The way oral flea and tick medicine works depends on the type of medication:
- Systemic medications: These medications are absorbed into your pet's bloodstream and distributed throughout the body. They kill or repel fleas and ticks when they come into contact with your pet's skin or coat.
- Topical medications: These medications are applied directly to your pet's skin or coat. They work by creating a barrier against fleas and ticks, preventing them from attaching and feeding.
Some common side effects of oral flea and tick medicine include:
- Vomiting
- Diarrhea
- Lethargy
- Drooling
- Muscle tremors
- Seizures
These side effects are usually mild and go away within a few days. If your pet experiences severe side effects, it's important to contact your veterinarian immediately.
Oral flea and tick medicine is a safe and effective way to keep your pet free of fleas and ticks. However, they can cause serious side effects, so it's important to use them only as directed and to be aware of the potential risks.
