A runny nose or yellow-green mucus does not usually indicate, a bacterial infection. Antibiotics can and will be used for infections that are severe or last more than two weeks. As with any drug, there are certain possible side effects that may occur when using antibiotics. Antibiotics can cause unfavorable reactions such as, nausea, diarrhea, and stomach pain. Some people experience an allergic reaction that can be characterized by a rash and itching, or difficulty breathing in severe cases.
Some antibiotics kill naturally occurring bacteria that are needed by the body.
In these instances bacteria that can cause diarrhea or yeast infections replace the good bacteria. People experiencing any adverse reactions after taking antibiotics should contact a health care provider immediately. Antibiotics have been around for many years. They were once considered to be a miracle cure, and they continue to provide significant benefits when used wisely. Your provider will determine what form of treatment is best suited for your illness and related symptoms.
