Allegra-M 120 mg/10 mg Tablet contains fexofenadine (120 mg), an antihistamine that relieves allergy symptoms, and montelukast (10 mg), a leukotriene receptor antagonist that reduces inflammation and helps control asthma and allergic rhinitis.

I highly recommend consulting a dermatologist or an allergist for your symptoms. Regarding Allegra (fexofenadine), 180 mg twice daily is a higher-than-standard dose. While hair loss is an extremely rare side effect of fexofenadine, the underlying chronic rash or bodily stress itself can trigger hair shedding. You can safely stop taking it, but stopping abruptly may cause your itchy rash to flare up. It is best to consult your doctor to safely adjust your dose and find the right relief.

Since Allegra (fexofenadine) helped before, you can discuss restarting it with a healthcare provider. In the meantime, please avoid licking or picking your lip, and apply a plain, fragrance-free ointment like petroleum jelly to soothe and protect the skin barrier. Because of the oozing, I highly recommend having a doctor examine it, as you may need a prescription topical treatment to help it fully heal.

Since you manage diabetes and high blood pressure, these symptoms could be related to circulation issues or dry skin. For immediate, safe relief, apply cool, damp compresses to your legs and use a gentle, fragrance-free moisturizing cream. Avoid hot baths, which worsen itching. Because of your health conditions, please have your doctor evaluate your legs promptly to check your circulation and blood sugar. They will help find the safe, targeted treatment you need.

Since topical treatments like ketoconazole and Candid powder haven't worked, and the infection has spread, you likely require a prescription oral antifungal medication. The skin darkening you noticed is post-inflammatory hyperpigmentation, which is very common and will gradually fade once the infection is fully cleared. Please stop using the Ayurvedic remedies, keep the area clean and dry, wear loose cotton clothing, and consult a doctor or dermatologist for a targeted prescription plan to finally resolve this.

While a lack of sleep can certainly worsen hives by increasing stress and inflammation in your body, it is rarely the sole cause. Chronic hives, which you are currently managing with Allegra (fexofenadine), can also be triggered by emotional stress, physical factors like heat or pressure, certain foods, or underlying immune responses. Since they occur daily, keeping a symptom diary to track your sleep, diet, and stress can be very helpful. I highly recommend consulting an allergist or dermatologist to help identify any other underlying triggers.
