Alphamox is used for treating infections caused by certain bacteria. Alphamox is a penicillin antibiotic. It works by killing sensitive bacteria.
Use Alphamox as directed by your doctor.
- Take Alphamox by mouth with or without food. If stomach upset occurs, take with food to reduce stomach irritation.
- To clear up your infection completely, take Alphamox for the full course of treatment. Keep taking it even if you feel better in a few days.
- If you miss a dose of Alphamox, 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 Alphamox.
Store Alphamox at or below 77 degrees F (25 degrees C). Store away from heat, moisture, and light. Do not store in the bathroom. Keep Alphamox out of the reach of children and away from pets.

Important Alphamox Safety Information
- Alphamox may cause dizziness. This effect may be worse if you take it with alcohol or certain medicines. Use Alphamox with caution. Do not drive or perform other possible unsafe tasks until you know how you react to it.
- Alphamox only works against bacteria; it does not treat viral infections (eg, the common cold).
- Be sure to use Alphamox 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 Alphamox 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.
- Hormonal birth control (eg, birth control pills) may not work as well while you are using Alphamox. 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 Alphamox. 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 - Alphamox 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 Alphamox 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.
- Use Alphamox with caution in the elderly; they may be more sensitive to its effects, especially patients with kidney problems.
- Use Alphamox with extreme caution in children younger than 10 years old who have diarrhea or an infection of the stomach or bowel.
- Alphamox should not be used in children who weigh less than 88 lbs (40 kg); safety and effectiveness in these children have not been confirmed.
- Pregnancy and breast-feeding: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using Alphamox while you are pregnant. Alphamox is found in breast milk. If you are or will be breast-feeding while you use Alphamox, check with your doctor. Discuss any possible risks to your baby.
