1. What is Pennsaid?

2. How to Use It

Step	What to Do	Why
1	Clean the area. Wash hands and the skin where you’ll apply the gel.	Reduces infection risk and improves absorption.
2	Apply a thin layer. About 1–2 g (roughly 1–2 tsp) of gel to the affected area.	The label recommends 1–2 g, up to 4 times daily.
3	Cover if directed. If you’re on a dressing (e.g., for a wound) or want extra absorption, you can cover with a bandage.	Some users find it helpful, but it’s optional.
4	Wash your hands.	Prevents accidental exposure to eyes or other skin.
5	Do not exceed the limit. 12 g per 24 h max.	Higher doses increase the risk of side effects.

Tip: Apply on dry skin; avoid applying over large wounds or broken skin unless a doctor says otherwise.

3. Typical Dosage

• Adults & Adolescents ≥12 y: 1–2 g 4 × day (max 12 g/day).

• Pregnancy / Lactation: Use only if the benefit outweighs the risk.
• Elderly / Renal or Hepatic impairment: Start low; monitor for side effects.

4. When NOT to Use Pennsaid

Category	Why
Allergy to diclofenac or any NSAID	Severe hypersensitivity reactions can occur.
Active GI ulcers or bleeding	Even topical NSAIDs can be absorbed systemically enough to worsen GI bleeding.
Severe liver disease	Diclofenac is metabolized hepatically; impaired metabolism increases systemic exposure.
Severe kidney impairment	Diclofenac clearance is reduced; risk of accumulation.
Pregnancy (especially 3rd trimester)	Limited data; may increase risk of premature ductus arteriosus closure.
Lactation	Diclofenac is excreted in breast milk; potential for infant exposure.

5. Common Side Effects

• Local reactions: itching, burning, rash, redness, or dryness at the application site.
• Systemic reactions (rare): headache, dizziness, GI upset, hypertension.
• Serious (rare): hypersensitivity (rash, hives, anaphylaxis), systemic GI bleeding, or liver injury.

If you notice severe skin reactions or any signs of systemic toxicity (e.g., chest pain, severe headache), stop use and seek medical attention.

6. Drug Interactions

Medication	Interaction	Why
Other NSAIDs (oral or topical)	Additive NSAID effect	↑ GI, renal, cardiovascular risks.
Anticoagulants (warfarin, heparin, DOACs)	Increased bleeding risk	Systemic absorption may potentiate anticoagulation.
ACE inhibitors / ARBs	Renal function impact	NSAIDs can reduce renal perfusion.
SSRIs / SNRIs	GI bleeding	Combined NSAID and SSRI/SNRI use raises GI bleed risk.
Diuretics	Electrolyte imbalances	NSAIDs can blunt diuretic effect, leading to fluid retention.

7. Storage & Handling

• Store at room temperature (15–30 °C / 59–86 °F).
• Keep the container tightly closed when not in use.
• Keep out of reach of children; accidental ingestion can lead to systemic toxicity.
• Do not use if the gel is discolored, has a foul odor, or shows signs of contamination.

8. Special Populations

Population	Recommendations
Pregnancy	Only if no safer alternative; discuss with your provider.
Breastfeeding	Generally avoided; diclofenac passes into milk.
Children <12 y	Not approved.
Renal impairment	Dose adjustment and close monitoring.
Hepatic impairment	Use with caution; monitor liver enzymes.

9. Quick FAQ

Question	Answer
Can I use Pennsaid with oral NSAIDs?	Avoid overlapping NSAIDs; risk of additive side effects.
How long does it take to feel relief?	Usually 30–60 min after application; full benefit may take days of consistent use.
Can I use it on the same area as a skin lesion?	Avoid broken or irritated skin unless a doctor says it's safe.
What if I miss a dose?	Resume as soon as remembered; do not double‑dose to compensate.
Is it safe to apply over a wound?	Not recommended unless instructed by a clinician; topical NSAIDs can delay healing.
