Catapres (Clonidine) for anxiety: Facts, Uses, and Side-Effects

What is Catapres?

Catapres (clonidine hydrochloride) decreases anxiety attacks and psychiatric symptoms—as such, it is often prescribed for panic disorder and/or other mental health conditions. Panic disorder (PD) is a common anxiety disorder that may severely affect a person's day-to-day life as they begin to avoid certain places or situations to prevent panic attacks.

The goal with treatment is to reduce the severity and frequency of panic attacks so that it doesn't interfere with a person's personal, work, academic, or social lives. The medication is also used to treat high blood pressure (hypertension) outside of the mental health context.

How to use Catapres

Catapres tablets are taken by mouth, with or without food, usually twice, once in the morning and once at bedtime. The larger dose is typically taken at bedtime to decrease the risk of side effects.

If you forget a dose, take it as soon as you remember it, unless it's close to another scheduled dose. Do not double dose to compensate for missing an earlier one.

As with most drugs, please take the medication as instructed, even if you feel well. It's important to not stop without consulting your medical professional first. Withdrawal side effects can range from nervousness, agitation, headache, and shaking, leading up to fatality.

After taking Catapres for some time, a dosage adjustment or pairing with another medication might be necessary since the medicine's effectiveness may be reduced as your body adjusts.

The medication will not cure panic disorder but help you manage your symptoms.
