How long does it take for this medicine to take effect?

The onset of action for nasal sprays can vary depending on the active ingredient(s). Decongestant nasal sprays may work within minutes to reduce nasal congestion, while corticosteroid nasal sprays may take several hours to days to achieve their full effect, especially for allergy symptoms. Antihistamine nasal sprays typically begin to relieve symptoms within 15 minutes to an hour.

How long do the effects of this medicine last?

The duration of effects also varies:

Decongestant nasal sprays typically provide relief for up to 12 hours but should not be used for more than a few days consecutively to avoid rebound congestion.
Corticosteroid nasal sprays have effects that can last 24 hours, supporting once-daily dosing for chronic conditions like allergic rhinitis.
Antihistamine nasal sprays may offer relief for up to 12 hours.

Is it safe to consume alcohol while taking this medicine?

While nasal sprays generally have localized effects with minimal systemic absorption, consuming alcohol doesn't directly interact with the efficacy of nasal sprays. However, alcohol can exacerbate certain conditions like sinus congestion and should be consumed in moderation.

Is this a habit forming medicine?

Nasal sprays, particularly decongestant types, can lead to rebound congestion if used for longer than recommended (usually not more than 3-5 days). This is not a traditional form of physical or psychological dependence but can result in a cycle of continued use to relieve persistent congestion. Corticosteroid and antihistamine nasal sprays do not have this habit-forming potential.

Can this medicine be taken during pregnancy?

The safety of using nasal sprays during pregnancy depends on the active ingredient. Many are classified as Category B or C, indicating that there's no evidence of harm to the fetus in animal studies but adequate human studies are lacking. It's essential for pregnant women to consult healthcare providers before using any medication, including nasal sprays.

Can this medicine be taken while breast-feeding?

Small amounts of medication from nasal sprays can be excreted in breast milk, but due to their local application and minimal systemic absorption, they are generally considered safe. However, nursing mothers should consult with a healthcare provider for personalized advice, considering the specific active ingredients in the nasal spray.


This medication is used for temporary relief of congestion in the nose caused by various conditions including the common cold, sinusitis, hay fever, and allergies. It works by narrowing the blood vessels in the nose area, reducing swelling and congestion.

How to use Wal-Four Spray, Non-Aerosol

Use this medication in the nose as directed. Follow all directions on the product package, or use as directed by your doctor. If you have any questions, ask your doctor or pharmacist.

While keeping your head upright, place the spray tip into the open nostril. Spray the medication into the open nostril as you breathe in through your nose. Sniff hard a few times to be sure the medication reaches deep into the nose. Repeat these steps for the other nostril if needed.

Avoid spraying the medication into your eyes or onto the middle of the inside of your nose (nasal septum).

Rinse the spray tip with hot water or wipe with a clean tissue after each use. Make sure that water does not get inside the container. Replace cap after each use.

This medication provides only temporary relief. Do not use more often, use more sprays, or use longer than directed because doing so may increase the risk of side effects.
