Does modafinil cause weight gain?

I've been prescribed modafinil to help with my daytime sleepiness. I'm trying to maintain my current weight, so I'm a bit concerned about side effects. Does modafinil cause weight gain?

Don't worry, I actually panicked about this too when starting. But it typically does the opposite—it suppresses your appetite, so weight gain is very unlikely.

May you find peace and good health. It generally doesn't cause weight gain, but remember to eat your meals on time even if you don't feel very hungry.

Actually yaar, it makes you forget about food because you are so focused. So weight gain is definitely not a common issue with this one.

Haan na, it actually reduces appetite quite a bit. I used to forget to eat my lunch sometimes, so weight gain is rare with this.

Modafinil is a stimulant and typically acts as an appetite suppressant, so most people experience weight loss rather than gain. However, consult your doctor if you notice any unusual metabolic changes.

It won't cause weight gain, but make sure you set an alarm for your meals. Since it keeps you alert and busy, you might skip food, which isn't good for your health.
