Answer a few simple questions about your situation to find the best osteoporosis treatment option for you.
Fosamax has been a go-to prescription for osteoporosis for over two decades. But if you’re taking it now-or considering it-you’ve probably wondered: are there better options? Maybe you’re struggling with stomach upset, or you’ve heard about rare side effects like jaw bone problems. Or maybe you just want to know what else is out there that could work just as well-or better-for your bones.
The truth is, Fosamax isn’t the only drug that helps prevent fractures in people with thinning bones. In fact, since its launch in 1995, at least six other medications have been approved for osteoporosis, each with different benefits, risks, and ways of taking them. Some are pills like Fosamax. Others are shots, infusions, or even a nasal spray. The right choice depends on your health history, how well you tolerate side effects, and what your doctor thinks will keep your bones strongest over time.
How Fosamax Works
Fosamax is the brand name for alendronate, a bisphosphonate. These drugs slow down the cells that break down bone (osteoclasts), giving bone-building cells (osteoblasts) more time to do their job. Over months and years, this helps increase bone density, especially in the spine and hip-two areas most at risk for fractures.
It’s taken as a weekly pill, first thing in the morning, with a full glass of plain water. You have to stay upright for at least 30 minutes afterward and wait before eating or drinking anything else. That’s because alendronate can irritate the esophagus if it doesn’t get washed down quickly. Many people stop taking it because of this hassle-or because they get heartburn, stomach pain, or muscle aches.
Studies show Fosamax reduces spine fractures by about 44% and hip fractures by around 25% over three years in postmenopausal women. But it’s not perfect. Long-term use (over 5 years) may increase the risk of unusual thigh bone fractures, though this is rare-about 1 in 1,000 people over 10 years.
Alternatives to Fosamax: The Main Options
Here are the most common alternatives to Fosamax, grouped by how they work and how you take them.
Risedronate (Actonel, Atelvia)
Like alendronate, risedronate is a bisphosphonate. It works the same way but is often better tolerated by people with sensitive stomachs. You can take it weekly or monthly. Atelvia is a delayed-release version taken after breakfast, which reduces the need to wait 30 minutes before eating.
It’s slightly less effective than Fosamax at reducing spine fractures-about 35% vs. 44%-but just as good at preventing hip fractures. If you had trouble with Fosamax’s strict dosing rules, risedronate might be easier to stick with.
Ibandronate (Boniva)
Boniva comes as a monthly pill or a quarterly IV infusion. The pill version has fewer stomach side effects than Fosamax, but it’s not as strong at reducing spine fractures. The infusion, given once every three months at a clinic, avoids the digestive system entirely. That’s a big plus if you have GERD, esophagitis, or just hate swallowing pills.
Studies show Boniva reduces spine fractures by 50% over three years-slightly better than Fosamax. But it doesn’t show the same level of hip fracture protection, so it’s not always the first pick for people with very low hip bone density.
Zoledronic Acid (Reclast, Aclasta)
This is a once-a-year IV infusion. You get it in a doctor’s office over 15 to 30 minutes. No pills. No fasting. No waiting to eat. It’s one of the most effective osteoporosis drugs out there.
In a major 2007 study, Reclast reduced spine fractures by 70%, hip fractures by 41%, and non-spine fractures by 25% over three years. That’s better than Fosamax across the board. Side effects? Some people get flu-like symptoms for a day or two after the infusion-fever, muscle aches, fatigue. But those usually go away with acetaminophen.
It’s often recommended for people who can’t take oral meds, have trouble remembering pills, or need maximum protection after a fracture.
Denosumab (Prolia)
Prolia is a monoclonal antibody, not a bisphosphonate. It targets a different pathway in bone breakdown-RANKL-and blocks it completely. You get a shot under the skin every six months.
It’s more effective than Fosamax at increasing bone density and reducing fractures. One study showed a 68% drop in spine fractures and a 40% drop in hip fractures over three years. It’s especially helpful for people who’ve failed other treatments or have very low bone density (T-score below -3.0).
But there’s a catch: if you stop Prolia, bone loss can happen fast. That’s why you usually need to switch to another drug like a bisphosphonate if you discontinue it. Also, there’s a small risk of serious infections and skin reactions. Your doctor will monitor your calcium levels and may give you a vitamin D supplement to prevent low calcium.
Teriparatide and Abaloparatide (Forteo, Tymlos)
These are the only two osteoporosis drugs that actually build new bone instead of just slowing bone loss. They’re synthetic forms of parathyroid hormone. You give yourself a daily injection under the skin.
Forteo reduces spine fractures by 65% and non-spine fractures by 53%. Tymlos is similar but slightly more effective at increasing bone density. Both are used for severe osteoporosis-usually after other drugs have failed or if you’ve had multiple fractures.
They’re expensive. And you can only use them for up to two years total in your lifetime. After that, you usually switch to a drug like Prolia or a bisphosphonate to hold onto the gains.
Romosozumab (Evenity)
Evenity is the newest option. It’s a monthly injection for 12 months that both builds new bone and slows bone loss. It’s the only drug with this dual action.
In trials, it cut spine fractures by 73% and hip fractures by 38% over 12 months-better than any other drug tested. After the 12 months, you typically switch to a bisphosphonate or Prolia to maintain the results.
But it comes with a black box warning: increased risk of heart attack, stroke, or cardiovascular death. So it’s not for people with a history of heart disease or stroke. It’s also expensive and only approved for postmenopausal women with very high fracture risk.
Comparing All the Options
Here’s a quick look at how these drugs stack up:
| Medication | Form | Frequency | Spine Fracture Reduction | Hip Fracture Reduction | Key Pros | Key Cons |
|---|---|---|---|---|---|---|
| Fosamax (alendronate) | Pill | Weekly | 44% | 25% | Well-studied, low cost, long-term data | Strict dosing, GI side effects, rare thigh fractures |
| Risedronate (Actonel) | Pill | Weekly or monthly | 35% | 25% | Easier on stomach, flexible dosing | Less effective for spine than Fosamax |
| Ibandronate (Boniva) | Pill or IV | Monthly or quarterly | 50% | 18% | IV option avoids GI issues | Weak hip protection, pill form still causes heartburn |
| Zoledronic Acid (Reclast) | IV infusion | Yearly | 70% | 41% | Most effective, no daily pills, high compliance | Flu-like symptoms, requires clinic visit |
| Denosumab (Prolia) | Injection | Every 6 months | 68% | 40% | Very strong, no GI issues, good for kidney patients | Must continue indefinitely or switch; risk of rebound bone loss |
| Teriparatide (Forteo) | Injection | Daily | 65% | 53% | Builds new bone, best for severe cases | Only 2 years max use, expensive, daily shots |
| Romosozumab (Evenity) | Injection | Monthly x12 months | 73% | 38% | Fastest bone gain, dual action | Heart risk, only 12 months, very expensive |
Which One Is Right for You?
There’s no one-size-fits-all answer. But here’s how to think about it:
- If you’re healthy, have no stomach issues, and want the cheapest option with proven results: Fosamax still works.
- If you hate swallowing pills or get heartburn: Reclast (yearly IV) or Prolia (every 6 months shot) are better.
- If you’ve had a recent fracture and need fast, strong protection: Evenity or Forteo might be best-but only if you don’t have heart problems.
- If you’re older, have kidney issues, or can’t take oral meds: Prolia is often preferred.
- If you’re worried about long-term side effects: Risedronate or Boniva offer gentler alternatives with good results.
Your doctor will also look at your bone density score (T-score), your fracture history, your age, your kidney function, and whether you’re taking other medications. For example, if you’re on proton pump inhibitors (like omeprazole), Fosamax might not work as well-those drugs reduce stomach acid, which is needed for alendronate absorption.
What Happens If You Stop?
Stopping any osteoporosis drug without switching to another can lead to rapid bone loss. This is especially true for Prolia and Evenity. If you stop Prolia, you lose about 10% of your bone density in the first year. That’s why doctors usually plan a transition-like switching from Prolia to Reclast or Fosamax-before stopping.
With bisphosphonates like Fosamax, the drug stays in your bones for years after you stop. That’s why some people take a “drug holiday” after 5-10 years, especially if their bone density has improved and fracture risk is low. But you need to be monitored with regular scans during that time.
Non-Medication Support
No drug works alone. Calcium and vitamin D are essential. Most adults need 1,200 mg of calcium and 800-1,000 IU of vitamin D daily. If you’re not getting enough from food or sun, supplements are necessary.
Weight-bearing exercise-walking, dancing, stair climbing, resistance training-also helps strengthen bones. Avoid smoking. Limit alcohol to one drink a day. Fall-proof your home. These steps aren’t optional. They’re part of the treatment.
Frequently Asked Questions
Can I switch from Fosamax to another drug if I’m having side effects?
Yes, absolutely. Many people switch because of stomach upset, difficulty following dosing rules, or concerns about long-term use. Your doctor can help you transition safely-especially if you’re moving from a bisphosphonate to Prolia or an infusion. Never stop cold turkey without a plan.
Is Fosamax still the best choice for most people?
It’s still a solid, affordable option, especially for people with mild to moderate osteoporosis and no digestive issues. But for those with high fracture risk, poor adherence, or side effects, newer drugs like Reclast or Prolia often offer better protection and convenience.
Are there natural alternatives to Fosamax?
No. While calcium, vitamin D, and exercise support bone health, they don’t replace prescription drugs if you’ve been diagnosed with osteoporosis. Supplements like strontium or collagen peptides aren’t proven to prevent fractures. Don’t skip medication thinking a natural remedy will do the same job.
How often do I need a bone scan while on these drugs?
Most doctors recommend a DXA scan every 1-2 years while on treatment. If you’re on a bisphosphonate and doing well, you might wait 3-5 years. If you’re on Prolia or Evenity, scans are usually done after 12 months to track progress. Your doctor will adjust based on your risk level.
Can men take these drugs too?
Yes. While osteoporosis is more common in women, men over 70-or those with low testosterone, steroid use, or other risk factors-can also benefit from these medications. Reclast, Prolia, and Forteo are all approved for men. Fosamax is too, but it’s less commonly prescribed for men because they often have fewer GI symptoms with other options.
Next Steps
If you’re on Fosamax and unhappy, talk to your doctor about alternatives. Bring a list of your side effects, how often you miss doses, and what your biggest frustrations are. If you’re not on any medication yet but have low bone density, ask whether a stronger or easier option might be better for you.
Osteoporosis isn’t a quick fix. It’s a long-term condition that needs consistent care. The right drug can cut your fracture risk in half. But only if you take it-and stick with it. Don’t settle for the first option you’re given. Ask questions. Compare options. Your bones will thank you.

October 29, 2025I’ve been on Fosamax for 4 years and honestly? The morning ritual is brutal. Staying upright for 30 minutes while sipping water like a robot? I’d forget to eat lunch and just stare at the wall. Switched to Prolia last year-no more stomach pain, no more timing nonsense. Just a quick shot every six months. My bones are happier, and so am I.
Don’t let the fear of injections scare you. It’s a needle, not a prison sentence.
Anna S.
October 30, 2025People who take these drugs are just giving up on their bodies. You think calcium pills and shots fix everything? No. You’re just numbing the problem. Real bone health comes from eating real food, walking barefoot on grass, and stopping the fear-mongering pharmaceutical propaganda. Fosamax? That’s just Big Pharma’s way of keeping you dependent.
Michael Harris
October 30, 2025Anna, your ‘real food’ nonsense is dangerous. Osteoporosis isn’t a spiritual awakening-it’s a measurable loss of bone mineral density. If you think yoga and kale prevent hip fractures in women with T-scores under -3.0, you’re not helping. You’re endangering people. The data is clear: bisphosphonates and biologics reduce fracture risk by 40-70%. Skip the pseudoscience. Get your DXA scan. Take the meds.
Also, ‘walking barefoot’ doesn’t rebuild trabecular structure. That’s not magic. That’s biology.
Milind Caspar
October 31, 2025Michael, you’re correct in your clinical assessment, but you’re missing the broader systemic failure. The entire osteoporosis treatment paradigm is built on profit-driven metrics, not patient autonomy. The FDA approved Reclast and Evenity based on surrogate endpoints-bone density increases-not hard outcomes like mortality reduction. Meanwhile, the risk of atypical femoral fractures and osteonecrosis of the jaw is downplayed in patient leaflets. These are not benign drugs. They are chemical interventions with lifelong consequences.
And yet, doctors still prescribe them like aspirin. Why? Because the pharmaceutical reps bring lunch. Because the guidelines are written by consultants with ties to Amgen and Merck. Because insurance won’t cover the natural alternatives-even though vitamin K2 and magnesium have been shown in peer-reviewed studies to improve bone turnover markers.
So yes, take the shot if you must. But don’t pretend you’re not part of a system that commodifies fear.
KC Liu
November 2, 2025Oh wow. So now we’re accusing doctors of being paid by Big Pharma while simultaneously dismissing clinical trials with 10,000+ patients? You’re not a philosopher, Milind-you’re a conspiracy theorist with a thesaurus.
Let me guess: you also think vaccines cause autism and fluoride is a mind-control agent? Because this is the same logic. You cherry-pick one rare side effect, ignore the 99% who benefit, and declare the entire medical establishment corrupt.
Here’s a radical idea: maybe the reason these drugs work is because they’re scientifically tested, not because someone’s got a yacht funded by Pfizer.
Sam Tyler
November 3, 2025Both sides here are missing the point. The real issue isn’t whether Fosamax is evil or miraculous-it’s that we treat osteoporosis like a one-size-fits-all condition. It’s not. A 68-year-old woman with a hip fracture and a T-score of -3.8 needs Evenity. A 72-year-old man with kidney disease needs Prolia. A 55-year-old with mild osteopenia and no fractures? Maybe lifestyle changes + calcium + vitamin D for a year, then reassess.
But instead, we hand out prescriptions like candy because the system rewards speed over nuance. The solution isn’t rejecting meds-it’s demanding personalized, patient-centered care. Doctors need more time. Patients need better education. And we need to stop turning medical decisions into moral battles.
Also, if you’re reading this and you’re on a bisphosphonate: please, get your dental checkups. The jaw necrosis risk is real-but preventable with good oral hygiene. Don’t let fear stop you. But don’t ignore the warnings either.

November 5, 2025Sam, you’re right. I’m from India, and here, most people don’t even know what a DXA scan is. We have elders with broken hips lying on floors because they think ‘bones get weak with age’-and no one tells them it’s treatable. I’ve seen women in their 80s walk with sticks because they were too scared of ‘chemicals’ to take even a simple pill.
But I’ve also seen people on Prolia who stopped because they heard it causes ‘cancer’-and now they’re in wheelchairs. We need community health workers to explain this-not just doctors in white coats.
And yes, yes, vitamin D deficiency is epidemic here. Sunlight is free. But people work indoors. They cover up. They eat white rice. It’s not laziness. It’s poverty. We need public health campaigns, not just Reddit threads.
John Dumproff
November 5, 2025Shridhar, you just said something so important. I work in a community clinic in rural Ohio. Same thing. Elderly patients think ‘if it’s not in a pill, it’s not real medicine.’ We’ve had women refuse Reclast because ‘IVs are for cancer.’ Then they break a hip and end up in rehab for six months.
My job isn’t to push drugs. It’s to make them feel safe. I sit with them. I show them the studies. I say, ‘This isn’t about trusting pharma. It’s about trusting your future self.’
One lady told me, ‘I’d rather die than get a shot.’ Now she’s walking without a cane. She calls me every month to say thank you.
It’s not about the drug. It’s about the human connection.
Shanice Alethia
November 6, 2025OH MY GOD. I JUST FOUND OUT MY GRANDMA WAS ON FOSAMAX FOR 8 YEARS AND SHE NEVER TOLD ANYONE BECAUSE SHE WAS AFRAID OF THE JAW THING??
SHE JUST WENT TO THE DENTIST AND THEY SAID HER GUMS WERE ‘UNUSUALLY THIN’ AND SHE THOUGHT IT WAS JUST ‘AGING’??
IS THIS HAPPENING TO EVERYONE?? WHY ISN’T THIS ON THE NEWS??
MY MOM IS ON PROLIA NOW AND I’M SCARED SHE’LL LOSE HER JAW AND NO ONE WILL TELL HER UNTIL IT’S TOO LATE??
WE NEED A CLASS ACTION LAWSUIT. I’M STARTING A PETITION. #FOSAMAXJAWCRISIS
Ellen Frida
November 7, 2025the jaw thing is real but so is the fact that your bones turn to dust if you dont take something... its like choosing between a slow death by crumbling or a quick death by dentist horror... i think i'd rather have the jaw thing tbh? at least then you get to see a cool dentist who goes 'oh honey you're a medical mystery' and takes x-rays of your face like you're a dragon from a fantasy novel
also why is no one talking about how evenity makes you feel like you got hit by a truck for 2 days? i cried after my first shot and my cat stared at me like i betrayed her
Dylan Kane
November 9, 2025Ellen, I’m not even mad. I’m impressed. That was the most honest thing I’ve read all week.
Yes, Evenity feels like the flu got a PhD in revenge. Yes, your cat will judge you. Yes, your jaw might one day become a museum exhibit.
But here’s the thing: I broke my hip at 62. I was in a wheelchair for three months. I couldn’t hug my grandkids. I didn’t care about the side effects then. I cared about standing up again.
So yeah-take the shot. Cry. Let the cat side-eye you. Your bones don’t care about your drama. They just want to hold you up.
William Cuthbertson
November 10, 2025There’s a quiet tragedy here, and it’s not the drugs-it’s the silence. We live in a world where we’re told to ‘take charge of our health,’ yet when we do-when we follow the science, swallow the pill, show up for the infusion-we’re met with either pharmaceutical propaganda or anti-medical dogma. No middle ground. No nuance. Just fear or faith.
But bone isn’t ideology. It’s tissue. It responds to load, to nutrients, to chemistry. It doesn’t care if you’re a ‘naturalist’ or a ‘pharma zombie.’ It just wants what it needs.
Perhaps the real revolution isn’t in choosing one drug over another-but in reclaiming our relationship with medicine: not as enemies, not as gods, but as partners in a long, quiet process of healing.
And yes-your cat still loves you. Even if you cry after shots. Especially then.
Yaseen Muhammad
November 10, 2025William, that’s beautiful. I’m a nurse in Mumbai. I see grandmothers who walk 3 miles to the clinic just to get their vitamin D. They don’t know the names of the drugs. They just know: ‘If I don’t do this, I won’t hold my great-grandchild again.’
So I tell them: ‘This isn’t about trusting a company. It’s about trusting your own body’s will to live.’
And then I hand them the pill. Or the shot. Or the walking cane.
It’s not perfect. But it’s human.
Lugene Blair
November 12, 2025Yaseen, you just gave me chills. I’m a physical therapist. I’ve seen women who couldn’t stand up after a fracture-then, six months after starting Reclast and doing balance exercises three times a week-they’re dancing at their granddaughter’s wedding.
It’s not magic. It’s science. It’s sweat. It’s support.
So if you’re reading this and you’re scared? Start small. One step. One pill. One shot. One day.
You don’t have to be brave. Just show up.
Your future self is already thanking you.
