Safety concerns also apply to people who have certain allergies and to women who are pregnant or breastfeeding. Do not use Afrin for more than three days in a row, as it can make congestion worse.

- High blood pressure (hypertension)

Specific Afrin Warnings and PrecautionsSome warnings and precautions to be aware of prior to using Afrin include the following:
- Do not use Afrin more than directed or for longer than three days at a time. Rebound congestion (a worsening of congestion due to the medication) could occur (see Afrin Addiction for more information).
- Afrin can cause problems in people with glaucoma, an enlarged prostate, diabetes, hyperthyroidism, uncontrolled high blood pressure, or heart disease. If you have one of these conditions, do not use this drug without first checking with your healthcare provider.
- Afrin could potentially interact with other medications (see Afrin Drug Interactions).
- Do not share the nasal spray with anyone else, as this could spread an infection.
- Do not tip your head back when using Afrin, as this increases the chance of it running down your throat, which may increase the absorption of the medication into the bloodstream and might increase the risk of Afrin side effects.
- Afrin is considered a pregnancy Category C medication. This means that it might not be safe for use during pregnancy, although the full risks are not currently known (see Afrin and Pregnancy).
- It is unknown if Afrin passes through breast milk. Therefore, if you are breastfeeding, make sure to talk with your healthcare provider before using this medication (see Afrin and Breastfeeding).
