Doxycycline is a broad-spectrum antibiotic medication that is commonly prescribed to treat various bacterial infections. It belongs to the class of drugs known as tetracyclines.

Antibiotic works by inhibiting the growth and spread of bacteria. It does this by interfering with the protein synthesis process in the bacterial cells, ultimately leading to their destruction.

Pharmaceutical product is used to treat a wide range of infections, including respiratory tract infections, urinary tract infections, skin and soft tissue infections, eye infections, sexually transmitted infections, and certain types of tick-borne illnesses like Lyme disease. It can also be prescribed as a preventive measure for certain infections, such as malaria.

This medication is available in different forms, including tablets, capsules, and oral suspensions.

The use of Doxycycline (Vibramycin) also reduces the action of bacteria

Uses of Doxycycline

Here are some common uses of Doxycycline:

  1. Bacterial Infections: Medicine is effective against a wide range of bacterial infections. It is commonly prescribed to treat respiratory tract infections, such as pneumonia and bronchitis, as well as urinary tract infections, sinus infections, and skin infections like acne, cellulitis, and folliculitis.
  2. Sexually Transmitted Infections (STIs): Doxycycline is used to treat certain sexually transmitted infections, including chlamydia, gonorrhea, and syphilis. It is often prescribed as a single dose or taken over a course of several days.
  3. Malaria Prevention and Treatment: Doxycycline is used as a preventive measure against malaria when traveling to areas where the disease is prevalent. It is also used for the treatment of malaria in combination with other antimalarial medications.
  4. Lyme Disease: Doxycycline is the first-line treatment for early-stage Lyme disease. It is effective in combating the bacterial infection caused by tick bites and is usually taken for a period of 10 to 21 days, depending on the stage and severity of the disease.
  5. Rosacea: Antibiotic is sometimes prescribed to manage the symptoms of rosacea, a chronic inflammatory skin condition. It can help reduce redness, inflammation, and the formation of papules and pustules associated with rosacea.
  6. Acne: Drug is often used as an oral antibiotic treatment for moderate to severe acne. It helps control the growth of bacteria on the skin and reduces inflammation, leading to improved acne symptoms.


Some general guidelines for the typical dosages of Doxycycline for certain conditions:

  1. Respiratory Infections: For respiratory tract infections, such as pneumonia or bronchitis, the typical adult dosage is 100 mg to 200 mg once daily or divided into two doses.
  2. Skin Infections: For skin infections, such as acne or cellulitis, the usual adult dosage is 50 mg to 100 mg twice daily.
  3. Sexually Transmitted Infections (STIs): For the treatment of sexually transmitted infections like chlamydia or gonorrhea, a single dose of 100 mg to 200 mg of Doxycycline may be prescribed.
  4. Lyme Disease: The recommended dosage for treating Lyme disease in adults is 100 mg twice daily for 10 to 21 days, depending on the stage and severity of the infection.

How to Take

Here are some general guidelines for taking Doxycycline:

  1. Timing: Take medicine exactly as prescribed. It is usually taken orally with a full glass of water. Some formulations should be taken on an empty stomach, while others can be taken with food.
  2. Dosage: Take the prescribed dosage of Doxycycline. The dosage can vary depending on the condition being treated, the severity of the infection, and other factors. It's important to take the full course of treatment as prescribed, even if you start feeling better before completing it.
  3. Interactions: Be cautious about potential drug interactions. Certain medications, such as antacids, iron supplements, or dairy products, can interfere with the absorption of Doxycycline.
  4. Duration: Complete the full course of treatment. Even if your symptoms improve, it's important to continue taking Doxycycline for the entire prescribed duration. Stopping the medication prematurely can result in incomplete treatment and may lead to the return of the infection or antibiotic resistance.
  5. Sun Protection: Doxycycline can make your skin more sensitive to sunlight, increasing the risk of sunburn. Take precautions such as using sunscreen, wearing protective clothing, and avoiding prolonged exposure to direct sunlight or tanning beds while taking doxycycline.

Side Effects of Doxycycline

Pharmaceutical product can have side effects. Not everyone will experience these side effects, and their severity can vary. Here are some common side effects:

  1. Gastrointestinal Effects: Antibiotic can cause gastrointestinal side effects such as nausea, vomiting, diarrhea, and abdominal pain. Taking the medication with food or a full glass of water can help minimize these effects.
  2. Photosensitivity: Medicine can make your skin more sensitive to sunlight, leading to an increased risk of sunburn. It's important to take precautions by using sunscreen, wearing protective clothing, and avoiding prolonged sun exposure while on doxycycline.
  3. Yeast Infections: In some cases, Doxycycline may disrupt the natural balance of microorganisms in the body, leading to an overgrowth of yeast and resulting in a yeast infection, such as oral or vaginal thrush.
  4. Allergic Reactions: Although rare, some individuals may experience an allergic reaction to Doxycycline. Symptoms may include rash, itching, swelling, dizziness, or difficulty breathing. Seek immediate medical attention if you develop signs of an allergic reaction.
  5. Tooth and Bone Development (in children): Drug can affect the development of teeth and bones in children under the age of 8. It is generally not prescribed to this age group unless the benefits outweigh the potential risks.
  6. Other Potential Side Effects: Other possible side effects of doxycycline include headache, dizziness, skin discoloration, vaginal itching or discharge, and changes in taste.

It's important to note that this list is not exhaustive, and other side effects may occur.


Doxycycline can interact with certain medications, supplements, and substances, potentially affecting their effectiveness or increasing the risk of side effects. Here are some notable interactions:

  1. Antacids, Calcium, Iron, and Magnesium Supplements: Avoid taking doxycycline with antacids, calcium supplements, iron supplements, or magnesium-containing products. These substances can bind to Doxycycline in the stomach, preventing its proper absorption into the bloodstream. If you need to take these supplements, allow a time gap of at least 2 hours before or after taking doxycycline.
  2. Oral Contraceptives: Medicine can reduce the effectiveness of hormonal contraceptives, such as birth control pills, patches, or injections. It is recommended to use additional or alternative methods of contraception while taking Doxycycline and for some time after discontinuing the medication.
  3. Blood Thinners (Anticoagulants): There have been rare reports of increased bleeding tendencies in patients taking Doxycycline and anticoagulant medications like warfarin. Regular monitoring of blood clotting parameters may be necessary if these medications are used concomitantly.
  4. Methotrexate: Taking methotrexate and Doxycycline together may increase the risk of methotrexate toxicity. Close monitoring of methotrexate levels and potential dose adjustments may be required when using these medications concurrently.
  5. Other Antibiotics: Combining Doxycycline with certain other antibiotics, such as penicillins or cephalosporins, may interfere with their effectiveness.
  6. Alcohol: While there is no direct interaction between doxycycline and alcohol, it is generally recommended to avoid consuming alcohol while on any antibiotic treatment. Alcohol can impair the immune system and may interfere with the body's ability to fight infections effectively.


While Doxycycline is generally safe and effective when used as prescribed, there are certain warnings and precautions to be aware of. Here are some important warnings:

Allergic Reactions: Some individuals may be allergic to doxycycline or other tetracycline antibiotics. Seek immediate medical attention if you develop signs of an allergic reaction, such as rash, itching, swelling, dizziness, or difficulty breathing.

Pregnancy and Breastfeeding: Antibiotic can harm the developing fetus and affect tooth and bone development in infants. It is generally not recommended for use during pregnancy, especially during the second and third trimesters. Additionally, Doxycycline can pass into breast milk and may harm a nursing baby.

Children and Adolescents: Medicament may affect the growth of bones and teeth in children and adolescents. It should generally be avoided in children under the age of 8, unless there are no suitable alternatives and the benefits outweigh the risks. If doxycycline is prescribed to a child, careful monitoring and appropriate dosage adjustments may be necessary.

Photosensitivity: Doxycycline can make your skin more sensitive to sunlight, increasing the risk of sunburn. Take precautions such as using sunscreen, wearing protective clothing, and avoiding prolonged sun exposure or tanning beds while on Doxycycline.

Antibiotic Resistance: Misuse or overuse of antibiotics can contribute to the development of antibiotic-resistant bacteria. It's important to take doxycycline as prescribed, complete the full course of treatment, and avoid using it for conditions not specifically indicated.

Doxycycline and Alcohol

When taking any medication, it's important to understand its potential interactions with alcohol.

Consuming alcohol while taking Doxycycline is generally not recommended. Alcohol can interfere with the effectiveness of the medication and may increase the risk of certain side effects. Here are a few reasons why it's best to avoid alcohol while on Doxycycline:

  1. Reduced effectiveness: Alcohol can impair the absorption and metabolism of Doxycycline in the body, potentially reducing its effectiveness in treating the infection.
  2. Increased side effects: Both doxycycline and alcohol can cause similar side effects such as gastrointestinal upset, nausea, vomiting, and dizziness. When taken together, these side effects may be intensified and become more severe.
  3. Liver stress: Both Doxycycline and alcohol can put stress on the liver. Combining the two may increase the strain on the liver and potentially lead to liver damage or other complications.
  4. Treatment duration: Antibiotic is often prescribed for a specific period, usually a few days or weeks. It's important to complete the full course of treatment. Alcohol consumption can interfere with medication adherence and potentially hinder the effectiveness of the treatment.
