Should I Lie on My Left Side After Inserting a Suppository?

When you use a suppository—whether it’s for constipation relief, fever reduction, or to deliver certain medications—your positioning can affect how well it works. Many health professionals recommend lying on your left side after insertion. Here’s what you need to know, based on credible medical sources.

Why Position Matters

Suppositories rely on body heat and close contact with the rectal wall to dissolve and get absorbed. Your anatomy and gravity both play roles:

• Rectum and colon shape
– The rectum leads into the sigmoid colon, which curves up on the left side of your lower abdomen.
– Lying on your left side uses gravity to help keep the suppository in place, close to the absorbing tissues.

• Muscle relaxation
– When you’re lying down, you tend to be more relaxed.
– Relaxed pelvic muscles reduce the chances of the suppository slipping back out.

Recommended Positioning

Most experts suggest the “left lateral” (left-side) position. Here’s how to do it:

1. Prepare a clean, comfortable spot
   • Lay down a towel or pad on your bed or couch.
   • Have tissue or wet wipes within reach.
2. Lie on your left side
   • Bend your left leg slightly toward your chest.
   • Keep your right leg straight or also slightly bent for comfort.
3. Insert the suppository
   • Wash your hands.
   • Unwrap and moisten the tip with water or a water-based lubricant.
   • Gently push the suppository 1–2 centimeters (about ½–1 inch) into the rectum.
4. Remain still for at least 5–15 minutes
   • Give the suppository time to melt and absorb.
   • If you need to get up sooner, press your buttocks together for a moment to help keep it in place.

How Long Should You Stay on Your Left Side?

Guidelines vary slightly, but in general:

• Minimum time: 5 minutes
• Optimal time: 10–15 minutes
• Upper limit: 30 minutes (unless otherwise directed)

Staying too short a time risks expulsion. If you feel cramping or the urge to go too soon, gently press your buttocks together, breathe deeply, and try to relax until the suppository has had time to work.

Exceptions and Variations

• If you have difficulty lying on your left side:
– You can lie on your back with your knees bent and feet flat.
– In some cases, lying on your right side is acceptable—but it’s less effective.

• For children or infants:
– Lay them on their left side or back, with legs gently held or bent.
– Use one hand to stabilize the hips, the other to insert the suppository.

• If you’re bedridden or have limited mobility:
– Ask a caregiver to help with positioning and insertion.
– Always follow any special instructions from your healthcare provider.

Tips for Comfort and Success

• Trim fingernails short and keep hands clean.
• Use gloves or a finger cot if desired.
• Warm the suppository in your fingers for a few seconds to soften it (but not melt it).
• Avoid straining or bearing down after insertion.
• If you feel discomfort, check to make sure the suppository isn’t broken or too large.

What If the Suppository Falls Out?

If you find it on your underwear or bedding:

1. Check if it’s still solid.
2. Wash your hands and gently re-insert a new suppository.
3. If you can’t re-insert, lie still on your left side for a few minutes and apply slight pressure by crossing your legs or pressing your buttocks together.

When Should You Seek Medical Advice?

Most suppositories are safe and have minimal side effects. But contact your doctor if you experience:

• Severe rectal pain or bleeding
• Signs of infection (fever, chills, redness)
• No relief after using the suppository as directed
• Allergic reactions (rash, swelling, difficulty breathing)

You might also consider a free, online symptom check, using the doctor approved Ubie Symptom Checker to help decide if you need to see a clinician.

Additional Considerations

• Dosage timing: Follow the schedule on the package or your prescription label.
• Drug interactions: Let your doctor know about all medications and supplements you take.
• Storage: Keep suppositories in a cool place or refrigerate if the label instructs.

Avoiding Common Mistakes

• Don’t insert a suppository too deeply—1–2 cm is enough.
• Don’t use oil-based lubricants unless specified; they can break down certain types of suppositories.
• Don’t bear down or strain immediately after insertion.
• Don’t ignore severe or persistent symptoms; seek professional help.

Bottom Line

Lying on your left side after inserting a suppository is a simple, effective step to improve absorption and comfort. Aim to stay in that position for at least 5–15 minutes, remain relaxed, and follow any special instructions from your healthcare provider. If you’re ever unsure or experience concerning symptoms, it’s best to speak to a doctor about anything that could be life threatening or serious.
