Doxycycline 100 Mg Tablets

Doxycycline is a broad-spectrum antibiotic belonging to the tetracycline class of medications. It is used to treat a wide range of bacterial infections and is also used for other medical purposes, such as preventing malaria.

How it Works
Doxycycline works by inhibiting bacterial protein synthesis. It binds to the 30S ribosomal subunit of bacteria, which prevents the attachment of aminoacyl-tRNA. This action halts the addition of new amino acids to the growing protein chain, effectively stopping the bacteria from multiplying. Because it stops growth rather than directly killing the bacteria, it is considered a "bacteriostatic" agent. The body's immune system can then more easily fight off the remaining bacteria.

Common Uses
Doxycycline is prescribed for various conditions, including:

Bacterial Infections: It is effective against respiratory tract infections (like bacterial pneumonia and bronchitis), urinary tract infections, and skin infections (such as severe acne).

Sexually Transmitted Infections (STIs): It is used to treat chlamydia, syphilis, and gonorrhea.

Other Infections: Doxycycline is also used to treat Lyme disease, Rocky Mountain spotted fever, and cholera.

Skin Conditions: It is used to manage rosacea, a skin condition that causes redness and pimples.

Malaria Prevention: It is often prescribed to travelers to prevent malaria.

Anthrax: It is used to treat or prevent anthrax infection after possible exposure.

Side Effects and Warnings
Like all medications, doxycycline can cause side effects. Common ones include:

Gastrointestinal issues: Nausea, vomiting, and diarrhea. Taking the medication with food can help, but it's important to avoid taking it with dairy products or antacids, as they can interfere with absorption.


Photosensitivity: Doxycycline can make your skin more sensitive to the sun, increasing the risk of sunburn. It's important to use sunscreen and wear protective clothing when outdoors.


Esophagitis: The pills can irritate the throat and esophagus, especially if they are not swallowed with a full glass of water and while in an upright position. It is recommended to remain upright for at least 30 minutes after taking the medication.

Yeast infections: As an antibiotic, it can disrupt the natural balance of bacteria in the body, leading to yeast infections.
