For those that take Niacin with the GABA have you experienced any of these side-effects?
What are the common side effects
Flushing of the skin (most common)
Itching or tingling of the skin
*
Skin rash
Call your doctor if the skin rash is severe or persists. It may be necessary to stop taking the niacin.
Headaches
Gastrointestinal (stomach/intestine) upset
Take niacin with food at breakfast, lunch and dinner to prevent stomach upset.
Your body will adjust to niacin within 3 to 6 weeks and the side effects will greatly decrease.
What can I do to reduce the flushing side effect?
Take one-half of an adult-size aspirin 20 minutes before each dose of niacin. (Do not take aspirin if you are on Coumadin.) You may only need to take the aspirin for 3 to 4 weeks until your body adjusts to the niacin.
Do not drink alcohol, take a hot bath or expose your skin to the sun; these make the flushing worse.
If you are going out to dinner and you don't want to experience a "flush," take your dose of niacin as soon as you get home.
If the flushing is getting worse, do not increase your dose. Take your current dose for a few more days to allow your body more time to adjust. If the flushing becomes too uncomfortable, decrease your dose by one or two tablets and stay with that dose. Call your doctor and tell him or her what dose you are taking.
What are some other side effects
Increased blood uric acid levels which can bring on symptoms of gout if you've had gout in the past*
Increased blood sugar levels*
Darkening of the skin in the armpits and groin area (rare)
Inflammation of the liver, and rarely liver problems*
*Blood tests are taken every 6 to 12 weeks for the first 15 months of niacin therapy. These blood tests monitor uric acid, blood sugar, liver enzymes and blood lipids to prevent the side effects listed above and to monitor the effectiveness of therapy.
