Allevia 120mg is an over-the-counter non-drowsy, second-generation antihistamine. Each film-coated tablet contains 120mg of Fexofenadine Hydrochloride. A standard small pack contains 7 tablets (providing a full 7-day daily treatment course).
Taken daily by mouth, adults and adolescents aged 12 and over use it to treat and relieve seasonal allergic rhinitis (hay fever) symptoms, such as sneezing, itchy or runny nose, itchy and watery eyes, and nasal congestion.
When you come into contact with environmental allergens like grass or tree pollen, your body's immune system releases a chemical called histamine. Histamine binds to specific $H_1$ receptors in your nose, eyes, and throat, triggering inflammation, fluid production, and sneezing. Allevia targets this allergic chain reaction:
Blocks $H_1$ Histamine Receptors: Fexofenadine selectively attaches to peripheral $H_1$ receptors throughout your body, blocking natural histamine from binding and halting the allergic signal before it starts.
Non-Drowsy Formula: Unlike older, first-generation antihistamines (like Chlorpheniramine/Piriton), Fexofenadine does not easily cross the blood-brain barrier into your central nervous system. This means it delivers powerful allergy relief without making you feel sleepy, groggy, or sluggish.
Rapid and Continuous 24-Hour Relief: Starts working within 1 hour of swallowing and provides a steady, continuous 24-hour shield against hay fever symptoms with just a single daily tablet.
🚨 Critical Dosing Warning: Do NOT take Allevia tablets with fruit juices (such as grapefruit, orange, or apple juice).
Fruit juices contain natural compounds that block an intestinal transporter protein (OATP1A2) required for your body to absorb Fexofenadine into your bloodstream.
Taking this medicine with fruit juice can reduce its absorption by almost 50%, making the tablet far less effective.
Always swallow your tablet whole with plain water.
Indigestion Remedies (Antacids): Do not take indigestion remedies containing aluminum or magnesium hydroxide at the same time as Allevia. These antacids bind to Fexofenadine in your stomach, lowering its effectiveness. Leave a gap of at least 2 hours between taking an antacid and taking your Allevia tablet.
Kidney and Liver Precautions: If you have reduced kidney function, severe kidney disease, or liver problems, consult your doctor or pharmacist before use, as your body may require a lower dose or adjusted schedule.
Elderly and Heart Conditions: Individuals with a history of cardiovascular disease should use antihistamines cautiously, as a very small subset of patients may experience palpitations or a fast heartbeat.
Pregnancy and Breastfeeding: Fexofenadine is standardly not recommended during pregnancy or breastfeeding unless explicitly advised by a physician after weighing the risks and benefits.
The Normal Amount: The standard adult dose is strictly 1 tablet (120mg) once daily.
Age Limit: Suitable for adults and children aged 12 years and older. (Not recommended for children under 12; lower strengths or pediatric liquid formulations are used for younger children).
Timing & Method: Take your single tablet with a full glass of plain water before a meal.
Swallow Whole: Swallow the tablet completely whole. Do not chew, crush, or break it.
1.Take 1 tablet whole with plain water:Plain Water Only.
Swallow 1 tablet whole before a meal. Never take it with fruit juices (grapefruit, orange, or apple) to avoid blocking absorption.
2.Keep 2 hours away from indigestion remedies:Space Antacids.
If you take heartburn or antacid medicines containing aluminum or magnesium, ensure a 2-hour gap before or after your Allevia dose.
3.Maintain a consistent daily schedule:24-Hour Shield.
Take your tablet at the same hour every day to maintain smooth, 24-hour protection throughout the pollen season.
Allevia is exceptionally well-tolerated and designed to minimize central nervous system effects, but minor bodily updates can occasionally occur:
Mild headache or occasional feeling of lightheadedness.
Mild drowsiness or fatigue (though far less common than with older antihistamines).
Mild nausea, dry mouth, or minor gastrointestinal discomfort.
Note: If you experience severe dizziness, a racing heartbeat/palpitations, or signs of an immediate severe allergic reaction (such as widespread hives, facial swelling, or difficulty breathing), stop taking the tablets and seek medical attention immediately.
Can I drive or operate machinery while taking Allevia 120mg?
Yes, for the vast majority of people. Fexofenadine is clinically categorized as a non-drowsy antihistamine and is unlikely to affect your concentration or driving ability. However, to be completely safe, check how your body responds to the first dose before driving or operating heavy machinery.
What should I do if I accidentally forget to take my daily tablet?
Take your missed tablet as soon as you remember that day, as long as it is taken with plain water. However, if it is almost time for your next scheduled daily dose, skip the forgotten tablet completely and continue your regular once-daily schedule. Never take 2 tablets at the exact same time to compensate for a missed dose.
How should the 7-tablet pack be stored safely in warm climates?
Keep your tablets sealed flat inside their original factory foil blister strip to protect them from tropical humidity and ambient moisture. Store in a cool, dry room strictly below 25°C or 30°C, completely away from hot kitchen counters, damp bathrooms, or direct window sunlight, and keep out of the reach of children.
To ensure you are purchasing 100% genuine, original factory-authenticated Allevia 120mg Tablets (7s Pack)—handled under temperature-regulated safety to prevent active antihistamines from degrading in tropical heat—you can place your order directly online through Sanlive Pharmacy & Stores. We provide verified clinical sourcing, secure transaction processing, and fast, protected delivery straight to your home or office anywhere in Nigeria.
Notice: This guide is for educational and allergy tracking support only. Severe, non-responsive hay fever, severe asthma symptoms, or chronic unexplained rashes require physical evaluation by a physician or allergist. If someone accidentally swallows a massive overdose of tablets all at once, or displays signs of an immediate severe allergic shock (facial/throat swelling with immediate breathing distress), stop use completely and seek emergency clinical intervention at the nearest hospital emergency department right away.
