4.3. Contraindications

The use of CETIZAL 5 is contraindicated in:

  • Hypersensitivity to levocetirizine or to any of the excipients of CETIZAL 5, or to any piperazine derivative.
  • Pregnancy and lactation (see section 4.6).
  • End stage renal disease (creatinine clearance <10 mL/min).
  • Infants and toddlers aged less than two years, as safety and efficacy have not been demonstrated (see also section 4.4).

4.4. Special warnings and precautions for use

Alcohol

Precaution is recommended with intake of alcohol (see section 4.5). CETIZAL 5 lacks significant sedative effects. Patients should, however be warned that a small number of individuals may experience sedation. This effect may be compounded by the simultaneous intake of alcohol or other central nervous system (CNS) depressants (see section 4.5).

Risk of urinary retention

Caution should be taken in patients with predisposing factors of urinary retention (e.g. spinal cord lesion, prostatic hyperplasia) as CETIZAL 5 may increase the risk of urinary retention.

Lactose intolerance

CETIZAL 5 contains lactose. Patients with rare hereditary problems of galactose intolerance total lactase deficiency or glucose-galactose malabsorption should not take CETIZAL 5.

Paediatric population

Children aged less than 6 years

The use of CETIZAL 5 is not recommended in children aged 2 to 6 years since the film-coated tablet does not allow for appropriate dose adaption.

Infants and children under 2 years

Data are not sufficient to support the administration of CETIZAL 5 to infants and toddlers aged less than 2 years. CETIZAL 5 is contraindicated in infants and toddlers aged less than 2 years (see see section 4.3).

4.5. Interaction with other medicinal products and other forms of interaction

No interaction studies have been performed with CETIZAL 5 (including no studies with CYP3A4 inducers). Studies with the racemate compound cetirizine demonstrated that there were no clinically relevant adverse interactions with diazepam, glipizide, ketoconazole, erythromycin, azithromycin, cimetidine and pseudoephedrine.

Alcohol

In sensitive patients, the simultaneous administration of CETIZAL 5 and alcohol or other central nervous system depressants may have effects on the central nervous system. It is advisable to avoid excessive alcohol consumption.

Theophylline

A decrease in clearance of cetirizine (16%) was reported with theophylline (400 mg once a day), while the disposition of theophylline was not altered by concomitant cetirizine administration.

Ritonavir

It was reported, with ritonavir (600 mg twice daily) and cetirizine (10 mg daily), the extent of exposure to cetirizine was increased by about 40% while the disposition of ritonavir was decreased (-11%).

Food

The extent of absorption of CETIZAL 5 is not reduced with food, although the rate of absorption is decreased.

4.6. Pregnancy and lactation

Pregnancy

CETIZAL 5 is contraindicated in pregnancy as the safety has not been established.

Breastfeeding

Levocetirizine is excreted in breast milk; therefore, CETIZAL 5 is contraindicated in lactating women.

4.7. Effects on ability to drive and use machines

Patients should be warned that CETIZAL 5 may cause somnolence, fatigue and asthenia, and therefore it may interfere with the patient’s daytime activities. This effect may be compounded by the simultaneous intake of alcohol or other nervous system depressants. It is therefore advisable to determine individual response before driving, performing complicated tasks, engaging in potentially hazardous activities or operating machinery.

4.8. Undesirable effects

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicine is important. It allows continued monitoring of the benefit/risk balance of the medicine. Health care providers are asked to report any suspected adverse reactions to SAHPRA via the “6.04 Adverse Drug Reactions Reporting Form”, found online under SAHPRA’s publications: https://www.sahpra.org.za/Publications/Index/8.
