Rigix Syrup is an anti-allergy oral syrup manufactured by AGP limited. It is an FDA-approved oral medication that contains cetirizine and is a non-sedating second-generation antihistamine used to treat allergy symptoms in children and adults. Rigix Syrup works by regulating the generation of allergy mediators.
Composition of Rigix Syrup
Its active ingredient is cetirizine hydrochloride (5 mg per 5 ml), which is a second-generation antihistamine and helps reduce allergy symptoms. It works by blocking histamine, which is the main cause of allergic reactions. In addition, this syrup also contains some inactive ingredients that improve its stability, taste, and overall performance:
- Purified Water: This is the liquid base that is free of contaminants and dissolves the active ingredients.
- Glycerin: Softens the texture of the syrup and extends its shelf life.
- Sorbitol: This is a natural sweetener that sweetens the syrup and is also safe for diabetics.
- Sodium Benzoate and Citric Acid: These protect the syrup from bacteria and fungi, and stearic acid helps balance the pH level.
- Artificial Fruity Flavor: This makes the syrup taste sweeter, especially for children.
All these ingredients make Rigix Syrup not only effective but also easy to use medicine, which provides relief from allergy symptoms with minimal drowsy effects.
How Does Rigix Syrup Work?
Cetrizine hydrochloride is an H1-receptor antagonist that blocks histamine. Histamine is a chemical that causes the symptoms of allergic reactions. Rigix Syrup relieves allergy symptoms by blocking the effects of histamine.
Uses Rigix Syrup
Now let’s talk about the use of Rigix Syrup, i.e. in which situations you can use this syrup. Below you will find its detailed information.
- Allergic Rhinitis
- Urticaria
- Skin Allergies
- Seasonal Allergies
- Food Allergies
Allergic Rhinitis
Rigix Syrup is very effective in treating allergic rhinitis. It is recommended for people who suffer from symptoms like sneezing, runny nose, stuffy nose, and itchy eyes. Allergic rhinitis is caused by pollen, dust, or another allergen, and Rigix Syrup reduces these symptoms by blocking the effects of histamine. It is also especially effective for seasonal allergies.
Urticaria
Urticaria, which appears as itchy and red raised bumps on the skin, is a common allergic reaction. Rigix Syrup treats urticaria by reducing itching and swelling. It is very helpful for people who suffer from chronic urticaria (long-term hives).
Skin Allergies
Rigix Syrup is also used to treat skin allergies such as eczema and dermatitis. It reduces skin irritation and soothes the patient by reducing itching and redness. Skin allergies are often caused by a chemical, food, or environmental allergen, and Rigix Syrup helps neutralize their effects.
Seasonal Allergies
Seasonal allergies are often caused by pollen, dust mites, and pet dander. Rigix Syrup helps prevent the reaction to these allergens and effectively treats symptoms like sneezing, runny nose, and itchy eyes. It is very useful during seasonal changes for those who suffer from frequent allergies.
Food Allergies
Rigix Syrup is also used to treat mild food allergies. If a food allergen (such as a nut or seafood) is causing mild itching or swelling, Rigix Syrup can control symptoms. But for severe food allergies (such as anaphylaxis), Rigix Syrup alone is not enough, and immediate medical attention is necessary.

Missed Dose

Precautions and Warnings
If you are using Rigix Syrup or any other medicine, I suggest you to know the precautions and warnings of any medicine before using it. This can help you avoid possible damage to the medicine.
For Children
Rigix Syrup should not be used by children under 2 years of age without a doctor’s approval. Young children have different immune systems and metabolisms than adults, and the dosage and effect of medicine may be different for them. Overdose or misuse can cause harm, so a doctor’s guidance is essential.
Pregnancy and Breastfeeding
Pregnant and lactating mothers should consult a doctor before taking Rigix Syrup. The effects of cetrizine hydrochloride on a pregnant or breastfeeding woman have not been fully researched, but precautions should be taken. The doctor will decide according to the patient’s condition whether it is safe to take Rigix Syrup or not.
Kidney and Liver Problems
People with kidney or liver problems should take Rigix Syrup only as directed by a doctor. The kidneys and liver are the body’s means of metabolism and elimination of drugs. If their function is disrupted, the drug can accumulate in the body, which can cause toxic effects. The doctor may adjust the dose or prescribe an alternative medicine.
Driving and Using Machinery
Rigix Syrup does not usually cause drowsiness, but some people may feel drowsy or tired. If you feel drowsy or lose concentration after taking the medicine, avoid driving, operating heavy machinery, or doing work that requires attention. These precautions reduce the risk of accidents.
Drug Interactions
Avoid taking Rigix Syrup with statins (such as sleeping pills) or alcohol, as this combination may cause excessive sleepiness and loss of concentration.
If you are taking any other medicines, be sure to inform the doctor or pharmacist so that they can evaluate possible drug reactions. These precautions will help protect you from the side effects of the medicine.
