Primsol

Primsol is an antibiotic that treats bladder or kidney infections, as well as ear infections caused by specific bacteria.

Primsol may also be used for other reasons not mentioned in this medication guide.

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Measure liquid medicine carefully. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).

Use Primsol for the full prescribed length of time, even if your symptoms quickly improve. Skipping doses can increase your risk of infection that is resistant to medication. This medicine will not treat a viral infection such as the flu or a common cold.

This medicine can affect the results of certain medical tests. Tell any doctor who treats you that you are taking Primsol.

Store at room temperature away from moisture, heat, and light.

You should not use Primsol if you have anemia caused by a folate (folic acid) deficiency.

You should not use Primsol if you are allergic to it, or if you have:

• anemia (low red blood cells) caused by a folate (folic acid) deficiency.

Primsol is not approved for use by anyone younger than 2 months old. This medicine should not be used to treat an ear infection in a child younger than 6 months old.

Tell your doctor if you have ever had:

• a folate deficiency;
• liver or kidney disease; or
• a blood disorder.

Tell your doctor if you are pregnant. Primsol can interfere with your body's ability to metabolize folic acid, which is important for the development of the unborn baby's brain and spinal cord.

It may not be safe to breastfeed while using this medicine. Ask your doctor about any risk.

Get emergency medical help if you have signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

• fever, weakness;
• sore or swollen tongue;
• easy bruising, purple or red spots under your skin;
• a skin rash, no matter how mild; or

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Take the medicine as soon as you can. If it is almost time for your next dose, skip the missed dose. Do not take two doses at the same time.

Seek emergency medical help or call the Poison Help line at 1-800-222-1222.

Symptoms of an overdose may include nausea, vomiting, headache, dizziness, confusion, depression, fever, chills, or flu-like symptoms.

An overdose can happen gradually over a long time if your daily doses are too high.

Antibiotic medicines can lead to diarrhea, which may indicate a new infection. If you have diarrhea that is watery or bloody, call your doctor before taking anti-diarrhea medicine.

Other drugs may affect Primsol, including prescription and over-the-counter medicines, vitamins, and herbal products. Inform your doctor about all your current medicines and any medicine you begin or stop using.
