How to time bilastine away from food and fruit juice, judge your own drowsiness before driving, and tell ordinary allergy symptoms from an emergency.
Bilastine is an antihistamine tablet for allergic rhinoconjunctivitis or
urticaria. It works best taken consistently away from food, and while it
is less sedating for many people than older antihistamines, it can still
cause drowsiness — so learning your own response matters before you drive
or use machinery.
Two rules govern this tablet, and they apply together rather than in sequence.
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 same
interval every day.
Check your own alertness
Bilastine can still cause drowsiness or dizziness. Learn your response
before driving or using machinery, and avoid taking an extra
antihistamine unless advised.
Daily dose 20 mg bilastine — one tablet, taken on an empty stomach.
Use the same fasting interval each day for the prescribed period. If a
dose is missed, take the next dose at the normal time rather than
doubling. 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.
People with rhythm risk, low electrolytes, significant bradycardia, or
QT-prolonging medicines need an individual review before taking bilastine.
Report new palpitations or fainting to your doctor.
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.
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.
Persistent or atypical symptoms should be reviewed rather than treated by
escalating the dose yourself.
