Does TOMAZINE cause weight gain? Newer allergy drugs, including cetirizine (TOMAZINE), fexofenadine (Telfast) and loratadine (Claritin), are less likely to cause weight gain.There are other side-effects that antihistamines like TOMAZINE will cause as well, but gaining weight is typically one people don’t expect.

Is it OK to take TOMAZINE everyday? Yes, you can take TOMAZINE daily and long term. It is an antihistamine used to treat allergy symptoms. If your symptoms are seasonal or you have allergy symptoms occasionally, then it is taken daily when required.

Can TOMAZINE cause constipation? Certain antihistamine drugs like Claritin, TOMAZINE, and Telfast that are available over the counter to treat allergy symptoms may stop you up. They belong to an even larger class of medications known as anticholinergics, which all have the possible side effect of causing constipation.

Does TOMAZINE make you drowsy? TOMAZINE contains cetirizine. It is a second-generation antihistamine. It is  less likely to make a person feel drowsy or otherwise affect alertness than older, first-generation antihistamines.

Can TOMAZINE be used for itchy skin? TOMAZINE is suitable for most hayfever allergy symptoms. It helps ease symptoms such as sneezing, itchy and runny nose and itchy throat. It is also suitable for those suffering with symptoms of itchy skin rash or hives (urticaria) associated with allergies.

Is it better to take TOMAZINE at night or in the morning? Cetirizine/ TOMAZINE can be taken at any time of the day. In most people it is non-sedating, so they take it in the morning. However, a percentage of people do find it to be sedating so if it does make you drowsy it is best to take it in the evening. TOMAZINE can be taken with or without food.


TOMAZINE is an anti-allergic agent with a histamine H1 receptor antagonism devoid of any significant anticholinergic and anti-serotonin effects. Cetirizine also reduces eosinophil recruitment induced by antigen-antibody reaction. Peak blood levels are reached within one hour after oral administration of Cetirizine. The terminal half life is approximately 10 hours in adults, 6 hours in children aged 6 to 12 years. Plasma levels are linear related to the dose given. A high proportion of Cetirizine is bound to human plasma proteins.


  • TOMAZINE is contraindicated in patients with known hypersensitivity to any of its components.
  • Not to be given for lactating women since the active ingredient is excreted in breast milk, and not in pregnancy.
  • This medication should not be used for the treatment of cough and cold symptoms in children under 6 years of age. 


Precautions and dosing adjustment is necessary in patients with moderate or sever renal impairment, dialysis patients and in patients with hepatic impairment.

Interactions with other drugs

  1. Studies with diazepam and cimetidine have revealed no evidence of interactions.
  2. No drug interactions have been found with theophylline (at low dose), azithromycin, pseudoephedrine. ketoconazole. or erythromycin.
  3. A small decrease in the clearance of Cetirizine is caused by a 400 mg dose of theophylline.
  4. Concomitant use with CNS depressants and anti-cholinergics increases their toxicity. 


Avoid driving a car, operating potentially dangerous machinery, drinking alcohol or using CNS depressants concurrently with Cetirizine, due to additional reduction in alertness and additional impairment of CNS performance.
