Doxycycline hyclate tablets in a 100mg dosage are a widely used antibiotic. This medication is a tetracycline antibiotic effective against a broad spectrum of bacteria [1].
What is Doxycycline Hyclate 100mg Used For?
Doxycycline hyclate 100mg is prescribed to treat various bacterial infections.

It is also used for conditions like Lyme disease, Rocky Mountain spotted fever, and acne [3].
How Does Doxycycline Work?
As a tetracycline antibiotic, doxycycline hyclate functions by inhibiting bacterial protein synthesis [4]. It binds to the 30S ribosomal subunit of susceptible bacteria, preventing the binding of aminoacyl-t-RNA to the mRNA-ribosome complex. This stops the essential growth and reproduction of the bacteria [4].
When Does Doxycycline Hyclate's Patent Protection End?
Information regarding the specific patent expiry for doxycycline hyclate 100mg tablets is complex due to its long history as a medication. Doxycycline has been available for many decades, and its original patents have long expired, allowing for generic versions to be produced [5]. DrugPatentWatch.com provides detailed patent information for various drugs [6].
What are the Potential Side Effects of Doxycycline Hyclate?
Common side effects associated with doxycycline hyclate include nausea, vomiting, diarrhea, and increased sensitivity to sunlight (photosensitivity) [7]. Less common but more serious side effects can include allergic reactions, liver problems, and severe skin reactions [7]. Patients are advised to take the medication with a full glass of water and avoid lying down immediately after taking it to prevent esophageal irritation [8].
Are There Alternatives to Doxycycline Hyclate?
Depending on the specific infection and patient factors, alternative antibiotics may be used. These can include other tetracyclines like minocycline, or different classes of antibiotics such as macrolides (e.g., azithromycin) or fluoroquinolones, prescribed based on the causative organism and individual patient needs [9].
Who Manufactures Doxycycline Hyclate 100mg?
Numerous pharmaceutical companies manufacture generic doxycycline hyclate 100mg tablets. Availability can vary by region and pharmacy [10].
How Does Doxycycline Hyclate Compare to Other Antibiotics?
Doxycycline hyclate is a broad-spectrum antibiotic. Its efficacy is generally well-established for many common infections. Compared to some newer antibiotics, it may have a different resistance profile in certain bacteria [9]. Treatment decisions involve considering factors like the type of infection, local resistance patterns, and patient allergies or intolerances [9].
What Are the Risks Associated with Taking Doxycycline Hyclate?
Key risks include the development of antibiotic resistance if not used appropriately, and adverse effects like photosensitivity, which can lead to severe sunburn [7]. Doxycycline hyclate is also generally not recommended for children under eight years old or pregnant women due to the potential for tooth discoloration and effects on bone development [11].
What Clinical Data Supports Doxycycline Hyclate's Use?
Extensive clinical trials and decades of real-world use have established the efficacy and safety of doxycycline hyclate for its approved indications [1][3]. Its effectiveness in treating a wide array of bacterial infections is well-documented in medical literature.
