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.

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.

It is very common for sinus symptoms to return after stopping fexofenadine (Allegra), as it manages symptoms rather than curing the underlying inflammation. Since you had nasal surgery ten years ago, structural changes or chronic allergies might be at play. For long-term relief, daily saline nasal rinses and generic corticosteroid nasal sprays (like fluticasone) are often highly effective and safe for ongoing use. I gently recommend consulting an ear, nose, and throat (ENT) specialist or an allergist.

Regarding his medications, both Ibugesic Plus and Ibugesic contain ibuprofen. Giving both, alongside Allegra and T-Minic, risks an accidental overdose of similar active ingredients. I highly recommend consulting his pediatrician to safely review this drug combination and get the correct dosages tailored for his weight. For now, keep him comfortable and well-hydrated to help his body naturally fight off the virus.

It is generally very safe for you to receive the Covishield vaccine while continuing your Allegra 180 (fexofenadine) and Formonoid 200 (budesonide/formoterol) inhaler. These medications will not interfere with how the vaccine works or increase your risk of side effects. In fact, keeping your hives well-controlled is important for your comfort and overall well-being. Please do not stop your routine medications before getting vaccinated. As a standard precaution, let the vaccination staff know about your medications and stay at the center for 30 minutes after your shot for routine observation.
