What is a compounded medication?

A compounded medication is prepared by a specialist compounding pharmacy to a specific formula prescribed by your doctor. Unlike mass-produced medications, compounded preparations can combine multiple active ingredients, adjust concentrations, and use specific bases (cream, ointment, gel) tailored to your needs. For fissures, common compounded preparations include combinations of diltiazem, nifedipine, lidocaine, and other agents.

Why would I need a compounded medication instead of a standard one?

Compounded medications are often used when standard preparations are not available in your country, when a specific concentration is needed, when multiple active ingredients are combined (such as a muscle relaxant with a pain-relieving agent), or when you have had side effects from standard formulations and need an alternative.

Are compounded medications as effective as standard ones?

Compounded medications use the same active ingredients as standard preparations. When prepared by a reputable compounding pharmacy to a specific formula, they are expected to work similarly. However, because each preparation is individually made, consistency can vary between batches. Using a trusted, accredited compounding pharmacy is important.

Are compounded medications more expensive?

They can be. Compounded medications are individually prepared, which often makes them more expensive than mass-produced alternatives. Insurance coverage varies. Some people find the cost worthwhile for a preparation that is better tolerated or more effective for their specific situation.

Compounded medications for fissure

At a glance

Compounded medications for anal fissures are custom-prepared formulations that combine active ingredients tailored to your treatment needs. They are used when standard commercial preparations are not available, not tolerated, or not sufficient. This guide explains what they are and what to expect.

What compounding means

When your doctor prescribes a compounded medication, a specialist compounding pharmacy prepares it specifically for you. This is different from a standard prescription, where a mass-produced medication is dispensed from stock.

Compounding allows:

Custom concentrations — the amount of active ingredient can be adjusted
Combination formulas — multiple active ingredients in one preparation
Alternative bases — cream, ointment, or gel, depending on what works best for the application site
Allergen avoidance — removing specific ingredients that cause reactions

Common compounded preparations for fissures

Diltiazem cream

Diltiazem is a calcium channel blocker that relaxes the sphincter muscle. It is available commercially in some countries but is often compounded in others. Concentrations typically range from 2% to 5%, depending on the prescribing clinician’s preference.

Nifedipine cream

Another calcium channel blocker, sometimes used as an alternative to diltiazem. Often compounded in combination with lidocaine for pain relief.

Combination preparations

Some clinicians prescribe combinations such as:

Diltiazem with lidocaine (muscle relaxation plus pain relief)
Nifedipine with lidocaine
Multiple agents combined based on the clinical picture

The specific combination depends on your clinician’s approach and your previous treatment history.

Using compounded medications

Application

The application method is the same as for standard topical fissure treatments:

Clean the area (sitz bath or gentle wash)
Apply a small, prescribed amount to the anal margin using a gloved finger
Wash hands thoroughly
Repeat at the prescribed frequency

Storage

Compounded medications may have specific storage requirements — often refrigeration. They also typically have a shorter shelf life than commercial products. Check the label and follow the pharmacy’s instructions.

Consistency

Because each batch is individually prepared, there may be slight variations in texture or appearance between refills. If a new batch seems significantly different — a different colour, consistency, or smell — contact the pharmacy to confirm it was prepared correctly.

Cost and access

Compounded medications are generally more expensive than standard prescriptions because of the individual preparation involved. Availability depends on having a compounding pharmacy that can prepare the formulation your doctor prescribes.

If cost is a concern, discuss with your clinician whether a commercially available alternative might be appropriate for your situation.
