Loratin Fast 10 mg Tablet
Generic: Loratadine
Manufacturer: Square Formulations Ltd.
Therapeutic class: Non-sedating antihistamine (second generation)
What is Loratin Fast?
Loratin Fast 10 mg tablet is manufactured by Square Formulations Ltd.. It contains Loratadine, a second-generation non-sedating antihistamine widely used in Bangladesh to relieve allergy symptoms such as sneezing, runny nose, itchy eyes and skin rash. Because it causes far less drowsiness than older antihistamines, it is suitable for daytime use at work, school or while travelling.
Loratadine works by blocking H1 histamine receptors. When the body meets an allergen such as dust, pollen or animal dander, it releases a chemical called histamine, which triggers sneezing, itching, watery eyes and a blocked or runny nose. By stopping histamine from acting, Loratin Fast relieves these symptoms for about 24 hours, and because it does not readily enter the brain, sleepiness is uncommon.
Indications
Loratin Fast is commonly prescribed for:
- Allergic rhinitis (seasonal and year-round) — sneezing, runny or itchy nose, and itchy, watery eyes caused by dust, pollen, mould or pet dander
- Hay fever symptoms
- Chronic urticaria (long-standing hives) — relief of itching and reduction in the number and size of wheals
- Itchy allergic skin conditions such as rashes and insect-bite reactions
- Allergy symptoms accompanying the common cold, when recommended by a doctor
Your doctor may also prescribe Loratin Fast for other allergy-related conditions not listed here.
Dosage & Administration
The usual adult dose of Loratin Fast is 10 mg once daily, taken with or without food. A single daily dose generally controls symptoms for a full 24 hours.
- Adults and children over 12 years: 10 mg once daily, or as the doctor advises
- Children: the dose depends on age and body weight, and a syrup form is usually preferred — always follow the doctor's instructions
- Liver or kidney disease: the doctor may advise taking the dose every other day
Do not take more than the prescribed amount. Your doctor will decide the right dose and duration of Loratin Fast for your condition.
Side Effects
Loratin Fast is generally well tolerated and most people experience no problems. Possible side effects include:
- Headache
- Tiredness or fatigue
- Dry mouth
- Drowsiness (uncommon at the usual dose)
- Stomach upset or nausea
- Nervousness or restlessness, mainly in children
Serious reactions are rare. Seek medical help immediately if you notice swelling of the face, lips or throat, difficulty breathing, severe rash, or a fast or irregular heartbeat after taking Loratin Fast. If any side effect persists or troubles you, contact your doctor.
Precautions & Warnings
- Tell your doctor if you have liver disease or kidney disease — the dose may need adjustment
- Stop taking Loratin Fast at least 48 hours before allergy skin tests, as it can mask positive results
- Do not give to children under 2 years unless prescribed by a doctor
- Some formulations contain sugar or lactose — inform your doctor if you have diabetes or an intolerance
- Although drowsiness is uncommon, see how Loratin Fast affects you before driving or operating machinery
- Do not exceed the recommended dose — higher doses can cause sleepiness or palpitations
Drug Interactions
Tell your doctor about all medicines, supplements and herbal products you take. Medicines that may interact with Loratin Fast include:
- Ketoconazole and other azole antifungals — can raise loratadine blood levels
- Erythromycin and similar macrolide antibiotics
- Cimetidine (an acid-reducing medicine)
These combinations increase the amount of loratadine in the blood, although this is usually not clinically dangerous. Avoid taking other sedating antihistamines together with Loratin Fast, and limit alcohol, which can add to any drowsiness. Always check with your doctor or pharmacist before starting a new medicine.
Contraindications
Do not take Loratin Fast if you:
- Are allergic to loratadine, desloratadine or any other ingredient of the preparation
- Have previously had a severe reaction (rash, swelling, breathing difficulty) after taking this medicine
Use with caution, and only on a doctor's advice, in severe liver impairment, in children under 2 years, and during pregnancy or breastfeeding. If you are unsure whether Loratin Fast is suitable for you, speak to your doctor or pharmacist before taking it.
Pregnancy & Lactation
Pregnancy: Loratadine is generally regarded as one of the safer antihistamines in pregnancy, but no medicine should be taken during pregnancy without medical advice. Use Loratin Fast only if your doctor considers it necessary.
Breastfeeding: Small amounts of loratadine pass into breast milk. Because it is non-sedating and used in low doses, doctors often consider it compatible with breastfeeding, but you should still consult your doctor before use. Watch the baby for unusual sleepiness or irritability and report any concern to your doctor.
Storage Conditions
Store Loratin Fast below 30°C in a cool, dry place, protected from direct sunlight and moisture. Keep the medicine in its original pack until use.
- Keep out of the reach and sight of children
- Do not use after the expiry date printed on the pack
- Do not refrigerate syrups unless the label says so, and discard any remaining syrup within the period stated on the label after opening
Frequently Asked Questions
Does Loratin Fast make you sleepy?
Loratin Fast contains loratadine, a non-sedating antihistamine, so it causes much less drowsiness than older allergy medicines such as chlorpheniramine. Most people can take it during the day and continue working normally. A small number of people may still feel mildly sleepy, so see how it affects you before driving, and avoid alcohol, which can increase drowsiness.
How quickly does Loratin Fast start working and how long does it last?
Loratin Fast usually starts to relieve allergy symptoms within 1 to 3 hours of taking it, reaches its full effect in about 8 to 12 hours, and keeps working for around 24 hours. This is why a single daily dose is enough for most people. Taking it at the same time each day helps maintain steady relief.
Can I take Loratin Fast every day for a long time?
Yes — for long-lasting conditions such as chronic urticaria or persistent allergic rhinitis, doctors often prescribe loratadine daily for several weeks or months. It is not habit-forming. However, the right duration depends on your condition, so follow your doctor's advice and go back for review if symptoms continue despite regular use of Loratin Fast.
