2. How to use Niaspan

Read the instructions given by your doctor carefully before you start taking Niaspan and each time you get a supplement. If you have any questions about how to use Niaspan, ask your doctor.
Niaspan is to be taken by mouth with a low-fat meal or snack as directed by your doctor, usually at bedtime. Taking Niaspan on an empty stomach increases the risk of side effects (such as flushing, upset stomach).
Do not crush or chew Niaspan slow release tablets. Doing so can cause all of the medication to be released at once, increasing the risk of side effects. Also, you should not split the tablets unless they have an index line and your doctor tells you to do so.
Niacin is available in different products. Do not switch between medicines with different concentrations, brands, or forms of niacin. Serious liver problems may occur if you do so.
Niaspan dosage is calculated based on your medical condition and response to treatment. To reduce your risk of side effects, your doctor may direct you to start Niaspan at a low dose and gradually increase your dose.
If you also take certain other medicines to lower cholesterol (such as cholestyramine or colestipol), take niacin at least 4-6 hours before or after taking these medicines. These products may react with niacin, preventing complete absorption of the drug. Continue taking other cholesterol-lowering medications as prescribed by your doctor.
To reduce your risk of Niaspan side effects such as flushing, avoid drinking alcohol, hot drinks, and eating spicy foods near the time you take niacin. Taking a regular aspirin or a nonsteroidal anti-inflammatory drug (such as ibuprofen, 200 milligrams) 30 minutes before taking niacin can help prevent flushing.
Use Niaspan medicine regularly to get the most benefit from it. To help you remember to take your medicine, take it at the same time each day.
Do not stop taking Niaspan without consulting your doctor. If you stop taking niacin, you may have to go back to your original dose and gradually increase it again. Ask your doctor for instructions on how to start again if you have not taken the medicine for a long time (more than 7 days).
It is very important in the treatment of high cholesterol to continue following your doctor's advice regarding diet and exercise.
Tests such as blood lipids, blood sugar, liver function tests should be performed periodically to monitor your progress or check for side effects during treatment with Niaspan.
