An honest comparison of an FDA-approved tablet and a compounded troche: what is known, what is not, and how your physician decides.

Sildenafil is the most prescribed ED medication in the world. Most people know it as the blue pill you swallow 30–60 minutes before sexual activity. FDA-approved sildenafil tablets are available as generics. Some patients also ask about a sublingual troche — a compounded preparation that dissolves under the tongue. This article explains what is and is not known about the two.
When you swallow a standard sildenafil tablet, it is absorbed through the GI tract and passes through the liver (first-pass metabolism) before reaching systemic circulation, where a portion of the drug is metabolized by CYP3A4 enzymes.
From the FDA-approved labeling and clinical trials:
Taking the tablet on an empty stomach or after a light meal helps it work as expected.
A troche is a small lozenge that dissolves under the tongue or between the cheek and gum. A sildenafil troche is a compounded preparation, not FDA-approved — an alternative dosage form, not a generic or an equivalent of the tablet. At YourMD, troches are prepared by a licensed 503A compounding pharmacy (for example Hallandale Pharmacy or Valiant Compounding Pharmacy); the dispensing pharmacy is named on your prescription label.
In theory, absorption through the lining of the mouth could avoid some first-pass metabolism. In practice, onset data for compounded troches are limited, there are no head-to-head trials showing that troches work faster or better than tablets, and the amount absorbed depends on how much of the dose is swallowed rather than absorbed in the mouth.
| Factor | Oral Tablet | Sublingual Troche |
|---|---|---|
| Regulatory status | FDA-approved (generic available) | Compounded, not FDA-approved |
| Onset | 30–60 minutes (established) | Limited data |
| Food effect | High-fat meals delay absorption | Not well studied |
| How to take | Swallow with water | Dissolve in the mouth |
| Who makes it | FDA-approved manufacturers | Licensed 503A compounding pharmacy (named on your label) |
| Price at YourMD | $59/month | $89/month |
If your physician prescribes a troche, follow the pharmacy label. Generally: place it under the tongue or between the cheek and gum, let it dissolve completely, and avoid eating, drinking, or swallowing excessively while it dissolves.
For most men, your physician will start with FDA-approved oral sildenafil or tadalafil, which have the strongest evidence.
The same drug reaches the same receptors, so the side effect profile is expected to be similar: headache, facial flushing, nasal congestion, indigestion, and rarely visual changes.
Safety rules for every form of sildenafil: never take it with nitrates (including “poppers”) or riociguat; use caution with alpha-blockers; your physician will confirm you are fit for sexual activity. Seek emergency care for chest pain or an erection lasting more than 4 hours, and stop and seek urgent care for sudden vision or hearing loss.
This article compares delivery methods for the same drug. If you are deciding between sildenafil and tadalafil as different medications, the comparison involves duration (4–6 hours vs up to 36 hours), daily vs as-needed dosing, and BPH benefits.
