Procytox is an oral cyclophosphamide medicine used in veterinary oncology. This page explains key uses, typical handling, and safety checks. It also outlines access with US shipping from Canada and Cyclophosphamide 50 mg without insurance.
What Procytox Is and How It Works
Procytox® contains cyclophosphamide, an alkylating agent. It becomes active in the liver and forms compounds that cross-link DNA. These actions can slow or stop rapidly dividing cells. In pets, clinicians may use this medicine within combination protocols to manage lymphoma and other tumors.
CanadianInsulin.com is a prescription referral platform. We verify prescriptions with your prescriber when required, and licensed Canadian pharmacies dispense your order.
This treatment is given under veterinary supervision. It may be used alone or with other chemotherapies. Your veterinarian will plan cycles, monitoring, and supportive care based on your pet’s condition and lab results.
Who It’s For
This therapy may be part of a plan for dogs and cats with lymphoma, mast cell disease, certain sarcomas, or other responsive tumors. It may also be included in immune-mediated disease regimens when appropriate. Animals that are pregnant or nursing should not receive it. Pets with severe bone marrow suppression, serious uncontrolled infection, or a known allergy to cyclophosphamide require alternative options. If your pet has liver or kidney impairment, the prescriber may adjust the approach and increase monitoring in line with the label and current veterinary practice. For a broader view of related options, explore our Oncology category.
Dosage and Usage
Clinicians may prescribe Cyclophosphamide 50 mg tablets or other strengths as part of cyclic protocols. Doses and schedules vary by diagnosis, concurrent drugs, and tolerance. Follow your veterinarian’s exact directions. Do not change the plan on your own.
Give tablets as instructed, often in the morning. Offering with a small meal can reduce stomach upset in some pets. Ensure good hydration and provide regular chances to urinate, which may help limit bladder irritation. Handle tablets with disposable gloves and wash hands after handling. Keep tablets away from children and other animals. Do not crush or split unless your clinician specifically directs and you have proper handling guidance. If another caretaker administers the dose, share the handling steps and safety precautions.
Strengths and Forms
Common presentations include Procytox 50mg tablets and other tablet strengths. Injectable cyclophosphamide products also exist, but many home regimens use tablets. Availability can vary by pharmacy and by current supply. Your order may be filled with a clinically equivalent brand or generic as allowed.
Missed Dose and Timing
If you miss a scheduled dose, contact your veterinary team for instructions. In general, give it when remembered if it is not close to the next planned dose. Do not double up to make up a missed dose. If your pet vomits shortly after a dose, ask your clinician before re-dosing. Keep a simple log of doses, observed side effects, and any missed doses to support follow-up decisions.
Storage and Travel Basics
Store tablets in the original container with the label intact. Keep them dry and at room temperature away from heat and direct light. Secure the medicine out of reach of children and other animals, ideally in a locked cabinet. For travel, keep tablets in a sealed, secondary container within your carry-on. Bring the prescription label, a copy of directions, and your veterinarian’s contact information. Avoid crushing or breaking tablets during transit. If you travel across borders, allow extra time for documentation checks. Dispose of unused or expired items through take-back programs; do not discard them in household trash or wastewater.
Benefits
This medicine can be integrated into multi-drug protocols used by veterinarians for many cancers. Oral dosing allows home administration in many cases. Combination regimens can be designed around tolerance, monitoring results, and the pet’s overall goals of care. The treatment class has long clinical experience, and dosing plans can be adapted by the prescriber as needed within accepted practice.
Side Effects and Safety
- Lower energy or reduced appetite
- Vomiting or soft stool
- Increased thirst or urination
- Low white blood cell counts on lab tests
- Hair coat changes in some breeds
- Urinary discomfort or blood in urine
Serious risks include myelosuppression with infection risk, bladder inflammation, and rare heart or liver effects at certain exposures. Seek veterinary care if your pet develops fever, marked lethargy, difficulty breathing, persistent vomiting, or painful urination. Your clinician may schedule regular bloodwork and urinalysis during therapy. Report all medicines, supplements, and recent vaccines to help your team reduce preventable interactions.
Drug Interactions and Cautions
Use caution with other myelosuppressive therapies, including many chemotherapies. Drugs that alter liver enzymes can change exposure; your clinician may consider this when planning protocols. Avoid live vaccines during and after immunosuppressive therapy unless your veterinarian advises otherwise. Supportive antibiotics may be used when indicated; discuss choices if your pet has a history of reactions. For background on common antimicrobials, see our article on Cephalexin For Dogs. For broader category context, review Immunosuppressants.
What to Expect Over Time
Many pets receive this therapy in cycles with planned rest periods. Your veterinarian will monitor response and tolerance and adjust the plan when needed. Some effects, like changes in blood counts, are detected on lab tests rather than by observation alone. Owners often find a simple calendar and symptom log helpful. If your pet’s activity or appetite changes, share that detail during check-ins. Immune-modulating therapies and prior treatments can influence infection risk; for general insights on allergy immunomodulators, see Apoquel For Dogs.
Compare With Alternatives
Veterinarians may consider other agents within multi-drug protocols. Chlorambucil is an oral alkylating option used in some chronic indications and for certain small-cell presentations; see Leukeran. For injectable anthracycline therapy within combination plans, review Doxorubicin. The choice depends on diagnosis, tolerance, access, and the overall protocol.
Pricing and Access
We display Canadian pharmacy pricing with clear options for quantities and refills. You can request fulfilment with US shipping from Canada for convenient home delivery. If you compare online offers, review dispensing pharmacy credentials and handling practices. For online ordering, many pet owners search for Cyclophosphamide 50 mg online to check availability and estimated costs. We provide transparent checkout and encrypted payment processing. If you are looking for occasional promotions, visit our Promotions page. Cash-pay budgets vary by protocol and duration; your veterinary team can help plan refills.
Availability and Substitutions
Stock may vary by brand, strength, and tablet count. If a certain presentation is unavailable, your prescriber may recommend an equivalent option or revise the regimen. Discuss how any change could influence monitoring or supportive care. If you are comparing total therapy budgets, factor in labs and visits in addition to Cyclophosphamide 50 mg cost. We cannot provide restock dates, but we will show current options on the product page when available.
Patient Suitability and Cost-Saving Tips
Pets with adequate organ function and an acceptable baseline blood count profile may be candidates, subject to clinician judgment. Those with concurrent infections, pregnancy, or severe cytopenias often need a different plan. Ask your clinician whether multi-month fills make sense for your protocol. Consider refill reminders to avoid gaps. Owners sometimes review Cyclophosphamide 50 mg price differences across tablet counts to plan expenses. For broader browsing, you can scan our Pet Medications category.

How does cyclophosphamide work in pets?
Cyclophosphamide is an alkylating agent. After activation in the liver, it forms compounds that cross-link DNA. This DNA damage interferes with replication and can slow or stop rapidly dividing cells. Veterinarians use it alone or in combination protocols to manage lymphoma and other cancers in dogs and cats. It also has immunosuppressive effects, which may be useful in certain immune-mediated diseases. Your clinician will plan schedules and monitoring to balance potential benefit with tolerability.
What monitoring is typical during treatment?
Most pets need periodic bloodwork to assess white cells, red cells, and platelets. Urinalysis can help detect bladder irritation. Your clinician may also check liver and kidney values, especially if other medicines are used. Frequency depends on diagnosis, dose intensity, and past tolerance. Share a simple log of doses and symptoms to support decisions at each visit. Call your veterinary team if you notice fever, marked lethargy, or painful urination, as these can indicate complications that require prompt attention.
Can owners split tablets or adjust doses?
Do not split tablets or adjust doses unless your veterinarian specifically directs you to do so and you have proper handling guidance. Many regimens rely on precise dosing and cycle timing. Splitting can increase handling risk and reduce accuracy. If your pet needs a different amount, ask about alternate strengths or compounded solutions prepared under appropriate standards. Always handle this medicine with gloves and wash hands after contact. Keep tablets away from children and other animals.
What are signs of low white blood cells?
Low white blood cells can increase infection risk. Common warning signs include fever, unusual tiredness, pale gums, poor appetite, or rapid breathing. Some pets show few outward signs, which is why scheduled bloodwork is important. If your pet seems unwell between visits, call your veterinary team. They may advise an exam, additional labs, or supportive care. Never give over-the-counter medicines without checking first, as some can mask symptoms or interact with the chemotherapy plan.
How can I reduce bladder irritation risk?
Encourage regular hydration and frequent bathroom breaks, especially on dosing days. Morning dosing can help by allowing more daytime urination. Your veterinarian may add protective medicines or adjust schedules if irritation occurs. Report any straining, blood in urine, or discomfort immediately. Do not withhold water unless instructed for specific tests. Keeping a diary of urinary habits can help your clinician detect early changes and decide whether to modify the plan.
Is this drug safe with vaccines?
Immunosuppressive therapies can reduce vaccine responses and increase risk from live vaccines. Your veterinarian may defer certain vaccines during active chemotherapy or schedule them during recovery periods. They may also recommend inactivated vaccines when appropriate. Share a full vaccine history before starting treatment. Discuss household pet vaccination, too, since exposure risk can change when one pet is immunosuppressed. Always follow your clinician’s timing advice for preventive care.
What should I do if my pet vomits after a dose?
Contact your veterinarian for guidance before re-dosing. They may ask when the dose was given, how much was vomited, and whether other symptoms are present. They might recommend withholding food briefly and then offering a small meal later, or adding an anti-nausea medicine in future cycles. Do not give an extra dose unless your clinician tells you to. Track episodes in a log so the team can adjust the plan if vomiting becomes frequent.
