Pro-tip: ask the pharmacist what strength/forms they have and then bring that info back to your doctor and have them write for what’s available. If you usually take 20mg and the pharmacy doesn’t have it but they do have 10 mg in stock, then your doctor could write for you to have 60 count of 10 mg, taking 2 per day, instead of 30 count of 20 mg.

The pharmacy cannot make the substitute on their own - they have to fill the prescription as written so this only works if your doctor writes for what the pharmacy has in stock.

Also, your insurance may choose to act stupid about it, as they do with basically any medication changes at this point. Cash price on GoodRX isn’t bad though.
