- Urethritis (inflammation of the urethra), cervicitis (inflammation of the cervix), proctitis (inflammation of the rectum), lymphogranuloma venereum (infection characterized by ulcers in the genitals followed by inflammation of the lymph nodes), granuloma inguinale (purulent ulceration of the genitals), pelvic inflammatory disease, syphilis in patients allergic to penicillin, acute epididymo-orchitis (inflammation of the testicles, purulent and mainly affecting newborns).
- Ocular infections such as: trachoma, inclusion conjunctivitis.
- Typhus and other infections caused by microorganisms called rickettsias.

- prevention of malaria (transmitted through mosquito bites) and prevention of anthrax after exposure to bacteria that cause this disease.
2. What you need to know before you take Dosil
Do not take Dosil
- If you are allergic to doxycycline, any other tetracycline, or any of the other components of this medicine (listed in section 6).
- If you are using methoxyflurane (a medicine used for anesthesia), as severe kidney toxicity with fatal outcome may occur.
Warnings and precautions
Consult your doctor or pharmacist before starting to take Dosil:
- it is recommended to use total sunblock creams and avoid sun exposure or ultraviolet radiation, as skin redness may occur. If this happens, you should consult your doctor,
- the use of antibiotics can increase the risk of developing infections with microorganisms that are not sensitive to treatment, including fungi, so your doctor will monitor the appearance of any possible signs of infection.
Children
- Dosil should not be used in children during the teething period (last half of pregnancy, infants, and children under 8 years) because it may cause permanent tooth discoloration, as well as delayed bone development.
Use in children and adolescents
- In children under 8 years, the use of Dosil is not recommended.
- In children over 8 years and up to 45 kg in weight, there is another presentation more suitable for dose adjustment.
- In children over 8 years and over 45 kg in weight, the same dose as in adults is recommended, see section 3.
Taking Dosil with other medicines
Inform your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.
Certain medicines may interact with Dosil. In these cases, it may be necessary to change the dose or discontinue treatment with one of the medicines. It is especially important that you inform your doctor if you are using any of the following medicines:
- Penicillin, as Dosil may interfere with its effect.
- Oral contraceptives, as Dosil may reduce their effectiveness.
- Anticoagulants (such as warfarin), as Dosil may alter their effect.
- Antacids (medicines used to calm stomach acidity) and other medicines that contain aluminum, calcium, or magnesium, and medicines that contain iron or bismuth salts, as they may reduce the effect of Dosil.
- Antiepileptics and barbiturates (medicines for severe insomnia and seizures), as they may reduce the effect of Dosil.
- Methoxyflurane (a medicine used for anesthesia), as when used in combination with tetracycline antibiotics, such as Dosil, severe kidney toxicity may occur.
Taking Dosil with food, drinks, and alcohol
- You should avoid consuming alcohol during treatment with Dosil, as alcohol reduces the effect of doxycycline.
- It is essential to take Dosil during a meal, accompanied by a large glass of water or milk, to avoid esophageal irritation (see section 3).
Pregnancy and breastfeeding
If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine.
Pregnancy
The use of Dosil is not recommended during pregnancy, as it may cause disorders in the development of the child's bones and teeth. Your doctor will decide on the convenience of using Dosil in these cases.
It is essential that during treatment with Dosil, you use contraceptive methods to avoid becoming pregnant. Oral contraceptives (hormonal) may not be effective, as taking Dosil reduces the contraceptive effect, and therefore, barrier methods are recommended.
Breastfeeding

Driving and using machines
There is no evidence that Dosil alters the ability to drive or use machines.
