Sumycin is the brand name for a medication called Tetracycline. It is an antibiotic that belongs to the class of drugs known as tetracyclines. Tetracycline is primarily used to treat various bacterial infections.

Tetracycline works by inhibiting the growth of bacteria and interfering with their ability to produce essential proteins. This disrupts the bacteria's ability to multiply and survive, thereby helping to clear the infection.

Sumycin, which contains the active ingredient tetracycline, can interact with various medications, supplements, and substances. Here are some common interactions to be aware of:

  1. Calcium, magnesium, aluminum, iron supplements, and antacids: These substances can reduce the absorption of tetracycline when taken within two hours of Sumycin. It is advisable to separate their administration by at least two hours.
  2. Dairy products: Calcium-rich foods, such as milk, cheese, and yogurt, can also interfere with the absorption of tetracycline. It is recommended to avoid consuming dairy products within two hours of taking this drug.
  3. Oral contraceptives: Tetracycline may decrease the effectiveness of oral contraceptive pills. It is advisable to use alternative or additional contraceptive methods while taking Sumycin and for a short period after completing the treatment.
  4. Blood-thinning medications: Tetracycline may enhance the effects of certain blood-thinning medications, such as warfarin. Close monitoring of blood clotting parameters may be necessary if you are taking both medications concurrently.
  5. Retinoids: Concurrent use of tetracycline and retinoids, such as isotretinoin or acitretin, may increase the risk of a condition called intracranial hypertension. This can manifest as severe headaches, blurred vision, and dizziness.
  6. Other antibiotics: Some antibiotics, such as penicillin and cephalosporins, may interfere with the effectiveness of tetracycline.


Here are some important warnings associated with the use of Sumycin:

  1. Allergic reactions: Some individuals may experience allergic reactions to tetracycline antibiotics, including Sumycin. Seek immediate medical attention if you develop signs of an allergic reaction, such as rash, itching, swelling, severe dizziness, or difficulty breathing.
  2. Photosensitivity: Tetracycline antibiotics can increase the skin's sensitivity to sunlight and ultraviolet (UV) light. Avoid prolonged exposure to sunlight, tanning beds, and UV lamps during treatment with Sumycin. Use protective clothing and sunscreen with a high sun protection factor (SPF) when outdoors.
  3. Children: Tetracycline antibiotics can cause permanent discoloration of teeth in children younger than 8 years old. It may also affect bone growth.
  4. Liver and kidney function: If you have impaired liver or kidney function, you may need to adjust the dosage of Sumycin or monitor you closely while you are taking the medication.
  5. Drug resistance: Overuse or inappropriate use of antibiotics, including tetracyclines, can lead to the development of drug-resistant bacteria.

Sumycin and Alcohol

It is generally advisable to avoid consuming alcohol while taking Sumycin. There are a few reasons for this recommendation:

  1. Decreased effectiveness: Alcohol may interfere with the effectiveness of antibiotics, including tetracyclines. It can reduce the absorption and effectiveness of the medication, potentially compromising its ability to treat the infection.
  2. Increased side effects: Both Sumycin and alcohol can individually cause certain side effects. Consuming alcohol while taking Sumycin may increase the risk and severity of these side effects. For example, both substances can cause gastrointestinal upset, dizziness, and headache. Combining them may intensify these symptoms and lead to increased discomfort.
  3. Liver metabolism: Both alcohol and tetracycline are metabolized by the liver. Concurrent use may put additional stress on the liver and potentially affect its ability to metabolize the substances effectively.
  4. Dehydration: Alcohol is known to cause dehydration, and tetracycline can also contribute to dehydration as a potential side effect. Combining alcohol and Sumycin may exacerbate this effect and increase the risk of dehydration.

Pregnancy and Sumycin

Sumycin should not be recommended during the time of pregnancy as it may harm the unborn baby. The doctor should be consulted whenever you plan on becoming pregnant. During breastfeeding, sumycin may appear in the milk. Therefore, the drug should not be taken when the mother is breastfeeding.

Tetracycline antibiotics are seen to cause harm to the foetus. Using the drugs belonging to the tetracycline class at the time of tooth development may result in permanent discolouration of the teeth (yellowish brown). This time period is generally applicable during the last half of the pregnancy.
