Tetracycline FAQs
What is Tetracycline?
Tetracycline is an antibiotic that stops the growth of bacteria and treats various bacterial and sexually transmitted infections (STIs), such as chlamydia.
Tetracycline is approved by the FDA.
At SpeedyHealth, our doctors are able to prescribe Tetracycline in 500mg capsules after you complete a consultation.
How does Tetracycline work?
Tetracycline is an antibiotic that stops bacteria from growing by blocking their ability to make essential proteins. They do this by attaching to a part of the bacteria's protein-making machinery. This prevents the bacteria from multiplying and helps your immune system get rid of the infection effectively.
It is often used to treat conditions like acne and urinary tract infections (UTIs) and can also treat some sexually transmitted infections (STIs).
Tetracyclines are effective against many types of bacteria, including both gram-negative and gram-positive ones. These are two forms of bacteria that differ based on their cell wall structure.
What are the benefits of taking Tetracycline?
There are many benefits of taking this medicine to treat illnesses, for example:
- It can treat a wide variety of infections, including respiratory tract infections, skin infections and other STIs.
- It can be a good option for people allergic to penicillin or related antibiotics.
- It is an easy-to-take oral medication.
How effective is Tetracycline?
Tetracycline is effective in treating both men and women with chlamydia.
Randomized controlled trials that compared Tetracycline to Rosaramicin found that 97% of patients assessed at a follow-up visit 1 week or more after completing treatment with Tetracycline tested negative for chlamydia.
How to use
How and when should I take Tetracycline?
At SpeedyHealth, Tetracycline is available as 500mg capsules. The dose to treat chlamydia is one 500mg capsule taken by mouth four times a day for seven days.
To take this medicine correctly, make sure to swallow the capsules whole with a glass of water. If possible, this medicine should be taken on an empty stomach as certain foods and dairy products can interfere with the absorption.
Make sure to sit or stand upright for at least 30 minutes after taking this medicine to prevent throat irritation.
What if I miss a dose?
If you forget to take a dose, take the missed dose as soon as you remember. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
How long does Tetracycline take to work?
Tetracycline begins to work as soon as you take your first dose. It typically clears up infections in about 7 days. However, if your infection worsens or symptoms don’t resolve, seek medical attention.
How long should I take Tetracycline for?
A course of Tetracycline is usually taken for 7 days to completely cure chlamydia. It is important to complete the entire course of this antibiotic, even if you start to feel better. If you don’t complete the course, the infection may not be properly treated or may return.

Abstain from sexual intercourse while you have the infection and when taking treatment.
Maintain monogamy
Have sex with only one uninfected partner who only has sex with you.
Get regularly tested
Get tested for STIs regularly if you're sexually active.
If you are diagnosed with chlamydia, you should inform all your recent sexual partners so they can also get tested and treated if needed.

Speedy health was fast
Speedy health was fast, safe and efficient. I didn't have to drive 35 miles into town to wait at the doctor's office for 2 hours to have them write me prescription. Then wait another 2 hours to have the prescription filled. It came right to my mailbox. I highly recommended speedy health.
