What is 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

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.

What Are The Side Effects Of Doxycycline?

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.

Why Choose Doxycycline?

Doxycycline is not only an affordable option for those with chlamydia, but it is also extremely effective. Most people report their symptoms completely disappear after 5 days of treatment. Additionally, doxycycline appears to be an appealing choice compared with other available antibiotics for treating and managing a handful of STIs.

Besides treating certain sorts of infections, chlamydia is one of the leading causes of curable blindness. This comes with separate long-term and short-term health issues that include hereditary harm to sperm, resulting in infertility and pelvic inflammatory diseases in women.

Considering the restored interest in doxycycline in STI treatment, it is important to note that doxycycline in a standard dose is relatively better for appearance - due to it being able to treat acne - and chlamydia.

Can I Buy Doxycycline Capsules Online?

You will be prescribed doxycycline for chlamydia treatment in packs of 100mg tablets in the following amounts:

  • 7 Days (14 capsules)
  • 14 Days (28 capsules)

What Are The Advantages of Taking Doxycycline?

Doxycycline is one of the most effective options available for treating chlamydia. In addition to chlamydia, it treats eye infections or genitourinary infections prompted by certain chlamydia species. It may even be used for treating severe acne. It is one of the best alternatives for penicillin when penicillin is contraindicated. Besides, doxycycline has zero to no psychological connotations, and it is one of the most affordable forms of curing chlamydia.

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.

How to Prevent the Further Spread of Chlamydia?

While treating the sexually transmitted disease with Doxycycline, it is essential to avoid its spread. In order to do so, follow the given instructions:

  • Avoid sexual contact with individuals whilst taking Doxycycline.
  • Inform your sexual partner/partners when you have tested positive and advise them to get tested. They should receive treatment at the same time as you.
  • Repeat your test three months after treatment with Doxycycline if you are under 25 years old.

Note that chlamydia tests can take about 3 to 5 weeks to turn out as negatives even after successfully treating the sexually transmitted disease.

In addition to this, avoid repeating chlamydia treatment with Doxycycline within four months of the initial treatment unless a healthcare provider advises you to do so.

What are some alternative antibiotic treatments for chlamydia?

If, for some reason, Doxycycline is unsuitable for you, you can turn to alternative antibiotic treatments for treating chlamydia. A popular alternative is Azithromycin 1 gm – or 500 mg twice daily. Similarly, you can take courses of azithromycin for two days and ofloxacin for seven days as they work best for individuals with chlamydia who can not take Doxycycline. However, keep in mind that your primary healthcare provider or a specialist sexual health clinic must prescribe these.

Can I buy Doxycycline over the counter?

No. Doxycycline is a prescription-only antibiotic. In the UK, all antibiotics require a prescription. Therefore, it is important to avoid over-the-counter Doxycycline as it could be potentially harmful. However, you can fill out a quick online consultation on our website in order to apply for a prescription. The consultation will consist of a questionnaire which our team of experts will evaluate to help determine whether you require the medication or not. Once approved, we will issue you a prescription, which will allow you to purchase Doxycycline.

Always read the patient information leaflet before starting your treatment. The patient information can be found here.
