Antiprotozoals are not a type of antimicrobial agent. They are used to treat infections caused by protozoa, which are single-celled organisms.

Penicillin is an antibiotic that is used to treat bacterial infections. It works by inhibiting the synthesis of bacterial cell walls.

Acyclovir is an antiviral drug that is used to treat herpes simplex virus infections. It works by inhibiting the replication of the virus.

Fluconazole is an antifungal drug that is used to treat candidiasis. It works by inhibiting the synthesis of fungal cell walls.

Chloroquine is an antiparasitic drug that is used to treat malaria. It works by inhibiting the growth of the malaria parasite in red blood cells.

Nausea, vomiting, and diarrhea are all common side effects of antibiotic therapy. These side effects are usually mild and go away after a few days.

Headache, fatigue, and nausea are all common side effects of antiviral therapy. These side effects are usually mild and go away after a few days.

Skin rash, nausea, and vomiting are all common side effects of antifungal therapy. These side effects are usually mild and go away after a few days.

Headache, fatigue, and nausea are all common side effects of antiparasitic therapy. These side effects are usually mild and go away after a few days.

Anaphylaxis, Stevens-Johnson syndrome, and toxic epidermal necrolysis are all serious side effects of antibiotic therapy. These side effects are rare, but they can be fatal.

Hepatotoxicity, nephrotoxicity, and cardiotoxicity are all serious side effects of antiviral therapy. These side effects are rare, but they can be fatal.

Hepatotoxicity, nephrotoxicity, and cardiotoxicity are all serious side effects of antiparasitic therapy. These side effects are rare, but they can be fatal.

Overuse, underuse, and misuse of antimicrobial agents are all common causes of antimicrobial resistance. Overuse of antimicrobial agents can lead to the development of resistant bacteria, underuse of antimicrobial agents can lead to the development of resistant viruses, and misuse of antimicrobial agents can lead to the development of resistant fungi and parasites.

Using antimicrobial agents only when necessary, using antimicrobial agents for the correct duration of time, and using antimicrobial agents at the correct dose are all strategies for preventing antimicrobial resistance.
