Doxycycline over the counter


Doxycycline is a versatile antibiotic that falls under the classification of tetracyclines. This medication exhibits a broad spectrum of activity, meaning it is capable of combating a wide range of bacterial infections.

First synthesized in the 1960s, Doxycycline works by inhibiting protein synthesis in bacteria, thereby stalling their growth and multiplication. In other words, it prevents the bacteria from creating proteins essential for their survival. This characteristic makes it a bacteriostatic antibiotic; it does not directly kill bacteria but inhibits their proliferation.

The wide-ranging effectiveness of Doxycycline means it is used in the treatment of many different bacterial infections. These include, but are not limited to, skin infections, urinary tract infections, respiratory infections, certain sexually transmitted infections (STIs), such as chlamydia and gonorrhea, as well as other infections like Lyme disease and anthrax.

Doxycycline Dosage

The dosage and duration of doxycycline prescribed can greatly vary depending on the specific condition being treated, the patient’s age, weight, and overall health status. Always follow the directions provided by your healthcare provider. Here are some general guidelines:

  • For adults with bacterial infections: The usual oral dosage is 100mg to 200mg on the first day, divided into two doses (every 12 hours). Following this, the maintenance dosage is usually 100mg per day.
  • For severe infections: Doses may be increased to up to 200mg per day.
  • For children older than 8 years and weighing less than 45kg: The typical dosage is 2.2mg per kg of body weight given two times on the first day, followed by 2.2mg per kg given once per day. The total daily dosage should not exceed 200mg.
  • For children older than 8 years and weighing 45 kg or more: The adult dosage is typically used.
  • For prevention of malaria: The usual dose is 100mg per day, starting 1-2 days before travel to the area where malaria transmission occurs. It’s continued daily while in the malarial area and for 4 weeks after leaving.
  • For the treatment of acne: The usual dose is 100mg daily.

It’s important to take doxycycline with a full glass of water to avoid irritation of the esophagus. The medication can be taken with food if it causes stomach upset, but avoid taking it at the same time as any calcium or iron supplements, antacids, or dairy products as these can interfere with absorption.

Remember that the above dosages are general recommendations and the exact dosage may vary. Always adhere to the prescribed dosage from your healthcare provider. Do not stop taking the medication even if you feel better until the entire course of treatment is completed, as stopping early may lead to a return of the infection or development of antibiotic resistance.

If you miss a dose, take it as soon as you remember. If it’s near the time of your next dose, skip the missed dose and continue with your regular dosing schedule. Do not double up on doses to catch up.

In case of a suspected overdose, seek immediate medical attention. Symptoms may include nausea, vomiting, and diarrhea.

As always, it’s crucial to communicate with your healthcare provider about your treatment, and never hesitate to ask questions if you have any doubts or concerns.

Side effects

Like any medication, doxycycline can cause side effects. Not everyone will experience these, but it’s important to be aware of what might occur. Common side effects include:

  • Nausea
  • Vomiting
  • Diarrhea
  • Loss of appetite
  • Sensitivity to sunlight (photosensitivity)

More serious side effects, although less common, can include:

  • Severe stomach or abdominal pain
  • Difficulty swallowing
  • Sore or irritated throat
  • Dark or decreased urine
  • Vision changes

If you experience any serious side effects or your symptoms worsen, immediately seek medical attention.


  • Allergies: Inform your healthcare provider if you have any allergies, particularly to tetracycline antibiotics or doxycycline itself.
  • Medical history: Disclose your medical history to your healthcare provider, particularly if you have had liver disease, kidney disease, difficulty swallowing, esophagus problems (like hiatal hernia or reflux/heartburn).
  • Pregnancy and breastfeeding: Doxycycline may harm an unborn baby or cause permanent tooth discoloration later in life. Discuss with your healthcare provider if you are pregnant, plan to become pregnant, or are breastfeeding.
  • Children: This medication is not recommended for use in children younger than 8 years unless absolutely necessary due to the risk of tooth discoloration.
  • Sun sensitivity: Doxycycline can make you more susceptible to sunburn. Limit your time in the sun and avoid tanning booths and sunlamps. Use sunscreen and wear protective clothing when outdoors.

Doxycycline Storage

Doxycycline should be stored at room temperature, typically between 20°C to 25°C (68°F to 77°F), away from light and moisture. It should not be stored in the bathroom. Keep all medications out of the reach of children and pets.

Do not flush medications down the toilet or pour them into a drain unless instructed to do so. Properly discard this product when it is expired or no longer needed. Consult your pharmacist or local waste disposal company for more details about how to safely discard your product.

Remember, it’s crucial to maintain open lines of communication with your healthcare provider throughout your course of treatment. This allows them to provide the best care possible, and address any concerns you may have.

Interaction with other medications

Doxycycline can interact with a number of different medications, which may affect how it works or increase your risk for serious side effects. Some examples include:

  • Retinoids: Taken orally for skin conditions, these can increase intracranial pressure, leading to severe headaches, blurred vision, and other symptoms.
  • Antacids, iron, and calcium supplements: These can bind with doxycycline in the stomach and reduce its absorption and effectiveness. Doxycycline should be taken 2-3 hours before or after taking these medications.
  • Warfarin: Doxycycline can increase the effect of warfarin, a blood thinner, potentially leading to an increased risk of bleeding.
  • Birth control pills: Some evidence suggests that doxycycline might reduce the effectiveness of birth control pills. Discuss with your healthcare provider if you should use additional contraceptive methods while on doxycycline.
  • Other antibiotics: Certain antibiotics can interfere with the effectiveness of doxycycline.
  • Barbiturates, carbamazepine, and phenytoin: These medications may decrease the half-life of doxycycline, thereby reducing its effectiveness.

This is not a complete list and other interactions may exist. Always inform your healthcare provider and pharmacist about all the medications you are currently taking, including prescription drugs, over-the-counter drugs, and herbal products. This way, they can monitor for interactions and manage them appropriately.
