Frequent nose and throat infections during weather changes may be due to an allergy or low immunity. Allegra helps control allergy symptoms but may not prevent infections completely. Avoid cold exposure, maintain good hygiene, and support your immunity with a healthy lifestyle. Consult a doctor to review your condition and confirm the most suitable treatment.

Since oral itraconazole and antihistamines weren't effective, the next best step is seeing a dermatologist. They can perform a skin scraping, culture, or biopsy to check for bacterial infections, atypical yeasts, or inflammatory conditions like inverse psoriasis. For relief, they might suggest drying solutions (like aluminum acetate), topical mild steroid creams, or non-steroidal anti-inflammatory topicals.

It sounds like you are experiencing an allergic reaction, likely contact dermatitis from the hair treatment chemicals. Since you have already taken fexofenadine (Allegra), this should help reduce the itching. You can gently wash your scalp and hair with lukewarm water and a mild, fragrance-free shampoo to remove any remaining chemical residue. Applying a cool, damp compress or a mild, over-the-counter hydrocortisone cream to the affected skin can also provide relief. Please avoid scratching to prevent infection. If the rash continues to spread, or if you develop swelling in your face, lips, or have any difficulty breathing, please seek immediate medical attention.

Allegra 120 (Fexofenadine) is an antihistamine and can help relieve runny nose, sneezing, or allergy-related symptoms, but it will not reduce fever or headache from a cold. Since your cold has lasted 8 to 9 days with fever and headache, it is best to see a doctor.

Hello. It sounds frustrating to deal with these unpredictable rashes, especially when they disrupt your evening or shower routine. Rashes triggered by water, heat, or temperature changes are often forms of hives (urticaria). Using fexofenadine (Allegra) is a very safe and common way to manage these symptoms. While taking it every two days works well for many, it is best to discuss a long-term plan with a doctor or allergist. They can help identify specific triggers and ensure your treatment is tailored safely for you. You're doing a great job managing this, and we can find a lasting solution together.

Since cetirizine already provides you with excellent 48-hour relief, it is a highly effective choice, though it can occasionally cause mild drowsiness. If minimizing sleepiness is your main goal, fexofenadine (Allegra) is the best option among those you mentioned. Fexofenadine is highly effective for urticaria and is widely known as the least sedating antihistamine. In contrast, hydroxyzine (Atarax) is very sedating, and Montex FX contains a combination you may not need. I recommend discussing a trial of fexofenadine with your doctor to see if it keeps you comfortable and fully alert.
