Medications

What it is for

Medications keeps the medicine cabinet: inventory, batches, movements and expiry. Its tabs are Inventory, Add, Report, Health dashboard, Use and spend and Unclassified.

Inventory

Each row is a batch of a product: batch code, purchase date, available quantity expressed as full bottles plus millilitres in the open bottle ("1 full bottle + 306.53 ml in the open bottle, of 1,000 purchased"), price per container and per ml with the value remaining, expiry date and days left, dose rule, withdrawal (meat and milk days), location and state. Filters cover stock state (expired, out of stock, expiring, low stock, in order, quarantine, discarded) and category. A line at the top says what needs attention; the default rules warn 60 days before expiry and below 20% stock.

Worked example of how a quantity reads: a 20 ml product with 5 unopened bottles and 15 ml left in the open one shows as "5 full bottles + 15 ml in the open bottle", which is 115 ml available.

Add: product versus batch

New product is the definition: trade name, manufacturer, category (a long veterinary list from antibiotics to diagnostic products, or a new one), subcategory, active ingredient, use, presentation, unit (ml, dose, tablet, g, other), content per container, route, the dosing rule, concentration, withdrawal in meat and milk, discard-after-opening hours and notes. "Search medication" fills it from a directory and "Create from photo" reads the bottle, box or invoice for you to review before saving. New batch is a purchase of an existing product: batch, supplier, purchase date, expiry, quantity bought and total price.

The dosing rule

Define exactly one rule with its unit: per kg of liveweight or flat per animal, with optional minimum and maximum. The Chute only calculates a dose when a valid rule exists; without one it asks for validation instead of inventing a number. Example: a rule of 0.1 ml/kg on a 50 kg ewe gives 5 ml, and that volume is subtracted from the open bottle when the treatment is saved.

Use and spend

Use and spend counts applications and treatments separately (a three-dose course is one treatment and three applications), by product, category or problem, with animals treated, quantity, spend, spend per animal, spend per treatment and repeat rate. Applications without a batch price or quantity are left out of the spend and the page says so, because counting them as zero would make the report cheaper without warning.

Health dashboard

The Health dashboard shows where the health work concentrates: problems by distinct animals affected, animals treated repeatedly (two distinct treatments for the same problem; three doses of one course are not a relapse) and areas to review. It states that these are observations, not diagnoses, and that heavy use of a product can be a preventive protocol, not disease.

Decisions it supports

Reorder before a product runs out, stop using a batch that is about to expire, see which problem costs most per animal, and give the vet a list of animals that repeat.
