Alternatives to Bonjesta If You Can't Fill Your Prescription

When You Can't Get Bonjesta, You Still Have Options

Morning sickness doesn't wait for pharmacy stock or insurance approvals. If you've been prescribed Bonjesta but can't find it at your pharmacy, can't afford the cash price, or your insurance won't cover it, you need to know what alternatives are available.

The good news: there are several safe, effective options for treating nausea and vomiting during pregnancy. Some are prescription medications, and some you can find over the counter. Let's walk through them.

What Is Bonjesta and How Does It Work?

Bonjesta is a prescription extended-release tablet containing 20 mg Doxylamine Succinate (an antihistamine) and 20 mg Pyridoxine Hydrochloride (vitamin B6). It's FDA-approved specifically for nausea and vomiting of pregnancy (NVP) in women who don't get enough relief from diet and lifestyle changes.

The extended-release design provides both immediate and sustained relief. Part of the medication starts working quickly, while the rest is released slowly over several hours. This makes Bonjesta convenient — most women take just 1-2 tablets per day.

Alternative #1: Diclegis (or Generic Doxylamine/Pyridoxine)

Diclegis is the closest alternative to Bonjesta. It contains the same two active ingredients — Doxylamine Succinate and Pyridoxine Hydrochloride — but at a lower dose of 10 mg/10 mg per tablet in a delayed-release (not extended-release) formulation.

Key differences from Bonjesta:

• Dosing: Diclegis is typically taken as 2 tablets at bedtime, with the option to add 1 tablet in the morning and 1 at midday if needed (up to 4 tablets daily). Bonjesta maxes out at 2 tablets per day.
• Generic available: Unlike Bonjesta, Diclegis has a generic version (Doxylamine/Pyridoxine delayed-release tablets). This makes it much more affordable and easier to find at pharmacies.
• Cost: Generic Diclegis can cost as little as $30-$60 for 60 tablets, compared to $480+ for brand-name Bonjesta.

For many women, Diclegis or its generic provides similar relief at a fraction of the cost. Ask your OB/GYN if switching makes sense for you.

Alternative #2: Over-the-Counter Doxylamine + Vitamin B6

Before prescription options like Bonjesta and Diclegis existed, doctors commonly recommended the OTC combination of Doxylamine Succinate (Unisom SleepTabs) and vitamin B6 (Pyridoxine) supplements. This remains the most affordable option and is often the first-line recommendation from the American College of Obstetricians and Gynecologists (ACOG).

How to use it:

• Take 25 mg of Doxylamine (one Unisom SleepTab — make sure it's the Doxylamine version, not Diphenhydramine) at bedtime
• Take 25 mg of vitamin B6 up to three times daily
• Your doctor can help you adjust the dosing based on your symptoms

Important: Make sure you're buying Unisom SleepTabs (Doxylamine Succinate), not Unisom SleepGels (Diphenhydramine). They are different medications despite having similar names.

Cost: Typically under $15 for both products combined at most pharmacies and grocery stores.

Alternative #3: Ondansetron (Zofran)

Ondansetron, sold under the brand name Zofran, is a powerful anti-nausea medication originally developed for chemotherapy-induced nausea. It works differently from Bonjesta — it blocks serotonin (5-HT3) receptors in the brain that trigger nausea and vomiting.

Key facts:

• Ondansetron is used off-label for pregnancy nausea (it's not FDA-approved specifically for NVP)
• It's typically reserved for moderate-to-severe morning sickness that doesn't respond to Doxylamine/B6 combinations
• Available as tablets, orally disintegrating tablets, and liquid
• Generic Ondansetron is widely available and affordable — often under $15 for a 30-day supply with a coupon

Talk to your doctor about the benefits and risks. Some studies have raised questions about Ondansetron use in early pregnancy, though major medical organizations still consider it a reasonable option when first-line treatments fail.

Alternative #4: Promethazine (Phenergan)

Promethazine is a phenothiazine antiemetic that has been used for decades to treat nausea and vomiting, including during pregnancy. Like Ondansetron, it's used off-label for NVP.

Key facts:

• Available as tablets, suppositories, and injection
• Can cause significant drowsiness — even more than Bonjesta
• Generic versions are widely available and affordable (typically under $10 for a 30-day supply)
• Often used when other medications haven't provided adequate relief

Alternative #5: Metoclopramide (Reglan)

Metoclopramide is a dopamine antagonist that helps with nausea by increasing stomach motility and blocking nausea signals in the brain. It's another off-label option for pregnancy nausea.

Key facts:

• Usually reserved for more severe NVP or hyperemesis gravidarum
• Can cause side effects including drowsiness, restlessness, and (rarely) movement disorders
• Generic is widely available — typically under $10 for a 30-day supply

How to Decide Which Alternative Is Right for You

The best alternative depends on several factors:

• Severity of your symptoms: Mild-to-moderate NVP often responds well to OTC Doxylamine + B6 or generic Diclegis. Severe NVP may require Ondansetron or Metoclopramide.
• Your budget: OTC Doxylamine + B6 is the most affordable option (under $15). Generic Diclegis and generic Ondansetron are also budget-friendly.
• Side effect tolerance: All of these medications can cause drowsiness, but the degree varies. Promethazine tends to be the most sedating.
• Your doctor's recommendation: Every pregnancy is different. Your OB/GYN knows your medical history and can guide you to the safest option.

Final Thoughts

Not being able to fill your Bonjesta prescription is frustrating, but it doesn't mean you have to suffer through morning sickness without help. From generic Diclegis to affordable OTC options, there are several proven alternatives that can provide real relief.

Talk to your doctor about which option makes the most sense for your situation, and use Medfinder to find any of these medications in stock near you.
