- Frequently Asked Questions
If you’re comparing Peri-Colace vs Senokot-S vs Colace 2-in-1, start with the active ingredients. The matching dual-action tablet formulas use the same two active ingredients: Docusate Sodium 50 mg and Sennosides 8.6 mg. Docusate sodium is the stool softener, and sennosides are the stimulant laxative.
So even though the names and packaging look different, these products are built around the same stool softener plus laxative combination. Peri-Colace, Senokot-S, and Colace 2-in-1 are all common brand-name options shoppers compare when they’re looking for this type of dual-action constipation relief.
The same idea applies to generics. Rugby Stimulant Laxative Plus Stool Softener, Rugby Senexon-S, Geri-Care Senna-Plus, and Health Star Senna-Plus may have different labels, but they’re all products shoppers may see in this same formula category. This guide helps you choose the right option if your usual Rugby or Geri-Care version is hard to find. For docusate-only options, see our Colace Generic Alternatives guide.
⚠️ June 2026 Supply Snapshot: Same Formula, Different Availability
Quick Summary: These products use the same Docusate Sodium 50 mg / Sennosides 8.6 mg active ingredient combination, but current availability is different by label. Health Star Senna-Plus is the preferred stable option. Rugby Senexon-S is the stable Rugby-labeled option. Rugby Stimulant Laxative Plus Stool Softener and Geri-Care Senna-Plus are intermittent right now.

Peri-Colace vs Senokot-S vs Colace 2-in-1: Are They the Same?
Peri-Colace, Senokot-S, and Colace 2-in-1 use the same active ingredients and strengths: Docusate Sodium 50 mg and Sennosides 8.6 mg. In plain English, they are three different brand-name versions of the same type of dual-action constipation medicine: a stool softener plus a stimulant laxative.
The main differences are the brand name, packaging, tablet appearance, inactive ingredients, price, and availability. If you’re comparing these products, check the Drug Facts label and look for Docusate Sodium 50 mg plus Sennosides 8.6 mg.
Do not confuse these products with plain Colace. Plain Colace is docusate-only. Colace 2-in-1 includes both docusate sodium and sennosides, which is why it belongs in the same comparison as Peri-Colace and Senokot-S.
Joe’s Translation: Peri-Colace vs Senokot-S vs Colace 2-in-1
- The Formula: Docusate Sodium 50 mg plus Sennosides 8.6 mg. One ingredient is the stool softener; the other is the stimulant laxative.
- Plain English: Peri-Colace, Senokot-S, and Colace 2-in-1 are different brand names for the same active ingredient combination when you’re comparing the matching dual-action tablets.
- Reach for this when: You want a stool softener plus stimulant laxative combination, not a docusate-only product like plain Colace.
What Generic Should You Buy?
If you’re looking for a generic version of Peri-Colace, Senokot-S, or Colace 2-in-1, Health Star Senna-Plus is the best generic alternative. Peri-Colace, Senokot-S, and Colace 2-in-1 all use the same active ingredients and strengths: Docusate Sodium 50 mg and Sennosides 8.6 mg.
That means the smartest generic comparison is not the brand name on the front of the package, but the Drug Facts label. Health Star Senna-Plus gives you the same Docusate Sodium 50 mg / Sennosides 8.6 mg active ingredient combination in a stable, high-value generic option.

View ProductRugby Stimulant Laxative Plus vs Rugby Senexon-S
Rugby Stimulant Laxative Plus Stool Softener and Rugby Senexon-S can confuse shoppers because the names sound very different. Both are Rugby-labeled products in the same active ingredient category: Docusate Sodium 50 mg plus Sennosides 8.6 mg.
The practical difference right now is supply. Rugby Stimulant Laxative Plus Stool Softener has intermittent supply, so we recommend Rugby Senexon-S if you want to stay with a Rugby-labeled product.
Health Star Senna-Plus vs Geri-Care Senna-Plus
Health Star Senna-Plus and Geri-Care Senna-Plus are the same product made by the same company, with different front-label branding. Both use the same active ingredient combination: Docusate Sodium 50 mg and Sennosides 8.6 mg.
This can confuse shoppers because one listing may say Geri-Care Senna-Plus while another says Health Star Senna-Plus. The important thing is that you are still looking at the same Senna-Plus product and the same stool softener plus stimulant laxative formula.
The practical difference right now is availability. Geri-Care Senna-Plus has intermittent supply, so we recommend Health Star Senna-Plus as the stable option. If you were looking for Geri-Care Senna-Plus, Health Star Senna-Plus is the best available replacement.
Plain Colace vs Colace 2-in-1 vs Peri-Colace: Do Not Mix These Up
The biggest mistake in this category is confusing plain Colace with Colace 2-in-1. They are not the same formula.
| Product Type | Active Ingredient Lane | What It Means |
|---|---|---|
| Plain Colace | Docusate Sodium only | Stool softener only |
| Colace 2-in-1 & Peri-Colace | Docusate Sodium + Sennosides | Stool softener plus stimulant laxative |
If you need a docusate-only stool softener, use our Colace Generic Alternatives guide instead. If you need the Peri-Colace / Senokot-S / Colace 2-in-1 formula lane, look for both Docusate Sodium 50 mg and Sennosides 8.6 mg on the Drug Facts label.
Active vs. Inactive Ingredients
Health Star Senna-Plus, Geri-Care Senna-Plus, Rugby Senexon-S, and Rugby Stimulant Laxative Plus Stool Softener all use the same active ingredients and strengths: Docusate Sodium 50 mg and Sennosides 8.6 mg. The difference is usually the front label, tablet color, packaging, supply, and inactive ingredients.
If you have sensitivities to dyes, starches, preservatives, coatings, or other inactive ingredients, this section can help you compare the options more easily. Always check the Drug Facts label on the exact bottle you receive, because inactive ingredients can change by manufacturer, lot, or packaging version.
| Product | Active Ingredients | Inactive Ingredients | Ingredient Note |
|---|---|---|---|
| Health Star Senna-Plus | Docusate Sodium 50 mg + Sennosides 8.6 mg | Cellulose, croscarmellose sodium, dicalcium phosphate, FD&C Yellow #6 Lake, hypromellose, magnesium stearate, PEG, silica, talc, titanium dioxide. | Cleanest list of the options compared here. Health Star does contain FD&C Yellow #6 Lake, so it is not dye-free, but the current ingredient list is shorter and does not list FD&C Yellow #5 (tartrazine), D&C Yellow #10, sodium benzoate, polyvinyl alcohol, or sodium lauryl sulfate. |
| Geri-Care Senna-Plus | Docusate Sodium 50 mg + Sennosides 8.6 mg | Cellulose, croscarmellose sodium, dicalcium phosphate, FD&C Yellow #6, hypromellose, magnesium stearate, PEG, sodium benzoate, stearic acid, titanium dioxide. May also contain D&C Yellow #10, FD&C Yellow #5 (tartrazine), magnesium silicate, mineral oil, silica, sodium lauryl sulfate, starch, triacetin, wax. | Same active ingredient combination as Health Star Senna-Plus, but the inactive ingredient list is longer on the label shown. |
| Rugby Senexon-S | Docusate Sodium 50 mg + Sennosides 8.6 mg | Croscarmellose sodium, D&C Yellow #10, dicalcium phosphate, FD&C Yellow #6, magnesium stearate, microcrystalline cellulose, polyethylene glycol, polyvinyl alcohol, sodium benzoate, talc, titanium dioxide. | Best option if you want to stay with a Rugby-labeled product, but it includes D&C Yellow #10 and sodium benzoate. |
| Rugby Stimulant Laxative Plus Stool Softener | Docusate Sodium 50 mg + Sennosides 8.6 mg | Croscarmellose sodium, dicalcium phosphate, FD&C Red #40, magnesium stearate, microcrystalline cellulose, polyethylene glycol, polyvinyl alcohol, sodium benzoate, talc, titanium dioxide. | Same active ingredient combination, but this version uses FD&C Red #40 and has intermittent supply. |
Best inactive-ingredient pick: If you do not need a specific front label, Health Star Senna-Plus is the cleanest choice in this comparison. It has the same Docusate Sodium 50 mg / Sennosides 8.6 mg active ingredient combination and the simplest inactive ingredient list among the options listed above.
Peri-Colace vs Senokot-S vs Colace 2-in-1: Important Label Safety Notes
Dual-action stool softener plus stimulant laxative products should be used according to the Drug Facts label. Do not assume every constipation product is interchangeable just because it is sold in the same aisle.
- Read the active ingredients: If you are trying to match Peri-Colace, Senokot-S, or Colace 2-in-1, look for both Docusate Sodium 50 mg and Sennosides 8.6 mg.
- Do not confuse it with plain Colace: Plain Colace is docusate-only and does not include sennosides.
- Follow the label: Use only as directed and do not exceed the labeled dose.
- Do not use longer than directed: Many stimulant laxative labels warn not to use for more than one week unless directed by a doctor.
- Ask a doctor: Ask before use if you have stomach pain, nausea, vomiting, a sudden change in bowel habits, ongoing constipation, or questions about whether a stimulant laxative is appropriate for you.
- Keep out of reach of children: Store all laxative products safely.
Final Verdict: Peri-Colace vs Senokot-S vs Colace 2-in-1
Peri-Colace, Senokot-S, and Colace 2-in-1 use the same active ingredients and strengths: Docusate Sodium 50 mg and Sennosides 8.6 mg. They are three different brand-name versions of the same type of dual-action constipation medicine: a stool softener plus a stimulant laxative.
If you are looking for the best generic alternative to Peri-Colace, Senokot-S, or Colace 2-in-1, choose Health Star Senna-Plus 1,000 Tablets. It gives you the same Docusate Sodium 50 mg / Sennosides 8.6 mg active ingredient combination in a stable, high-value generic option.
If you want to stay with a Rugby-labeled product, choose Rugby Senexon-S. If you were looking for Geri-Care Senna-Plus, choose Health Star Senna-Plus, which is the same product made by the same company under different front-label branding. For bulk buyers, the Health Star Senna-Plus 2-Pack is the best stock-up option.

Frequently Asked Questions
Are Peri-Colace, Senokot-S, and Colace 2-in-1 the same?
Yes. Peri-Colace, Senokot-S, and Colace 2-in-1 use the same active ingredients and strengths: Docusate Sodium 50 mg and Sennosides 8.6 mg. They are different brand-name versions of the same type of dual-action constipation medicine: a stool softener plus a stimulant laxative.

Is Colace the same as Colace 2-in-1?

What is the difference between docusate sodium and sennosides?
Docusate sodium is the stool softener. Sennosides are the stimulant laxative. In products like Peri-Colace, Senokot-S, Colace 2-in-1, and Health Star Senna-Plus, the two ingredients are combined into one dual-action tablet.
Is Rugby Senexon-S the same formula as Rugby Stimulant Laxative Plus Stool Softener?
Yes, when comparing the matching dual-action tablets, both use Docusate Sodium 50 mg and Sennosides 8.6 mg. Rugby Stimulant Laxative Plus Stool Softener has intermittent supply, so Rugby Senexon-S is the best option if you want to stay with a Rugby-labeled product.
Is Health Star Senna-Plus the same as Geri-Care Senna-Plus?
Yes. Health Star Senna-Plus and Geri-Care Senna-Plus are the same product made by the same company under different front-label branding. If you were looking for Geri-Care Senna-Plus, Health Star Senna-Plus is the best available replacement.
Does Health Star Senna-Plus have the same active ingredients as Senokot-S?
Yes. Health Star Senna-Plus uses the same active ingredient strengths as Senokot-S: Docusate Sodium 50 mg and Sennosides 8.6 mg.
Which option is best if I do not care about the brand label?
Health Star Senna-Plus 1,000 Tablets is the best default choice. If you want to stock up, the Health Star Senna-Plus 2-Pack is the best bulk value option.
Do inactive ingredients matter?
They can. The active ingredients may be the same, but inactive ingredients like dyes, fillers, coatings, and preservatives can vary by brand. If you have sensitivities to dyes or inactive ingredients, compare the Drug Facts label on the exact product you are buying.
Can I use these products every day?
Follow the Drug Facts label. Many stimulant laxative products warn not to use for more than one week unless directed by a doctor. Ask a healthcare professional if you have ongoing constipation, stomach pain, nausea, vomiting, or a sudden change in bowel habits.
