Fexofenadine is known as a non-drowsy antihistamine. That's because it's less likely to make you feel sleepy than drowsy (sedating) antihistamines, such as Piriton (chlorphenamine). Most people prefer to take a non-drowsy antihistamine instead of a sedating one.
Non-drowsy antihistamines, like fexofenadine and loratadine, the decongestant pseudoephedrine, and the cough suppressant dextromethorphan can cause anxiety or jitteriness, which can lead to insomnia.
You should take fexofenadine before a meal where possible. Some people find it helps to swallow the tablet with a drink of water. Try to take the tablets at the same time of day each day, as this will help you to remember to take them.
Background: Although antihistamines are known for their sedative adverse effects, fexofenadine was previously shown to have stimulating effects.
Many of the adverse events occurring in the fexofenadine hydrochloride/pseudoephedrine hydrochloride combination group were adverse events also reported predominately in the pseudoephedrine hydrochloride group, such as insomnia, headache, nausea, dry mouth, dizziness, agitation, nervousness, anxiety, and palpitation.
Common side effects include headache, dizziness, hallucinations, difficulty sleeping, fatigue, drowsiness, rapid heartbeat, dry mouth, nausea, loss of appetite, nervousness, restlessness, excitability, fear of anxiety and tremor.
Hydroxyzine is used to help control anxiety and tension caused by nervous and emotional conditions. It can also be used to help control anxiety and produce sleep before surgery.

Skip Short-Acting Allergy Meds at Night
Some medications for treating allergies, like Zyrtec (cetirizine) and Allegra (fexofenadine) last 24 hours and don't need to be taken at night.
You can take Allegra 180 mg 24 hour tablet any time of the day. You should take Allegra 60 mg 12 hour tablets twice a day, once in the morning and once at night.
Antihistamines help reduce allergic symptoms by preventing the effects of a substance called histamine, which your body produces when exposed to certain substances. Telfast is a non-sedating antihistamine which means it has been shown not to cause drowsiness.
Diphenhydramine is unlikely to cause insomnia. It typically causes drowsiness, which can help people with insomnia get to sleep. However, diphenhydramine can also stimulate the central nervous system (CNS), which could result in difficulty sleeping. It is unclear how often this occurs in people taking diphenhydramine.
While antihistamines may help you to fall asleep, overall sleep quality is usually not very good, he said. Sometimes, they even have the opposite affect and cause hyperactivity, especially in children. “Using Benadryl or any antihistamine for sleep has no long term benefit,” Alapat said.

Several studies have found cetirizine (Zyrtec) to be more effective than fexofenadine (Allegra) at relieving symptoms of allergic rhinitis and urticaria, and it appears to have a longer duration of action.
Fexofenadine, even in dosages exceeding those recommended, does not cross the blood-brain barrier to any appreciable degree, which makes it one of the least sedating of all second-generation antihistamines. Fexofenadine is considered the antihistamine of choice for people in safety-critical jobs such as airline pilots.
KYOTO, JAPAN — Fexofenadine is the sole truly nonsedating antihistamine—and the only one that does not cause objectively measurable cognitive and psychomotor impairment at doses that are commonly used in clinical practice, said Dr. Kazuhiko Yanai.
While Fexofenadine can be taken daily when your allergies are most prevalent (like during spring), you should not overuse this medication. Overuse may lead to common side effects, like sedation, nausea, headache, and dry mouth. Use this drug per your physician's recommendation to avoid its unwanted side effects.
H1 receptor antihistamines such as cetirizine, fexofenadine, and desloratadine are among the most commonly prescribed medications for the treatment of allergies and have been shown to stimulate appetite and weight gain as side effects of treatment (6).
Atarax (hydroxyzine hydrochloride) and Allegra (fexofenadine hydrochloride) are types of antihistamines used to treat itching caused by allergies. Atarax is also used for symptomatic relief of anxiety and tension associated with psychoneurosis and as an adjunct in organic disease states in which anxiety is manifested.
It's a common over-the-counter (OTC) antihistamine that's often used to manage allergies. It also has a sedative effect, which means it can make you sleepy. Because of this, some people use it for the short-term treatment of anxiety symptoms.
In the brain, histamine acts as a neurotransmitter which can affect the levels of mood altering neurotransmitters such as GABA, dopamine and serotonin; causing the increased expression of anxious and depressive feelings.
