                  CONNETICS REPORTS FOURTH QUARTER EPS OF $0.17
                  AND PRODUCT REVENUES UP 128% TO $43.5 MILLION

              CONCLUDES FIRST YEAR OF PROFITABILITY WITH $0.52 EPS

          PROVIDES FULL YEAR AND FIRST QUARTER 2005 FINANCIAL GUIDANCE

PALO ALTO, CALIF. (JANUARY 25, 2005) - Connetics Corporation (Nasdaq: CNCT), a
specialty pharmaceutical company that develops and commercializes dermatology
products, today reported record net income for the 2004 fourth quarter of $6.4
million, or $0.17 per diluted share, compared with $1.5 million, or $0.05 per
diluted share, for the comparable quarter last year.

Total revenues for the fourth quarter of 2004 rose 115% to $43.8 million,
compared with $20.3 million for the fourth quarter of 2003. Product revenues
rose 128% to $43.5 million, reflecting $22.6 million in sales of OLUX(R) and
Luxiq(R), $18.0 million in sales of Soriatane(R) and $2.9 million in sales of
Evoclin(TM), which was launched in December 2004. Combined OLUX and Luxiq
revenues increased 19% compared with the fourth quarter of 2003.

Selling, general and administrative (SG&A) expenses increased to $22.8 million
in the fourth quarter of 2004 from $10.1 million in the fourth quarter of 2003,
primarily due to payments made to UCB Pharma (UCB) for promotional activities on
behalf of OLUX and Luxiq, launch-related costs for Evoclin, increased
promotional activities for all products and increased headcount primarily
related to Connetics' salesforce expansion. Research and development (R&D)
expenses were $5.7 million, down from $6.5 million in the fourth quarter of
2003.

"Strong product revenue growth during 2004 contributed to our first full year of
profitability and the fifth consecutive year of growth in our core brands OLUX
and Luxiq," said Thomas G. Wiggans, President and Chief Executive Officer of
Connetics. "Our first product in the acne market, Evoclin, was approved and
launched during the fourth quarter. While early in the launch phase, the
prescription data has been strong and the feedback from physicians has been
encouraging, which we believe bodes well for a dynamic and expanding presence
for Connetics in the acne market. We also marked the success of 2004 with the
acquisition of Soriatane. Through our promotional efforts Soriatane was a
significant financial contributor in 2004 and also was an important product for
patients. With four marketed brands, a substantially expanded commercial team
and a robust product pipeline, we believe Connetics is poised for another
exciting and highly productive year."

Significant activities in the fourth quarter of 2004 and subsequent weeks
included:

     o    Receiving U.S. Food and Drug Administration (FDA) approval of Evoclin
          (clindamycin Foam, 1%) for the topical treatment of mild-to-moderate
          acne vulgaris, and the commencement of shipments to pharmaceutical
          wholesalers, retail pharmacies, hospitals and other institutional
          customers nationwide.
     o    Launching a comprehensive sales and marketing program for Evoclin that
          is expected to include a strong presence at relevant medical
          conferences, particularly in the first quarter of 2005, by way of
          poster and symposia presentations, as well as journal advertising,
          direct promotion, media relations and internet marketing campaigns.


     o    Hiring 66 sales professionals, which more than doubled the salesforce
          to 124 professionals and positions Connetics as a strong commercial
          force in the dermatology market.
     o    Receiving an FDA non-approvable letter for the Company's product
          candidate Extina(R). The Company plans to meet with the FDA early in
          2005 to discuss the actions required to obtain approval for Extina.

2004 FULL YEAR FINANCIAL RESULTS
Net income for 2004 was $19.4 million, or $0.52 per diluted share, which
includes a third quarter $3.5 million milestone payment to Yamanouchi associated
with the filing of the Velac(R) New Drug Application. This compares with a net
loss of $4.1 million, or $0.13 per share, for 2003.

Total revenues for 2004 rose 92% to $144.4 million, and product revenues
increased 113% to $142.1 million, reflecting growth in OLUX and Luxiq, the
addition of Soriatane in March and the launch of Evoclin in December.

SG&A expenses increased to $71.9 million for 2004, compared with $40.9 million
for 2003, primarily due to payments made to UCB for promotional activities
related to OLUX and Luxiq, increased promotional activities for all products and
increased headcount. R&D expenses for 2004 were $21.0 million, down from $29.6
million during 2003 primarily due to the completion of pivotal trials with
Extina, Evoclin and Velac.

Cash and investments, including restricted cash, totaled $76.3 million on
December 31, 2004.

2005 FULL YEAR AND FIRST QUARTER FINANCIAL GUIDANCE
Connetics expects 2005 total revenues to be between $190 million and $200
million, representing an increase of 32% to 39% compared with 2004. Combined
SG&A and R&D expenses are projected to be between $116 million and $123 million.
Diluted EPS for 2005 is projected to grow by approximately 70% and to be in the
range of $0.88 to $0.92, based on an estimated 42.3 million shares outstanding
and an estimated effective tax rate of 10%. Assuming FDA approval of Velac
during 2005, the Company anticipates making a milestone payment of $5 million to
Yamanouchi. This payment will be capitalized and amortized over the life of the
patent, which expires in 2014.

The Company expects first quarter 2005 total revenues to be between $42 million
and $44 million. Consistent with prior years of heavier expenditures in the
first quarter compared with the immediately preceding quarter, Connetics
projects combined SG&A and R&D expenses for the first quarter to range from
$33.5 million to $35.5 million, reflecting a significant presence at dermatology
conferences during the quarter, an increase in product promotion costs,
particularly the Evoclin launch, and higher costs associated with a
significantly expanded salesforce. Connetics projects net income per share for
the first quarter of 2005 of $0.01 or $0.02.

In assessing the Company's financial guidance, Connetics' management considered
many factors and assumptions including, but not limited to, current and
projected prescription information; sales trend data; the potential generic
availability of, and competitive threats to, the Company's products; size, reach
and call frequency of the Company's selling organization; status, timing and
progression of the Company's development projects; current and projected
spending levels to support sales, marketing, development and administrative
activities; and other risk factors discussed in Connetics' publicly filed
documents. The above guidance does not take into account the effect of expensing
stock options.
