What medication is effective for trichomoniasis? Thank you for the doctor's answer.

Doctor's answer:

Metronidazole has few side effects. In some cases, nausea may recur after taking the medication, along with nausea, vomiting, dizziness, headache, rash, and granulocyte reduction. These side effects disappear after discontinuing the medication.
Topically, a 1% lactic acid or acetic acid solution can be used to rinse the external genital area and douche the vagina. Then, carbaryl or metronidazole or griseofulvin suppositories can be inserted into the vagina, along with topical Chinese herbal washes. Herbs such as Persicae Fructus, Sophorae Flavescentis Radix, Schoenoplecti Rhizoma, Cnidii Fructus, and Cimicifugae Rhizoma can be decocted for steam bathing and sitz baths.
During treatment, it is important to maintain constant local hygiene. Underwear and items that come into contact with the external genital area should be boiled to sterilize them and prevent reinfection.
