Produktoppsummering

Tetracin is a medication containing the active ingredient Tetracycline Hydrochloride, available in capsule form. It belongs to the class of antibiotics known as tetracyclines and is commonly used to treat various bacterial infections. Tetracin works by inhibiting the growth and spread of bacteria, thereby helping the body’s immune system to fight off the infection. It is an effective and widely prescribed antibiotic with a long history of use in the treatment of bacterial infections.

Bruk

Tetracin capsules are prescribed to treat a variety of bacterial infections, including respiratory tract infections, urinary tract infections, skin infections, acne, and certain sexually transmitted diseases such as chlamydia and gonorrhea. It is effective against both gram-positive and gram-negative bacteria, making it a versatile treatment option for a range of infections. Tetracin is often used when other antibiotics have proven ineffective or when the infecting bacteria are resistant to other antibiotics.

Bruk anvisning

Tetracin capsules should be taken orally with a full glass of water, preferably on an empty stomach, at least one hour before or two hours after meals. Do not lie down for at least 10 minutes after taking the medication to prevent irritation of the esophagus. Follow the dosage instructions provided by your doctor or pharmacist carefully. It is important to complete the full course of treatment prescribed, even if your symptoms improve before the medication is finished.

Virkemåte

Tetracin works by inhibiting the production of proteins in bacteria, which are essential for their growth and replication. By interfering with protein synthesis, Tetracin prevents the bacteria from multiplying and spreading, allowing the body’s immune system to eliminate the infection. It also has anti-inflammatory properties that help reduce inflammation associated with certain infections, such as acne. Tetracin is bacteriostatic, meaning it stops the growth of bacteria, rather than killing them outright.

Dosering og administrering

The dosage of Tetracin capsules depends on the type and severity of the infection being treated, as well as your age, weight, and medical history. It is typically taken two to four times daily, spaced evenly throughout the day. The duration of treatment may vary from a few days to several weeks, depending on the condition being treated. Always take it exactly as prescribed by your doctor and do not adjust your dosage without consulting them first.

Fordeler

Tetracin offers several benefits in the treatment of bacterial infections, including its broad-spectrum activity against a wide range of bacteria, its oral administration, and its relatively low cost compared to other antibiotics. It is generally well-tolerated, with few serious side effects when used as directed. It is available in capsule form, making it convenient and easy to administer, even for children and elderly patients.

Vanlige bivirkninger

Common side effects of Tetracin may include nausea, vomiting, diarrhea, loss of appetite, and stomach upset. These side effects are usually mild and transient, resolving on their own as your body adjusts to the medication. However, if these side effects persist or worsen, contact your doctor for further guidance. In rare cases, it may cause more serious side effects such as allergic reactions, liver or kidney problems, or photosensitivity. Seek medical attention immediately if you experience any severe or persistent side effects.

Advarsler

Tetracin should not be used in children under the age of 8 years or in pregnant women, as it may cause permanent discoloration of the teeth and affect bone development in the fetus. It should also be used with caution in patients with liver or kidney impairment, as dosage adjustments may be necessary. It may interact with certain medications, supplements, or foods, so inform your doctor of all medications you are taking before starting treatment. Avoid prolonged exposure to sunlight or artificial UV rays while taking it, as it may increase the risk of sunburn or skin irritation.

Oppbevaringsinformasjon

Store Tetracin capsules at room temperature, away from moisture, heat, and light. Keep the medication out of reach of children and pets. Do not use it beyond the expiration date printed on the packaging. If you have any unused or expired medication, dispose of it properly according to local regulations.

Vanlige spørsmål

Is Tetracin safe in pregnancy?

No. Tetracin is contraindicated after the 15th week of pregnancy and in children under 8 years — it deposits in developing bone and teeth and causes permanent yellow-grey discoloration plus enamel hypoplasia. Avoid in lactation as well.

How should I take Tetracin to avoid oesophagitis?

Take with a full glass of water and remain upright (sitting or standing) for at least 30 minutes after each dose. Tetracyclines can cause severe pill-induced oesophagitis if they sit against the oesophageal mucosa.

Should I separate Tetracin from dairy and supplements?

Yes. Calcium (dairy, antacids), iron, magnesium, aluminium, and zinc all chelate tetracycline and dramatically reduce absorption. Take Tetracin at least 2 hours before or 6 hours after any of these.

Does Tetracin cause photosensitivity?

Yes. Sun exposure during a course of Tetracin can cause an exaggerated sunburn reaction. Wear high-SPF sunscreen (50+) and protective clothing; minimise direct UV exposure for the duration of treatment.

Does Tetracin interfere with oral contraceptives?

The clinical relevance is contested. Most modern guidance no longer requires barrier backup for short tetracycline courses, but if you experience breakthrough bleeding, use additional contraception during the course and for 7 days after.

Hva er de vanligste bivirkningene?

Nausea, abdominal upset, photosensitivity, oesophageal irritation, and oral/vaginal candidiasis. Less common: benign intracranial hypertension (severe headache + visual symptoms — stop and seek review), drug-induced hepatitis, and a rare rash.
