How Long Does It Take Allegra to Work For Allergies?

What is Allegra?

Allegra is an over-the-counter antihistamine medication used to relieve symptoms of seasonal allergies such as sneezing, watery eyes, and runny nose. The active ingredient in Allegra is fexofenadine. By blocking histamine receptors in the body, it helps reduce allergic reactions.

Allegra comes in three formulations for relieving allergy issues:

• Allegra Allergy tablets
• Allegra Allergy liquid-filled capsules
• Children’s Allegra Allergy syrup

Allegra is considered a second-generation, non-drowsy antihistamine. This means it is less likely to cause side effects like sleepiness compared to older allergy medications.

Who Can Take Allegra?

Allegra can be used for allergy relief in adults and children as young as 2 years old. Pregnant women should consult a doctor before usage. People with liver or kidney disease may require adjusted dosing.

How Long Does it Take for Allegra to Start Working?

So how long after you pop an Allegra tablet or swallow some syrup can you expect allergy relief?

Most sources state that Allegra starts working within just 1-3 hours. The effects continue providing symptom relief for a full 24 hours per dose.

Allegra Dosage Timing

Because it kicks in quickly but works for 24 hours, the best time to take Allegra is once per day. This allows you to cover a whole day's worth of allergy relief through a single dose.

Try your best to take it at the same time every day. Setting a daily reminder on your phone may help if you have trouble remembering your medication schedule.

Getting Faster Relief

If you're impatient, you can help Allegra kick in more quickly to ease your allergy misery faster using these handy tips:

• Take on an empty stomach - avoid food for 30 minutes before and after dosing
• Wash down with plenty of water - aids absorption into bloodstream
• Get active - take a walk outside to circulate medication through your system

Factors that Influence How Long Allegra Lasts

For most users, a single Allegra dose works effectively against allergy symptoms for the full 24 hours it is designed to provide relief for.

However, there some variables that cause it to wear off sooner or later for certain individuals:

Severity of Allergies

People with moderate seasonal allergies may get longer lasting relief compared to those battling more chronic or severe allergic reactions after taking Allegra. Adjusting prescription strength might help in more persistent cases.

Consistency of Daily Doses

Taking Allegra erratically instead of at the same time every day can impact performance duration. Sticking closely to a consistent timing routine boosts dependability of 24 hours of coverage per dose.

Medication Interactions

Certain drugs are known to interact with antihistamines like Allegra, making effects wear off faster. This includes antacids, antibiotics, antifungals, and more. Speak to your pharmacist about potential issues with medicines you currently take.

Food Effects

Consuming Allegra alongside a meal, especially one high in fat, can slow down absorption and reduce time span of effectiveness. Have it on an empty tummy instead.

Typical Allegra Users Report

While clinical studies support Allegra working within 1-3 hours with 24 hours of relief, what do real-life users have to say?

Monitoring discussion boards and reviews shows typical comments like:

• "My eyes were way less itchy about two hours after my first Allegra."
• "I think it only took around 45 mins and my stuffy nose was clearing up!"
• "Always lasts all day for me, maybe around 20 hours if I'm outside a lot."
• "Doesn't work as fast as Zyrtec but keeps me allergy free for a full day with no problems."

Most people report noticeable symptom relief within that initial 1-3 hour window, with effects lasting a reliable 24 hours.

Why Doesn't Allegra Work Immediately?

While Allegra starts fighting allergies quickly, it cannot provide instant relief. This is because:

1. It takes time for the medication to dissolve and absorb into your bloodstream through the stomach
2. It must travel in the blood to target areas with histamine receptors
3. Blocking these receptors prevents more histamine release
4. Your own already-released histamine then gradually breaks down

This multi-step process prevents Allegra from working right away. Have patience and expect relief within a couple short hours.

Maximizing Allegra Effectiveness

To give Allegra the best chances of fighting your allergies optimally, keep this usage advice in mind:

Carefully Follow All Instructions

Closely adhere to the dosage guidelines and usage directions. Never take more than one dose in a 24 hour period unless explicitly advised by your doctor.

Be Consistent with Daily Dosing Time

Take Allegra at the very same time every single day without wavering more than an hour forwards or backwards. Consistency boosts dependability.

Avoid Known Interfering Substances

Stay far away from beverages, foods, and medications proven to hamper Allegra absorption and performance duration. This includes grapefruit, antacids, blood thinners, etc.

Track and Compare Your Improvements

Write down allergy levels before starting Allegra and monitor daily changes while medicating. Logging symptoms and relief helps assess if it’s working optimally for you or requires adjustments.

Switching to a Stronger Antihistamine

For most allergy sufferers, OTC Allegra provides sufficient relief. But for some, a prescription-strength medication may prove more effective if:

• Allegra isn’t controlling symptoms fully after consistent usage
• Relief lasts less than 24 hours and requires multiple daily doses
• Side effects like drowsiness or headaches occur

See your doctor to explore whether switching to a prescription antihistamine could better and more conveniently combat your allergy woes if needed.

Consider Adding a Nasal Spray as Well

While Allegra blocks histamine internally through the bloodstream, adding an OTC nasal antihistamine spray to your routine provides exterior allergy relief right where you need it - your nose!

Used along with oral Allegra capsules or tablets, a spray like fluticasone or azelastine hydrochloride can help open stuffed nasal passages and allow you to breathe easier.

Employing both interior and exterior allergy treatments often provides the most complete long-lasting relief possible.

Know When to See a Doctor

For seasonal allergy relief, Allegra often does the trick without needing medical intervention. However if you experience:

• Hives, swelling, or trouble breathing
• No symptom improvement after 1 week of daily Allegra use
• The need to take it more frequently than once per 24 hour period

Consult a physician instead to discuss stronger prescription antihistamine options or rule out other illnesses causing your issues.

Give It Time, But Make a Change If Needed

When trying a new allergy medication like Allegra, it's smart to give it adequate time before deciding if it will effectively work for you or not.

However, if taking it properly for 1-2 weeks still shows no relief, go ahead and explore alternatives like different OTC antihistamines or prescription types.

Finding the best long-term allergy treatment for your personal reaction sensitivities takes some patience through trial and error. Stick with what reliably works!
