Cefdinir dispersible tablets have a drug specification of 0.1g per tablet, and adults should take 1 tablet each time, 3 times a day for effective anti-infection treatment according to the instruction. Cefdinir belongs to the third generation of cephalosporins, which has a broader antibacterial spectrum than the second generation of cephalosporins. In addition to being effective against Gram-positive bacteria, it also has a strong bactericidal effect against Gram-negative bacteria and Pseudomonas aeruginosa, and is often used for more serious infections, or for patients whose anti-infective effect is not good after using the first and second generation of cephalosporins. Alcohol is prohibited during the use of cefdinir, and the combination of the two can cause disulfiram reactions, which commonly include nausea, vomiting, facial flushing, and in severe cases, a drop in blood pressure, which can endanger the patient’s life, so special attention is needed during the medication period, and alcohol is generally allowed only after 6 days of discontinuation.
