Nicotinic acid

About nicotinic acid

Nicotinic acid is used to lower levels of cholesterol and other lipids (fats) in the blood. Cholesterol is made naturally in the body and is absorbed from the food we eat. If levels of cholesterol are too high in the blood stream, it is deposited on the walls of blood vessels. Eventually this leads to a narrowing of the blood vessels and can even block them completely.

High levels of cholesterol do not make people feel ill but can cause problems if left untreated. This medicine may help prevent medical problems caused by cholesterol and fats building up in blood vessels, such as heart disease.

Laropiprant may be used in combination with nicotinic acid. Flushing is sometimes a side-effect of treatment with nicotinic acid, and laropiprant is used to help prevent this.

Before taking nicotinic acid

Before taking nicotinic acid make sure your doctor or pharmacist knows:

• If you are pregnant, trying for a baby or breast-feeding.
• If you suffer from liver problems, or have had jaundice.
• If you suffer from angina, heart disease, diabetes, gout or peptic ulcer (stomach ulcer).
• If you have ever had an allergic reaction to this or any other medicine.

How to take nicotinic acid

• Take nicotinic acid exactly as directed by your doctor.
• If you have been prescribed controlled release tablets that release the drug slowly to give a more even effect, do not divide, crush or chew them. This may cause too much drug to be absorbed too quickly.
• Take nicotinic acid with or immediately after food.
• Try to take nicotinic acid at the same time each day to avoid missing any doses.
• If you do miss a dose, take it as soon as you remember and continue taking it at the usual times. If it is nearly time for your next dose, leave out the missed dose, never take two doses at the same time to compensate.

Getting the most from your treatment

• Many people are able to control their condition by carefully following their doctor's directions for a healthy diet and exercise. Medicine is prescribed only when additional help is needed and nicotinic acid is only effective when a healthy diet is also followed.
• Nicotinic acid is less effective if you are greatly overweight. It may be very important for you to go on a weight reducing diet. However, check with your doctor before going on any diet.
• Even if you do not feel unwell, never stop taking nicotinic acid without checking with your doctor first. When you stop taking nicotinic acid, your fat levels may increase again.
• Do not smoke. Smoking tends to increase your cholesterol level and also puts a strain on the heart and circulatory system.
• Avoid drinking too much alcohol while you are being treated with nicotinic acid. Alcohol can also increase your cholesterol levels.
• Avoid drinking alcohol or hot drinks around the time you take your dosage. This will help prevent you feeling flushed and itchy.

Can nicotinic acid cause problems

Along with their useful effects all medicines can cause unwanted side effects, which usually improve as your body adjusts to the new medicine. Speak with your doctor or pharmacist if any of the following side effects continue or become troublesome.

How to store nicotinic acid
