Dellegra Combination Tablets (antiallergic drug)


Dellegra Combination Tablets

Dellegra Combination Tablets is a drug developed by the Sanofi Group.

Dellegra Combination Tablets for rhinitis and nasal congestion are now available.

Originally a prescription drug, they are expected to have good effects.


Features of Dellegra Combination Tablets

This section describes the effects of Dellegra Combination Tablets, an allergic rhinitis medication, and its side effects, including drowsiness and insomnia. While Dellegra is particularly effective in treating symptoms of nasal congestion, it is a drug that requires care in how it is taken. The key points on how to take it are also introduced in detail.


Dellegra is an effective medicine for allergic rhinitis.

Allergic rhinitis is caused by allergic reactions to various substances such as pollen, dust mites, and house dust. Runny or stuffy nose from hay fever is one of the symptoms of allergic rhinitis.


Antihistamines are mainly prescribed for allergic rhinitis to reduce allergic symptoms such as itching and runny nose, but antihistamines have the disadvantage that they are less effective for nasal congestion.

Dellegra is a prescription drug that contains both an antihistamine to treat allergy symptoms and an ingredient to improve nasal congestion.


As a result, it is highly effective in improving nasal congestion that is difficult to treat with antihistamines.

Dellegra is recommended for those who experience particularly strong nasal congestion or whose nasal congestion does not improve with anti-allergy medication alone.



Dellegra contains two ingredients

Dellegra is a combination of an antihistamine called "fexofenadine" and a nasal congestion-relieving ingredient called "pseudoephedrine hydrochloride.

These two different ingredients work together to treat nasal congestion that is difficult to treat with antihistamines alone.


Fexofenadine, the same ingredient as Allegra

Fexofenadine is a second-generation antihistamine that suppresses the action of histamine, which causes allergies, and relieves symptoms.


It is also the main ingredient in Allegra, a hay fever medication.

Pseudoephedrine hydrochloride, an ingredient that improves swelling of the nasal mucosa

Pseudoephedrine hydrochloride" has the effect of improving swelling of nasal mucous membranes by constricting blood vessels.


This action improves nasal congestion caused by swelling of the nasal mucosa.


Dellegra dosage points

Take twice a day

It is used twice a day, in the morning and evening, on an empty stomach. Usually adults and children over 12 years of age take 2 tablets at a time.


It is important to take on an empty stomach!

Dellegra is used on an empty stomach. An empty stomach is recommended 1 hour before or 2 hours after a meal.


Fasting is recommended because it has been reported that the absorption of the drug is reduced when used after a meal, resulting in a 60-70% decrease in maximum blood concentration.


The most effective times for use are upon awakening and in the evening on an empty stomach. Nasal congestion is generally felt more strongly in the morning when one wakes up and at night. Taking it upon awakening or on an empty stomach in the evening can have a quicker effect on nasal congestion, making it more effective for congestion that is more intense in the morning or at night.


Avoid prolonged use

Dellegra should be used only for a minimal period of time when nasal congestion symptoms are severe, and switch to an antihistamine-only medication as soon as the congestion improves.

Side effects of Dellegra, including drowsiness and insomnia

The most common side effects are headache, rash, fatigue, and dry mouth. According to the package insert, the most frequent occurrence is headache, but the probability of headache is slight, about 0.4%.


Do they make you sleepy?

Many people may have the impression that hay fever medication makes them sleepy when they take it.


Dellegra is one of the hay fever medications that is relatively less likely to cause drowsiness.


Many drugs for allergic rhinitis contain antihistamines. Histamine is a substance that causes allergic symptoms, but it is also involved in arousal of consciousness, so suppressing its action can lead to drowsiness and difficulty concentrating.


Fexofenadine, an antihistamine contained in Dellegra, has a milder effect and is less likely to cause drowsiness.


Insomnia Side Effects May Occur

Insomnia is also reported as a side effect of Dellegra, although its frequency is unknown.

This may be due to the fact that pseudoephedrine hydrochloride, an ingredient of Dellegra, stimulates the sympathetic nervous system.


If you experience symptoms of insomnia in spite of the fact that there is no problem with the timing of taking the drug, consult your doctor.


People who should be cautious about using Dellegra

Pseudoephedrine hydrochloride constricts blood vessels. You should not use Dellegra if you have a medical condition that may be aggravated by constricting blood vessels, such as the following
