Where to Buy a Menstrual Sponge (Pharmacy, Online) and How to Choose Well

Can you buy a menstrual sponge at your local pharmacy? Almost always the answer is no, even though that sounds counterintuitive for an intimate hygiene product. The menstrual sponge at the pharmacy is still a rare find: few chains stock it, and when you do find one, the price is usually higher than buying it directly from source. Here’s where to actually buy it, what to expect from each channel, and how to choose the right sponge so it isn’t money wasted.

Is the menstrual sponge sold in pharmacies?

The reality is that the natural sea sponge barely has a presence in the pharmacy channel in Spain, unlike the menstrual cup or organic tampons, which have earned shelf space in recent years. It’s a niche product, and many pharmacies don’t even carry it in their catalog. If you ask, they’ll often tell you to special-order it, with a wait of several days and no guarantee the variety or size you need will arrive.

This is a contrast to other countries where sea sponges have been sold for decades in health food shops and herbalists as a natural cosmetic product (for exfoliation, for example) — and only some of those sponges are prepared and certified for menstrual use. If you’re buying at a pharmacy, explicitly ask whether it’s a sponge suitable for menstrual use, not a generic bath sponge.

Where to buy a menstrual sponge online (and what to check first)

Buying online is, today, the main channel for this product in Spain. But not every shop offers the same thing, and this is where your purchase really succeeds or fails:

• Traceable origin. A serious sea sponge should state which sea it comes from and how it’s harvested. Sileu Sea comes from the Caribbean Sea, controlled harvest.
• Hygienic preparation. It should arrive clean, dry and ready for first use, not a relabeled bath sponge.
• Size information. Natural sponges vary piece to piece; a good shop tells you the size range, not just “one size.”
• Clear return policy — though, for hygiene reasons, most shops (ours included) don’t accept returns once the packaging is opened, so your buying decision needs to be informed from the start.

How to choose well: size, texture and density

Unlike a cup or a tampon, which comes out of a mold identical every time, every sea sponge is a distinct natural piece. When choosing, pay attention to three things:

Size. For light-to-medium flow, a small-to-medium sponge is usually enough; for heavy flow, it’s worth getting a somewhat larger piece or changing it more often during the day. If it’s your first time, start with the standard size the shop offers before looking for variants.

Texture. It should feel soft to the touch, with no hard spots or rough edges. A quality sponge compresses easily between your fingers and springs back into shape when released.

Pore density. Small, even pores hold flow better and feel more comfortable; very large, irregular pores usually signal a lower-quality piece, meant more for cosmetic exfoliation than intimate use.

If after reading this you’re still torn between a sponge, a cup or a disc, our general menstrual sponge guide compares all three methods in more detail, and in natural sea sponge: origin, hygiene and care we go deeper into how to clean it between uses so it doesn’t wear out too soon.

How to use a menstrual sponge: the basics

Before buying, it’s worth knowing that using one comes with its own learning curve, different from a cup:

1. Dampen the sponge with clean water (or water with a few drops of water-based lubricant if you notice dryness) before inserting it, so it’s soft and flexible.
2. Compress it between your fingers to reduce its size and insert it the way you would a tampon, no applicator.
3. Give it a few seconds to spring back into shape inside and settle comfortably.
4. Remove it by gently pulling with two fingers; since it has no string or stem, some people prefer to squat the first few times, until they get the hang of it.
5. Rinse it with water before reinserting if you’re reusing it the same day.

It’s precisely this flexible shape that makes the sponge the most discreet reusable option for having sex during your period without a mess, something neither the cup nor conventional tampons handle as well. If you’re traveling with it, store it dry in a breathable SileuCase instead of a sealed plastic bag; our guide on how to travel during your period has more tricks that apply to the sponge too.

Hygiene between uses: what really makes the difference

With a sponge, hygiene isn’t an extra — it’s half the method. Rinse it with warm water after each use during the day, and at the end of your cycle, wash it thoroughly with a mild, unscented soap and let it air dry completely before storing it — storing it damp is the number one cause of a sponge wearing out too soon or smelling bad the next cycle. Avoid the dishwasher, bleach, or very hot water, which damage the porous structure.

Real price: sponge vs. cup vs. tampons

At €9.99, the menstrual sponge is one of the cheapest reusable options to get started, even below the most affordable menstrual cup. It lasts several cycles with proper care, though its lifespan tends to be shorter than a medical-grade silicone cup: a well-cared-for sponge typically lasts 3 to 6 months of regular use, compared to the years a Sileu Classic cup (€14.99) lasts. Even so, the savings compared to buying tampons every month are still real, and the upfront cost is the lowest in the entire reusable catalog.

The scientific evidence on reusable intimate hygiene products, such as the systematic review published in The Lancet Public Health (2019) on menstrual cups (43 studies, over 3,300 participants), supports that well-sanitized reusable alternatives are safe and effective against flow. There’s less published research specifically on sponges than on cups; that’s exactly why we emphasize hygiene so much — it’s the variable that matters most for the safety of this method.

When the sponge is a better choice than the cup

It’s not a universal alternative, but there are situations where it clearly makes more sense than a cup or conventional tampons:

• Sex during your period. With no rigid shape or stem, it’s the most discreet reusable option for having sex during your period.
• A very low or very high cervix, when no cup size quite fits right.
• A preference for 100% natural materials, with no silicone or plastic of any kind.
• Hands with limited grip strength to fold and remove a cup, since the sponge comes out just as easily but without needing to break a vacuum seal.

And when it’s not: if you’re after maximum duration per unit, a very heavy flow that needs widely spaced changes, or you want the backing of the largest body of scientific research, the cup remains the option with the most evidence behind it.
