Mucus Relief Guaifenesin 600 mg Extended-Release Tablets (200 Ct, 12-Hour)

A2Z Smartshop focuses on comparison and choice—helping you weigh formats, dosing styles, and trade-offs before you click through to a marketplace listing. This page explains how a 12-hour extended-release guaifenesin tablet differs from standard expectorants, and who that difference actually benefits.

What this product is (at a glance)

This listing is for a high-count expectorant option: guaifenesin 600 mg per tablet in a 12-hour extended-release format, supplied as a 200-tablet bottle.

Extended-release guaifenesin is commonly chosen to help loosen and thin chest mucus while reducing how often doses are taken during the day. As with all OTC medicines, the Drug Facts panel on the package images is the definitive source for ingredients, directions, warnings, and age suitability.

Who this may be for

• You want fewer daily doses compared with standard-release expectorants.
• You need ongoing mucus relief and prefer a steady, longer-lasting format.
• You are comparing cost per tablet and want a larger bottle for regular use.
• You specifically want a single-ingredient product without decongestants or pain relievers.

Who this is NOT for

• Anyone who needs nasal/sinus decongestion—guaifenesin targets chest mucus, not nasal blockage.
• Shoppers who prefer short-acting relief they can time very precisely.
• People who have trouble swallowing larger tablets, which extended-release formats can be.
• Buyers who may not use a 200-count supply before the expiry date.

Trade-offs to understand before you buy

1) Extended-release convenience vs. flexibility

The main advantage of a 12-hour tablet is convenience—fewer doses across the day. The trade-off is flexibility: once taken, you cannot easily adjust timing or dose the way you might with shorter-acting tablets.

2) Tablet size and swallowability

Extended-release guaifenesin tablets are often larger than standard versions. If tablet size matters to you, check the listing photos carefully or confirm with the seller before buying.

3) Bulk quantity and expiry risk

A 200-count bottle can be good value only if the expiry date aligns with your usage. On marketplace listings, always verify expiry visibility and avoid assumptions based on stock photos alone.

4) Marketplace quality signals

For OTC medicines on eBay, value depends on new, sealed packaging, clear labeling, and an intact tamper-evident seal. Confirm these details in the photos and description, and review seller feedback and return terms.
