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.
