Buy it in September, thank yourself in January.
Nobody shops well with a fever. A small shelf of the right things makes the bad week easier.
The shelf
A digital thermometer, plain paracetamol or ibuprofen, saline spray for blocked noses, oral rehydration salts, honey for coughs, and tissues. That short list handles the honest treatment of most colds and flu, which is comfort while your immune system does the work.
What to skip
Vitamin C megadoses do not prevent colds. Echinacea, zinc lozenges and most combination cold-and-flu formulas add little beyond the plain painkiller already in them, at several times the price. Antibiotics do nothing against these viruses at all.
When a cold is something more
Trouble breathing, chest pain, fever above 39.4 C that will not settle, confusion, a stiff neck with rash, or symptoms that improve then sharply worsen: those need a doctor promptly, not the shelf. For everyone at higher risk, the yearly flu vaccine remains the one genuine prevention on offer.
If you are buying a thermometer
A basic digital stick thermometer is accurate and costs a few dollars. Forehead scanners are fine for quick checks on children; ear thermometers need good technique to read true.

Plain saline rinses are safe, drug-free and genuinely effective for blocked noses and allergy season, on their own or alongside other treatments.
