Frequently Asked Questions
The Silospen Drop Calculator provides high accuracy across the full range of equine sizes when proper weight measurements are used. For standard light horse breeds (450-600 kg), the calculator typically achieves accuracy within ±2-3% of ideal dosing when based on actual scale weights. For ponies and miniature horses (150-350 kg), accuracy remains within ±3-5% due to the increased impact of small absolute errors in smaller patients. Draft breeds (700-1000 kg) show similar accuracy to light horses when proper weight assessment is used. The calculator incorporates breed-specific adjustment factors that account for metabolic differences between horse types. However, accuracy depends heavily on correct weight input - using a weight tape provides reasonable estimates (±5-10%), while visual estimation can reduce accuracy to ±15-25%. For critical cases or patients with unusual body condition, actual scale weights are recommended to maximize calculation accuracy.
If you accidentally administer too many Silospen drops, take immediate action based on the extent of the overdose. For minor overdoses (up to 25% above calculated dose), monitor the horse closely for 4-6 hours for signs of increased sedation, gastrointestinal upset, or behavioral changes. Ensure fresh water is available and consider delaying the next scheduled dose by 2-4 hours. For moderate overdoses (25-50% above calculated dose), contact your veterinarian immediately for guidance. They may recommend specific monitoring protocols or symptomatic treatment. Withhold the next scheduled dose and monitor vital signs every 2 hours. For significant overdoses (more than 50% above calculated dose), this constitutes a veterinary emergency. Contact your veterinarian immediately and be prepared to transport the horse if advised. Watch for serious signs including severe lethargy, coordination problems, significant gastrointestinal distress, or behavioral abnormalities. In all overdose situations, maintain detailed records of the miscalculation and the horse's response for future reference and veterinary consultation.
Silospen drops are specifically formulated for oral mucosal administration and generally should not be mixed with food or other medications. When mixed with food, several issues can occur: the medication may not be fully consumed if the horse refuses the medicated portion, the absorption may be significantly delayed or reduced as it passes through the digestive system rather than being absorbed through the oral mucosa, and the precise dosing becomes uncertain. Mixing with other liquid medications is also not recommended due to potential chemical interactions, altered absorption rates, and difficulty ensuring the horse receives the full combined dose. The designed administration method - placing drops directly into the interdental space or onto oral mucosa - ensures optimal absorption and bioavailability. If a horse consistently refuses direct administration, consult your veterinarian about alternative formulations or administration techniques rather than compromising the medication's effectiveness through improper mixing. Some compounding pharmacies can create custom formulations, but these require specific veterinary prescription and oversight.
Silospen drops typically begin to take effect within 20-45 minutes after proper administration, with peak plasma concentrations reached within 1-2 hours. The rapid onset of action is due to the oral mucosal absorption route, which bypasses first-pass liver metabolism and allows direct entry into the systemic circulation. Several factors influence the exact onset time: the specific administration site (sublingual administration may act slightly faster than interdental space), individual variation in oral mucosa health and blood flow, whether the horse has recently eaten or drunk (which can dilute the medication), and the specific condition being treated. Pain relief and anti-inflammatory effects typically become noticeable within the first hour, with maximum therapeutic benefit achieved by 2-3 hours post-administration. The duration of effect generally lasts 6-12 hours depending on the dosage, individual metabolism, and the condition being treated. For chronic conditions, optimal therapeutic benefit may require 2-3 days of consistent dosing to achieve stable drug levels and full anti-inflammatory effects.
Yes, several specific conditions may make Silospen unsuitable or require special consideration. Absolute contraindications include known hypersensitivity to the active ingredient or any component of the formulation, severe liver disease with significantly impaired function, and active gastrointestinal ulceration. Relative contraindications (requiring careful risk-benefit assessment and possible dosage adjustment) include moderate renal impairment, history of gastrointestinal ulcers, concurrent use of other ulcerogenic medications, bleeding disorders, and pregnant or lactating mares. Special caution is also warranted in horses with dehydration, hypotension, or significant electrolyte imbalances. Geriatric horses and those with multiple health issues may require reduced dosing and enhanced monitoring. Additionally, competition horses may have restrictions based on governing organization rules. Before initiating Silospen therapy, a thorough veterinary examination should assess these factors, and baseline blood work (including liver and kidney parameters) is often recommended for horses with known health issues or those requiring long-term treatment.
Silospen drops should be stored in their original container at controlled room temperature between 15-25°C (59-77°F), protected from light and moisture. Avoid freezing and excessive heat - do not store in vehicles or direct sunlight. The manufacturer's sealed shelf life is typically 24 months from the manufacturing date when stored properly, as indicated on the packaging. Once opened, the drops should generally be used within 30 days due to potential contamination and degradation, though some formulations may have different recommendations - always check the specific product information. Proper storage also includes keeping the bottle tightly closed when not in use and storing it upright to prevent leakage. If the medication changes color, develops particles, or develops an unusual odor, it should be discarded regardless of the expiration date. For accurate dosing, it's important to note that extreme temperatures can affect the viscosity and drop size, potentially impacting dosage accuracy. Always record the opening date on the bottle and establish a system to ensure expired medications are not used.
