Boils – Causes, Symptoms and Treatment

A Boil is a bacterial infection, that develops around a hair follicle. It is filled with pus. Boils are contagious in nature, and can cause potential problems if the infection spreads.

Starting out as a tender, red bump which is soft in consistency, a boil eventually develops a yellowish peak which is hard and stiff within 3-4 days. Itching and irritation will be experienced around a boil.

Also known as Furuncles, these are very painful, especially when they occur in areas that cannot be freely moved. A boil eventually bursts open, and the pus oozes out, thus relieving the pain.

In case of big boils, it is best to consult with a physician, who, upon proper examination will decide a course of action.

Now lets see some of the prescription drugs for boils...

Prescription Drugs For Boils

Prescription drugs can also be purchased from over the counter to help relive the pain from boils.



Benzocaine is a local anesthetic ointment. It helps numb the pain caused by the boil. Only a small amount of benzocaine is required to help ease the pain.

Method Of Application: Benzocaine is applied topically, directly on the boil.

Mechanism of Action: Benzocaine blocks the transmission of the pain signal.

Side Effects: Benzocaine can cause respiratory failure, seizures, arrhythmia ( inconsistent rhythm of the heart) and may lead to coma when an excessive amount of the medication enters the circulatory system (blood) through the skin.

Benzocaine must always be used as directed by the physician.



This drug is also a topical antibiotic. It is primarily used for treating the boils. When this drug is formulated at a high concentration, it kills bacteria because of its antibiotic properties.

This drug is also very effective against Methicillin-Resistant Staphylococcus Aureus.

Directions: This ointment must be applied 2-3 times a day, directly on the boil. Only a small amount is sufficient for effective results. The boils regress within 2 weeks.

Side Effects: Prolonged or indiscriminate use of this drug may lead to antibiotic resistance against Mupirocin.

Other side effects include pain, burning or stinging sensation, itching and rashes on the skin.

This ointment is generally prescribed in patients with chronic illness. Such people carry the bacteria in their nasal passages or their groins, and continuously get re-infected leading to recurrent boils.



This is a broad spectrum antibiotic ointment used for treating boils.

This drug can easily heal the infected skin when applied thrice a day to the boil, in a small amount.

Gentamicin ointment use must be limited to two weeks as prolonged usage may increase the risk of developing resistance against this antibiotic.

Antibiotics for Boil Treatment

Oral antibiotics in the form of capsules are primarily prescribed for boils that have developed in sensitive regions of the body, like the genitals, face etc.

These antibiotics are particularly useful when the infection has spread far and deep in the skin, or with a secondary infection such as cellulitis.



Penicillin based antibiotics like amoxicillin-clavulanate, flucloxacillin etc. are widely prescribed by physicians and dermatologists to treat boils. These antibiotics are taken 4 times a day, usually an hour before or two hours after the meals.

NOTE: Whenever such antibiotics are prescribed for treating infections, the full course must be finished to prevent building resistance to the drug or recurrent infections.

Side Effects: Penicillin based antibiotics may cause diarrhea, joint pain, rashes on the skin, liver problems, fever etc. People with the history of penicillin allergy must strictly avoid these drugs.


Macrolide Antibiotics

Drugs like erythromycin are prescribed in patients who have a penicillin allergy.

These antibiotics are used to treat the infections and are usually taken 4 times a day. The severity of the infection determines the course of treatment.

NOTE: This medication should not be taken with or immediately after consumption of aerated beverages.

Side Effects: Diarrhea, vomiting, stomach ache, upset stomach, cramps, skin rashes etc.

Other Tips and Treatment Guidelines

Do not squeeze or try to rupture the boil on your own as it may cause the infection to spread. Usually, the boils heal on their own, but if that does not happen, consult with your physician or dermatologist.

Your doctor will most likely cut it open to allow the contents to ooze out. If the boil is considerably large in size, the doctor may pack the remaining cavity with a gauze piece. The doctor may then prescribe an antibiotic ointment to apply on the wound.

  • Make sure that you wash any towels, clothes or compresses that you have touched the boil with. This will minimize the chances of spreading the infection.
  • If your boils are accompanied by fever, chills, malaise and/ or enlarged lymph nodes, it's best to seek medical advice instead of resorting to home based remedies.
  • In the case of recurrent boils with a medical history of fever, malaise, chills, or if you are immunocompromised- the doctor may perform a bacterial culture test to determine which bacteria have led to the infection and then prescribe antibiotics accordingly.
  • Very ill patients or those with underlying medical problems may be required to be hospitalized. Such patients are generally given intravenous (I.V.) antibiotics.
  • If a boil develops around the lips or the mouth, generally, surgical drainage is not performed. This is because, in such cases, there is a high risk of the infection spreading to the brain.


Boils have been a problem since the beginning of time. Till today, even the sight of boils makes people cringe. But the good thing is, although boils look awful and a painful, most of them are usually harmless.

They usually stick around for a few weeks and then gradually regress on their own. With proper maintenance of hygiene, boils can be easily prevented. And if you do end up getting them, they can be treated using some basic home remedies.

And if you have bigger underlying infections, physicians are always there to help control the condition.
