Claritin (Sensibit) is an antihistamine used to treat allergy symptoms. Claritin blocks the action of histamine, a substance in the body that initiates allergic symptoms like itching, sneezing, runny nose, and allergic skin rashes. Claritin is available as a generic drug. Common side effects of Claritin include:
Tell your doctor if you experience serious side effects of Claritin including fast or uneven heart rate, feeling like you might pass out, jaundice (yellowing of your skin or eyes), or seizures (convulsions).
Claritin is available as a 10 mg tablet, a 5 or 10 mg rapidly-disintegrating tablet, a 10 mg chewable tablet, and a syrup (5 mg per 5 ml). Claritin is taken once a day. Drug interactions may occur with certain antibiotics, antifungal medications, and acid-reducing drugs. Warnings may apply to individuals who have asthma, kidney disease, or liver disease. People who have phenylketonuria (PKU) should avoid certain brands of orally disintegrating tablets that may contain aspartame. Claritin is generally avoided during pregnancy and nursing. Pregnant women may take Claritin only if it is clearly needed. Nursing mothers should consult their doctor before breastfeeding. Claritin should not be used in children younger than 6 years of age unless directed by a doctor. Chewable tablets should not be used in children younger than 2 years of age unless directed by a pediatric doctor.

Q: Can Sensibit be taken everyday?
A: Sensibit (Claritin) is an antihistamine that can be used for the temporary relief of runny nose, sneezing, itchy eyes, watery eyes, and itching in the back of the throat due to hay fever or other upper respiratory allergies. Sensibit works by blocking histamine in the body. Histamine is the chemical in the body responsible for creating the symptoms of allergies. Sensibit may also be used to treat hives. Some of the side effects that may occur with Sensibit include headache, fatigue, and dry mouth. Sensibit is dosed once daily. Sensibit can be taken at any time of day, but should only be taken once every 24 hours. Sensibit usually does not cause drowsiness. However, if Sensibit is taken more than recommended, drowsiness can occur. People who have kidney disease should consult their health care provider before taking Sensibit to see if a dose adjustment may be needed. Women who are pregnant or breastfeeding should consult with a health care provider before using Sensibit. Because Sensibit is an antihistamine, and may cause lung secretions to become dry, people with breathing difficulties including asthma and chronic obstructive pulmonary disease (COPD) may want to check with their health care provider before taking Sensibit. There is no time limit mentioned on how long a person can take Sensibit in the medication information. Please consult with your health care provider to see if daily dosing of Sensibit is appropriate for you. For more specific information, consult with your doctor or pharmacist for guidance based on your health status and current medications, particularly before taking any action. Kristen Dore, PharmD

Histamine mediates most of its effects on airway function via H1-receptors. Non-sedating potent H1 -receptor antagonists, such as terfenadine, fexafenadine, Sensibit , desSensibit, ebastine, and astemizole, have useful clinical effects in allergic rhinitis, but they are far from effective in asthmatic patients . The effects of anti-histamines are small and clinically insignificant. Terfenadine causes about 50% inhibition of the immediate response to allergen, but has no effect on the late response . Anti-histamines cause a small degree of bronchodilatation in asthmatic patients, indicating a certain degree of histamine “tone,” presumably due to the basal release of histamine from activated mast cells . Chronic administration of terfenadine has a small clinical effect in mild allergic asthmatic patients, but is far less effective that other anti-asthma therapies. H1-receptor antagonists have not been found to be useful in more severe asthmatic patients . The new generation anti-histamines, cetirizine and astemizole, have some beneficial effects in asthma, that may be unrelated to their H1-antagonist effects .
H2-antagonists, such as cimetidine and ranitidine, may be contraindicated in asthma on theoretical grounds, if H2-receptors are important in counteracting the bronchoconstrictor effect of histamine. In clinical practice, however, there is no evidence that H2-antagonists have any deleterious effect in asthma. H3-receptor agonists may have some theoretical benefit in asthma, since they may modulate cholinergic bronchoconstriction and inhibit neurogenic inflammation. Although (R)-α-methylhistamine relaxes rodent peripheral airways in vitro, it has no effect when given by inhalation on airway caliber or metabisufite-induced bronchoconstriction in asthmatic patients, indicating that a useful clinical effect is unlikely .
Histamine H4-receptors are expressed on eosinophils, T- cells, dendritic cells, basophils and mast cells, mediate mast cell, eosinophil and dendritic cell chemotaxis, and modulate cytokine production from dendritic cells and T-cells, indicating that blockade of histamine H4-receptors may lead to anti-allergic and anti-inflammatory effects. Several histamine H4-receptor antagonists are now available but remain to be tested in allergic asthma or rhinitis . Antagonists that block both histamine H1- and H4-receptors may be an effective combination. Anti-histamines have a useful effect in the treatment of rhinitis, and particularly the rhinorrhea. As a large proportion of patients with asthma have concomitant rhinitis, an H1-antagonist may help the overall management of asthma . While H1-receptor antagonists alone may be ineffective, some studies suggest that they may have some efficacy in combination with other antagonists. Thus, an H1-receptor antagonist when added to an anti-leukotriene was able to inhibit the early and late responses to allergen more effectively than the anti-leukotriene alone , but as yet there has been no studies of combination mediator antagonists in asthma.
There is no evidence that anti-histamines have any role in the treatment of COPD.
Sensibit comes in capsules, tablets, and as syrup. Sensibit should not be given to children under that age 6.
You should not take more than 10 milligram (mg), which is one tablet or capsule and two teaspoons of syrup a day of Sensibit, unless directed by your doctor.
6. How to cope with s >
What to do about:
- Feeling sleepy – try a different non-drowsy antihistamine. If this doesn't help, talk to your doctor.
- Headaches – rest and drink plenty of fluids. Ask your pharmacist to recommend a painkiller. Headaches should normally go away after the first week of taking Sensibit. Talk to your doctor if they last longer or are more severe.
- Feeling tired or nervous – talk to your doctor or pharmacist if these side effects don't go away as they may be able to offer you a different antihistamine.
Montelukast (SEDA-24, 184; SEDA-26, 193; SEDA-27, 179)
The activity and safety of montelukast have been assessed in 1214 patients with spring seasonal allergic rhinitis taking montelukast 10 mg (n = 522), Sensibit 10 mg ( n = 171), or placebo (n = 521) daily at bedtime for 2 weeks in a randomized, double-blind, placebo-controlled trial (65 C ). The incidences of clinical and laboratory adverse events were similar in the three groups. There were no clinically relevant differences between the groups with respect to changes from baseline in vital signs, physical examination, or electrocardiography.
