Actonel 35 12-Week Is a Once-Weekly Osteoporosis Medication

Actonel 35 12-Week is a prescription bisphosphonate medication containing Risedronate Sodium 35 mg, taken as one tablet per week for 12 weeks to treat and prevent osteoporosis.

If you've been diagnosed with osteoporosis — or your doctor is trying to prevent it — there's a good chance bisphosphonates have come up. Actonel 35 12-Week is one of the most established options in this drug class, and while newer treatments have appeared over the years, Risedronate remains a front-line choice for bone health. Here's everything you need to know.

What Is Actonel 35 12-Week?

Actonel is the brand name for Risedronate Sodium, a bisphosphonate drug. It's manufactured by Allergan, now part of AbbVie. The "35" refers to the 35 mg tablet strength, and "12-Week" refers to the dispensing format — a blister pack containing 12 tablets, one for each week of a 12-week treatment cycle.

Risedronate belongs to a class of drugs called bisphosphonates, which work by slowing down the cells that break down bone (osteoclasts). This helps your bones stay denser and stronger over time. For a plain-English explanation of how this works, see our article on how Actonel 35 12-Week works.

Risedronate is also sold under the brand name Atelvia (a delayed-release version taken after breakfast). Generic Risedronate Sodium is widely available and significantly cheaper than brand-name Actonel.

Actonel is not a controlled substance. It does not have a DEA schedule and has no abuse potential.

What Is Actonel 35 12-Week Used For?

The FDA has approved Risedronate for several indications:

• Treatment and prevention of postmenopausal osteoporosis — The most common use. Helps prevent fractures in women after menopause.
• Treatment of osteoporosis in men — Men get osteoporosis too, and Risedronate is approved for this.
• Treatment and prevention of glucocorticoid-induced osteoporosis — For patients taking long-term steroids like Prednisone, which can weaken bones.
• Treatment of Paget's disease of bone — A condition where bones grow too large and become weak (typically treated with the 30 mg daily dose, not the 35 mg weekly dose).

How Is Actonel 35 12-Week Taken?

The dosing instructions for Actonel 35 12-Week are very specific — and following them correctly is important for both effectiveness and safety:

1. Take it first thing in the morning, before eating or drinking anything other than plain water.
2. Swallow the tablet whole with at least 6-8 ounces (a full glass) of plain water. Do not use mineral water, coffee, juice, or any other beverage.
3. Do not crush, chew, or suck on the tablet.
4. Stay upright — sit or stand — for at least 30 minutes after taking the tablet. Do not lie down.
5. Wait at least 30 minutes before eating, drinking anything else, or taking other medications (especially calcium, antacids, or iron supplements).
6. Take one tablet per week, on the same day each week, for 12 weeks.

These instructions exist because Risedronate can irritate the esophagus if it doesn't pass quickly to the stomach. Taking it correctly prevents this and ensures proper absorption.

Risedronate is also available in other dosing schedules: 5 mg daily, 75 mg on two consecutive days per month, and 150 mg once monthly. Your doctor will choose the schedule that works best for you.

Who Should Not Take Actonel 35 12-Week?

Actonel is not right for everyone. You should not take it if you have:

• Low blood calcium (hypocalcemia) — This must be corrected before starting treatment.
• Esophageal problems — Conditions like strictures or achalasia that prevent the tablet from passing to your stomach quickly.
• Inability to sit upright for 30 minutes — If you cannot stay upright after taking the tablet, this medication is not safe for you.
• Severe kidney disease — Creatinine clearance below 30 mL/min. Your doctor will test your kidney function.
• Allergy to Risedronate — If you've had a reaction to this drug or any of its ingredients.
