How long do antibiotics stay in your system?

Antibiotics are drugs that inhibit or kill the growth of bacteria. They are prescribed to treat and, less frequently, to prevent bacterial infections.

The effectiveness of Generic Antibiotics is based on selective interaction with pathogen-specific molecular structures. Antibiotics are usually administered:

  • Orally. Taken orally with water.
  • Parenterally. Administered directly into the blood by injection.
  • Topically. Applied to the skin or mucous membranes.


Generic Antibiotics Online is available in the form of tablets, dispersible tablets, capsules, infusion preparations, suspensions and syrups for children, and pellets.

There are also some preparations for topical use, such as creams, ointments, eye drops, eye ointments, ear drops, nasal drops and ointments, and lollipops for sore throats.

Different dosage forms and a wide range of antibiotics are available at medicinesmexicoa certified Mexican pharmacy.

Types of antibiotics

Many antibiotics can be divided into groups based on chemical building blocks.

These include, for example, beta-lactam antibiotics, tetracyclines, quinolones, and macrolides.

Available antibiotics can be purchased at a very favorable price at a Mexican online pharmacy.

It is often forgotten that many antibiotics are of natural origin and have mostly been isolated from fungi or bacteria.

Semi- and fully synthetic derivatives have been derived from natural starting materials.

Antibiotics also differ in their spectrum of action, distinguishing between broad-spectrum and narrow-spectrum antibiotics.

This means an antibiotic can affect several groups of bacteria or one specific group, for example, against Gram-positive, Gram-negative, aerobic, anaerobic, and intracellular bacteria. Broad-spectrum antibiotics are widely available in a Mexican pharmacies.

Mechanism of action of antibiotics

Depending on the type of antibiotics, they stop the reproduction of bacteria or destroy them in different ways.

Typical mechanisms of action include:

  • Inhibition of protein synthesis;
  • Inhibition of cell wall synthesis;
  • Inhibition of DNA replication;
  • Blockade of folic acid metabolism;
  • Damage to macromolecules such as DNA and proteins;
  • Disruption of the cell membrane.

These ways prevent bacteria from developing, allowing the body's immune system to cope with the disease and its aftermath.

Bacteria are constantly producing new resistances. When bacteria multiply, they pass on their genetic information.

By chance, mutations can occur that allow the bacteria to defend themselves.

Because bacteria can develop new, sometimes multiple resistances, new antibiotics must constantly be developed.

What is the right way to take antibiotics?

Antibiotics are usually given over a certain period of therapy (e.g., 3 days, 5 days, 7 days, 10 days, 14 days) or sometimes as a single dose.

Antibiotics are usually taken once a day. But it is essential to follow the doctor's instructions or directions.

Antibiotics should be combined with probiotics to prevent gastrointestinal distress and restore the intestinal microbiome.

If they contain live bacteria, they should be given at regular intervals. An alternative is a yogurt. Special preparations containing probiotics can be purchased quickly at a Mexican pharmacy online.

How long do antibiotics stay in the body?

Antibiotics stay in the body from a few hours to a few days. This time depends on several factors:

the active ingredient of the drug, the duration of therapy, and the individual characteristics of the patient (age, metabolic rate, body weight).

Each antibiotic has its half-life.

The time required for 50% of the drug to be eliminated from the body. As a rule, the drug takes 5-7 half-lives to altogether leave the body.

Using the most well-known antibiotics as examples, we can look at the drug's half-life and final clearance periods.

  • Penicillin- The half-life is about 1.5 hours. The approximate complete clearance of penicillin from the body is 8 hours. It fights various bacterial infections and Staphylococcus, a causative agent of many diseases.
  • Doxycycline- The half-life is approximately 22 hours. Approximate complete drug clearance from the body from 5 to 7 days. It is used to fight sexually transmitted diseases and various infections. You can buy Generic Antibiotics Online containing doxycycline from the best Mexican pharmacy at a very reasonable price.
  • Ciprofloxacin- A powerful antibiotic is used when other medications have been ineffective. The half-life is about 4 hours, and the complete excretion is 22-24 hours.

Side effects of antibiotics

All antibiotics can cause various side effects, depending on the antibiotic itself and the group it belongs to.

The most common and typical possible unwanted effects of antibiotics include:

  • Gastrointestinal disorders include diarrhea, nausea, vomiting, abdominal pain, and loss of appetite.
  • Hypersensitivity reactions (allergic reactions) up to and including anaphylaxis.
  • Candida infections of the mucous membranes, such as vaginal candidiasis and candidiasis stomatitis, and skin rashes.
  • Central nervous disorders such as headaches and dizziness
  • Depending on the active ingredients, numerous other side effects are possible, such as QT interval prolongation, psychiatric disorders, ototoxicity, and liver and kidney dysfunction (selection).


All antibiotics are designed to fight bacterial infections.

To avoid causing antibiotic resistance, taking them only as prescribed by your doctor is essential.

The dosage and duration of therapy must be strictly adhered to; otherwise, serious side effects can occur.
