway inflammation. They are not emergency relievers and do not replace the action plan for sudden breathing difficulty.

Before starting, a specialist may review inhaler technique, adherence, blood tests, allergy features, breathing tests and the pattern of exacerbations. The choice depends on the type of inflammation and other health conditions, not on symptoms alone. [Asthma](/conditions/asthma/) can provide broader context.

Keep taking existing medicines unless your asthma team changes them. Learn the dose schedule, storage instructions and what to do if an appointment or injection is missed. Keep a record of symptoms, night waking, reliever use and activity limits so progress can be discussed.

Report new rash, swelling, fever, worsening breathing or other unusual symptoms after a dose. Ask where treatment will be given and how long you should be observed. Continue reducing smoke and irritant exposure, and keep vaccinations and routine asthma reviews on your clinician’s advice.

Call emergency services for severe breathlessness, blue or grey lips, confusion, collapse, or difficulty speaking because of breathing. Use your written asthma action plan while help is arranged.

Seek prompt medical advice for worsening wheeze, cough or chest tightness, repeated night symptoms, or increasing reliance on a reliever. A biologic works as part of a continuing plan; it does not make urgent symptoms safe to ignore.

Ask which inflammatory pattern the biologic targets, how it will be monitored, when improvement will be assessed, whether injections are self-administered, and which current medicines remain necessary.
