    Niacin may be harmful to the fetus of pregnant women, when taken in high doses for the treatment of high cholesterol or some other conditions. Niacin is excreted in breast milk. Talk to your doctor if you are pregnant or nursing. Do not take niacin if you have a stomach ulcer, severe liver disease, or active bleeding. The safe use of niacin in children has not been effectively studied and should be used with caution. Do not take this drug if you are allergic to niacin.

    Nicotinamide may lower blood sugar levels. Caution is advised when using herbs or supplements that may also lower blood sugar. Blood glucose levels may require monitoring, and doses may need adjustment.

    Nicotinamide may increase the risk of bleeding, particularly in hemodialysis patients, when taken with herbs and supplements that are believed to increase the risk of bleeding. Multiple cases of bleeding have been reported with the use of Ginkgo biloba, and fewer cases with garlic and saw palmetto. Numerous other agents may theoretically increase the risk of bleeding, although this has not been proven in most cases.

    Nicotinamide may increase the amount of drowsiness caused by some herbs or supplements, such as sedatives. Caution is advised if driving or operating heavy machinery.

    Nicotinamide may lower blood pressure. Caution is advised in people taking herbs or supplements that lower blood pressure.

    Nicotinamide may interfere with the way the body processes certain herbs or supplements using the liver's cytochrome P450 enzyme system. As a result, the levels of other herbs or supplements may change in the blood. It may also alter the effects that other herbs or supplements potentially may have on the P450 system.

    Nicotinamide may also interact with antianxiety herbs and supplements, anti-inflammatory herbs and supplements, gastrointestinal herbs and supplements, herbs and supplements that may damage the liver, herbs and supplements that affect the immune system, or phosphorus.

    Despite the fact that niacin has demonstrated better overall results than statins in reducing risk factors for coronary heart disease, physicians are often reluctant to recommend niacin except in the form of the time-released prescription product Niaspan. The reason is a widespread perception by doctors that over-the-counter regular niacin is difficult to work with because of a bothersome flushing of the skin -- like a prickly heat rash -- which typically occurs 20 to 30 minutes after the niacin is taken and disappears in about 20 to 30 minutes more. Other occasional side effects of niacin include gastric irritation, nausea, and liver damage.

    One main reason why niacin is not recommended more by doctors is that it is a widely available generic agent available over the counter in health food stores and drugstores, so no pharmaceutical company stands to enjoy the huge profits that the other lipid-lowering agents have generated. As a result, niacin does not get the intensive advertising that the statin drugs have been given. Despite the advantages of niacin over other lipid-lowering drugs, the prescription form, Niaspan, accounts for less than 10 percent of all cholesterol-lowering prescriptions.

    If you are taking vitamin B3 on a regular basis, try to take it at the same time every day -- preferably with meals -- and at least eight ounces of cool water according to your doctor's or the label's instructions. Taking a nonsteroidal anti-inflammatory like aspirin one half hour before taking B3 may reduce side effects of skin irritation and flushing. Do not take B3 with hot liquids, or you will probably experience more side effects. If you take the extended-release tablet before going to bed, take it with a snack and at least eight ounces of cool water. Be sure to swallow it without chewing, and do not break it beforehand.

    Scientific information is lacking on the use of nicotinamide at levels greater than the recommended dietary allowance (RDA) of 17-18 milligrams in pregnant or breastfeeding women.

    Vitamin B3, also known as niacin, commonly causes side effects such as feeling flushed, itching or redness of the skin. Alcohol and hot drinks may increase these side effects. To reduce flushing reactions, try taking this medicine with a cool drink. You may also feel dizzy when taking vitamin B3, or it may cause an allergic reaction. Some people may notice that vitamin B3 causes insomnia. But such side effects of vitamin B3 may fade as you consume it on a regular basis.
