Side Effects

Side effects are dose-related. At 200 mg, expect them to be markedly more frequent and more intense than at 100 mg.

Side Effect	Frequency	What To Do
Headache	Very likely at this dose	Rest and hydrate; consider a lower dose
Facial flushing or warmth	Very likely at this dose	Settles as the drug wears off
Blurred or blue-tinged vision	Substantially increased	Do not drive; tell your doctor
Light sensitivity	Substantially increased	Avoid bright screens and sunlight
Indigestion or heartburn	Common	Avoid heavy or spicy meals
Blocked or runny nose	Common	Temporary; no treatment usually needed
Dizziness	Common	Sit or lie down; do not drive
Nausea	Common	Take with a light snack next time
Back pain or muscle ache	Common	Usually resolves within 24 hours
Rapid or pounding heartbeat	Increased at this dose	Rest; seek advice if it persists
Low blood pressure symptoms	Increased at this dose	Stop use; seek medical advice
Nosebleed	Less common	Apply pressure; report if repeated
Dry mouth or altered taste	Less common	Sip water regularly
Skin rash or itching	Less common	Stop use and contact your doctor
Ringing in the ears	Less common	Report to your doctor
Fainting or near-fainting	Uncommon	Stop use; seek medical care
Chest pain	Rare	Emergency; see section 8
Priapism (erection over 4 hours)	Rare	Emergency; see section 8
Sudden vision loss (NAION)	Rare	Emergency; stop use permanently
Sudden hearing loss or tinnitus	Rare	Emergency; stop use immediately
Seizure	Very rare	Emergency; call for help
Severe skin reaction with blistering	Very rare	Emergency; stop use immediately

Vision is the effect most affected by dose. Blue tinting, blurring, and light sensitivity all become considerably more likely at 200 mg. If your vision changes, do not drive and tell your doctor.

If side effects trouble you at 200 mg, a lower dose will almost certainly work just as well. The erectile benefit does not increase above 100 mg.

Drug Interactions – Avoid With

Never combine (dangerous):

Use only with medical supervision and dose adjustment:

These drugs raise sildenafil blood levels. Combining any of them with 200 mg is especially risky.

May reduce effectiveness:

Always show your doctor a full list of your medicines.

Emergency Warning Signs

Stop the medicine and seek emergency care immediately if you experience:

Tell emergency staff you have taken sildenafil. State the dose as 200 mg, which is double the standard maximum. They must not give you nitrate medicines. Untreated priapism can cause permanent erectile damage within hours.
