Zeniquin® is a prescription antibiotic used in dogs and cats. It helps treat susceptible bacterial infections affecting skin, soft tissue, and the urinary tract. This page explains how the treatment works, how to use it safely, and how to plan US shipping from Canada, including tips for buying without insurance.
What Zeniquin Is and How It Works
Border Free Health connects U.S. patients with licensed Canadian partner pharmacies; prescriptions are verified with prescribers before dispensing.
This fluoroquinolone antibiotic contains marbofloxacin, which blocks bacterial DNA gyrase and topoisomerase IV. That action can stop bacteria from growing and helps your veterinarian manage confirmed or suspected infections. Use is guided by culture and susceptibility when available, and by your prescriber’s clinical judgment.
For confirmed skin and soft tissue infections, marbofloxacin tablets may be used once daily. The treatment can be given with food to reduce stomach upset. Follow the full course as prescribed, even if your pet seems better after a few days, to support treatment success and reduce the chance of resistance.
Always provide your prescriber with a full medication list for your pet. Antacids, sucralfate, or supplements with aluminum, magnesium, calcium, or iron can lower absorption. If these are essential, your prescriber may advise separating doses to maintain effect.
Who It’s For
This medicine is used in dogs and cats for susceptible infections of the skin, soft tissue, or urinary tract, as directed by a veterinarian. The class can also be considered for respiratory infections when appropriate testing supports use.
Use marbofloxacin for dogs only under veterinary direction, particularly in growing animals. Fluoroquinolones may affect developing cartilage, so use in young, large-breed dogs requires extra caution. For cats, your prescriber will consider age, kidney health, and overall status before therapy.
Avoid use if your pet has a known allergy to fluoroquinolones. Use caution in animals with seizure disorders or those taking drugs that lower the seizure threshold. Pregnant or lactating pets should be treated only if the expected benefit outweighs potential risk, as determined by a veterinarian.
Dosage and Usage
Your veterinarian will determine the dose based on your pet’s weight and the infection being treated. The usual schedule is once daily. Give the dose at about the same time each day. Tablets may be given with a small meal or treat if stomach upset occurs. Do not crush unless your prescriber says it is acceptable for your pet.
Provide fresh water, monitor appetite, and watch for changes in stool. If vomiting occurs shortly after dosing, contact your veterinarian for guidance. Never stop the medicine early unless your prescriber directs you to stop. Stopping too soon can allow bacteria to return.
Tell your veterinarian if your pet takes antacids, sucralfate, or mineral supplements. These can reduce absorption; separation of administration times may be recommended. Do not give with dairy-heavy meals unless your prescriber approves.
Follow label directions and your veterinarian’s instructions. For detailed, species-specific dosing information, refer to the official label and your clinic’s guidance.
Strengths and Forms
The treatment is supplied as film-coated oral tablets in several strengths. Availability may vary by pharmacy and over time.
- Zeniquin 50mg
- Other common strengths include 25 mg, 100 mg, and 200 mg tablets
Ask your veterinarian which tablet size best matches your pet’s weight and treatment plan.
Missed Dose and Timing
If you miss a dose, give it when you remember the same day. If it is close to the next scheduled dose, skip the missed dose and return to the regular schedule. Do not double up to make up for a missed dose. Consistent timing supports steady levels and treatment success.
Storage and Travel Basics
Store tablets at room temperature in the original, child-resistant container. Keep the bottle tightly closed and away from moisture and direct light. Place out of reach of children and other animals. Do not store in a bathroom or near a sink where humidity is high.
When you travel, keep the label visible on the pharmacy container. Pack only the amount needed plus a small extra buffer as approved by your prescriber. Carry a copy of the prescription or a clinic invoice if traveling between states. Use a daily reminder to help keep on-time dosing while away from home.
Benefits
This antibiotic class is valued for once-daily administration and broad coverage against many Gram-negative and select Gram-positive organisms. Film-coated tablets are straightforward for home dosing. Completing the full course as prescribed supports recovery and helps limit resistance development. Using culture results where possible can help target therapy.
Side Effects and Safety
- Digestive upset: vomiting, soft stool, or reduced appetite
- Lethargy: mild tiredness early in therapy
- Behavior change: restlessness or agitation in sensitive pets
Serious effects are uncommon. However, fluoroquinolones may lower the seizure threshold in animals with neurologic disorders. Use with care in growing dogs due to potential cartilage effects. Allergic reactions can occur in rare cases. Stop the medicine and seek urgent veterinary care for collapse, facial swelling, hives, severe vomiting, or bloody diarrhea.
In pets also treated with insulin or sulfonylureas, no direct hypoglycemia risk is typical for this class, but always monitor for unusual signs when treatments change. Report unexpected symptoms to your veterinarian promptly.
Drug Interactions and Cautions
Tell your veterinarian about all medicines and supplements your pet takes. Antacids, sucralfate, and products containing aluminum, magnesium, calcium, or iron can reduce absorption; spacing doses may help. Theophylline and certain nonsteroidal anti-inflammatories may require monitoring when used together with this antibiotic class. Avoid giving with vitamins or minerals at the same time unless your prescriber approves.
Use extra caution in pets with kidney impairment, seizure disorders, or in rapidly growing large-breed dogs. If your pet shows joint pain or limping during therapy, contact your veterinarian.
What to Expect Over Time
Your pet may begin to act more comfortable as the infection comes under control. Appetite and activity often trend toward normal with effective therapy. It is important to complete the prescribed duration, even if signs improve earlier. Keep follow-up appointments so your prescriber can check progress and adjust plans if needed. If signs persist or worsen, contact the clinic for guidance and possible culture testing.
Compare With Alternatives
Other veterinarian-prescribed options may be appropriate depending on the organism and site of infection. Enrofloxacin is another fluoroquinolone used in pets; see Baytril for details. For many skin and soft tissue infections, a beta-lactam combination may be chosen; see Clavamox as a common alternative. Your veterinarian will decide based on testing, history, and tolerance.

Availability and Substitutions

When suitable, generic Zeniquin may be considered if your prescriber agrees. Do not switch products without veterinary guidance.
Patient Suitability and Cost-Saving Tips
This therapy may be a fit for adult dogs and cats with susceptible infections, under veterinary supervision. It is not suitable for pets with known fluoroquinolone allergy. Caution is advised in growing large-breed dogs, pregnant or nursing pets, and animals with seizure disorders or significant kidney impairment.
To manage costs, ask your prescriber about a multi-month plan when appropriate. Larger tablet counts can reduce the per-tablet cost for long courses. Set refill reminders so you do not miss doses between renewals. Review the Pet Medications section to see related options for your pet’s care journey.

Can my pet take this antibiotic with food?
Yes. Many veterinarians allow giving this antibiotic with a small meal or treat, especially if your pet has a sensitive stomach. Food can help reduce nausea or vomiting. If your pet is on antacids, sucralfate, or mineral supplements, ask about spacing doses so absorption is not reduced. Follow your veterinarian’s instructions on timing and duration for the specific infection being treated.
How long does treatment usually last?
Course length varies by infection type, location, and how your pet responds. Some skin or urinary infections may need a shorter course, while deeper or complicated infections can require longer. Your veterinarian will set the duration and any needed recheck visits. Always finish the prescribed course unless your prescriber directs a change. Stopping early can allow bacteria to return.
What should I do if my pet vomits after a dose?
If vomiting occurs soon after dosing, call your veterinary clinic for advice. Your prescriber may recommend giving the next dose with a small meal, adjusting timing, or monitoring at home. Do not repeat the dose without guidance. If vomiting is severe, persistent, or accompanied by lethargy, diarrhea, or signs of pain, seek veterinary care promptly.
Are there pets who should not use this medicine?
Avoid use in animals with a known allergy to fluoroquinolones. Use caution in growing large-breed dogs because this antibiotic class can affect developing cartilage. Pets with seizure disorders or significant kidney impairment may need close monitoring or a different option. Pregnant or nursing animals should receive therapy only if the expected benefit outweighs risk, as determined by a veterinarian.
Can I give antacids or mineral supplements at the same time?
Products containing aluminum, magnesium, calcium, or iron can reduce absorption. If your pet needs these, ask your veterinarian about spacing doses by several hours. Do not change schedules without professional input. Keeping a simple dosing calendar can help you manage timing for all medicines and reduce missed doses.
Do I need a prescription from my veterinarian?
Yes. This is a prescription-only veterinary antibiotic. Your veterinarian will assess the infection, review your pet’s history, and decide if it is appropriate. Border Free Health verifies prescriptions with the prescriber before dispensing. Keeping your clinic’s contact details up to date can help avoid delays when your order is processed.
What signs mean I should call the vet right away?
Contact your veterinarian urgently for severe vomiting, bloody diarrhea, facial swelling, hives, collapse, seizures, or sudden weakness. Also call if your pet shows new limping, joint pain, or continued fever. These signs may indicate an adverse reaction or that the infection is not responding as expected. Your prescriber can advise next steps based on your pet’s condition.
