Aristada Initio Side Effects

Seek urgent medical attention if you notice signs of an allergic response, such as hives, breathing difficulties, or swelling in your face, lips, tongue, or throat.

Extended use or elevated doses of aripiprazole might trigger a significant movement condition that could be permanent. The likelihood of developing this issue grows with prolonged use of Aristada Initio, especially among women and elderly individuals.

During treatment with Aristada Initio, you may experience heightened sexual impulses, a strong desire to gamble, or other powerful urges. Consult your physician if these emerge.

How is Aristada Initio Administered?

If you’re already taking another antipsychotic drug, you may need to temporarily continue it. Don’t adjust your dosage or timing without your doctor’s input.

If you’re new to Aristada Initio, you might need to ingest it orally (via tablet or liquid) before your initial injection.

You could be required to take Aristada Initio by mouth for up to three weeks post-first injection. Follow your doctor’s dosage directions meticulously.

Aristada Initio is delivered through a muscular injection. A medical professional will administer this shot every 4 to 8 weeks. Your doctor might periodically modify your dose and injection timing.

Your blood sugar will require regular monitoring, and additional medical evaluations may be necessary.
