Shingles is a viral infection caused by the varicella-zoster virus. It causes a painful rash to develop along an isolated area of the skin. Anyone who's had chickenpox is susceptible to developing shingles, since the same virus is responsible for both conditions. While treatment often relies on prescription medications, some people turn to self-care measures to relieve symptoms of the condition. Folic acid isn't usually one of them. Talk to your doctor before taking any dietary supplement to treat this or any other condition.
Folic Acid
Any evidence that folic acid can improve symptoms associated with shingles is anecdotal at best. Neither the National Institute of Neurological Disorders and Stroke nor the National Institute of Allergy and Infectious Diseases makes mention that this B-vitamin can in anyway improve shingles. In fact, dietary changes are not known to prevent or treat an occurrence. Folic acid --- or any other nutrient, for that matter --- does nothing to prevent or suppress the reactivation of the varicella-zoster virus.
Medications
The only time folic acid may be necessary is during the use of nonsteroidal anti-inflammatory drugs or NSAIDs, such as ibuprofen, naproxen or acetaminophen. According to the University of Maryland Medical Center, medical professionals may recommend taking a folic acid supplement when using this type of medication. NSAIDs can sometimes disrupt the absorption of folate. Ibuprofen and naproxen are commonly used to relieve pain associated with shingles, so a dietary supplement may be necessary to increase the level of folate in the body.
Dosage
Your doctor can tell you how much folic acid to take, but the recommended daily intake for adults is 400 mcg a day. Women who are pregnant or breastfeeding can take 600 mcg and 500 mcg, respectively. Taking more than this amount can lead to undesirable side effects, so consult with a medical professional.
Warning
Taking folic acid to treat any condition isn't without its own potential side effects. Though rare, high dose of this B-vitamin can lead to skin reactions, warns the University of Maryland Medical Center. This skin reaction, however, is not shingles and the two conditions are not related. You may also experience some stomach issues or sleep problems. Severe reactions may lead to seizures. Always talk to your doctor before taking this or any other supplement to improve symptoms of shingles.
