The brown and white, oblong capsule with the imprint 'par 727' is a 100 mg dose of Doxycycline Monohydrate. As a broad-spectrum antibiotic from the tetracycline class, it is used to inhibit the growth and spread of bacteria by disrupting their ability to produce necessary proteins. This makes it a powerful tool for fighting a range of bacterial illnesses, but it is ineffective against viral infections like the common cold or flu. This prescription-only medication requires careful administration and adherence to a healthcare provider’s instructions.
Medical Uses for Doxycycline Monohydrate (par 727)
Doxycycline is a versatile medication with many applications beyond just general infections. Its ability to combat both Gram-positive and Gram-negative bacteria allows it to treat conditions in different parts of the body.
- Skin Conditions: It is a common treatment for severe acne and rosacea. For acne, it reduces the bacteria infecting pores, while for rosacea, it decreases inflammation.
- Respiratory Infections: It can be used to treat lung infections such as pneumonia.
- Sexually Transmitted Infections (STIs): Doxycycline is effective against chlamydia, syphilis, gonorrhea, and other STIs.
- Preventative Treatment: It is prescribed to prevent malaria in travelers and for post-exposure prophylaxis for conditions like anthrax.
- Other Infections: The medication also addresses a variety of other infections, including those of the urinary tract, gastrointestinal tract, and those caused by ticks or mites, such as Rocky Mountain spotted fever.
Important Precautions and Potential Side Effects
Before taking par 727, patients should inform their doctor of any allergies and all other medications they are currently taking, including vitamins and herbal supplements. Several precautions are necessary to ensure safe use.
- Photosensitivity: This antibiotic can make your skin more sensitive to sunlight, increasing the risk of severe sunburn. Patients should avoid prolonged sun exposure, wear protective clothing, and use sunscreen.
- Drug Interactions: Certain supplements and medications can reduce its effectiveness. Antacids containing aluminum, calcium, or magnesium, as well as iron products and vitamins with iron, should be taken at least 1–2 hours before or after the doxycycline dose. Doxycycline can also reduce the effectiveness of hormonal contraceptives, so alternative birth control methods should be considered.
- Esophageal Irritation: To prevent damage to the esophagus, take the pill with a full glass of water and avoid lying down for at least 30 minutes after.
- Discoloration of Teeth: Due to the risk of permanent tooth discoloration, doxycycline is generally not recommended for children under 8 years of age or during pregnancy.
- Antibiotic Resistance: Using antibiotics inappropriately for viral infections or stopping the course early can contribute to antibiotic resistance.
