How to Determine the Severity of Urticaria?

Before diving into treatment, it’s essential to assess the severity of your urticaria:

  • Mild Urticaria: Less than 20 hives in 24 hours that are mildly itchy but not disruptive, allowing you to continue your daily activities.
  • Moderate Urticaria: 20-50 hives in 24 hours, moderately itchy and troublesome, making daily activities more difficult but still manageable.
  • Severe Urticaria: More than 50 hives in 24 hours, severely itchy and interfering with daily life.

In addition to medication, it’s crucial to identify and eliminate triggers, as discussed in this video:

 

Which anti-allergic to take?

For mild cases of urticaria, you can try non-sedative anti-histaminics like fexofenadine. However, if this has not shown response you can consider shifting to Loratidine. It is avaible easily at Pharmacy or online under following brand names globally:

How to take?

  • Dosage:
    • For adults and children 6 years and older: The recommended dose is 10 mg once daily.
    • For children aged 2 to 5 years: The recommended dose is 5 mg once daily (either as a liquid or dissolvable tablet).
    • For children under 2 years: Consult a doctor for the appropriate dose.
  • Take with Water: Always take Allegra with plain water. Avoid fruit juices like grapefruit, orange, or apple juice, as they can reduce the absorption and effectiveness of the medication.
  • With or Without Food: Allegra can be taken with or without food, but consistency in the timing (morning or night) can help maintain even levels in your system.

How to Take Anti-Allergic Medication for Urticaria?

For best results, antihistamines should be taken daily for at least 10 days before evaluating their effectiveness. The treatment duration depends on how long your urticaria lasts:

  • Acute Urticaria lasting less than 6 weeks: Take anti-allergic for 10 days. If your symptoms completely disappear, you can stop after 10 days. However, if hives reappear or mild symptoms persist, follow the tapering schedule below.
    • Day 1 – Day 10: Take daily.
    • Day 11 – Day 20: Take it every other day.
    • Day 21 – Day 30: Take it every third day.
    • Day 31: Stop and monitor for recurrence. If hives return, consult your doctor immediately.

 

  • Chronic Urticaria (lasting more than 6 weeks): You should consult your doctor if urticaria persists for more than 6 weeks to rule out underlying causes and determine the appropriate long-term treatment plan. Given below is general guide but your doctor might decide shorter or longer tappering based on severity of disease.
    • Day 1 – Day 10: Take daily.
    • Day 11 – Day 20: Take it every other day.
    • Day 21 – Day 30: Take it every third day.
    • Day 31 – Day 40: Take it every fourth day.
    • Day 41 – Day 50: Take it every fifth day.
    • Day 51 – Day 60: Take it every sixth day.
    • Day 61: Stop and observe for recurrence. If hives return, restart with every fifth day dosing and follow a longer tapering schedule.

 

What to Do If Urticaria Reoccurs After Increasing the Gap?

You should consult your doctor if urticaria relapses to discuss appropriate long-term treatment plan.

For some patients, hives may return if antihistamines are not taken regularly. The interval between doses can vary for each individual. In some cases, hives may reappear if you miss even one dose. If this happens, take anti-allergics daily without a gap. For others, the gap may be every 1, 2, 3, 4, 5, or 7 days. Continue taking the medication at that interval for at least 3 months before trying to extend the gap by one more day. If the hives reappear, return to the previous interval. The goal is to prevent any hives while on medication.

 

FDA INFORMATION FOR LORATIDINE

Precautions

Pregnant or breastfeeding: Before taking loratadine, consult your healthcare provider if you have liver or kidney issues, or if you are pregnant or breastfeeding.

Alcohol: Limit or avoid alcohol while taking loratadine, as it may increase the risk of side effects.

Kidney Disease: Loratadine is primarily excreted by the kidneys, so if you have kidney impairment, the medication may build up in your system and increase the risk of side effects. If you have kidney disease, your doctor may recommend a lower dose or an adjustment in the frequency of doses (e.g., every other day instead of daily). Always consult your doctor before taking loratadine if you have any form of kidney dysfunction.

Liver Disease: Loratadine is metabolized by the liver, and liver disease can impair this process, causing higher drug levels in your blood, which may lead to side effects.  If you have liver disease, your doctor may recommend starting at a lower dose or adjusting the dosage schedule (e.g., every other day). It’s important to discuss your liver condition with your healthcare provider to ensure safe use.

Drowsiness: Although loratadine is considered a non-drowsy antihistamine, drowsiness can still occur in some individuals, particularly when combined with other medications or alcohol. Here are some key precautions:

  1. Assess Your Reaction First: After taking loratadine, observe how your body reacts before engaging in tasks that require full alertness, such as driving or operating heavy machinery.
  2. Avoid Alcohol and Sedatives: Consuming alcohol or sedative medications (such as sleeping pills or muscle relaxants) can increase the risk of drowsiness while on loratadine.
  3. Be Cautious with Higher Doses: In rare cases, taking higher-than-recommended doses of loratadine may cause drowsiness. Stick to the prescribed dose and do not exceed it without consulting your doctor.
  4. Drowsiness in Sensitive Individuals: Certain individuals may be more sensitive to antihistamines, even those labeled as non-drowsy. If you experience drowsiness, avoid tasks that require mental alertness until the effects wear off.

Side Effects

Common side effects may include:

  • Headache
  • Drowsiness (though less sedating than some other antihistamines)
  • Dry mouth
  • Fatigue

Serious side effects are rare but may include:

  • Fast or irregular heartbeat
  • Severe allergic reactions (rash, itching, swelling, difficulty breathing)

If you experience any serious side effects, seek medical attention immediately.

Contraindications

  • Known Allergies: Do not take loratadine if you are allergic to loratadine or any of its ingredients.
  • Age Restrictions: Consult a doctor before giving loratadine to children under 2 years of age.

Drug Interactions

  • CYP3A4 Inhibitors: Certain medications that inhibit the CYP3A4 enzyme (e.g., ketoconazole, erythromycin) may increase the levels of loratadine in the blood. Consult your healthcare provider about potential interactions.
  • Other Antihistamines: Avoid taking loratadine in combination with other antihistamines, as this can increase the risk of side effects.

Always consult your healthcare provider or pharmacist if you have questions about taking loratadine or its interactions with other medications.

Final Thoughts

Proper use of antihistamines like Loratidine can make a significant difference in controlling urticaria. Consistency is key, and tapering off the medication should be done carefully to avoid recurrence. Always consult with a healthcare provider for personalized advice and follow the recommended tapering schedule based on your symptoms. By adhering to these guidelines, you can manage urticaria effectively and improve your quality of life.
