Important Cravit Safety Information
- Cravit may cause dizziness or lightheadedness. These effects may be worse if you take it with alcohol or certain medicines. Use Cravit with caution. Do not drive or perform other possible 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.
- Cravit only works against bacteria; it does not treat viral infections (eg, the common cold).
- Be sure to use Cravit 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 Cravit 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.
- Tell your doctor right away if you experience pain or swelling of a tendon or weakness or loss of use of a joint area. Rest the area and avoid exercise until further instruction from your doctor.
