How to use

Here are some general guidelines on how to use Doxycycline:

  1. Take with water: Swallow the tablet or capsule whole with a full glass of water. Do not crush, chew, or break the tablet or capsule.
  2. Take with food or milk: To reduce the risk of stomach upset, take drug with a meal or a glass of milk. However, some forms of Doxycycline may need to be taken on an empty stomach for optimal absorption.
  3. Do not take with certain substances: Avoid taking this antibiotic with antacids, calcium supplements, iron supplements, or dairy products. These substances can interfere with the absorption of Doxycycline. If needed, separate the timing of taking capsules and these substances by a few hours.
  4. Follow the prescribed dosage: Do not alter the dosage or stop taking the medication without their guidance, even if you start feeling better.
  5. Finish the full course: Complete the full course of Doxycycline treatment, even if your symptoms improve before the medication is finished. Stopping the medication too soon may allow the infection to return or develop antibiotic resistance.
  6. Avoid exposure to sunlight: Antibiotic can make your skin more sensitive to sunlight and increase the risk of sunburn. Avoid prolonged sun exposure and use sunscreen with a high sun protection factor (SPF) when outdoors.


The dosage of Doxycycline can vary depending on the specific condition being treated, the severity of the infection, and individual factors such as age and weight. Here are some general guidelines for the dosage:

  1. Adults: The typical adult dosage for most infections is 100 milligrams (mg) to 200 mg of Doxycycline initially, followed by a maintenance dose of 100 mg to be taken once or twice daily. The exact dosage and duration of treatment may vary depending on the infection being treated.
  2. Children: The dosage for children is based on their weight.
  3. Timing of doses: The total daily dosage of Doxycycline is often divided into two or more doses taken throughout the day. Follow the prescribed dosing schedule and try to take the medication at evenly spaced intervals.
  4. Special considerations: In certain situations, such as the treatment of severe infections or prevention of malaria, higher doses or different dosing regimens may be prescribed.

It is important to note that the information provided here is a general guideline and may not be applicable to every individual or condition. Dosage adjustments and specific instructions may be necessary based on your unique circumstances.

Side effects

Doxycycline, like other medications, may cause side effects in some individuals. While not everyone experiences side effects, it is important to be aware of potential adverse reactions. Common side effects may include:

  1. Gastrointestinal effects: Nausea, vomiting, diarrhea, stomach upset, and abdominal pain are among the most commonly reported side effects. Taking Doxycycline with food or a glass of milk can help reduce these symptoms.
  2. Skin sensitivity: Antibiotic can make your skin more sensitive to sunlight, leading to an increased risk of sunburn. It is advisable to avoid prolonged sun exposure, wear protective clothing, and use sunscreen with a high sun protection factor (SPF) when outdoors.
  3. Yeast infections: Doxycycline may disrupt the natural balance of bacteria in the body, which can lead to the overgrowth of yeast and result in vaginal yeast infections or oral thrush (white patches in the mouth).
  4. Effects on the liver: Rarely, Doxycycline may cause liver problems, such as elevated liver enzymes. If you experience symptoms such as yellowing of the skin or eyes (jaundice), dark urine, or persistent abdominal pain, seek medical attention.
  5. Allergic reactions: In some cases, individuals may experience allergic reactions to Doxycycline. Signs of an allergic reaction may include rash, itching, swelling (especially of the face, tongue, or throat), severe dizziness, or difficulty breathing. Seek immediate medical attention if you experience any of these symptoms.
  6. Other potential side effects: Less common side effects may include headache, dizziness, blurred vision, difficulty swallowing, or changes in the blood cell count.

It is important to remember that these are not all the possible side effects of Doxycycline. Different individuals may react differently to the medication.


When it comes to storing Doxycycline, it is essential to follow the recommended guidelines to maintain its effectiveness and ensure your safety. Here are some general instructions for storing:

  1. Temperature: Store capsules at room temperature, ideally between 68°F (20°C) and 77°F (25°C). Avoid extreme temperature fluctuations and keep it away from direct heat sources, such as radiators or direct sunlight.
  2. Moisture: Protect Doxycycline from moisture and humidity. Avoid storing it in the bathroom, where humidity levels are typically high. A dry place, such as a medicine cabinet or a cupboard away from moisture, is preferable.
  3. Packaging: Keep capsules in its original packaging, such as the bottle or blister pack, until you are ready to take it. This helps protect the medication from light, moisture, and air exposure.
  4. Childproof container: Store drug in a childproof container or a secure place out of reach of children and pets. This will prevent accidental ingestion and ensure their safety.
  5. Discard expired medication: Check the expiration date of Doxycycline before use. If it has expired, dispose of it properly according to local regulations. Expired medication may not be effective and can potentially be harmful.

Always read the product label, packaging, or information leaflet provided with your Doxycycline for any specific storage instructions.


An overdose of Doxycycline can potentially be serious and may require immediate medical attention. If you suspect an overdose or have accidentally taken more medicament than prescribed, here are some steps to consider:

  1. Seek medical help: Contact your local emergency services right away. They will be able to provide guidance and instructions based on your specific situation.
  2. Provide necessary information: When seeking medical help, provide details about the amount of Doxycycline you have taken, the time of ingestion, and any symptoms you may be experiencing.
  3. Do not induce vomiting: Vomiting may not effectively remove the medication from your system and can potentially cause additional complications.
  4. Follow medical advice: Follow the instructions provided by medical professionals. They may recommend further evaluation, monitoring, or treatment based on the severity of the overdose and your symptoms.

It is important to remember that an overdose of Doxycycline can have different effects on individuals, and the appropriate actions may vary depending on the specific circumstances. Therefore, seeking immediate medical attention is crucial to ensure your safety and receive appropriate care.

  2. Set a reminder: To help remember taking your doses on time, consider setting a reminder on your phone, using a pill organizer, or incorporating the medication schedule into your daily routine.
