1. What Bilaxten Flas is and what it is used for
Bilaxten Flas contains bilastine as the active substance, which is an antihistamine.
This medicine is used to relieve the symptoms of allergic rhinoconjunctivitis (sneezing, nasal itching, nasal discharge, nasal congestion, and red, watery eyes) and other forms of allergic rhinitis in adults and adolescents aged 12 years and older. It can also be used to treat itchy skin rashes (hives or urticaria).
2. What you need to know before taking Bilaxten Flas
Do not take Bilaxten Flas
If you are allergic to bilastine or to any of the other ingredients of this medicine (listed in section 6).
Warnings and precautions
Consult your doctor or pharmacist before starting to use this medicine if you have moderate or severe renal impairment, low blood levels of potassium, magnesium, or calcium, if you have or have had heart rhythm problems or if your heart rate is very low, if you are taking medicines that may affect heart rhythm, if you have or have had a certain abnormal heart rhythm pattern (known as QTc interval prolongation on the electrocardiogram) that may occur in some types of heart disease and are also taking other medicines (see “Use of Bilaxten Flas with other medicines”).
Children
Do not administer Bilaxten Flas 20 mg orodispersible tablets to children under 12 years of age. For alternative pharmaceutical forms of bilastine suitable for use in children under 12 years of age, see section 3 “Use in children”.
Do not exceed the recommended dose. If symptoms persist, consult your doctor.
Other medicines and Bilaxten Flas
Inform your doctor or pharmacist if you are taking, have recently taken, or might need to take any other medicines, including those obtained without a prescription.
In particular, please discuss with your doctor if you are taking any of the following medicines:
- Ketoconazole tablets (used to treat Cushing's syndrome when the body produces excess cortisol)
- Erythromycin (an antibiotic)
- Diltiazem (used to treat angina pectoris – chest pain or pressure)
- Cyclosporine (used to reduce the activity of your immune system, to prevent transplant rejection or to reduce disease activity in autoimmune and allergic disorders such as psoriasis, atopic dermatitis, or rheumatoid arthritis)
- Ritonavir (used to treat HIV)
- Rifampicin (an antibiotic)
Taking Bilaxten Flas with food, drinks, and alcohol
These orodispersible tablets must not be taken with food or consumption of grapefruit or other fruit juices, as this would reduce the effect of bilastine. To avoid this, you may:
- take the orodispersible tablet and wait one hour before eating or drinking fruit juice, or
- if you have eaten food or drunk fruit juice, wait two hours before taking the orodispersible tablet.
Bilastine, at the recommended dose (20 mg), does not increase the drowsiness caused by alcohol.
Pregnancy, breastfeeding, and fertility
There are no data or the data are limited on the use of bilastine in pregnant women, during breastfeeding, or on effects on fertility.
If you are pregnant or breastfeeding, think you may be pregnant, or are planning to become pregnant, consult your doctor or pharmacist before using this medicine.
Consult your doctor or pharmacist before using any medicine.
Driving and using machines
It has been demonstrated that bilastine 20 mg does not affect driving performance in adults. However, individual patient responses to the medicine may vary. Therefore, assess how this medicine affects you before driving or operating machinery.
Bilaxten Flas contains sodium and ethanol
This medicine contains less than 1 mmol of sodium (23 mg) per orodispersible tablet; this is essentially “sodium-free”.
This medicine contains 0.0030 mg of alcohol (ethanol) in each orodispersible tablet, equivalent to 1.6 mg/100 g (0.0016% w/w). The amount of alcohol in an 185 mg orodispersible tablet is equivalent to less than 1 ml of beer or 1 ml of wine.
The small amount of alcohol contained in this medicine does not produce any noticeable effect.
