How dosage affects Guanfacine ER price
For most medications including Guanfacine ER, higher dose = higher price. This is because:
- More active pharmaceutical ingredient (API) per tablet — the API is usually the most expensive raw material.
- Lower-volume manufacturing runs for less common strengths.
- Higher patient demand for certain strengths shifts pricing.
Key dosing principles for Guanfacine ER

Talk to your doctor before changing your Guanfacine ER dose
Cost should never be a reason to skip doses, split tablets without approval, or stop Guanfacine ER on your own. Many prescribers will adjust dose or formulation to help you afford the medication — they want you on therapy.
If cost is the issue: mention it to your prescriber. They may switch you to a different strength, generic equivalent, or 90-day supply that fits your budget. ScriptUnlock can help you find Guanfacine ER at the lowest cash price near you.
