Does 7.5 mg mirtazapine cause weight gain?

I recently started taking 7.5 mg of Mirtazapine for my sleep issues. I'm concerned about weight gain as a side effect. Can this dosage of mirtazapine cause noticeable weight gain, or is it less common at 7.5 mg?

I was so anxious when my doctor suggested this dose because I constantly worry about side effects. Honestly, lower doses like 7.5 mg actually tend to increase appetite and make you sleepy, which can lead to some weight gain. Try to keep healthy snacks nearby so you don't overeat when the cravings hit.

Yes, mirtazapine is known for increasing appetite, even at 7.5 mg. If your doctor allows, starting a daily 45-minute brisk walk and staying active can really help manage that extra calorie intake. It is all about burning what you eat.

Look, boss, 7.5 mg mirtazapine is a small dose but it definitely boosts your appetite and makes you crave sweets. If you are taking it, be mindful of what you eat and don't panic. Just talk to your doctor if you see the weight climbing too fast.

Mirtazapine is highly antihistaminic at lower doses like 7.5 mg, which is why it causes sedation and increased appetite. Many in our community have reported weight gain on it. I suggest keeping a food journal and discussing alternatives with your doctor if it becomes a problem.

I really struggled emotionally when I started gaining weight on this dose, as it felt like a setback. It is a very real side effect, and your feelings about it are completely valid. Please speak to your therapist or doctor; they can help find a balance for your mental and physical health.

Weight gain is indeed a very common side effect of 7.5 mg mirtazapine. Please don't stop the medication abruptly on your own, as that can be unsafe. Consult your prescribing doctor to monitor your metabolic health safely.
