Question 1

How soon after using Jext should I feel better?

Accepted Answer

Most people notice improvement in breathing, swelling, and dizziness within 1‑5 minutes. Full effect is seen around 5‑15 minutes. If no improvement after 5‑10 minutes, use a second Jext.

Question 2

Can Jext wear off before I reach hospital?

Accepted Answer

Yes, the effect lasts 20‑30 minutes. That's why you must call 999 immediately – paramedics can give additional adrenaline and other treatments if needed.

Question 3

How long does adrenaline stay in your system after Jext?

Accepted Answer

Adrenaline itself is cleared from blood within 10‑15 minutes (half‑life 2‑3 minutes). Inactive metabolites may be detected in urine for up to 24 hours.

Question 4

What if I need a second dose – how long should I wait?

Accepted Answer

If symptoms are not improving or are worsening after 5‑10 minutes, administer a second Jext using a new pen. Do not delay seeking emergency help.

Question 5

Does Jext work faster if injected into a vein?

Accepted Answer

No – Jext is designed for intramuscular use only. Intravenous injection requires controlled hospital settings due to risk of dangerous arrhythmias. Always inject into muscle.
