Re: Cured my peeling lips/Exfoliative Cheilitis via Niacin in megadoses...

Is it safe to take that much? The recommended dose is 500Mg a day!

Side Effects:

"This medication may cause flushing and a feeling of warmth about the face and neck within the first two hours of taking a dose. Itching, tingling, or headache may occur as well. These effects should subside as your body adjusts to the medication. Stomach upset, heartburn, nausea, vomiting, and diarrhea may also occur. Report promptly any of these effects if they persist or worsen. Unlikely but report promptly: vision problems, dark urine, stomach (abdominal) pain, yellowing eyes or skin, irregular heartbeat, black stools, increased urination, muscle aches/pains. In the unlikely event you have an allergic reaction to this drug, seek immediate medical attention. Symptoms include: rash, swelling, dizziness, fainting, trouble breathing. To minimize the flushing effect (redness, itch) take a plain (not enteric-coated) 325 mg aspirin tablet (or other NSAIDs such as ibuprofen) 30 minutes before each niacin dose. After a few weeks, this flushing effect should stop occurring, or decrease in intensity. Also, avoid alcohol or hot beverages near the time of the niacin dose. Consult your doctor or pharmacist. If you notice other effects not listed above, contact your doctor or pharmacist."
