Boric Acid: Uses, Dosage and Side Effects

Boric acid is a natural compound used for its antifungal, antibacterial, and antiviral properties. It is commonly found in powder, tablet, and ear drop forms. People use boric acid to treat minor cuts, yeast infections, eye irritation, and ear infections.

It's also used as an insect repellent and in some cleaning products. Though helpful in small amounts, boric acid must be used carefully, as improper use or high doses can cause harmful side effects.

What is Boric Acid?

Boric acid effectively treats and prevents yeast infections by balancing vaginal acidity, thereby relieving symptoms such as itching and burning. It's beneficial for infections resistant to standard treatments. If initial treatments fail, a doctor may suggest boric acid or alternative medications, such as nystatin or flucytosine.

Benefits and Uses of Boric Acid

Boric acid is widely used due to its antifungal, antibacterial, and antiviral properties. It is available in various forms, including powder, tablets, and ear drops. It helps treat a variety of infections and minor irritations.

Conditions Boric Acid Treats

• Vaginal yeast infections (using boric acid suppositories)
• Ear infections (as boric acid ear drops)
• Minor cuts, wounds, or skin irritations
• Eye infections (in very diluted form)

Secondary Uses of Boric Acid

• Used as an insecticide to kill ants and cockroaches
• Added to foot soaks for fungal infections like athlete's foot
• Used in some household cleaners and preservatives

How Does Boric Acid Work?

Boric acid works by interfering with the growth and survival of bacteria and fungi. It damages their cell walls, stops them from multiplying, and creates an acidic environment that makes it hard for them to live. This helps reduce infections and irritation.

When used as an insecticide, boric acid affects the insects digestive system and causes dehydration, eventually killing them. It is effective but should be used carefully and only as directed to avoid harmful effects.

Boric Acid Dosage

The dosage of boric acid depends on the form and the condition being treated. For vaginal yeast infections, boric acid suppositories (usually 600 mg) are inserted once daily for 714 days. For ear infections, a few drops of boric acid solution may be used 23 times daily, as advised by a doctor. Boric acid powder for skin use should be applied in small amounts to the affected area, and only for short-term use.

What Should I Do If I Miss a Dose?

If you miss a dose, apply or insert it as soon as you remember. If it's almost time for the next dose, skip the missed one. Do not use extra boric acid to make up for a missed dose. Follow your doctors instructions closely.

What Happens If an Overdose Occurs?

Overuse or accidental swallowing of boric acid can be dangerous. It may lead to symptoms such as:

• Nausea or vomiting
• Diarrhea
• Skin rash
• Headache
• Confusion or weakness

In case of suspected overdose, seek immediate medical help. Long-term or excessive use, especially on broken skin, may lead to toxicity.

Drug Interactions and Storage of Boric Acid

Always inform your doctor about any medications you ' re using, including prescription drugs, over-the-counter creams, or ointments.

Interactions with Supplements and Herbal Products

Although rare, combining boric acid with strong herbal treatments or essential oils might increase skin irritation or reduce effectiveness. Avoid mixing it with products that cause dryness or burning unless your doctor approves.

How Should Boric Acid Be Stored?
