The search for 'relekast cold' frequently leads to information about other brand names. The two most common and relevant are Relikast, which is more for allergies, and Relax Cold, which is specifically for cold symptoms. Knowing the difference is crucial, as their active ingredients and intended uses vary significantly.
Relikast Cold (Relikast LC) for Allergies and Asthma
Relikast LC is a common brand name that is likely what many people mean when they type 'relekast cold'. It is primarily an anti-allergy and asthma medication, not a traditional cure for the common cold virus itself.
How Relikast LC works
Relikast LC contains a powerful combination of two active ingredients that work synergistically to alleviate allergic reactions and related conditions:
- Levocetirizine: This is an antihistamine that blocks the action of histamine, a natural substance the body produces during an allergic reaction. By blocking histamine, it helps to relieve symptoms like sneezing, a runny nose, and watery eyes.
- Montelukast: This is a leukotriene receptor antagonist. It works by blocking another chemical messenger called leukotriene, which reduces inflammation and swelling in the airways and nasal passages. This action helps to improve breathing and other respiratory symptoms associated with asthma.
Common uses for Relikast LC: It is used to manage a range of allergic conditions, including allergic rhinitis (hay fever), chronic hives (urticaria), and to prevent asthma attacks. The antihistamine provides quick relief for immediate symptoms, while the montelukast offers longer-term anti-inflammatory benefits for the respiratory system.
Relax Cold for Common Cold Symptoms
Another similar-sounding medication is Relax Cold, which is explicitly formulated for common cold symptoms. Unlike the allergy-focused Relikast, this is a multi-ingredient product designed to combat the various aches, pains, and congestion that accompany a cold.
How Relax Cold works
Relax Cold typically contains a combination of five active ingredients, each targeting a different cold symptom:
- Caffeine: A stimulant that helps combat the fatigue associated with a cold.
- Cetirizine: A different type of antihistamine that provides relief from symptoms like a runny nose and watery eyes.
- Nimesulide and Paracetamol: These are analgesics (pain relievers) and antipyretics (fever reducers) that help with body aches, headache, and fever.
- Phenylephrine: A nasal decongestant that narrows the blood vessels in the nasal passages, helping to relieve stuffiness and congestion.
Common uses for Relax Cold: It is used to provide temporary relief from the symptoms of the common cold, such as body ache, headache, fever, runny nose, and nasal congestion.

| Key Active Ingredients | Levocetirizine (antihistamine), Montelukast (leukotriene antagonist). | Caffeine, Cetirizine, Nimesulide, Paracetamol, Phenylephrine. |
| Main Mechanism | Blocks inflammatory chemicals (histamine and leukotriene) associated with allergies. | Combination therapy addressing pain, fever, fatigue, and congestion. |
| Common Side Effects | Fatigue, headache, dry mouth, sleepiness. | Drowsiness, dizziness, liver toxicity (with prolonged use). |
| Consideration | Not intended for viral cold treatment. Can cause drowsiness. | Broad relief for cold symptoms. Avoid alcohol and check for caffeine content. |
Potential risks and precautions
Because the names are so similar, there is a risk of taking the wrong medication for your symptoms. This can lead to ineffective treatment or unwanted side effects. For example, taking Relikast LC for a simple cold virus might provide limited relief for congestion, but it won't address the fever or aches effectively. Conversely, using Relax Cold for an asthma-related issue would not be appropriate. Both medications can cause drowsiness, so it is important to understand the specific ingredients and how they might affect you before driving or operating machinery.
Conclusion
To answer the question, 'what is relekast cold used for?', it is important to recognize that this is a misspelling of other brand names, specifically Relikast (for allergies and asthma) and Relax Cold (for cold symptoms). These medications contain very different active ingredients and are designed to treat distinct conditions. Always verify the correct brand name with a healthcare professional or pharmacist to ensure you are taking the right medication for your specific needs, and never take medication based on a guessed or misspelled name. Consulting the package insert or a qualified medical professional is the safest way to proceed with any medication.
