Does klonopin make you gain weight or not? The side affects say both?

Yes, absolutely. It increases appetite. It also seems to slow metabolism. I have been on it for sleep seizures several years. It works well, but I have gained 35 pounds and am now overweight. Tests show thyroid levels are fine. I teach dance and am otherwise in good shape. There is no junk food in my diet but I am hungrier more often and it takes more food for me to feel full.

Most common side effects are:

Clumsiness or unsteadiness; constipation; cough; dizziness; drowsiness; dry mouth; headache; increased saliva production; lightheadedness; loss of appetite; muscle aches; nervousness; runny nose; tiredness.

Severe side effects occur when using Klonopin:

Severe allergic reactions (rash; hives; itching; difficulty breathing; tightness in the chest; swelling of the mouth, face, lips, or tongue); behavior changes; blurred vision or other vision changes; change in the amount of urine produced; confusion; dark urine; fever, chills, or sore throat; hallucinations; hostility; irregular heartbeat; memory loss or problems; mental or mood changes (eg, agitation, aggression, anxiety; depression, hostility, irritability); new or worsening seizures; painful menstrual periods; painful urination; severe drowsiness; severe or persistent tiredness or weakness; shortness of breath; slow or shallow breathing; slurred speech or other speech problems; suicidal thoughts or actions; tremor; unusual bruising or bleeding; yellowing of the skin or eyes.

Since the common side effect is loss of appetite, it would not lead to weight gain.
