About Doxycycline

Doxycycline is a second-generation tetracycline. It is incredibly effective in fighting bacterial infections found in various parts of the body. It has been available worldwide for nearly half a century. Doxycycline, in essence, is a tetracycline antibiotic. It can not cure viral infections. As it is an antibacterial drug, it is most commonly used to treat as well as manage bacterial and parasitic infections.

Bacterial infections include STIs (sexually transmitted infections)  like urinary tract infections, gonorrhoea, chlamydia, syphilis and others. In addition to this, infections can also be treated using doxycycline capsules, including intestinal infections, respiratory infections, eye infections, and more.

However, before using this medication, it is crucial to consult your doctor to ensure you are not allergic to doxycycline or any other kind of tetracycline antibiotic. If you and your partner both experience the same symptoms of the infection, you both must take the treatment as soon as possible.

How effective Is Doxycycline in treating chlamydia?

While doxycycline is quite effective in treating as well as managing several infections, it is known as one of the most efficacious medications to take to treat chlamydia.

Certain medicines and supplements influence the effectiveness of doxycycline. Therefore, it is best to take the capsules with food and avoid any other medication unless your doctor advises you otherwise. Medication to avoid includes iron supplements, multivitamins, supplements containing calcium, antacids, or even laxatives within two to three hours before or after taking doxycycline. Any medication or supplements that contain calcium, magnesium, aluminium and, lastly, iron influence the effectiveness of doxycycline.

What Does Doxycycline Contain?

Each doxycycline capsule contains either a 50mg or 100mg base of doxycycline. Other ingredients present in doxycycline include:

  • Gelatin
  • Magnesium Stearate
  • Shellac Glaze
  • Sodium Lauryl Sulfate
  • Starch

How does Doxycycline work?

As mentioned above, doxycycline is an antibiotic used to treat a wide array of infections. Doxycycline works by repressing bacterial protein synthesis by fastening to a ribosomal subunit. This further prevents amino acids from staying linked together. Furthermore, without any proteins available, bacteria in your body will be unable to function. Note that doxycycline is bacteriostatic. In simple words, it prevents the bacteria from reproducing but does not necessarily eradicate them.


What dose should I choose?

It is advised to take doxycycline regularly since it is usually intended for short-term use. You can easily contact your general practitioner or our specialists at Click Pharmacy through the website, email, or telephone for guidance. Heed the consultations of the experts so you become aware of the ideal dose for your treatment.

Ordinarily, for people with unchallenging genital chlamydia, it is suggested to take doxycycline 100 mg by oral means twice a day for 7 days. However, the dosage depends on your condition.

How should I take Doxycycline?

It is necessary to take doxycycline at the same hour every day for as long as prescribed. The quantity should not be increased or decreased unless advised otherwise. For an STI like chlamydia, it is essential to understand and follow the treatment plan to the dot. It is to make sure that the infection is entirely eradicated and you are protected as well.

Once again, you should always follow your doctor’s advice before moving forward with a course of treatment. However, in general, the capsule should be taken twice a day. It is recommended that the capsules are taken while standing. It is better to take the capsule with food and water to avoid nausea. Also, if you forget to take a dose, try to take it as soon as possible. And do not double the dosage if you miss a dose.

Side effects

Doxycycline does not have any common severe side effects. It is highly unusual to experience side effects when you are on doxycycline; however, some patients may experience nausea, vomiting or diarrhoea. Furthermore, you can experience a loss of appetite, an itchy rectum or vagina, a sore throat and swollen tongue, as well as dry mouth. You may even experience some anxiety and back pain.

In some cases, side effects may include sensitivity to sunlight. Precautionary measures must be taken, such as wearing sunscreen (SPF 30 or higher) on all exposed parts of your body when you are outside, as sunburns might occur. Try wearing long-sleeved clothing as well as hats and sunglasses when you are taking this medication. Avoid tanning beds.

It is advised to contact your general practitioner immediately and to seek medical aid if you experience:

  • Excruciating stomach pain, diarrhoea that contains water or is bloody.
  • Irritation in the throat, hard time swallowing.
  • Pain in throat, abnormal heart rhythm, feeling shortness of breath.
  • Decreased or no urination.
  • Low white blood cell counts - fever, chilliness, swollen organs, body pains, dizziness, pale skin, bruising or bleeding.
  • Constant headaches, ringing in your ears, queasiness, vision problems, discomfort behind your eyes.
  • Complete loss of appetite, pain in the upper stomach (that might spread to your back), fatigue, vomiting, racing heart rate, darkened urine, jaundice (yellowing of the skin or eyes or gums).

Get emergency medical help if you experience any symptoms of an allergic reaction to doxycycline. Symptoms may include hives, laboured breathing, increasing swelling in your face or throat or a severe skin reaction (fever, raw throat, burning in your eyes, pain on skin, red or purplish skin rash that spreads around and causes painful blistering and peeling).

Note: Do not take doxycycline if you are pregnant or lactating. It is not recommended for children under the age of eight.
