- Probenecid because it may increase the risk of Amoxil's side effects

This may not be a complete list of all interactions that may occur. Ask your health care provider if Amoxil may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.
How to use Amoxil:
Use Amoxil as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- Take Amoxil by mouth with or without food. If stomach upset occurs, take with food to reduce stomach irritation.
- To clear up your infection completely, take Amoxil for the full course of treatment. Keep taking it even if you feel better in a few days.
- If you miss a dose of Amoxil, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.
Ask your health care provider any questions you may have about how to use Amoxil.
Important safety information:
- Amoxil may cause dizziness. This effect may be worse if you take it with alcohol or certain medicines. Use Amoxil with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
- Amoxil only works against bacteria; it does not treat viral infections (eg, the common cold).
- Be sure to use Amoxil 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 Amoxil 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.
- Do not receive a live vaccine (eg, oral typhoid vaccine) while you are taking Amoxil. Talk with your doctor before you receive any vaccine.
- Hormonal birth control (eg, birth control pills) may not work as well while you are using Amoxil. To prevent pregnancy, use an extra form of birth control (eg, condoms).
- Brown, yellow, or gray tooth discoloration has occurred rarely in some patients taking Amoxil. It occurred most often in children. The discoloration was reduced or removed by brushing or dental cleaning in most cases. Contact your doctor if you experience this effect.
- Diabetes patients - Amoxil may cause the results of some tests for urine glucose to be wrong. Ask your doctor before you change your diet or the dose of your diabetes medicine.
- Lab tests, including liver function, kidney function, and complete blood cell counts, may be performed if you use Amoxil for a long period of time. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
- Caution is advised when using Amoxil in CHILDREN younger than 3 months old; they may be more sensitive to its effects.
- PREGNANCY and BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using Amoxil while you are pregnant. Amoxil is found in breast milk. If you are or will be breast-feeding while you use Amoxil, check with your doctor. Discuss any possible risks to your baby.
