Precautions & warnings
What should I know before using Bristopen® (Oxacillin)?
Before using oxacillin, tell your doctor if:
- You are allergic to any ingredient in oxacillin or any other penicillin antibiotic (e.g., amoxicillin).
- You are taking a tetracycline antibiotic (e.g., doxycycline).
- You take oxacillin before you receive any medical or dental care, emergency care, or surgery.
- You are pregnant, planning to become pregnant, or are breastfeeding.

- You are allergic to corn or corn products.
Also, you should know that:
- Oxacillin only works against bacteria; it does not treat viral infections (e.g., the common cold).
- Be sure to use oxacillin 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 oxacillin 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.
- 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.
- Oxacillin may reduce the number of clot-forming cells (platelets) in your blood. Avoid activities that may cause bruising or injury. Tell your doctor if you have unusual bruising or bleeding. Tell your doctor if you have dark, tarry, or bloody stools.
- Hormonal birth control (e.g., birth control pills) may not work as well while you are using oxacillin. To prevent pregnancy, use an extra form of birth control (e.g., condoms).
- Lab tests, including kidney or liver function tests, complete blood cell counts, or blood electrolyte levels, may be performed while you use oxacillin. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
- Use oxacillin with caution in the elderly; they may be more sensitive to its effects.
- Oxacillin should be used with extreme caution in children; safety and effectiveness in children have not been confirmed.
- Use oxacillin with extreme caution in children younger than 10 years old who have diarrhea or an infection of the stomach or bowel.
