Don’t ask doctors for antibiotics for the common cold

It costs nothing and can even save you money on medicine.

A Cochrane systematic review pooled data from 6 randomized trials involving 1,147 participants. When comparing antibiotic use to placebo for treating colds, there was no significant difference in the proportion of people who did not recover or whose symptoms persisted (RR 0.83, 95% CI 0.60–1.14, no statistically significant difference). The risk of adverse reactions was 1.8 times higher than in the placebo group (95% CI 1.01–3.21). For adults specifically, this risk was 2.62 times higher (1.32–5.18), while no increase was observed in children (RR 0.91, 0.51–1.63). For acute purulent rhinitis where nasal discharge with pus lasts less than 10 days, antibiotics also showed no clear benefit (RR 0.73, 0.47–1.13). However, the risk of adverse reactions rose by roughly 46% (RR 1.46, 1.10–1.94). The authors concluded that routine use of antibiotics is not recommended for either of these conditions.

This edition was issued again in 2025, and the abstract states that the literature search runs through 2013. In China antibiotics are prescription drugs. A pharmacy has to sell them against a prescription. Do not take leftover antibiotics at home on your own either. The benefit is rated moderate, as a judgment: what it prevents is adverse reactions, not death. Also do not ask for an intravenous drip for a cold. See section 6, item 35 (asking for an intravenous drip for a cold or a fever).
