For your sneezing and watery eyes, an over-the-counter non-drowsy antihistamine like Loratadine (Claritin), Cetirizine (Zyrtec), or Fexofenadine (Allegra) is highly effective. The weakness you feel is a common allergic response, but it can be worsened by older, sedating antihistamines (like Benadryl), so avoid those during the day. For your eyes, lubricating eye drops can provide quick relief. Ensure you stay well-hydrated and get plenty of rest. Please consult a doctor or pharmacist before starting any medication to ensure it is safe for you, especially if your weakness worsens.

Your symptoms suggest an allergic reaction that may be triggering bronchospasm or allergic asthma. Because you are experiencing chest heaviness and wheezing, you need an immediate medical evaluation. A doctor may prescribe a rescue bronchodilator inhaler (such as Albuterol) to quickly open your airways, alongside oral antihistamines (like Cetirizine) or steroid nasal sprays for the sneezing and runny nose. Please do not self-medicate, as wheezing requires professional assessment. Seek urgent medical care or consult your physician right away.
