Eye Infection
Example of Sulfonamide Used For Eye Infection. Sulfa drugs are used to treat a wide range of health problems. They are also used to prevent certain bacterial infections.
Sulfa drugs may cause an allergic reaction, which can include hives or a rash. These reactions happen most often with antibiotics. However, some nonantibiotic sulfa drugs can also cause allergic reactions.[1]
Uses
Sulfonamide is a drug used in the treatment of several types of infection. It is one of the first antimicrobials that were developed and continues to be an effective treatment for many infectious diseases. However, due to the development of resistance and adverse effects, sulfonamides are now being replaced by safer alternatives.[2]
The mechanism of action of sulfonamide drugs is based on their ability to inhibit the enzyme dihydropteroate synthetase (DHPS), which catalyses the conversion of para-aminobenzoic acid (PABA) into dihydropteroate. This process is essential for the biosynthesis of folic acid, which is needed by mammalian cells to synthesize DNA and RNA. Without DHPS, bacteria are unable to produce folic acid. This explains the selective toxicity of sulfonamide antibiotics to bacterial cells, as opposed to their bacteriostatic effect.
For example, sulfonamide can be used to treat superficial eye infections caused by susceptible organisms such as Staphylococcus aureus, Pneumocystis jirovecii, and Streptococcus pneumoniae. It is also used to prevent or treat ocular surface infections such as keratitis and corneal ulcers.
It is a safe and effective ophthalmic agent for the treatment of bacterial conjunctivitis, corneal ulcers, keratitis, and staphylococcal keratitis. The recommended dosage is a ribbon of ointment approximately 1 cm in length instilled into each lower conjunctival sac up to 6 times daily, as necessary. In addition, it may be used as prophylaxis for chlamydial or gonococcal conjunctivitis in newborns.
Sulfacetamide ophthalmic solution is a synthetic sulfonamide antibiotic that is used in the treatment of superficial ocular infection caused by susceptible organisms. It is an ideal sulfonamide for ophthalmic administration because it has a pH of 7.4. Sulfacetamide is available in a 30% solution and as a 10% lotion.[3]
Sodium sulfacetamide ophthalmic drops are the preferred ophthalmic preparation for treating superficial bacterial infections of the eye. It is a white, oily liquid with a pH of 7.4. The drops should be applied to the affected eye(s) up to twice a day. Taper the dose to once a day as the condition improves.
Sulfonamide is classified as a pregnancy category C medication, and should not be given to pregnant women or within the first few weeks of pregnancy because it can increase the risk of kernicterus in the newborn. In addition, it can cause jaundice and hemolytic anemia in the mother.
Precautions and Warnings
The precautions and warnings associated with sulfonamide use for eye infection include possible allergic reactions. These reactions can be mild or serious and can range from a rash to a life-threatening condition called anaphylaxis.
If you have a sulfa allergy, your doctor may tell you to start this medication slowly (called drug desensitization) or not to take it at all. This will help to reduce the risk of a serious reaction.[4]
It also will help your body become tolerant to the medication so that it won’t cause problems. This is especially important for people who have a history of severe reactions to sulfonamides.
Antibiotics that contain sulfonamide are used to treat many different health conditions from eye infections to rheumatoid arthritis. The most common side effects of these medications are a rash and an allergic reaction to the drug.
Usually, this reaction is harmless. But if you have a serious reaction, call your doctor right away.
These medications can be harmful if you have high blood pressure or if you’re pregnant. They can also make you drowsy or dizzy.
Sulfonamides also can affect your immune system and lower your white blood cell count. This can lead to organ damage, including the liver and lungs.
If you have a sensitivity to sulfonamide, tell your doctor right away. They can watch you closely for signs of a negative reaction and stop the medication if necessary.
Another possible complication of using sulfonamide for eye infection is a severe allergic reaction called Stevens-Johnson syndrome. This can be life-threatening and involves a sudden rash, fever, or swelling of your mouth, throat, or tongue. It can also cause trouble breathing and low blood pressure.[5]
This reaction usually happens about a week after you start taking the drug. It usually begins with a rash and itching on the skin. If it gets worse, you might need an injection of epinephrine.
It’s very important to tell your doctor if you have any other allergies or if you are pregnant before you use this drug. Sulfonamides can cause allergies in about 3 percent of people who take them.
Common Side Effects
Sulfonamide is a common medication used to treat a variety of bacterial infections. However, it can also cause allergic reactions in some people.[6]
A sulfa allergy is an immune system response that causes symptoms like itching, swelling, and redness of the eyes, throat, or skin. It can range from a mild reaction to a serious one that involves trouble breathing.
Itching is a common side effect of sulfonamide eye drops and other products that contain sulfonamide. It can be a mild to severe, temporary condition that usually goes away with treatment.
The sulfonamide component of sulfonamide drugs can cause the release of histamine, which can cause itching and redness. This may make it uncomfortable to wear contact lenses or glasses, and can cause a burning sensation in your eye or nose.
Other side effects from sulfonamide medications include blurred vision or a light-sensitive condition called photophobia. If these symptoms occur, you should call your doctor right away.
Sulfonamide can also increase the risk of thyroid gland tumors. This can happen in people who take sulfonamide for a long time, especially if they also have thyroid problems.[7]
In addition, sulfonamide can cause low potassium levels in the blood. This can lead to low blood pressure or seizures.
Many of the side effects associated with sulfonamide can be managed by taking extra water or other measures to lower your potassium levels. If you have other health problems, your doctor may recommend changing the amount of sulfonamide that you take.
Benzocaine, dapsone, acebutolol, and procainamide can all cause side effects like itching, rashes, or swelling of the face. This is because they contain an arylamine group that can bind to immunoglobulin E (IgE) and trigger an allergic reaction in some people.
The sulfonamide compound in these medications can also be changed to a more acidic substance, which can make them less effective. In this case, it is important to avoid these drugs if you have a sulfonamide allergy or kidney disease.
Sulfonamide can be used to treat a variety of bacterial eye infections. It can be used as an eye drop or taken orally. It is also available in a cream form that can be applied to the eyes.[8]
Drug Interactions
Sulfonamide is a drug that can be used to treat a variety of eye infections. It works by inhibiting bacterial dihydrofolate synthetase. This is important because bacterial dihydrofolic acid is needed for growth. If you have a history of liver problems, or if you are taking medications that can cause liver problems, tell your doctor before using sulfonamide. Sulfonamides also can cause birth defects if you are pregnant or breast-feeding.
A sulfonamide allergy is a reaction to sulfa drugs (antibiotics and other medicines). It usually starts with red, itchy skin that looks like a rash. It may spread to other parts of your body and cause fever and organ problems. It can happen a few weeks after you start the medication.
Many people are allergic to sulfa drugs. Some people have severe reactions that require hospitalization or surgery. The most common symptoms include a fever, swelling, and a rash that covers large areas of your body. If you have a sulfa drug allergy, your doctor can take you off the medicine and give you other treatment.[9]
You should not use sulfonamide if you have kidney disease or if you are taking diuretics (water pills). This medicine can also cause serious skin problems and blood problems in elderly people. Elderly people are also more likely to have a sulfa drug reaction if they take other medicines that cause allergic reactions, such as acetazolamide and methazolamide.
If you have an allergic reaction to sulfa drugs, your doctor can prescribe an antihistamine or another type of medicine to relieve the symptoms. Your doctor can also make changes in your treatment if your condition worsens.
In rare cases, sulfonamide can cause uveitis (eye inflammation). This is most likely to happen with a sulfonamide called trimethoprim. It can also happen with other sulfonamide drugs. If you develop uveitis while taking this medicine, call your doctor.
A sulfonamide reaction usually happens a week or two after you start the medication. It begins with a red, itchy rash that may cover large areas of your body. The rash can spread to other parts of your body and cause high fever and organ problems.[10]

It may be taken by mouth or injected directly into the veins. Your doctor will give you instructions on how to use it. You should not use it if you have a history of an allergic reaction to sulfonamide antibiotics or other drugs that contain sulfhydryl or sulfate groups in their chemical structure.
Sulfonamide antibiotics are usually prescribed in tablet form. They include sulfasalazine (delayed-release tablets) and sulfacetamide (drops and ointment). These medications are also used for other infections, including urinary tract infections, ear infections and parasitic infections such as toxoplasmosis.
Generally, these antibiotics work best when they are given early in the course of infection. If they are not given early, they can develop resistance to the drug and may be less effective.[12]
The sulfonamide antibiotics are used to treat many different types of infections and can be effective for some. They have a bacteriostatic effect by inhibiting bacterial folic acid synthesis.
They are not used to treat most chronic infections, such as septicemia or tuberculosis, because of the risk of developing resistance. Occasionally, sulfonamide antibiotics are combined with other antibiotics to treat certain infections.
This medication is sometimes used to prevent rheumatic fever in children who have allergies to penicillins. It is also used to treat certain inflammatory bowel diseases in adults and children.[13]
Before using this Medicine
