Will an antihistamine make me drowsy?
Second generation antihistamines (often referred to as non-sedating antihistamines), such as Telfast, offer relief from hayfever symptoms quickly, easily and without drowsiness. Antihistamines that have a sedating effect, not only cause drowsiness, but also can slow reaction time and reduce concentration. This more subtle effect of sedation is called impairment. Driving while sedated is dangerous. The driver may feel noticeably drowsy; may have impaired coordination and slowed reactions. That is why some antihistamines carry a sedation warning on their pack. Always read the label carefully. In studies, subjects taking Telfast have reported drowsiness at a similar rate to placebo.
Telfast is a non-sedating antihistamine and does not carry a sedation warning.
Do I really have to get rid of my pet?
You can always try keeping the pet outside, however generally the only effective avoidance measure is to remove the pet from the home altogether.
If I have allergies will my child?
Family history of allergic disease is an identified risk factor for a child developing an allergy; however, it is possible to take steps to minimise allergies developing in children. The Australian Society of Clinical Immunology and Allergy offers helpful advice on ways to achieve this.
Do I need a prescription to treat my allergies?
No, you do not always necessarily need a prescription. First line therapy for treating hayfever is available over the counter; however, it is always a good idea to seek a doctor or pharmacists opinion of your condition. If your symptoms persist you should seek further advice form your healthcare professional and they may recommend a treatment that may require a prescription.
If I am an asthmatic, should I avoid taking a steroid nasal spray?
As the steroids are localised to the nose, the dose absorbed by the blood is small, lessening concerns of steroid side effects. If patients are being treated for asthma or eczema, the total steroid load should be considered. Asthmatics should consult their doctor for advice on managing asthma and allergies.
What is urticaria?
Hives (sometimes called urticaria) are red, raised wheals on the skin, which are intensely itchy and are another example of an allergic reaction. Instead of the upper respiratory area displaying symptoms for a hayfever sufferer, for someone with hives it is the skin that indicates symptoms.
Urticaria can be ‘acute’ where the hives develop very suddenly, last a short while and then disappear, or ‘chronic’, where it is persistent and long lasting. The swellings themselves can be small (like mosquito bites) or large, measuring several centimetres.
Hives can appear anywhere on the body and may be scattered over more than one area. In severe cases, the whole face and body may be covered with inflamed, itchy skin bumps or blotches.
Are all antihistamines the same?
There are differences between antihistamines. These differences include; whether it causes drowsiness or not, how quickly they work and how long they last. Some antihistamines will work better for some people than others. Ask at your pharmacy for a recommendation if you are unsure.
