Does cetirizine cause weight gain?

I've been taking Cetirizine daily for my seasonal allergies, and it's been really helpful. However, I've also noticed a steady weight gain recently. Does Cetirizine cause weight gain as a side effect?

While Cetirizine is a common antihistamine, some studies do suggest that long-term use can slightly increase appetite, leading to weight gain. However, if you are experiencing sudden or unexplained weight changes, please consult your doctor to rule out other issues.

Actually yaar, I have been taking Cetirizine for my dust allergy for months. It makes me feel super drowsy, and when you are sleepy, you tend to move less and munch more. That's probably why people feel they are gaining weight!

At my age, managing high blood pressure and daily allergies requires a strict lifestyle. While Cetirizine might cause a little drowsiness or slight weight gain if taken daily, keeping active and eating a low-salt diet helps manage both issues well.

Cetirizine is a very cheap allergy medicine, but if you are worried about side effects like weight gain, it's better to consult a doctor. Spending 300 rupees on a doctor's advice is much better than buying expensive alternative allergy treatments blindly.

I used to take allergy pills daily and noticed some weight gain and constant bloating. I switched to steam inhalation with a drop of eucalyptus oil and drinking warm ginger water daily. It naturally cleared my nose so I didn't need to take Cetirizine so often.

Do not let minor worries about weight gain disturb your inner peace, dear. If the medicine helps you breathe and live comfortably, take it with a positive mind. Just eat clean, fresh foods and stay active to keep your body in harmony.

When I went to Medanta for my sinus issues, the specialist told me that antihistamines like Cetirizine can sometimes block histamine receptors that control hunger, causing you to eat more. You should ask your doctor clearly if they can prescribe a non-drowsy alternative.
