Doxycycline Online

Doxycycline is a versatile drug. It is an antibiotic that treats bacterial infections therefore it will not work on infections caused by viruses like the common cold or flu. It is a class of antibiotics known as tetracyclines. These antibiotics work by preventing the growth and spread of bacteria.

You need a prescription from a doctor to get Doxycycline, but fortunately you can now meet with a doctor and get Doxycycline prescribed online. Read on to find out more.

What Does Doxycycline Treat?

Some common infections that Doxycycline is used for are:

It is also used to stop the spread of certain infections caused by lice, ticks, mites, infected animals or even contaminated food/water. The medication, which is available online, is also prescribed to treat acne and rosacea.

Doxycycline can additionally be used to treat or prevent anthrax (a serious infection that has been used as a biological weapon). For those who have been exposed to anthrax through air, Doxycycline is used to help them ward off the infection. It can also be used for other serious infections like plague and tularemia. It is used as an alternative drug for those who cannot use penicillin.

How to use Doxycycline

There are several forms of Doxycycline that are available. It can be administered by a capsule, delayed release capsule, tablet, delayed release tablet or liquid. The medication is taken orally and is typically taken once or twice daily, as instructed by a doctor.

The tablet and capsule forms are meant to be swallowed whole, without chewing or crushing of the tablet/capsule. If the user cannot swallow the tablets whole then certain procedures are available. For instance, one can break up the tablets and add the contents to a substance like applesauce (room temperature). The user can then swallow the applesauce without chewing. Those who are taking the liquid form should make sure to shake the bottle before taking the medication. It is recommended that the medication is taken even after you feel well.

Doxycycline must be taken as directed by the doctor, strictly adhering to the dosage as well as the length of medication usage. Terminating the treatment sooner than the time prescribed can result in recurrence of infection. There is also the possibility that ceasing the medication before complete recovery can result in the creation of antibiotic-resistant bacteria. Do not use Doxycycline past the prescribed period.

Side Effects

The possible side effects of Doxycycline are:

  • Upset stomach
  • Nausea and/or vomiting
  • Diarrhea

It is important to contact your doctor if any of these effects worsen or become frequent. Here are some important points to tell your doctor before you begin doxycycline:

  • If you are allergic to doxycycline
  • If you are taking any other medications (prescribed or over the counter)
  • If you are breastfeeding or plan to breastfeed

The prescription of this medication may include some unavoidable side effects that your doctor has already considered. All medications come with the risk of side effects and prescriptions are based on a risk/benefit assessment where your doctor believes that the benefits of using this medication outweigh the risk.

Most people who use Doxycycline do not experience serious side effects. On rare occasion, some patients may experience painful/difficulty swallowing or signs of kidney damage (change in urine color). In the event that this occurs, please seek medical attention immediately.

Doxycycline is classified as a Tetracycline drug and can on occasion cause increased pressure within the skull. Also known as intracranial hypertension, or IH, this side effect has a greater likelihood of occurring in women who are of childbearing age and overweight. Those who have had IH in the past are also susceptible.

In the event that IH develops, the effects will stop once the medication is no longer used. There is a rare chance that permanent blindness may result. Seek medical attention right away if you experience any severe and persistent headaches, vision changes, or persistent nausea/vomiting.

Although rare, doxcycline may cause a severe intestinal condition known as Clostridium Difficile Associated Diarrhea. This is often due to a type of resistant bacteria strain that can manifest during the treatment or after the treatment has ended. It should be noted that any anti-diarrhea products or narcotic pain medication should be avoided because they may exacerbate the situation. Tell your doctor if you experience any persistent diarrhea, abdominal pain, stomach pain or bloody stool.

Lastly, some users may experience an allergic reaction to the drug. This rare occurrence will be accompanied with the following symptoms:

  • Fever
  • Rash
  • Itching/swelling
  • Dizziness
  • Trouble breathing

Please consult a doctor right away if you experience any of the above symptoms.


Inform your doctor of your past medical history and any allergies, especially if you have a medical history of trouble swallowing or esophagus problems. Doxycycline can nullify the effects of immunizations and vaccinations; therefore, it is advisable to not obtain any vaccines while on this medicine unless otherwise told by a doctor.

The medication makes users sensitive to the sun. Therefore it is recommended to avoid the sun, tanning booths or sunlamps. Use sunscreen and protective clothing when outside. This medication is not recommended for pregnant women. Children under 8 years old are much more susceptible to the side effects of Doxycycline. Consult your doctor regarding the use of this medication for minors.
