Hybrids have been called a âbridgeâ toward pure electric vehicles. In other words, they are a compromise, so another qualifier is they can be considered good, better, and best compromises. All gas-electric hybrids utilize some size of battery pack and electric motor.
Antibiotics for Sinus Infections. If symptoms don't resolve in seven to 10 days, are severe, or get worse after 10 days, your doctor may prescribe antibiotics. However, most cases of viral sinusitis resolve without treatment, and bacterial infection occurs in only a very small number of cases.
Chronic sinusitis. When using antibiotics to treat chronic (long-term) sinusitis, it may be helpful to remember that: 1  The number of days you take antibiotics depends on your general health, how serious your sinusitis is, and the type of antibiotic you are taking. The choice of antibiotic often depends on which antibiotics have worked well for you in the past. 2  If an antibiotic normally used to treat your sinusitis was successful in the past, it may be used again.
