Tetracycline by AA Pharma
How does this medication work? What will it do for me?
Tetracycline belongs to the class of medications called antibiotics. It is used to treat certain types of infections that are caused by bacteria (antibiotics are not useful for viruses like the ones that cause the common cold).
Tetracycline is most commonly used to treat infections of the skin (including acne), Lyme disease, and certain sexually transmitted infections.

For 2 hours before and after taking the medication, avoid dairy products as well as antacids that contain aluminum, calcium, or magnesium. Tetracycline should be taken with a full glass of water while standing or sitting upright and should not be taken at bedtime (to avoid irritation of the lining of the throat and the tube leading to the stomach, known as the esophagus).

What side effects are possible with this medication?
Many medications can cause side effects. A side effect is an unwanted response to a medication when it is taken in normal doses. Side effects can be mild or severe, temporary or permanent.
The side effects listed below are not experienced by everyone who takes this medication. If you are concerned about side effects, discuss the risks and benefits of this medication with your doctor.
The following side effects have been reported by at least 1% of people taking this medication. Many of these side effects can be managed, and some may go away on their own over time.
Contact your doctor if you experience these side effects and they are severe or bothersome. Your pharmacist may be able to advise you on managing side effects.
- abdominal pain
- fingernail or toenail changes
- increased skin sensitivity to sunlight
- tongue discolouration
- vaginal yeast infections
Although most of the side effects listed below don’t happen very often, they could lead to serious problems if you do not seek medical attention.
Check with your doctor as soon as possible if any of the following side effects occur:
- symptoms ofhepatic cholestasis, or blockage of bile flow (a digestive fluid) from the liver; symptoms may include yellowing of the skin or eyes, intense itching and/or dark coloured urine
- symptoms of pancreatitis (e.g., abdominal pain on the upper left side, back pain, nausea, fever, chills, rapid heartbeat, swollen abdomen)

Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Antibiotic-related diarrhea: As with other antibiotics, tetracycline can cause a severe form of diarrhea associated with a condition known as pseudomembranous colitis. If you develop severe diarrhea while taking (or within a few weeks of taking) this medication, contact your doctor.
Bacterial resistance: Misuse of an antibiotic such as tetracycline may lead to the growth of resistant bacteria that will not be killed by the antibiotic. If this happens, the antibiotic may not work for you in the future. Although you may begin to feel better early in your course of treatment with tetracycline, you need to take the full course exactly as directed. Do not take tetracycline or other antibiotics to treat a viral infection such as the common cold; antibiotics do not kill viruses, and using them to treat viral infections can lead to the growth of resistant bacteria.
Liver function:Although not common, tetracycline can cause liver problems when taken for long periods of time or at high doses. If you experience symptoms of liver problems such as fatigue, feeling unwell, loss of appetite, nausea, yellowing of the skin or whites of the eyes, dark urine, pale stools, abdominal pain or swelling, and itchy skin, contact your doctor immediately.
Overgrowth of organisms: The use of antibiotics may allow organisms not killed by the antibiotic to overgrow. This may cause unwanted conditions such as yeast infections.
Sensitivity to sunlight: An exaggerated sunburn reaction may occur for some people who take this medication. Watch for this if you spend time in direct sunlight or ultraviolet light and ensure that sun protection measures are taken (e.g., wear sunscreen, a hat, and long sleeve shirts). At the first sign of skin redness, stop taking the medication and see your doctor about changing your prescription.
Tooth discolouration: The use of tetracycline during tooth development (from the second trimester of pregnancy to the age of 8 years) may cause permanent discoloration of the teeth (yellow-grey-brown). Though more commonly associated with long-term use of tetracyclines, this effect has also been known to occur after taking the medication for a short time. Tetracycline should therefore not be used by children 8 years old or younger unless other medications are unlikely to be effective or can’t be used.
Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: This medication passes in small amounts into breast milk. Tetracycline is not recommended for nursing women unless potential benefits outweigh the risks.
