Zinc Protein Complex is not effective for prostatitis. Zinc Protein Complex is a health supplement and is not effective in the treatment of prostatitis. The treatment of prostatitis needs to go to the regular hospital for a clear diagnosis, under the guidance of the doctor to carry out the appropriate treatment. Prostatitis is divided into acute bacterial prostatitis (type I), chronic bacterial prostatitis (type II), chronic prostatitis (type III), and asymptomatic prostatitis (type IV). Type I prostatitis should be treated with bed rest, plenty of water, and antipyretic and analgesic treatment. The rational application of antibiotics is the key to treating prostatitis. When the germs are not identified, broad-spectrum antibiotics (ampicillin, etc.) should be used intravenously, and the therapeutic drugs should be changed after bacterial culture. Type II and III prostatitis should be treated with antibiotics that are sensitive to the bacteria for at least 6 weeks, and also with hot water sitz baths and prostate massage. Ampicillin adverse reactions are mostly allergic reactions, rash is more common, mostly urticaria or maculopapular rash, interstitial nephritis or anaphylactic shock can also occur. It should be contraindicated for those who are allergic to the drug.
