Important safety information:
- E.S.P. may cause dizziness. This effect may be worse if you take it with alcohol or certain medicines. Use E.S.P. with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
- Mild diarrhea is common with antibiotic use. However, a more serious form of diarrhea (pseudomembranous colitis) may rarely occur. This may develop while you use the antibiotic or within several months after you stop using it. Contact your doctor right away if stomach pain or cramps, severe diarrhea, or bloody stools occur. Do not treat diarrhea without first checking with your doctor.
- E.S.P. only works against bacteria; it does not treat viral infections (eg, the common cold).
- Be sure to use E.S.P. for the full course of treatment. If you do not, the medicine may not clear up your infection completely. The bacteria could also become less sensitive to this or other medicines. This could make the infection harder to treat in the future.
- Long-term or repeated use of E.S.P. may cause a second infection. Tell your doctor if signs of a second infection occur. Your medicine may need to be changed to treat this.
- Infrequently, a serious stomach problem called infantile hypertrophic pyloric stenosis (IHPS) has been reported in infants taking erythromycin. Contact your child's doctor right away if severe vomiting or irritability with feeding occurs.
- Tell your doctor or dentist that you take E.S.P. before you receive any medical or dental care, emergency care, or surgery.
- Rarely, patients taking E.S.P. have developed reversible hearing loss. This risk is greater if you have kidney problems or you take high doses of E.S.P.. Contact your doctor if you develop decreased hearing or hearing loss.
- E.S.P. may cause you to become sunburned more easily. Avoid the sun, sunlamps, or tanning booths until you know how you react to E.S.P.. Use a sunscreen or wear protective clothing if you must be outside for more than a short time.
- E.S.P. may interfere with certain lab tests. Be sure your doctor and lab personnel know you are taking E.S.P..
- Lab tests, including liver function, kidney function, complete blood counts, and urinalysis, may be performed while you use E.S.P.. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
- E.S.P. should not be used in CHILDREN younger than 2 months old; safety and effectiveness in these children have not been confirmed.
- Use E.S.P. with caution in the ELDERLY; they may be more sensitive to its effects, especially irregular heartbeat (prolonged QT interval).
