Active ingredient

Doxycycline hyclate

Drug description

It is an antibiotic that belongs to the class of tetracyclines.


Doxycycline is used to treat a variety of infections caused by certain types of bacteria in small animals.  


Do not use, unless advised by a veterinarian, if your pet has liver disease or is expecting.  

Side effects

Vomiting, diarrhea and decreased appetite are the most common adverse effects. 

Doxycycline can also cause narrowing of the esophagus. If your pet has serious, worsening or persistent adverse effects, contact your veterinarian immediately.

Recommended follow-up

It is important to monitor if your pet's condition is improving and if there are any side effects. 

Drug interactions

Do not use doxycycline, except under the supervision of a veterinarian, if your pet is taking antacid, iron, kaolin, pectin, penicillin, phenobarbital, salicylate of bismuth or warfarin.  


At room temperature and protected from light.

Avoid excess heat or cold. 


It is very important to give at least 6 ml of water or food immediately after giving the medication, otherwise the tablet may remain stuck in the esophagus   and this can lead to esophagitis, that is, an inflammation of the esophagus, or narrowing of the esophagus. It is therefore important to ensure that your pet eats if you do not give it with water. Respect the expiry date of the product, as an expired product may be less effective or potentially harmful to your pet's health.   * Keep out of the reach of children and animals. *  

Moreover, as previously mentioned, this drug is an antibiotic. It is therefore very important to follow the prescription directions and finish it, because if you do not complete it, you may contribute to antibiotic resistance. Even if your pet has no clinical signs, there may still be bacteria that will develop and cause another infection. Your pet will have to receive another antibiotic because the bacteria will have become resistant to this antibiotic.
