From mid March to May, it is the "hardest hit area" for spring allergies. Poplar, willow, and cypress trees have high pollen concentrations, which can float far away and be invisible, making people unknowingly vulnerable. Although there isn't much pollen in rapeseed flowers and cherry blossoms, they can't resist getting closer and taking a photo... Even though their physical defenses are full, they still can't be stopped? Then we have to resort to 'chemical weapons'. What should be used for itchy eyes? What should I spray when my nose is blocked? What kind of antihistamine should I take if I feel uncomfortable all over my body? Clear explanation in one article! 1、 Itchy eyes? Use it! Are your eyes itching so much that you want to "pick them out and wash them"? You may be missing a bottle of the right eye drops. Common medications used to alleviate allergic conjunctivitis include: Emestine Fumarate Eye Drops, Pimelostat Potassium Eye Drops, Olotadine Hydrochloride Eye Drops, etc. If the symptoms are severe and other medications are ineffective, fluorometholone eye drops or tobramycin dexamethasone eye drops can be used. The duration of medication should not be too long, and contact lenses should not be worn during use. Eye drops are prone to contamination after opening, and should generally be used up within 4 weeks after opening. 2、 Nose blockage? Use it! It's like a renovation team living in my nose. Sometimes it itches so much, sometimes it gets blocked tightly, and sneezes come at any time, with three consecutive attacks. Relying solely on hard work is not enough, we need to provide it with 'means'. Preventive medication includes sodium succinate, ketotifen, etc., which can prevent the release of histamine and other allergic mediators, produce anti allergic effects, and are commonly used to treat allergic rhinitis, bronchial asthma, etc. It should be started as a preventive medication 2 weeks before the dissemination of allergenic pollen. The relief effect is limited for acute allergic symptoms that have already occurred. For patients with moderate to severe allergic rhinitis, representative drugs include budesonide nasal spray, mometasone furoate nasal spray, fluticasone propionate nasal spray, etc. These drugs have strong local anti-inflammatory effects, directly acting on the nasal mucosa, with minimal systemic absorption and mild adverse reactions. It is recommended to use it in the morning and follow the doctor's advice for long-term medication to achieve the best therapeutic effect. There is also a common medication: Montelukast Sodium, which can effectively alleviate nasal and asthma symptoms. For patients with allergic rhinitis, it can be taken in the morning. For asthma patients, it is recommended to take it before bedtime every day. Be cautious that Montelukast sodium can induce serious neurological and psychiatric adverse reactions (such as depression and suicidal tendencies), and inform the physician when relevant symptoms occur during medication. 3、 Feeling uncomfortable all over? Eat it! 4、 When using medicine scientifically, we must remember these three points. 1. Patience takes effect. Do not change the medicine frequently. Antiallergic drugs take effect quickly or slowly. For example, nasal sprays need to be used continuously for several days before they can take effect. Rushing to change medication after one or two days without any effect can actually delay treatment. 2. Symptom relief, do not stop taking medication without authorization. After the acute allergy symptoms subside, it is recommended to continue taking medication for 3-7 days to consolidate the therapeutic effect; Chronic allergies require long-term and regular medication according to medical advice, and should not be discontinued on one's own. 3. Reasonable combination use, do not blindly stack similar anti allergic drugs. Combination use will not enhance efficacy, but only increase adverse reactions. Taking antihistamines together with compound cold medicine can easily lead to excessive ingredients, causing discomfort such as drowsiness and palpitations.
