For your runny nose and watery eyes, antihistamines like Allegra (fexofenadine) or Zyrtec (cetirizine) can help, but they won't relieve general cold symptoms. Sinarest, which contains paracetamol, a decongestant, and an antihistamine, is often more effective for a multi-symptom cold, though it may make you drowsy. Please do not combine these medications, as they contain overlapping ingredients. Rest, drink plenty of fluids, and please see a doctor if your symptoms worsen.

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.

Recovering from COVID-19 can sometimes leave your immune system temporarily reactive. It is reassuring that fexofenadine (Allegra) helped your rash; you can continue taking this antihistamine daily under medical guidance. For the fluid-filled bump on your forehead, please avoid squeezing it and keep it clean. For your painful, receding gums, warm salt water rinses and gentle brushing will help soothe the area. Because these symptoms affect different systems, I highly recommend having a doctor evaluate the forehead bump and rash, and a dentist examine your gums to ensure you receive the correct targeted treatments.

Since these antihistamines aren't helping, the rash might not be typical hives, or it may require a different treatment approach. I highly recommend having a healthcare provider examine the area. They can pinpoint the exact cause?whether it is contact dermatitis, an infection, or another skin condition?and prescribe a targeted therapy, like a prescription topical cream. For now, try applying cool compresses and wearing loose, breathable clothing to soothe the irritation. A doctor will help you find the right relief.

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.

Allegra 120 (fexofenadine) can help relieve itchy, watery eyes caused by seasonal allergies, but it is not specifically designed to treat red eyes. Redness can happen for many reasons, including dryness, irritation, or a minor infection. If allergies are the cause, over-the-counter antihistamine or lubricating eye drops often provide more direct relief. Since eyes are very delicate, it is a good idea to have a healthcare professional or eye doctor check them to find the exact cause of the redness and suggest the safest, most effective treatment for you.
