Are cold and flu tablets toxic to cats?
Severe
No — cold and flu tablets are doubly dangerous for cats. Decongestants like phenylephrine race the heart and cause agitation, and most Indian cold tablets (Sinarest, Vicks Action 500) also contain paracetamol, which is deadly to cats. Go to a vet now with the strip.
Why severe: Decongestants overstimulate the heart and brain, and most Indian cold tablets also contain paracetamol — deadly to cats.

What counts
Cold, flu, sinus and allergy tablets, capsules and syrups with a decongestant; decongestant nasal sprays and eye drops (a chewed bottle is enough).
What's in it
Decongestants — phenylephrine and pseudoephedrine in tablets, xylometazoline and oxymetazoline in nasal sprays — tighten blood vessels and stimulate the heart and brain. Combination tablets add paracetamol and antihistamines (Merck).

What to do — now
Go to a vet now. Take the strip — the vet needs every ingredient, especially paracetamol.
- Don't make your cat vomit at home unless a vet tells you to.
- Never give a cat a human cold tablet, syrup or nasal spray.
Where Indian cats meet it
Cold tablets are bought over the counter and kept in handbags and bedside drawers through winter and the monsoon — and a sneezing cat is sometimes given a little of the family's cold medicine.
Myth or fact
Myth“A bit of a cold tablet will help a sneezing cat”
FactMost cold tablets mix paracetamol with a decongestant, and 'even small amounts of these formulations can be poisonous' (VCA). Cat flu needs a vet.
Cat-safe swap: Ask your vet — a sneezing cat needs cat medicines.
