If you or your child suffers from allergies, your doctor or pharmacist may recommend a medicine called DESELEX®. This medication helps manage symptoms like sneezing, runny nose, itchy eyes, and even hives. But DESELEX® comes in two forms: syrup and tablets. Which one is better for you or your child? This guide explains everything in clear, simple language to help you understand and compare both options.
What is DESELEX®?
DESELEX® is an anti-allergy medicine. Its active ingredient is desloratadine, which belongs to a group of medicines called antihistamines. These medicines help reduce allergy symptoms by blocking a natural substance in your body called histamine.
DESELEX® comes in two main forms:
- DESELEX® Syrup: Contains 2.5 mg of desloratadine in every 5 ml of syrup.
- DESELEX® Tablets: Each tablet contains 5 mg of desloratadine.

Warnings and Precautions
- Driving or using machinery: While desloratadine usually doesn’t cause drowsiness, some people may feel sleepy. If that happens, avoid driving or using machines.
- Drug interactions: Tell your doctor about all medications you are taking, especially:
- Antifungals like ketoconazole
- Antibiotics like erythromycin and azithromycin
- Antidepressants like fluoxetine
- Acid-reducing meds like cimetidine
DESELEX® In Case of Pregnancy
DESELEX® is not recommended for use during pregnancy. Although animal studies haven’t shown harmful effects, there isn’t enough information about its safety in human pregnancies. Because of this, doctors advise avoiding it during pregnancy unless the benefits clearly outweigh the risks.
Important: Always talk to your doctor before taking any medicine while pregnant — even over-the-counter ones.
Why Should DESELEX® Be Avoided During Pregnancy?
- There’s not enough research to say it’s completely safe.
- DESELEX® contains desloratadine, which can cross into the bloodstream and might reach the baby.
- Even though no harmful effects were seen in animal tests, humans might react differently.
What If You Accidentally Took DESELEX® While Pregnant?
Don’t panic. One accidental dose is unlikely to harm you or your baby. But you should still:
- Tell your doctor or midwife.
- Let them know how much you took and when.
- Follow their advice for what to do next.
Can I Take DESELEX® While Trying to Get Pregnant?
It’s best to avoid it while trying to conceive, unless your doctor says it’s okay.
Are There Safer Alternatives for Pregnant Women With Allergies?
Yes, some allergy medicines are considered safer during pregnancy. Your doctor might recommend:

DESELEX® should also be avoided while breastfeeding. That’s because:
- Desloratadine can pass into breast milk.
- It’s not clear how it may affect your baby.
- Doctors usually advise against using it unless absolutely necessary.
If you’re breastfeeding and need allergy relief, safer options might include:
- Non-sedating antihistamines (like loratadine or cetirizine) in low doses
- Natural remedies, such as saline sprays or steam therapy
Storage Instructions
- Store below 30°C in the original container.
- Do not refrigerate or keep in a bathroom.
- Keep away from children.
- Do not use after expiry date.
- Return unused medicine to your pharmacy.
Special Notes on Ingredients

- Tablet: Contains lactose. Not suitable for people with lactose intolerance.
How Fast Does It Work?
- Many users feel symptom relief within 1 to 2 hours of taking DESELEX®.
- The effects last for a full 24 hours, making it convenient for once-a-day use.
Pharmacological Insights (Simple Explanation)
Desloratadine works by blocking histamine – the chemical in your body that causes allergy symptoms. Unlike older antihistamines, it does not usually make you sleepy.
Desloratadine starts working within 30 minutes, reaches its peak in about 3 hours, and stays active for around 27 hours. It binds to proteins in your blood and doesn’t build up too much over time.
