Bilastine 20 mg guide
How to take bilastine away from food and fruit juice, assess drowsiness, and distinguish allergy symptoms from an emergency.
Mode d'emploi
- 01
Étape 1
Take 20 mg once daily on an empty stomach
Take one tablet with water, one hour before or two hours after food or fruit juice. Food and fruit juice reduce absorption, so keep the interval every day.

Étape 2
Check your own alertness
Bilastine is less sedating for many people but can still cause drowsiness or dizziness. Learn your response before driving or using machinery and avoid taking an extra antihistamine unless advised.
Calendrier posologique
- 01
Étape 1
Once daily during the prescribed period
Use the same fasting interval each day. If a dose is missed, take the next dose at the normal time rather than doubling.

Étape 2
Review symptom control
Track nasal, eye, or skin symptoms, triggers, and drowsiness. Persistent symptoms may need a diagnosis review or additional local treatment, not a higher bilastine dose without advice.
Effets secondaires
Headache and drowsiness
Headache and sleepiness are among the more common effects. Dizziness, tiredness, abdominal discomfort, or nausea can also occur.
Heart-rhythm caution
People with rhythm risk, low electrolytes, significant bradycardia, or QT-prolonging medicines need an individual review. Report new palpitations or fainting.
04 · Quand contacter votre médecin
Contactez votre médecin si
- Breathing difficulty, tongue or throat swelling, collapse, or rapidly progressing widespread hives — call emergency services
- Fainting, persistent palpitations, or a severe allergic reaction after the tablet
- Symptoms remain uncontrolled, drowsiness affects daily activity, or you need another antihistamine
Conservation
Keep in the original package, away from moisture and direct heat, and out of children's reach. Follow the temperature limit on your pack and do not use it after the expiry date.
À quoi s'attendre
Bilastine blocks histamine H1 receptors and can reduce symptoms of allergic rhinoconjunctivitis or urticaria while exposure continues. It does not remove the trigger and is not a treatment for anaphylaxis. Review persistent or atypical symptoms rather than escalating the dose yourself.
