Proper Storage Guidelines for Mometamax Otic Suspension
Mometamax Otic Suspension is a widely prescribed veterinary medication used to treat external ear infections (otitis externa) in dogs caused by both bacterial and fungal agents. Given its specific formulation and intended use, correctly storing Mometamax is vital to preserve its efficacy and safety.
Understanding Mometamax Composition
This medication is a triple-combination otic suspension made up of:
- Gentamicin sulfate – an aminoglycoside antibiotic effective against a broad spectrum of Gram-negative and some Gram-positive bacteria.
- Mometasone furoate monohydrate – a powerful corticosteroid that reduces swelling, redness, and itching associated with inflammation.
- Clotrimazole – a broad-spectrum antifungal that targets yeast such as Malassezia pachydermatis.
The suspension is delivered in a mineral oil-based gel, ensuring consistent viscosity and effective application in the ear canal.
Should You Refrigerate Mometamax?
No, refrigeration is not required for Mometamax. Instead, the manufacturer recommends that it be stored at a controlled room temperature between 2°C and 25°C (36°F and 77°F). This range ensures the product retains its chemical stability and therapeutic potency throughout its usage period.
Best Practices for Storing Mometamax
- Keep the bottle in a cool, dry place away from direct sunlight or sources of heat.
- Avoid freezing the medication, as extreme cold can alter its consistency and effectiveness.
- Always re-cap the bottle tightly after each use to prevent contamination and evaporation.
- Store the medication out of reach of children and pets to avoid accidental ingestion or misuse.
Product Shelf Life and Usage Guidelines
After opening, Mometamax should be used within 28 days. Prolonged use beyond this period is not recommended as the medication’s efficacy may diminish and the risk of contamination increases.
- Before application, shake the bottle well to ensure uniform distribution of the ingredients.
- Store the medication in its original bottle to preserve labeling and dosing instructions.
Also note that Mometamax should not be used past its expiration date. Doing so may result in reduced potency and risk the development of resistant infections.
What Happens If Mometamax Is Improperly Stored?
If Mometamax is stored outside the recommended temperature range—such as being exposed to high heat or refrigerated for an extended period—it may:
- Separate or thicken, making accurate dosing problematic.
- Lose potency against the targeted pathogens.
- Pose a risk for increased side effects or ineffective treatment.
Why Not Refrigerate?
While refrigeration may seem like a way to preserve medication, doing so with Mometamax can adversely affect the mineral oil-based gel formulation. Cold temperatures may change the consistency of the gel, making it harder to administer effectively in the pet’s ear canal.
Signs of Deterioration
If you notice any of the following signs, consult your veterinarian and consider discarding the product:
- Change in color or consistency
- Unusual odor
- Clumping or separation of ingredients
- Cracked or compromised packaging
Additional Tips for Pet Owners
When handling Mometamax or any veterinary medication, it's important to:
- Wash your hands before and after each application.
- Wear gloves if your veterinarian advises it.
- Use the dosage prescribed based on your dog’s weight and condition severity.
- Complete the full course of treatment even if symptoms improve early.
Avoid using the medication in cats unless explicitly directed by a veterinarian, as Mometamax is not labeled for feline use.
Conclusion
To ensure your pet receives the full benefit of Mometamax Otic Suspension, store it at room temperature (36°F–77°F) and never refrigerate or freeze it. Follow all instructions from your veterinarian, and monitor your pet for any signs of adverse reactions or worsening symptoms. Proper storage not only maximizes drug effectiveness but also safeguards your pet’s health during treatment.
